Hi,
I'm using GCC as a pre-processor for a C-like language (EDDL) to handle all
the includes, macros, etc. producing a single source file for another compiler.
I have a problem where if I call GCC from my python script some of the
#defines are not processed in the output. However if I paste the exact same
command into a shell, I get a correct output.
I'm calling GCC in this manner:
/usr/bin/gcc -I /tmp/dd-compile_1286930109.99 -I /home/foo/eddl-includes
-D__TOKVER__=600 -ansi -nostdinc -v -x c -E -o
/tmp/dd-compile_1286930109.99/11130201.ddl.OUT
/tmp/dd-compile_1286930109.99/11130201.ddl
I'm not really sure how to debug this. I already checked the ulimits, and
permissions shouldn't be a problem since it's all run by the same user.
GCC produces no warnings, or errors. The output is mostly OK, other macros
have been processed.
If I diff the working output with the non-working one, the differences are
only these bunch of skipped #defines.
gcc version 4.4.5 (Ubuntu/Linaro 4.4.4-14ubuntu5)
Linux 2.6.35-22-generic #34-Ubuntu SMP Sun Oct 10 09:26:05 UTC 2010 x86_64
GNU/Linux
Any suggestions for helping me debug this would be much appreciated.
thanks,
