Building dependencies fails: try: 'make depend'

Configuring MLDonkey 3.2.1 completed.

Network modules:
 - eDonkey           enabled (eMule SUI enabled)
 - BitTorrent                disabled - ocaml num library missing (must be installed manually when building with OCaml >= 4.06)
 - FileTP (aka wget) enabled
 - Fasttrack                 disabled
 - Gnutella                  disabled - unmaintained
 - Gnutella2                 disabled - unmaintained
 - Direct Connect    enabled
 - Open Napster              disabled - currently not usable
 - Soulseek                  disabled - currently not usable
 - OpenFT                    disabled - currently not usable

Core features:
 - zlib (required)   enabled
 - threads           enabled
 - bzip2             enabled
 - iconv             enabled
 - libmagic          enabled
 - upnp & natpmp             disabled
 - graphical stats           disabled

Compilers:
 - OCaml version     5.1.1 
 - gcc version       14.1.1
 - g++ version       14.1.1

\nNow execute 'make' to start compiling. Good luck!

To compile a static code execute:     make mlnet.static
To produce a release tarball execute: make release.mlnet.static
To clean the build directory execute: make maintainerclean

Compiling CryptoPP.cc can take several minutes, on slow machines up to half an hour.

Try building with a single job.

[LoongUser77]

Hi,

I used -j because I obtain more logs, but with 1 job it fails too:

make
/usr/bin/ocamlc.opt -w +a-3-4-6-27-29-32-35-37-41-44-45-48-60-70   -I src/utils/extlib  -I src/utils/cdk  -I src/utils/bitstring  -I src/utils/lib  -I src/utils/ocamlrss  -I src/utils/xml-light  -I src/utils/net  -I tools  -I src/daemon/common  -I src/daemon/driver  -I src/utils/mp3tagui  -I src/config/unix  -I src/networks/direct_connect  -I src/networks/fileTP  -I src/networks/donkey -I +camlp4  -c tools/ocamlpp.ml
File "_none_", line 1:
Alert ocaml_deprecated_auto_include: 
OCaml's lib directory layout changed in 5.0. The str subdirectory has been
automatically added to the search path, but you should add -I +str to the
command-line to silence this alert (e.g. by adding str to the list of
libraries in your dune file, or adding use_str to your _tags file for
ocamlbuild, or using -package str for ocamlfind).

Thanks!

[ygrek]

build with OCaml 5 is expected to fail yet
this is mentioned in 3.2.0 release notes https://github.com/ygrek/mldonkey/releases/tag/release-3-2-0
will keep this issue open to track the status of ocaml 5 support

[LoongUser77]

Thanks! I will wait, meanwhile I'll use amule, but I prefer mldonkey.

[carlonluca]

You can use docker, which is very convenient, if building is a problem.
