Invoke configure +--without-ssl --with-nss. + +The source code in lib/nss.c currently cause a compiler warning due to the +lack of a prototype. The prototype is provided by the public header provided +by NSS called "base64.h". But since we use a private header in libcurl named +identically, we cannot include the NSS one. + +This problem persists because: + +* NSS doesn't use a properly established separate subdir for their include + files. Instead different distros have put them in /usr/include/nss and + /usr/include/nss3 etc. + +* The pkg-config output for NSS provides a full -I path to the nss include dir, + so we cannot #include <nss/base64.h> or <nss3/base64.h>. This too may be due + to how distros do it. + +* I tried getting the (all new in June 2008) NSS 3.12 tarball to check how it + behaves out-of-box but this wouldn't even build - complaining on missing + files that aren't included in the tarball. The tarball doesn't even include + build instuctions but you must hunt them down on their web site. + +Due to these design problems we may of course get further similar problems in +the future, but I hope we can work them out somehow along the way. -- GitLab
