The shell script options-ibverbs-static.sh was used with make in forcing static linkage of ibverbs libraries. When choosing to link with a static dependency in meson, the generated .pc file will not force such static linkage. The solution will rely on using this script in meson. If linking with libraries installed in a non-standard path, an option -L is provided via EXTRA_LDFLAGS in case of using make. With meson, tuning PKG_CONFIG_PATH for pkg-config should be enough. When statically linking an application, the .pc file must save the -L path so the application link will work without any extra option. That's why --libs-only-l is replaced with --libs which includes -L. Options which are neither -l or -L are filtered out because not needed and can cause compilation issues with the legacy system using make. The other change in this script is to drop the first occurrences of the main library file (libiverbs.a). Only the last occurrence is kept. It fixes some undefined references when linking a static application using libdpdk.pc. Signed-off-by: Thomas Monjalon <thomas@monjalon.net> Acked-by: Bruce Richardson <bruce.richardson@intel.com>
