Problem with gcc-toolchain modulefile

Problem with gcc-toolchain modulefile

[Reza Housseini]

Hi Guixers

I crated a modulefile with the module command for the gcc-toolchain on a 
foreign system. Unfortunately the LD_LIBRARY_PATH of the gcc-toolchain 
package is interfering with the system (due to the wrong libstdc++.so I 
guess).
Has anyone come across this problem or knows any workaround for it?

Best,
Reza

Hi,

Very late reply… Sorry.  If the question is still unanswered. :-)

Depending on how you created the modulefile, you need to unset
LD_LIBRARY_PATH.  Do you use the package “guix-modules” which creates
Modulefiles using Guix?

I figured a way to do it. I create a new package from the gcc package:

(define-public gcc-standalone
  (package
    (inherit gcc)
    (name "gcc-standalone")))

this allows me to install it as a modulefile.

Yes I am using the guix-modules command, but I have no idea to unset
LD_LIBRARY_PATH in the generated modulefile.

I have no idea if this is the correct way or if I should always use
gcc-toolchain?

Thanks for coming back to this.

Best,
Reza

It’s ’unsetenv’, no?  Well, I am not very familiar with Modulefiles
documentation [1].

Well, the idea of ’gcc-toolchain’ is to provide a complete toolchain
[2], when ’gcc’ provides just one part (compiler).
