Bug #3971

Problem compiling 1.9.2-p0 under AIX 5.3

Added by Glauber Ribeiro over 3 years ago. Updated almost 3 years ago.

Assignee:Yutaka Kanemoto
Target version:1.9.3
ruby -v:ruby 1.8.7 (2008-05-31 patchlevel 0) [powerpc-aix5.3.0.0] Backport:


Compile fails on file cfunc.c, part of the dl extension, with many errors similar to the following:

"cfunc.c", line 378.13: 1506-033 (S) Function is not valid. Function cannot return a function.
"cfunc.c", line 378.13: 1506-963 (W) The attribute "cdecl" is not a valid variable attribute and is ignored.
"cfunc.c", line 378.13: 1506-117 (S) Operand must be a scalar type.

This is the only file that fails. If i delete the dl extension, the build succeeds.

This is AIX 4.3 with IBM XL C for AIX v 10.1 in "cc" mode (64-bit).

I'm attaching a text file which has the output of "./configure --prefix=/aissrc/inc/ruby19 && make".

Ruby 1.9.1-p430 compiled correctly.

Sorry to late to respond.
Could you please try warnflags option for configure like this?
"./configure --prefix=/aissrc/inc/ruby19 warnflags=-qinfo=por && make".

You may see many information messages, but it might be harmless.
I would like to know whether you can compile dl module by using warnflags.

Ruby 1.9.1-p430 compiled correctly.
In my test env, I can see the same problem on both 1.9.2p0 and 1.9.1p430.
