Hi,
I also got this error because of gcc 4.4. If this is your case, try to edit
your SConstruct file, and change
48 if os.environ.get('GCC_VERSION') == '44':
49 GCC_EXTRA_CCFLAGS = ['-fno-tree-vrp']
50 GCC_DTOA_EXTRA_CCFLAGS = ['-fno-strict-aliasing']
51 else:
to
48 if os.environ.get('GCC_VERSION') == '44':
49 GCC_EXTRA_CCFLAGS = ['-fno-tree-vrp', '-fno-strict-aliasing']
50 GCC_DTOA_EXTRA_CCFLAGS = ['-fno-strict-aliasing']
51 else:
Also check your environment variable GCC_VERSION. export GCC_VERSION=44 if
does not exist or is wrong.
I hope this works for you! :)
