Minor Description
The output from pkg-config does not properly indicate the full dependency requirements for static linking. For example, if configured --with-openssl=... then the pkg-config --static output should reflect this.
Here's an example from libcurl demonstrating this:
curl-7.21.6 $ ./configure
curl-7.21.6 $ cp libcurl.pc libcurl-plain.pc
curl-7.21.6 $ ./configure --with-ssl
curl-7.21.6 $ diff libcurl-plain.pc libcurl.pc
38c38
< Libs.private: -lrt
—
> Libs.private: -lssl -lcrypto -lrt -lssl -lcrypto -ldl
curl-7.21.6 $ pkg-config --libs libcurl
-lcurl
curl-7.21.6 $ pkg-config --libs --static libcurl
-lcurl -lssh2 -lssl -lcrypto -lrt -lz
curl-7.21.6 $
This can be (crudely) fixed by adding the following to activemq-cpp.pc.in:
Libs.private = @AMQ_LIBS@
[A cleaner solution would require updates of configure.ac for a more precise specification.]
