| Subject: [PATCH 1/1] configure: fix test-for-synth check with GCC 4.9.0 |
| |
| With GCC 4.9.0 oprofile 0.9.9 build fails on non-PPC platfroms because |
| the "test-for-synth" configure check result is incorrect: There is a NULL |
| pointer dereference in the test program, so the compiler seems to optimize |
| the rest of the code away, and the test will always succeed regardless |
| whether powerpc_elf64_vec/bfd_elf64_powerpc_vec are present or not. |
| Fix by allocating the referred struct statically. |
| |
| While at it, also include stdio.h to avoid a compiler warning. |
| |
| [Romain: backport the patch to 0.9.9] |
