Subject: configure: --with-libXXX-prefix does not work

configure: --with-libXXX-prefix does not work

I am unable to build libssh2 on an AIX 5.3 host. OpenSSH is not installed
on this machine but was built successfully in a separate directory so I
used configure's --with-libssl-prefix.

I have experimented with the stable libssh2-1.4.3 and with the latest
snapshot (libssh2-1.4.4-20140106) with the same results.

This is what happens:

faxplus_at_ichh2s89 /home/faxplus/libssh2/libssh2-1.4.4-20140106-AIXP64
>./configure --with-openssl
--with-libssl-prefix=~/OpenSSL/openssl-1.0.1e-AIXP64 --with-libz

errors out with the following:

The OpenSSL files are all there (I have set a symlink named 'lib' to point
to OpenSSL's base directory where the shared libs are):

Please note that I have the impression that the same problem exists with
the --with-libz-prefix so I suspect all --with-libXXX-prefix options are

I have tried to build libssh2 on a Linux/x64 machine with an installed
libssl but regardless of the --with-libssl-prefix settings configure
always picks up libssl from /usr/lib. The same applies to the
--with-libz-prefix as well. I have verified this with ldd on the libss2.so

I have tried hard to dig into the configure logic but was unable to find
out how it works. Maybe some configure expert can have a look into this?

I'm happy to try any fix.

Thanks and best regards,
- Michael
