[ 40%] Linking CXX shared module _func.so cd /build/reproducible-path/openturns-1.26/builddir/python/src && /usr/bin/cmake -E cmake_link_script CMakeFiles/func.dir/link.txt --verbose=1 E: Build killed with signal TERM after 720 minutes of inactivity The patch below does the following: 1. Debug information is useful, but it can take a surprising large part of the build time. As a workaround, reduce debug information on riscv64. 2. I have not verified whether this helps with the build hang on the real-hardware Alpha buildd, but let's try 1. also there. 3. What got the build killed was one linker invocation that took longer than 12 hours. mold is a much faster linker, use it on riscv64. The combination of 1. and 3. made the riscv64 build go from one linker invocation getting killed after 12 hours to a successful build after 9.5 hours.
Thank you for your bug report and the explanations, this is much useful!
This is just a workaround: Faster buildd hardware would help with both. Item 1 is an issue where it is unclear whether improvements are possible, I'll gather data for a bug report for the linker issue in item 3.
Understood. Should I wait for your bug report related to item 3 before uploading with the workaround you suggest?
Best regards, -- Pierre
