Hello all,
I have been living in a 32-bit world for apache - but have a request for
a 64-bit version. The first thing I encountered is that apr and apr-util
also need to be in 64-bit mode.
I know that other platforms have their own conventions, rather AIX seems
to have a unique convention with regard to shared libraries.
Currently the make (install) process puts everything in ${prefix}/lib
(in my case ${prefix}=/opt).

total 976
-rw-r--r-- 1 bin bin 9262 Aug 18 11:47 apr.exp
-rw-r--r-- 1 bin bin 455452 Aug 18 11:47 libapr-1.a
-rwxr-xr-x 1 bin bin 932 Aug 18 11:47 libapr-1.la
lrwxrwxrwx 1 bin bin 17 Aug 18 11:48 libapr-1.so -> libapr-1.so.0.5.2
lrwxrwxrwx 1 bin bin 17 Aug 18 11:48 libapr-1.so.0 -> libapr-1.so.0.5.2
-rwxr-xr-x 1 bin bin 509004 Aug 18 11:47 libapr-1.so.0.5.2
drwxr-xr-x 2 bin bin 4096 Aug 18 11:47 pkgconfig
I assume the apr.exp is something for AIX, no comment otherwise
Further, the file libapr-1.a seems to be there. currently. for static
linking support.
Finally, the two links libapr-1.so and libapr-1.so.0 point at the real
shared library: libapr-1.so.0.5.2
What I am going to do manually (to be able to provide dual support in a
single directory) is:
a) add libapr-1.so.0.5.2 to libapr-1.a
b) remove the libapr-1.so* links and file - to prevent confusion (iirc
other systems use two directories $prefix/lib and $prefix/lib64).
While an archive member name may repeat in an AIX archive - as long as
it is a different ABI size - having both 32 and 64-bit in one .a file is
possible - while it is impossible to have the same name twice in, e.g.,
${prefix}/lib
My question:
Will someone assist me with the changes needed to the, I assume, libtool
part that constructs (or processes/reads?) from libapr-1.la. I would
like to think it is a simple change - but I have never really worked
with the autotools and feel like I have 8 left-thumbs when I try an
understand it.
Thanks!
Michael
