SCons always uses relative path even when absolute path is set with LIBPATH

[msbm97]

I am compiling a complex project with multiple shared library which will be linked to a code not using scons so I need the registered paths to be absolute. My sconscript has the following code

common_build_dir = os.getcwd() + os.sep+ 'build' +os.sep() + 'common'

dynamic_lib = env.SharedLibrary(target = 'dynamic_lib',
source = [srcs],
LIBS = 'common',
LIBPATH= common_build_dir,
RPATH = common_build_dir
)

When I run otool the output is:
./lib/libTdynamic_lib.dylib:
build/dynamic_lib/libdynamic_lib.dylib (compatibility version 0.0.0, current version 0.0.0)
build/common/libcommon.dylib (compatibility version 0.0.0, current version 0.0.0)

and I can see from the build commands that scons is indeed omitting the complete path and only referencing from relative to wheres construct is defined.

PS: I tried joins the scons mailing list but have not received an approval email

which version of SCons, python, platform?
Also can you paste the relevant part of your build log?

[bdbaddog]

check your spam folder for approval email.

MacOS ?

[msbm97]

yes that is correct. I am sorry I missed where you were requesting the platform also.

[bdbaddog]

o.k. Yes. This is expected behavior. SCons will always normalize string paths to relative.
You might try Dir(your path) instead of the string and see if that makes any difference.

[bdbaddog]

Please try signing up for users mailing list again..

[msbm97]

I tried what you suggested and made the following change to my script

newBuildDir = DIR(common_build_dir)

dynamic_lib = env.SharedLibrary(target = 'dynamic_lib',
source = srcs,
LIBS = 'common',
LIBPATH= newBuildDir,
RPATH = newBuildDir

Unfortunately, it didn't seem to make any difference the output of otool -L dynamic_lib.dylib still showed the relative path.

Is there anything else I can do to get scons register the absolute path? It will be a pain if the files always register relative paths because I have 7 projects which have varying levels of dependency on each other.

I got the confirmation email and I am now in the scons user groups.

[bdbaddog]

please.

I'm going to close this issue as it seems the real issue was getting RPATH to work?
