The issue here is that environment setup file for the 32 bit GCC refers to a GCC which does not exist (or it exists, but under a different name). Additionally, the problem seems to be still there for 2.2 master. 65507 5 sgw 2016-08-25 14:57:11 +0000 Really a duplicate of 10054 *** This bug has been marked as a duplicate of bug 10054 *** 66008 6 jose.perez.carranza 2016-09-09 16:04:55 +0000 verified duplicate
