Title

Build Failure on METv12.0.0-rc1 at proj Section on Ubuntu 24 with GNU Compilers and Python 3.12

Issue Description

The METv12.0.0-rc1 release candidate fails to build on a non-HPC system during the proj library compilation phase. This issue occurs on Ubuntu 24 using modern GNU compilers and Python 3.12. The installation process does not progress past the library compilation stage, which deviates from the behavior observed in the stable version v11.1.0, where the installation completes successfully.

Expected Behavior

MET should compile and install all libraries successfully, similar to its behavior in version v11.1.0.

Environment

• Machine: Linux Workstation
• Operating System: Ubuntu 24.4.1
• Python Version: 3.12.3
• Compiler: GNU 13.2.0

Steps to Reproduce

The issue can be observed by following the steps outlined in the provided log files. Unfortunately, I cannot attach files directly here, but I am happy to provide them upon request or share through an alternative method.

UBUNTU_24.zip

Current Workaround

I attempted a possible solution by modifying the compile script at line 532. The modification included adjusting the cmake flags to ensure compatibility with the current setup:

cmd="cmake -DCMAKE_INSTALL_PREFIX=${LIB_DIR} -DCMAKE_CXX_STANDARD=17 -DCMAKE_CXX_FLAGS='-include cstdint' -DINCLUDE_CSTDINT=ON -DSQLITE3_INCLUDE_DIR=${SQLITE_INCLUDE_DIR} -DSQLITE3_LIBRARY=${SQLITE_LIB_DIR}/libsqlite3.${dynamic_lib_ext} ${tiff_arg} .. > $(pwd)/proj.cmake.log 2>&1"
run_cmd ${cmd}
run_cmd "cmake --build . > $(pwd)/proj.cmake_build.log 2>&1"
run_cmd "cmake --build . --target install > $(pwd)/proj.cmake_install.log 2>&1"

Despite these changes, I am uncertain of the installation's success since the output differs from what was seen in version v11.1.0.

Request

I would appreciate guidance on whether there are known issues with MET version 12.0.0-rc1 and this specific environment, or suggestions on further modifications to the compile script that could resolve the problem.
