[CMake] CMake still broken post-2.8.1

[Phil Smith]

Ah, ok. With 2.8.1:

C:/Program Files/Regina/regina.exe cc.rex dcc.exe   CMakeCCompilerId.c

With 2.8.6:
C:/Program Files/Regina/regina.exe cc.rex;dcc.exe   CMakeCCompilerId.c

Note the semicolon; where'd it come from? It's not in the toolchain file:
----------------------------------------
# This is a CMake Toolchain file, required for cross-compiling using
# the Dignus cross-compilers on Windows, compiling for z/OS.

# Tell CMAKE the target system name
SET(CMAKE_SYSTEM_NAME "IBM_ZOS")

# Specify the cross-compilers
SET(CMAKE_C_COMPILER   "regina.exe" "cc.rex dcc.exe")
SET(CMAKE_CXX_COMPILER "regina.exe" "cc.rex dcxx.exe")

SET(CMAKE_C_CREATE_STATIC_LIBRARY "DAR -rv <TARGET> <OBJECTS>")

SET(CMAKE_CXX_LINK_EXECUTABLE "plink.exe \"-S$ENV{DIGNUS_PROGRAM}/objs_norent/&M\" <OBJECTS> -o <TARGET>")
SET(CMAKE_C_LINK_EXECUTABLE   "plink.exe \"-S$ENV{DIGNUS_PROGRAM}/objs_norent/&M\" <OBJECTS> -o <TARGET>")
----------------------------------------

BTW, Regina is a Rexx processor -- it's running a script called cc.rex. If I invoke it directly:

C:\SVN\Dignus>"c:\Program Files\Regina\regina.exe"  cc.rex;dcc.exe   CMakeCCompilerId.c
Error 3 running "cc.rex;dcc.exe": Failure during initialization
Error 3.1: Failure during initialization: Program was not found

...which is what I'd expect. But the semicolon is still the problem here...

So, right at the end it is doing this:

Cmake is running the compiler you gave it.  Looks like:
regina.exe.


SET(CMAKE_C_COMPILER regina.exe cc.rex dcc.exe )
c:/SVN/Dignus/zosport.cmake(9):  SET(CMAKE_CXX_COMPILER regina.exe 
cc.rex dcxx.exe )

So, regina.exe is hanging forever.

To debug more, you could print out the exact command line CMake is 
trying to run.  Edit C:/Program Files (x86)/CMake 
2.8/share/cmake-2.8/Modules/CMakeDetermineCompilerId.cmake on line 96, 
and add a new line that does this:

message("${CMAKE_${lang}_COMPILER} ${CMAKE_${lang}_
COMPILER_ID_ARG1} ${CMAKE_${lang}_COMPILER_ID_FLAGS_LIST} ${testflags} 
${src}"

It does....  Add the above print, and try again.  Also, maybe run the 
command that CMake is running by hand and see if it hangs.  Since this 
is a toolchain file, you should be able to short circut the test 
altogether and set the information CMake is trying to figure out.
