Hello everyone. I noticed that my libgnutls-devel package doesn't depend on libtasn1-devel one. Looks like this is due to that line in .pc file: Libs.private: -L/usr/lib -lgnutls -ltasn1 -lgcrypt -lgpg-error Shouldnt it be Libs: -L${libdir} @LIBGNUTLS_LIBS@ instead? Without libtasn1-devel installed, macro AM_PATH_LIBGNUTLS doesnt work.
