[CMake] Xcode generator problems

[Axel Roebel]

Hi,

I just tried to generate Xcode project files for some of my
cmake supported sources. I encountered three problems:

1)  I tried to communicate -framework Carbon flags
to the link stage. I tried 

SET(LINK_FRAMEWORKS "-framework Accelerate -framework Carbon")

   SET(CMAKE_SHARED_LINKER_FLAGS_RELEASE "${CMAKE_SHARED_LINKER_FLAGS_RELEASE} 
${LINK_FRAMEWORKS} " CACHE STRING "Linker flags " FORCE)
  SET(CMAKE_SHARED_LINKER_FLAGS_RELEASE "${CMAKE_SHARED_LINKER_FLAGS_RELEASE} 
${LINK_FRAMEWORKS} " CACHE STRING "Linker flags " FORCE)
 
as well as

 SET_TARGET_PROPERTIES(svpmain${DEBUGEXT} PROPERTIES LINKER_LANGUAGE CXX 
OUTPUT_NAME svp  LINK_FLAGS ${LINK_FRAMEWORKS})

In both cases the generated project does not use the framework flags I asked 
for. The unix makefile generator, however, works properly. Maybe there is a 
reason or another mechanism that should be used?

The second problem is more annoying:

From time to time the compiler fails completely and the error.log shows the 
error message:
...
   setenv VERSION_INFO_STRING "\"@(#)PROGRAM:XCODE_DEPEND_HELPER  PROJECT:CMAK
E_TRY_COMPILE-  DEVELOPER:roebel  BUILT:\" __DATE__  \" \" __TIME__ \"\""
    setenv WARNING_CFLAGS "-Wmost -Wno-four-char-constants 
-Wno-unknown-pragmas
"
    setenv XCODE_APP_SUPPORT_DIR "/Library/Application Support/Apple/Developer
Tools"
    setenv YACC /usr/bin/yacc
    /bin/sh 
-c /Users/roebel/tmp/svp_basic_transformer/build/CMakeTmp/./CMAKE_T
RY_COMPILE.build/Debug/XCODE_DEPEND_HELPER.build/Script-68598068598068598000000
0.sh
/bin/sh: /Users/roebel/tmp/svp_basic_transformer/build/CMakeTmp/./CMAKE_TRY_COM
PILE.build/Debug/XCODE_DEPEND_HELPER.build/Script-685980685980685980000000.sh:
/bin/sh: bad interpreter: Text file busy
** BUILD FAILED **

All configuration tests therefore have more or less random values, because 
they fail either due to the fact that the tested condition is false or because 
the compiler fails completely. The systems I am working with are dual 
processor machines and I suppose that has something to do with these errors. 
cmake is version 2.2.3. Are there any known solutions?

The third  problem is probably my missing understanding.  I wanted to 
overwrite the configuration types, however,
SET(CMAKE_CONFIGURATION_TYPES "Release;Debug" CACHE STRING "Configuration 
types" FORCE)

did not change the value of CMAKE_CONFIGURATION_TYPES .
Is this variable read only?

Cheers,
