Cross platform development with gnustep make

[Andreas Höschler]

Hi all,

after migrating from MacOSX 10.2 to MacOSX 10.5 I get a bunch of the  
following warnings (due to the newer gcc) when building frameworks  
with gnustep make.

i686-apple-darwin9-gcc-4.0.1: -framework: linker input file unused  
because linking not done
i686-apple-darwin9-gcc-4.0.1: AppKit: linker input file unused because

gcc --v

Using built-in specs.

Thread model: posix
gcc version 4.0.1 (Apple Inc. build 5465)

The resulting frameworks are usuable and link fine with tools and  
applications. This output is just annoying and makes it hard to  
extract useful info (warnings and errors) from the gcc output. Any  
idea how this can be prevented.  My GNUmakefile looks as follows:

...
LIBRARY_NAME = libSRInterface
VERSION = 1.0.0
ADDITIONAL_OBJCFLAGS += -Wno-parentheses -Wno-import
ADDITIONAL_INCLUDE_DIRS +=  -framework AppKit  -framework  
SRAppKit             -framework SRDesign -framework  
SREnterprise             -framework SRFoundation -framework SRObjects
SRInterface_FRAMEWORK_LIBS +=  -framework AppKit  -framework  
SRAppKit             -framework SRDesign -framework  
SREnterprise             -framework SRFoundation -framework SRObjects
LIBRARIES_DEPEND_UPON += -framework AppKit  -framework  
SRAppKit             -framework SRDesign -framework  
SREnterprise             -framework SRFoundation -framework SRObjects
SRInterface_RESOURCE_FILES = MultipleObjects.tiff DocumentIcon.tiff  
SingleObject.tiff
...

Thanks a lot,
