[PATCH v2] sb: Add support to search for a suitable version of python.

[Malte Münch]

Hi,

i think you meant that command here:

/home/mamu/dr/rsb/source-builder/sb/rtems-build-dep -c gcc  -H
python2.7/Python.h

with an additional -d flag it returns:


+ '[' -z header ']'
+ '[' -z gcc ']'
+ '[' -z python2.7/Python.h ']'
+ '[' header = header ']'
++ echo
++ gcc -xc -E -v -
++ awk 'BEGIN {flag=0;} /starts here/{flag=1;next}/End/{flag=0}flag'
+ inc_paths=
+ echo not-found
not-found
+ exit 0

The python header is located under /usr/include:

[mamu at verstappen rtems]$ find / -name 'Python.h' 2> /dev/null
/usr/include/python2.7/Python.h
/usr/include/python3.7m/Python.h

Best,

Malte
