[Vortex] libaxl compilation errors on AIX64

[Satish Mittal]

Hi All,

When trying to compile libaxl on AIX64 platform, I ran into couple of
issues.

1) The ./autogen.sh script always needs python, even though I didn't want
it. I had to install python to workaround it. This is discussed in a
separate thread.
2) After running ./configure; I ran make. I got the following error:

libaxl% make

On analysis, I figured out that the *configure.ac* script had the following
flags hardcoded:
CPPFLAGS="*-Wall -Werror* $PYTHON_INCLUDES"

The* -Wall* and* -Werror* compiler flags are not recognized by AIX compiler.
Hence I replaced it with the following flag for AIX64:
CPPFLAGS="-q64 -qwarn64 $PYTHON_INCLUDES"

3) After making the above change, I proceeded with the compilation. This
time it failed with the following error:
make[2]: Entering directory
`/home/devbld/glal/smittal/smittal_cpp_jsf_unix/thirdparty/AIX-ppc64/libaxl/src'

It meant that -Wall flag was still hardcoded somewhere else. On analyzing, I
found that the *Makefile.am* scripts have it hardcoded inside them. I fixed
them to remove -Wall entries.

4) After fixing Makefile.am files, I again hit similar compilation error,
but this time for *-**Wstrict-prototypes* flag. Hence I had to remove that
flag as well from all Makefile.am files. After making those change,
compilation succeeded for me.

Here is a summary of various Makefile.am files and various options within
them (which I had to remove):

./babel/Makefile.am: -Wall, -ansi

./knife/Makefile.am: -Wall

./ns/Makefile.am:  -Wall, -ansi

./src/Makefile.am:  -Wall, -ansi, -Wstrict-prototypes

./test/Makefile.am: -Wall

./py-axl/Makefile.am:  -Wall, -ansi, -Wstrict-prototypes
It seems that the configure.ac and Makefile.am present within axl are still
having options specific to Linux platform.

Satish M
