error when compiling sage 5.3

[layla]

Hello,

I am trying to install Sage on my PC. I am using Suse 12.2 (i586). I tried to install sage from the source and got an error message about installing pynac. I am not very good at linux so i did not try much things. I hope that someone can help me. I am copying the error log here:

Is the error reproducible, i.e. does it appear again in the same spot
when running "make" a second time?

If it is, could you attach the file
/home/ogul/sage-5.3/spkg/build/pynac-0.2.4/src/config.log

Hello,

I tried running "make" again and i got the same error. I am attaching the config.log file. Thanks.

Okay, so this is a known issue, but without a proper fix (yet?):
http://trac.sagemath.org/sage_trac/ticket/11391

As a workaround, you can probably build Sage with
SAGE_INSTALL_GCC=yes make

[layla]

That worked. My Sage seems to work now. Thanks a lot :)
