Some build errors on Windows system(msys2) #19

asmwarrior · 2020-07-04T08:00:39Z

I have msys2, and have its 64bit GCC compiler install.
When using the cbp file under Code::Blocks, I see some build errors, such as this one:

There are some other build errors, but let's fix them one by one.

Ah, yes. I was careless with the path conversions because this has been a slow effort to generalize the initialization logic from a bunch of commands I've been running manually on my own machine. In this case, just calling u8string() first is a quick fix, but the better solution is to leverage the new path API and have llreader accept it instead of a bunch of hacked-up char* overloads.

The quick fix is now in the twenty branch. See #17.

JoshDreamland · 2020-07-05T04:04:54Z

You might have better luck with the Test target, assuming you have GoogleTest handy. The main method of the Debug target depends on ENIGMA's game engine source for input data, but the tests are totally hermetic.

Only issue is that they're still rather small. I'm building them up with corner cases which JDI was originally written to gloss over—things that usually don't matter for code completion. The new C++ standards expose the entire language very explicitly, so I'm having to recode large chunks to look more like pages out of the standard.

I'm on this branch, but the same error still exits.

asmwarrior · 2020-07-09T04:19:05Z

The problem is: std::filesystem::path

Here, I see that in the document: std::filesystem::path - cppreference.com, and the document said:

value_type character type used by the native encoding of the filesystem: char on POSIX, wchar_t on Windows
std::filesystem::path::c_str, this accesses the native path name as a character string.

So, on Windows, c_str() also return the native character type string, which is wchar_t type.

But incfile.open() need a char* type string.

JoshDreamland · 2020-07-09T04:24:31Z

I just missed a file. I fixed Main but not lex_cpp. Calling u8string().c_str() is the workaround. Alternatively, it'd be better to replace the llreader constructor and open() routine to just accept const std::filesystem::path & instead. But I can't remember if CreateFileW takes the exact same parameters (it's proper to instead call it with the wide string version, CreateFileW(filename.u16string().c_str(),...).

Patching lex_cpp.cpp to just call u8string() first is easier, but if you're willing to try out the CreateFileW patch, that'll solve this for the longer term.

asmwarrior · 2020-07-09T04:29:09Z

I'm using such code: incfile.open((incfn = cur_path / fnfind).string().c_str());, which is also OK.

You can create a branch, and then I can test it? CreateFileW is a native Windows API, and we could use the std's function if possible?

JoshDreamland · 2020-07-09T04:31:49Z

Eh, Windows build's already broken. We'll get CI set up for it eventually. In the meantime, can't do worse than broken build. Pushed it as e44072c.

It might be worth turning of -Werror in the build settings (or building with cmake). I hold myself to -Wpedantic-errors when building locally, but that's probably not the best way to get it running for you right now.

Oh, also worth noting that path.string() will not necessarily behave correctly in C++20. It might return the wide string type. Explicitly asking for u8string/u16string should work out, though.

OK.

asmwarrior · 2020-07-09T04:46:59Z

Please note that there is no function under Windows like:

signal(SIGTRAP, donothing);

If I comment out this function, than I get

F:\code\justdefineit\JustDefineIt\src\System\lex_cpp.cpp:45:13: error: 'void donothing(int)' defined but not used [-Werror=unused-function]

So, I have to turning of -Werror in the build settings. I'm using cbp file.

JoshDreamland · 2020-07-09T04:58:42Z

Oof, no catching SIGTRAP, either? That's fine; there is logic elsewhere that raises SIGTRAP using an inline assembly block, but only if the code being parsed contains #pragma DEBUG_ENTRY_POINT. I added the signal handler to avoid crashing when running with no debugger attached.

Turning off Werror is probably for the best, at this point. Let me know if anything else is still broken.

I can build the exe file (The Debug target in Code::Blocks project)
Now, what is the way to simply test the parser?

When I run the target, it gives such command line messages:

Usage: JustDefineIt <c++std> </path/to/enigma> <test_lexer>
Will assume default values.
terminate called after throwing an instance of 'std::filesystem::__cxx11::filesy
stem_error'
  what():  filesystem error: cannot create directory: No such file or directory
[/tmp/jdi]

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

Process returned 3 (0x3)   execution time : 43.420 s
Press any key to continue.

Maybe, the path is different with Linux and Windows.

My question is: Is it possible to simply let the parser parse a single header file. Such like:

JustDefineIt test.h

JoshDreamland · 2020-07-09T14:48:45Z

I can throw one together this evening for you to play with. As long as you only need C++03, you should see decent results. The target you're building is configured to parse a specific project of ours, and so it defines include directories and macros specific to that engine.

