Bug 313173 – www-apache/mod_wsgi-3.2 fails to build due to bad CFLAG quoting through apxs

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Mark A Rada 2010-04-05 03:36:47 UTC]

When I try to build mod_wsgi on my system it crashes very early in the build due to apxs not understanding the CFLAGS which get passed to it.

The relevant dump from the ebuild:

Reproducible: Always

Steps to Reproduce:
1. Have some CFLAGS set (i.e. -march=k8)
2. Try to emerge mod_wsgi


Actual Results:  
Fails to build

Expected Results:

It works fine, here:

/usr/sbin/apxs2 -c -I/usr/include/python2.6 -DNDEBUG  -Wc,-march=native -Wc,-O2 -Wc,-pipe  mod_wsgi.c -Wl,-O1 -L/usr/lib64 -L/usr/lib64/python2.6/config  -lpython2.6 -lpthread -ldl -lutil -lm

[Comment 4 Arfrever Frehtes Taifersar Arahesis (RETIRED) 2010-07-02 22:48:26 UTC]

Does this problem occur with www-apache/mod_wsgi-3.1?

[Comment 5 Chí-Thanh Christopher Nguyễn 2010-07-07 22:24:01 UTC]

The issue might be related to C preprocessor flags, from comment #2:
CPPFLAGS="-march=k8 -msse3 -O2 -pipe"

No further info, closing.
