Bug 522754 – dev-python/pycairo-1.10.0-r4 uses the same build environment that was used to emerge dev-lang/python

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description Abulhair Saparov 2014-09-14 00:10:27 UTC]

My system recently became unable to emerge dev-python/pycairo-1.10.0-r4 (I think because the 2.6 python target was recently removed). It fails at the configure step. Looking into the configure log, I found that it uses distutils.sysconfig.get_config_var to query the build environment. I'm not sure, but I think this is incorrect, as this will return the build environment used to build dev-lang/python, and not the current build environment. In my case, since I built dev-lang/python with icc, and pycairo is being emerged with gcc, an option in CFLAGS is not recognized by gcc, resulting in the failure.




Reproducible: Always

Steps to Reproduce:
1. Compile python using an initial build environment (CC, CFLAGS, etc). In my case, I have python 2.7 and 3.3 compiled using icc (similar to http://www.gentoo-wiki.info/HOWTO_ICC_and_Portage).
2. Modify the build environment, for example by changing CC or adding options to CFLAGS.
3. Emerge pycairo.
Actual Results:  
When emerging pycairo, portage will configure them with some odd combination of the old and new environment (options from both the old and new CFLAGS are used). In my case, dev-lang/python was configured with the CFLAG -fno-stack-protector-all, but the python library I want to emerge is set to use gcc. Since gcc does not recognize this option (it has fno-stack-protector), the configure step fails.

Expected Results:  
pycairo should be configured using only the current build environment, without using the old CFLAGS used to build dev-lang/python.
