ALICE O2 build fails on CC7 with python 2.7.10 error (freetype)

[Barthelemy]

To be noted that it seems to be a problem with pkgconfig although I see the proper config :

[bvonhall@aidrefflp01 alice]$ more /usr/lib64/pkgconfig/freetype2.pc
prefix=/usr
exec_prefix=/usr
libdir=/usr/lib64
includedir=/usr/include

Name: FreeType 2
Description: A free, high-quality, and portable font engine.
Version: 16.0.10
Requires:
Libs: -L${libdir} -lfreetype
Libs.private:
Cflags: -I${includedir}/freetype2 -I${includedir}

Regarding the pig-config part, I will check. We had some fix in the past, but maybe it does not work for slc6.

Regarding the second question. Can you run:

alibuild/aliDoctor | grep -i python

and tell me what it says? I suspect you are missing the certifi module. As noted in #265 we should allow to pickup python from the system and only rebuild the modules it lacks.

Please notice that this is a CC7 setup, not SLC6.
Here's the output:

Indeed you are lacking matplotlib numpy and certifi . Will try to adapt the recipe so that only the python modules get rebuilt.

[Barthelemy]

I think that I have the same error on SLC6. You can test it here :
eulisse@pcald02a:/alice

./alibuild/aliBuild build o2 --disable GEANT4,GEANT3,GEANT_VMC

[ktf]

I think I've fixed this as part of #305. I managed to compile successfully on pcald02a. Now testing everywhere and then I will merge it.

[Barthelemy]

cool

Closing as duplicate of #305.
