[ 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.
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.