JoshDreamland · 2020-07-10T04:53:47Z

I cut the general parts out of the old main and into a new one under a new "Demo" build target (dcdce97).

I am not certain it will build for you, but I've done my best on that front. I threw in a macro that preprocesses away __attribute__. This is one of the training wheels I recently removed from the project to try to get it up to shape with C++11 and beyond. But without that, it can't correctly read, eg, std::string, which greatly damages future code comprehension. With the macro in place, it works reasonably well:

> d std::string
Enter the item to define:
>> typedef basic_string<char, char_traits<char><>, allocator<char>> string;

...ignoring a CLI quirk in switching from getch() to cin. You can see where I defined it on line 249.

Cheers

Oops. I created a blank_file variable to work around that, but I only plugged it into one of the two commands. Pushed a fix to use it in the other command in 03421f7.

And yes, at some point, I should merge the logic here with that in our original MAIN.cc. I'm thinking I can move these calls directly into builtin.cpp. I'd have done so already, but I dislike the reliance on temp files. Fortunately, std::filesystem makes that vastly more convenient.

Is nul a Windows idiom I've missed, or is it a file you created?

asmwarrior · 2020-07-11T04:08:01Z

Under Windows, there is no such command(tool):

          if (show) {
            a.writeSVG("/tmp/anus.svg");
            if (system("xdg-open /tmp/anus.svg"))
              std::cout << "Failed to open." << std::endl;
          }

Is there any way I can print/view the whole parsing tree?

Here is my log, which seems correct, but I'd like to check how the parser is parsing a simple file:

Is nul a Windows idiom I've missed, or is it a file you created?

See here: linux - What is a cross-platform compatible way to redirect to NUL or /dev/null? - Stack Overflow

Under Code::Blocks' source code, we use something similar like:

    //   Windows: mingw32-g++ -v -E -x c++ nul
    //   Linux  : g++ -v -E -x c++ /dev/null
    // do the trick only for c++, not needed then for C (since this is a subset of C++)

    // Different command on Windows and other OSes
#ifdef __WXMSW__
    const wxString args(_T(" -v -E -x c++ nul"));
#else
    const wxString args(_T(" -v -E -x c++ /dev/null"));
#endif

JoshDreamland · 2020-07-11T04:12:22Z

Ah. Well, you can also just populate search dirs manually the same way the functions in that routine does. Our game engine also has that info lying around, which is why I never moved it into the API.

JoshDreamland · 2020-07-11T04:20:23Z

And before you ask, here's a breakdown of some oddities you'll see in the output:

    inline void swap(<null> &_Tp, <null>, <null> &_Tp);

The argument types aren't known (parsing error).

    template<typename _Iterator> inline (?=reverse_iterator<_Iterator>::difference_type) operator-(const reverse_iterator &__x, const reverse_iterator &__y);
    // ...
    typedef (?=__truth_type<__value>::__type) __type;

The types are kind of known (they're dependent types).

    typedef __locale_t __c_locale (typedef __locale_struct *__locale_t;)

Printing error (not so pretty print I hacked together for inspection).

Also probably a few thousand parse errors in general. Some from missing features, some from bugs. Working on it, slowly.

JoshDreamland · 2020-10-01T02:01:04Z

Perhaps moving #include "llreader.h" to the top of llreader.cpp will fix it? The problem seems to be a build error just from including headers in that order, which shouldn't happen. My guess is just #include <windows.h> followed by #include <string> will reproduce it, in which case it's a MinGW/msys bug. Can you check?

Yes, this fixes the build issue, thanks for the help!

The problem seems to be a build error just from including headers in that order, which shouldn't happen. My guess is just #include <windows.h> followed by #include <string> will reproduce it, in which case it's a MinGW/msys bug. Can you check?

I just create a simple test code like below:

#include <string>
#include <windows.h>

using namespace std;

int main()
{

    return 0;
}

And it builds OK without any issue.

asmwarrior · 2020-10-01T04:07:48Z

You want the d command. Use d :: and it'll just dump everything.

It looks like this command does not dump everything, it just print the namespace.

I have this code to be parsed:

// my_class.h
namespace N
{
    class my_class
    {
    public:
        void do_something();
    };

}

Then here is the command result:

> d ::
Enter the item to define:
>> {
  namespace N {
  }
}
>

Does this command only print the namespace recursively? It does not print the symbol void do_something();. Thanks.

