[Scons-users] Compiling a program with scons

[Owen Alanzo Hogarth]

Hi Bill

That helped but then it seems like I didn't quite need that Configure
object just yet. I added lib/ include directories so now my SConstruct file
looks like this:
env = Environment(
LIBPATH=['/Users/blubee/Downloads/curl-7.40.0/lib/'],
CPPPATH=['/Users/blubee/Downloads/curl-7.40.0/include/curl'])

env.Program(target = "curl", source = [Glob("*.c")])


I get this error:

scons: done reading SConscript files.

scons: Building targets ...

gcc -o tool_binmode.o -c -I/Users/blubee/Downloads/curl-7.40.0/include/curl
tool_binmode.c

In file included from tool_binmode.c:22:

./tool_setup.h:36:10: fatal error: 'curl_setup.h' file not found

#include "curl_setup.h" /* from the lib directory */

         ^

1 error generated.

scons: *** [tool_binmode.o] Error 1

scons: building terminated because of errors.


Now that file curl_setup.h is actually already in the lib directory located
under the LIBPATH variable.


What am I missing here?
