Preprocessing on the sources file of device driver

NTDEV

C_DEFINES=$(C_DEFINES) -D_PRODUCT_A
//C_DEFINES=$(C_DEFINES) -D_PRODUCT_B

#ifdef PRODUCT_A // <- I want to do doing like this in a sources file.
MOST_SOURCES= a.c b.c productA.c
#elif PRODUCT_B
MOST_SOURCES= a.c b.c productB.c
#endif

Is there a proper syntax?

We’ve covered this lots of times here. Here’s one from a few months ago:

Tim Roberts’ first reply explains the problem.

MOST_SOURCES= a.c b.c productA.c
#elif PRODUCT_B
MOST_SOURCES= a.c b.c productB.c
#endif

productAB.C:

#ifdef PRODUCT_A
#include “productA.c”
#else
#include “productB.c”
#endif

No, nmake syntax is !if. However you cannot conditionally define your SOURCES line, so this line of approach will not work in the end. Two tools process the sources file during the build process; nmake.exe and build.exe. Build.exe doesn’t support conditionals in the way nmake does.

I’ve used a way Tim Roberts said.

Thanks everyone!
