| 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. |
