Description Tee KOBAYASHI 2021-05-26 20:44:31 UTC

When cross-emerging dev-libs/openssl for *-w64-mingw32, libssl.dll.a and libcrypto.dll.a are not installed.

On MinGW in general, libfoo.dll.a is needed when building an executable which dynamically links against foo library.

A workaround would be to emerge with USE=static-libs, which I suspect is discouraged.


Reproducible: Always

Steps to Reproduce:
1. USE=-static-libs x86_64-w64-mingw32-emerge dev-libs/openssl

Actual Results:  
$ test -e /usr/x86_64-w64-mingw32/usr/lib/libssl.dll.a -a -e /usr/x86_64-w64-mingw32/usr/lib/libcrypto.dll.a; echo $?
1


Expected Results:  
$ test -e /usr/x86_64-w64-mingw32/usr/lib/libssl.dll.a -a -e /usr/x86_64-w64-mingw32/usr/lib/libcrypto.dll.a; echo $?
0

I guess the `rm *.a` used in a lot of ebuilds where the build system doesn't behave isn't the best solution.

    dev-libs/openssl: be more careful when removing static libs
