GCC 13.1 requires '#include <cstdint>' in several headers

[ligh_de]

Trying to compile VVC in MSYS2/MinGW64 using GCC 13.1 fails, the same error as in many other projects since GCC got updated from v12 to v13:

Probably at least the following files need an additional #include <cstdint>:

• source/Lib/CommonLib/CommonDef.h
• source/Lib/CommonLib/TypeDef.h
• source/Lib/CommonLib/dtrace.h
• source/Lib/CommonLib/Hash.h
• source/Lib/Utilities/program_options_lite.h

1 week without any reaction. Is this project abandoned?

Thanks for the report. So far, I have not been able to install gcc-13.0 in our working environment . If your fix works, maybe you could submit an MR to fix the issue. You may check the workflow here ​https://vcgit.hhi.fraunhofer.de/jvet/VVCSoftware_VTM/-/wikis/VVC-Software-Development-Workflow. On the other hand, maybe you could also try other gcc versions, such as gcc-12.2. For other compilers, I just tried clang 14 and it also worked.

I am not really a developer, just a half-wit. I usually run the ​media-autobuild suite which keeps itself up to date to the recent state of the MSYS2 project. If MSYS2 updates GCC to version 13, I can't just downgrade it: dozens of other modules, most of them linked into ffmpeg, rely on its consistency.

I am not very used to working with git. I learned to create Merge Requests by editing files in the web view of repositories hosted on github, but I have no experience on gitlab. Also I don't know your project well so I can't be sure that my solution is sufficient. For m-ab-s I created a patching script using sed:

vvc_extra.sh

_pre_ninja() {
    sed -i 's!#include <cstdlib>!#include <cstdlib>\n#include <cstdint>!' ${REPO_DIR}/source/Lib/CommonLib/CommonDef.h
    sed -i 's!#include <cstddef>!#include <cstddef>\n#include <cstdint>!' ${REPO_DIR}/source/Lib/CommonLib/TypeDef.h
    sed -i 's!#include <cstdarg>!#include <cstdarg>\n#include <cstdint>!' ${REPO_DIR}/source/Lib/CommonLib/dtrace.h
    sed -i 's!#include <vector>!#include <cstdint>\n#include <vector>!' ${REPO_DIR}/source/Lib/CommonLib/Hash.h
    sed -i 's!#include <vector>!#include <cstdint>\n#include <vector>!' ${REPO_DIR}/source/Lib/Utilities/program_options_lite.h
}

I submitted ​https://vcgit.hhi.fraunhofer.de/jvet/VVCSoftware_VTM/-/merge_requests/2616

Compiles for me with fewer changes.

The MR was merged.

Yes, compiles in m-ab-s as well; thank you.
