[gdal-dev] GDAL python bindings build error (gcc command replaced by bash)

[Kai Muehlbauer]

Hi James,

I did experience the same issue. See

https://lists.osgeo.org/pipermail/gdal-dev/2016-July/044678.html

Although I did not find the root cause of this, I found that in my use 
case, copying and unsetting CC and CXX environment variables did the trick.

So what I did is:

export CF_CC=$CC
export CF_CXX=$CXX
unset CC CXX
./configure CC=$CF_CC \
             CXX=$CF_CXX \
             --prefix=$PREFIX
make

Hoping for more insight by gdal-devs.

Cheers,
Kai