JoshDreamland · 2020-10-03T02:15:12Z

Ugh. No, sounds as though I've broken something. I haven't finished integrating the newly-merged master with our own codebase yet, so not terribly surprising I missed something in my cursory inspection. What's odd is that I confirmed the system recognized our own structures, so perhaps this is a recent regression I didn't think to look for.

I'll get some unit tests added for this and we can hopefully avoid this problem in the future. Thanks for the update!

JoshDreamland · 2020-10-06T04:47:08Z

Yeah, it was a regression. While I was replacing all JDI's internal pointer types with unique_ptr, I noticed struct definitions were being written to the same pool as other definitions, meaning there was no way to correctly have a class and non-class with the same name in one scope. I fixed that, breaking some of the reflection on types. Pushed a fix, as well as unit tests, to the twenty branch.

I've gone ahead and merged it into master. No sense turning back, at this point.

asmwarrior · 2020-10-06T06:18:25Z

OK, It now print the member function. Good work!

BTW, I have a lot of changes in my local copy against the master HEAD. Which make the cbp build under Windows(I'm using code::blocks + Msys2)

Here is first patch:

It looks in such line bool _inline = token.type == TT_DECFLAG && token.content.toString() == "inline";

int context_parser::handle_declarators(definition_scope *scope, token_t& token,
                                       unsigned inherited_flags,
                                       definition* &res) {
  // Skip destructor tildes; log if we are a destructor
  bool dtor = token.type == TT_TILDE;
  bool _inline = token.type == TT_DECFLAG && token.content.toString() == "inline";
  if (dtor) token = read_next_token(scope);

  // Outsource to read_fulltype, which will take care of the hard work for us.
  // When this function finishes, per its specification, our token will be set to the next relevant, non-referencer symbol.
  // This means an identifier if the syntax is correct.
  full_type tp = read_fulltype(token, scope);
  if (dtor) {
    if (tp.refs.name.empty() && tp.def == scope && !tp.flags &&
        tp.refs.size() == 1 && tp.refs.top().type == ref_stack::RT_FUNCTION) {
      tp.refs.name = "~" + scope->name;
      tp.def = builtin_type__void;
    } else {
      token.report_error(herr, "Junk destructor; remove tilde?");
      FATAL_RETURN(1);
    }
  }

Any idea how to fix this build error, I have to comment out the part after the && to work around this issue, but this is not a solution.

workaround:

The compiler you're using seems to have some serious problems... that, or Windows has reserved _inline. In theory, only __inline would be reserved for the compiler. Anyway, renaming it to is_inline should work.

Thanks for the patches! I'll apply them tonight. Might be easier to just commit them to a local fork and drop a pull request. Or I can give you access to push them as a branch, if you like.

asmwarrior · 2020-10-07T01:00:12Z

I can start a pull request, but I think a lot of my patches should be modified, because it will break the Linux build.

That's the reason I post the patch contents here in the comments.

JoshDreamland · 2020-10-07T04:02:43Z

Ah, I understand. Nope, don't worry about it. I'll update the code around the patched areas to use newer C++ features instead of relying on platform-specific code. Looks as though most of these patches are for things covered by std::filesystem, or small oversights my compiler doesn't care about.

Thanks for the pointers!

One question: why does your implementation not support <csignal>? It's been standard since the beginning of time. Microsoft even lists it, here: https://docs.microsoft.com/en-us/cpp/standard-library/csignal?view=vs-2019

Is it just the SIGTRAP macro? I can replace it with 3.

Yes, it is just SIGTRAP macro.

Still haven't figured out that header order problem. I think maybe you need to enable STL debug mode to reproduce it, but I still think it's the include order of <windows.h> and <string>. It would be good to hunt that down, as I'm pretty sure it's a library issue. My guess would be #define reference appearing somewhere in the Windows headers.

Regardless, the include belongs at the top of the file, anyway, and I've applied those patches or a similar fix and created #21 to merge them. I am hoping that branch will build for you without error. It might be good to have a dump of all the compiler warnings so I can take a crack at those, but I'm sure I'll generate more when I go to add support for parameter packs and decltype.

asmwarrior · 2020-10-13T14:33:27Z

I'm building the PatchesForWindows branch, and it build successfully under MSYS2 + CodeBlocks.
Good work!

JoshDreamland · 2020-10-13T15:11:08Z

Excellent. Also, fundies went ahead and added a MinGW build to the CI, so we should be able to avoid future breakages that way.
