Building lame 3.92 on SCO OpenServer 5.0.6a with gcc 3.2, I encountered
the following problems:
- If the configure script detects gcc, it stores the output of "gcc
--version" in the variable $GCC_version. It then uses this variable
to determine optimization flags. gcc 3.2, in addition to the gcc version
number, outputs a copywrite notice. Consequently, the test for the
value of $GCC_version can never match. Other gcc versions may behave
similarly. This issue is not specific to SCO OpenServer.
- The configure script assumes that gnu ld is being used if gcc is
detected and adds -pipe to CFLAGS. On SCO OpenServer, the native ld
is used with gcc and does not understand -pipe.
Here is a patch which addresses these issues. Would using a current
version of autoconfig to generate configure also fix them?
