Re: [CMake] how to detect architecture ?

2018-01-20 Thread Franck Houssen

Got it, thanks.
I'll do that even if Windows is not an OS I target (I guess tests will not run 
on Windows - run bash script like ./test.sh in which I redirect outputs with > 
and other stuffs the unix way).

Note that Windows DLLs may also happen to have to lib prefix (e.g. CMake adds 
them
by default when building projects with MinGW).

Re: [CMake] how to detect architecture ?

2018-01-19 Thread Chuck Atkins

Hi Franck,

I'd suggest going a little more robust by using both
CMAKE_SHARED_LIBRARY_PREFIX and CMAKE_SHARED_LIBRARY_SUFFIX to generate a
function at configure time to resolve the correct filename.

For example, util.h.in:

#ifndef _UTIL_H_
#define _UTIL_H_

#include 

static inline
void get_library_filename(char* filename, const char* libname)
{
  sprintf(filename, "@CMAKE_SHARED_LIBRARY_PREFIX@
%s@CMAKE_SHARED_LIBRARY_SUFFIX@", libname);
}

#endif /* _UTIL_H_ */


Then your CMakeLists.txt:

configure_file(
  ${CMAKE_CURRENT_SOURCE_DIR}/util.h.in
  ${CMAKE_CURRENT_BINARY_DIR}/util.h
  @ONLY
)
add_executable(foo main.c ${CMAKE_CURRENT_BINARY_DIR}/util.h)
target_include_directories(foo PRIVATE ${CMAKE_CURRENT_BINARY_DIR})

And finally main.c:

#include 
#include 

int main(int argc, char **argv)
{
  char filename[256];

  get_library_filename(filename, "foo");

  printf("Library foo uses file %s\n", filename);

  return 0;
}

This will give you "libfoo.so" on Linux, "libfoo.dylib" on Apple, and "
foo.dll" on Windows.

if( APPLE )
   install( PROGRAMS apple.script.sh DESTINATION script.sh )
elseif( UNIX )
   install( PROGRAMS linux.script.sh DESTINATION script.sh )
endif( )
# not sure what the correct tag in endif should be.

so you can just keep 2 scripts and install approrpiately

[CMake] how to detect architecture ?

2018-01-09 Thread Franck Houssen

Is there a way to detect architecture ? 

Seems there is nothing simple since these old threads : 
https://stackoverflow.com/questions/11944060/how-to-detect-target-architecture-using-cmake/12024211#12024211
 
https://stackoverflow.com/questions/16796629/cmake-create-architecture-aware-makefile
 

Is there a solution now ? 

My need is quite simple: I have an executable who needs dlopen. To test it, I 
planned to write a bash script that would have done "./exe /path/to/lib. so " 
on linux (debian, ...) OR "./exe /path/to/lib. dylib " on osx. To replace 
correctly so/dylib in the bash script I need to know the architecture. Any idea 
how to do this ?
