Pari fails to build on AIX #9990

Closed bac7d3ea-3f1b-4826-8464-f0b53d5e12d2 closed 6 years ago

The Pari svn snapshot 12577 is failing to build properly on AIX. If the Pari developers would like access to AIX hardware (I don't think they have it), then I can provide access to my personal RS/6000

Reported upstream: http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1102

The extension .so doesn't seem to be the problem, since apparently the loader recognizes it as a shared library.

The extension .a for shared libraries is of course a bit odd since PARI also builds a static version which typically has the same name ending with .a...

I wonder what the logic is for having both shared and static? I'd rather use the right extension on the right platform. I can discuss this with the Pari developers after getting clarification from some AIX experts on comp.unix.aix - they are a very helpful bunch.

For an executable that doesn't make that much sense, but gp-sta[tic] is tested against gp-dyn[amic], which isn't bad.

And since PARI is (also) a library, it's pretty normal to build both. (Every proper library does this, at least if you --enable-shared and --enable-static, depending on what the defaults are.)

I've reported this upstream:

Bug#1102: Acknowledgement (Build failure on AIX 5.3 - shared object has no .loader section)

The bug reported included a log against the latest snapshot, which shows the same problem.

I got this from Bill Allombert, a Pari developer:

Could you try to deactivate shared libraries by using
./Configure --static

That solves the problem - Pari then installs ok. I will create a patch.

Did you only try to compile PARI/GP stand-alone, or also within Sage? Because I don't know whether it is possible to compile Sage statically.

Only outside of Sage at this point. Some of the ATLAS libraries are only stati, but Sage links to them ok. Since Sage will not build fully on AIX, it's hard to know for sure what problems might present themselves at a later date, but I doubt a static Pari library would be one of them.

I later found out that it appears that on AIX the .a files are archives which can contain both static and shared objects. But using .so as an extension for shared objects is not a problem in itself.

No problem. This should be a very low-risk patch, as it will be specific to AIX. But I have some other more important things to do now, so it will have to wait.

"No feedback yet." is totally not correct here. Most applicable would be "Developers sort-of acknowledge the bug but don't really care enough to fix it"

I believe "-Wl,-r" is incorrect, "-Wl,-brtl" may have to be added for the linking to happen, as in the linking of binary.

The warning is about the fact that bcopy is in both libreadline and libc. Probably because I have both libreadline.a and .so at the moment and .a would have chosen over .so. That's minor compared to some other stuff like the fact that it segfault:

For info that's on a power7 machine running aix-6.1(TL6) with gcc-4.6.3 [compiled on another LPAR on the same machine running TL7].
