Hi,
I need to compile the code twice. Once with -DA and once with -DB
My code look like this:
add_definitions(-DA)
add_library(${mylib_A} SHARED ${myfiles})
remove_definitions(-DA)
add_definitions(-DB)
add_library(${lib_B} SHARED ${myfiles})
remove_definitions(-DB)
What cmake does is to define A and then remove it, so in compile
time, there
is now definition of A or B.
How do I tell cmake that the remove needs to be in compile time?
Regards,
Kfir
You want to create two libraries A and B from the same sourcefiles
${myfiles}. The first one have to be compiled with -DA and the
second one with -DB, haven't it?
So you could simply set the COMPILE_FLAGS property with
add_library(A ${myfiles})
add_library(B ${myfiles})
set_target_properties(A PROPERTIES COMPILE_FLAGS "-DA")
set_target_properties(B PROPERTIES COMPILE_FLAGS "-DB")
Regards,
Andreas
Thanks,
This solved my problems.
Again thanks,
Kfir
Except that COMPILE_FLAGS is the wrong property. You should use
COMPILE_DEFINITIONS without the -D prefix.
Michael
correct me, if I am wrong, but at
http://www.cmake.org/cmake/help/cmake-2-8-docs.html#command:set_target_properties
there is no property "COMPILE_DEFINITIONS".
If I search through the documentation, I get to the target properties.
It seems to me, that COMPILE_DEFINITIONS can set only preprocessor
definitions like -DVAR=VALUE with
set_target_properties(targ PROPERTIES COMPILE_DEFINITIONS "VAR=VALUE").
But if I have a special compiler flag like
-flag:flag_value
I should use
set_target_properties(targ PROPERTIES COMPILE_FLAGS "-flag:flag_value")
?
Andreas
The assignment part is AFAIK optional (probably should be mentioned in
the docs). And yes, to pass special flags, use COMPILE_FLAGS.
COMPILE_DEFINITIONS should be exclusively used for preprocessor-symbols,
as is the command add_definitions().

You are right. The assignment is optional, as said in the documentation.
