In particular, for all the libraries being used you'll have to manually provide library dependencies. The particular error suggests that libxml2 depends on zlib, so something like "--with-ld-opt="-static -lz"" should help. Likely there will be other similar errors and you'll have to include other libraries as well. For example, on FreeBSD static linking with libxslt requires "-static -lz -lm -llzma -lmd". Something like pkg-config --static libxslt might be a good starting point for full list of required libraries, assuming libxslt package information is properly installed. Alternatively, ldd on the dynamic library might be a good start. Note well that in general it might not be a good idea to compile things statically unless you have some good reasons to and understand possible consequences. -- Maxim Dounin http://mdounin.ru/ _______________________________________________ nginx mailing list nginx@nginx.org https://mailman.nginx.org/mailman/listinfo/nginx
