 Bug Type:         Compile Failure
 Operating System: AIX 5.2
 PHP Version:      5.1.6
 New Comment:

Sorry to insist but I wanted to make it clear because I reference it in
my (excellent :-) document about building PHP on AIX
(http://www.tekwire.net/joomla/content/view/16/1/), and several people
asked about this bug's status.

While I generally agree with your decision of restricting the build
environment you support, I must say that it is not the case for GNU ld.
It is perfectly legitmate not to support native compilers but linkers
are a more sensitive case and attempting to use only the GNU linker on
systems like AIX or HP-UX has a number of side effects impossible to
solve for non-expert people. Building Apache & PHP on these systems is
already complex (especially PHP 4) and it is not worth the pain to add
another difficulty to the task. For people used to their OS, using gcc
is not a problem, but using the GNU linker is not natural and the
switch is much less transparent.

And there is still this message when compiling LDAP saying that it
refuses to generate dynamic libs because GNU ld is supposed not to
generate them properly on AIX. Do you consider it as a wrong assertion
in LDAP's configure ? What's your advice about this ?

Sorry, we do not support AIX native linker.

Sorry but, after fighting with GNU ld and gcc during 2 hours, I am
giving up. Using GNU ld brings some new errors in the configure stage.
I solved one by adding '-Wl,-rpath,/usr/lib' to LDFLAGS but, now, it is
failing LDAP detection and I won't spend the night on it. Another reason
why I am giving up is that ldap's configure refuses to generate dynamic
libraries with GNU ld (saying that GNU ld is known not to generate
correct dynamic libs on AIX). So, as I want to generate everything with
the same linker, I will keep the AIX linker.

But I think I know why we have unresolved references when loading gd.
As you said, the PHP core is linked with GNU ld but, on AIX, if the
linker does not detect any reference to a library, it does not keep it
in the list of required libraries. In my configuration, as I have kept
the core to the minimum, I don't have any reference from the core to
libm and, when I run 'ldd' or 'dump -H' against 'php' or 'libphp5.so',
the libm is not referenced.

As, by default, gd is not linked with the libm, it does not have the
reference and, finally, when it is loaded, the libm symbols cannot be
resolved as this lib is not referenced anywhere in the installed
files.

That's why, as every other extension is linked against the libs it
needs, I still think that gd should be linked explicitely with the
libm.

OK. I was using GNU make but not GNU ld. I am going to try it.
