Description Maarten ter Huurne 2012-01-31 18:55:45 UTC 
User-Agent:       Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/534.34 (KHTML, like Gecko) konqueror/4.7.2 Safari/534.34

The site-config package installs scripts in /etc/profile.d that set the CONFIG_SITE environment variable. The problem with this is that configure scripts will use the site-specific config on any build, including builds that are not intended for the local machine, such as cross compilations. This completely breaks such builds until CONFIG_SITE is undefined.

Please leave it up to the user to define CONFIG_SITE where appropriate and don't do it in /etc/profile.

Reproducible: Always

Steps to Reproduce:
1. install site-config
2. re-login to activate the /etc/profile.d changes
3. install a cross compilation toolchain
4. run some autotools-based package's configure script with the --host=<host-triplet> argument

Actual Results:  
The package's build will break. Typically with a message saying that the compiler cannot produce executables.

Expected Results:  
If CONFIG_SITE is not defined, the cross build works fine.

Example logging from failed configure:

Comment 2 Stanislav Brabec 2012-07-17 17:51:47 UTC 
The heuristic did not work correctly for cross compilation. I fixed this problem in the fix of the but 736143.

If you still see this problem with the new site-config version, please reopen.
