Pipe `stderr` when calling `subprocess.Popen` #52

Closed praetorian20 closed 8 years ago

praetorian20 commented 8 years ago

Code that uses the which command to find castxml and clang++ now pipes stderr in addition to stdout. This prevents error messages from being printed if the executables being searched for are not on PATH.

What errors have you seen ?

I could not reproduce what you are describing here. I removed castxml from my path (and I have no gccxml installed). which castxml returns command not found, but I do not get any supplementary errors while running pygccxml (only the exception "No c++ parser found. Please install castxml or gccxml."). I'll have a try on Linux to see if there is a difference.

I am OK on the principle of the patch, just want to know more in which cases this is happening.

Just the standard stuff that which prints when it cannot find the executable

which castxml
/usr/bin/which: no castxml in (<path>)

It's a cosmetic fix, doesn't affect any functionality.

I don't have castxml on path, instead I specify it using xml_generator_path in _xmlgenerator.cfg.
