[Scons-users] feature request: gcc support for AIX

[Malek,Christophe [CMC]]

Hi Bill,

 

The usual configure, make, make install process seems to do the opposite and tries gcc and only afterwards native compilers. Meaning that if people have both compilers available and mix build tools then they will end up with different compilers when using the different build tools. Such as my case when building Subversion. The apache portable runtime gets built with gcc when using the standard configure, make, install process, but then SCons defaults to xlc when building serf. This causes quite a few problems.

 

Thanks, I will try applying the below patch to the serf SConstruct script.

Chris,

By default SCons will try to first use any native compilers present and then try others.

It sounds like you have both xlc and gcc on your system so you will need to specify the tool list in your Environment() creation.

Environment(tools=['gcc','g++','ar','link'...]

Hi again SCons devs,

Just a small feature request. I am using the latest version 2.3.6.

As you know from my last e-mail, I'm trying to compile Subversion on AIX. I noticed that SCons defaults to the xlc compiler. However, all the other packages for Subversion (Apache portable runtime and Subversion itself) get compiled with gcc by default. This means that when serf tries to link it runs into several undefined functions for things that are usually provided by gcc's libraries:

ld: 0711-317 ERROR: Undefined symbol: .__mcount

ld: 0711-317 ERROR: Undefined symbol: .__udivdi3

ld: 0711-317 ERROR: Undefined symbol: .__moddi3

ld: 0711-317 ERROR: Undefined symbol: .__divdi3

I am of course able to work around this by linking explicitly to -lgcc.

Would it be possible to provide the gcc compiler as an SCons option for AIX?

- Chris
