-D switch is expanded incorrectly
« on: October 18, 2010, 03:10:30 pm »
In CodeBlocks C++ project, settings, compiler, #define, I added these options:
Code: [Select]
_DEBUG
DATA_DIR=\"/media/Shared/SiX/Data\"
This produces the following command line:
Code: [Select]
g++ -Wall  -g -fPIC -save-temps -D_DEBUG -DDATA_DIR=\"/media/Shared/SiX/Data\"    -I../Includes  -c /media/Shared/SiX/SiXConfiguration/PathManager.cpp -o obj/Debug/PathManager.o
When I open precompiler output, I see that source code line with DATA_DIR constant is expanded incorrectly. Source line:
Code: [Select]
commonDataDir = DATA_DIR;
is expanded as:
Code: [Select]
commonDataDir = /media/Shared/SiX/Data;
Should be:
Code: [Select]
commonDataDir = "/media/Shared/SiX/Data";
The same settings in the Eclipse CDT produce correct result. How can I fix this?

See what is the real command executed by Eclipse's CDT, then you'll know what to enter in the defines field.
I would try to replace \" with ".
Also reading the gcc docs about this expansion will help you a lot.

By the way this is not a C::B problem, but a configuration problem...

Thanks. Eclipse CDT produces command line with the same parameter: -DDATA_DIR=\"/media/Shared/SiX/Data\". Anyway, I solved the problem by changing the source code, as was suggested in another forum:
