[CMake] Porting cmake to OS/390

Tue Dec 19 05:57:48 EST 2006

Hi,

I have now after a few, well to be honest many, trials found out the cause 
of my initial errors. The flex generated files are generated on ASCII 
platforms. The generated files will not work out of the box on a platform 
whos using a character set as EBCDIC!

First I tried regenerating the lex files using the available flex 2.5.4a on 
our mainframe. Did not work. CMake is using a later flex wich is not 
available on mainframes...
Second I tried porting a flex version that would produces correct output but 
did not quite succeed.
After banging my head at least ten times on the wall and reading numerous 
mail group posts I found the idea that one could manually alter the flex 
generated lookup tables to suit the ebcdic platform.

This actually worked and I'm now looking for input on the next obstacle. 
When cmake itself is bootstrapping I get the following output.

IBMUSER:/code/cmake/cmake-2.4.3: > Bootstrap.cmk/cmake . 
-C"Bootstrap.cmk/InitialCacheFlags.cmake" -G"Unix Makefiles"

loading initial cache file Bootstrap.cmk/InitialCacheFlags.cmake

I suspect that the failure to compile has to do with the order of arguments 
given to the compiler. I had to modify the bootstrap sligthly and put the -o 
outfile before any source to get things to work.
Eg.
c++ -o hello hello.c     OK
c++ hello.c -o hello     NOT OK

There also seem to be a problem with the output of uname -s since the result 
contains a /
What is a good workaround for this?

As always - Suggestions and hints are welcome especially on a way to declare 
the order of parameters to the c++ compiler.

Once I got this running I will of course post a detail description on howto 
to get cmake to run on OS/390!!!
