- Subject: [PATCH] c++ binding missed when cross compiling
- Date: Mon, 16 Feb 2015 01:01:48 -0500
- The configure script hard codes the include dir to the prefix'ed include dir,
- when checking if c++ compiler works. This breaks the compiler's built-in search
- path. I've included two patches. The first works on the configure.in file, which
- requires your autoconf stuff to test and I'm not ready to meddle with at the
- moment. The other works directly on the configure file. I've tested the second
- one; it should mirror what the first patch tries to achieve and works for me.
