3.8.0: Getting a g++ error when compiling server.cpp

[mchch007]

Apologies upfront if this is already known; I am new here.

If am doing anything wrong instead, as the problem is often sitting in front of the machine, just let me know.

Here is my description:

When compiling in a Ubuntu 20.04 environment, which is also the target one, I am getting a g++ error.
Previous compilations in the same environment went well.

My machine:

Can you detail your build steps?

[rdica]

I fired up a Ubuntu Focal 20.04 VM, installed the deps, and successfully compiled.

[mchch007]

Could you share your server.cpp file? I'd like to give it a try and/ or compare it to my version.

[mchch007]

Build steps are just downloading the sources as described and running makefile. Other cpp are compiled well, just the server.cpp compilation comes back with the error after freeze of some 3 to 4 minutes....

[rdica]

I don't know what you mean "running makefile".
The build steps are:

• cd $SRC_DIR
• qmake Jamulus.pro
• make clean && make

These are the steps as outlined on github. Are these the steps you followed as well?

[mchch007]

Sorry for not having been clear. I did exactly those steps.

This looks like GCC is running out of memory and getting killed - the errors from the assembler are just because GCC gave up writing the assembly output partway through. How much memory does your VM have?

[mchch007]

Thanks for notifying. My small VM has 1 GB. I will setup a bigger one and retry. Will be able to do this only during the weekend. Will come back with the result.

[mchch007]

Wow, that was it! Thanks so much!
As my server is also running as a small "production" for Jamulus, I wanted to avoid rebuilding the whole thing, and instead could free up some 300M memory by stopping a second application not needed anymore. This have me some 450M available memory
(MiB Mem : 976.6 total, 431.6 free, 129.4 used, 415.7 buff/cache), and that was it for compiling.
Again, thanks for your valuable answers and support!
