On the other side the compilers -fuse_ld parameter needs an executable script. Is there a way to circumvent this. The only fallback I'm aware of would be to keep the script local and just commit a configure parameter which provides the path to the local script setting then -fuse-ld accordingly. Are there other solutions possible? ------------- PR Comment: https://git.openjdk.org/jdk/pull/23313#issuecomment-2619249331
