Hi, The .pc file doesn't work well because it's hard-coded to one crypto engine. Would it be possible to generate a .pc file for each crypto engine (xmlsec1-openssl.pc, xmlsec1-gnutls.pc, etc.)? Also, the cflags in the .pc file need some work: XMLSEC_NO_XKMS is defined twice, and I don't think the -g and -O2 options should be there. Regards, -John -- http:// if l .o /
