That's easy to fix, but ldd will report the same number of library as the cacard library. vscclient_LDADD = libcacard.la $(CACARD_LIBS) $(GTHREAD_LIBS) +vscclient_LDADD = libcacard.la $(GTHREAD_LIBS) > This will require re-making src/Makefile.am to be the real thing, > not the git.mak as it is now. re-making src/Makefile.am? how is this going to help? > Again, it might be possible to use --as-needed here. Debian has some patches to fix that, but really, to save 3 libraries that are not used I don't think it changes much here. > And on a general note, can we avoid nss libs altogether? > For example, qemu now links amost all crypto libs out there, > it uses (directly or indirectly) libssl, gnutls and nss. > From those, nss is only used in libcacard, maybe it is > easy to switch to one of the other implementations? I don't know other pkcs#11 library. But if such patch was proposed, I think it would be acceptable. _______________________________________________ Spice-devel mailing list Spice-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/spice-devel
