mentioned in merge request !389 (merged)

Thanks for the fix. The fix works for the dynamic link. However, I got link error for static link when using with cmake command. Note that static link is a must in our testing environment.

cmake -DCMAKE_FIND_LIBRARY_SUFFIXES=".a" -DBUILD_SHARED_LIBS=OFF -DCMAKE_EXE_LINKER_FLAGS="-static" path

The link errors are as follows

/usr/bin/ld: attempted static link of dynamic object `/usr/lib/gcc/x86_64-linux-gnu/12/libgomp.so'

It is interesting that I had the above link errors for VTM11ECM8 only, not for ECM, not for VTM. I have not figured what was wrong.

did you try to do a clean build?

Yes, removed everything, regenerated makefile with cmake and then compile.
