[CMake] FW: cmake newbie questions

[Phil Smith]

I found cmakeerror.log, which helped me get past the FAILED errors. But now I'm back to the "Could not COPY FILE" errors:

And I have NO clue that those mean.

Any clues how to do that?  I see this in CMakeCache.txt:

HAVE_SIZEOF_LONG_LONG:INTERNAL=FALSE
HAVE_SIZEOF_UNSIGNED_INT:INTERNAL=FALSE
HAVE_SIZEOF_UNSIGNED_LONG:INTERNAL=FALSE
HAVE_SIZEOF_UNSIGNED_LONG_LONG:INTERNAL=FALSE
HAVE_SIZEOF_UNSIGNED_SHORT:INTERNAL=FALSE
//Result of CHECK_TYPE_SIZE
SIZEOF_LONG_LONG:INTERNAL=
//Result of CHECK_TYPE_SIZE
SIZEOF_UNSIGNED_INT:INTERNAL=
//Result of CHECK_TYPE_SIZE
SIZEOF_UNSIGNED_LONG:INTERNAL=
//Result of CHECK_TYPE_SIZE
SIZEOF_UNSIGNED_LONG_LONG:INTERNAL=
//Result of CHECK_TYPE_SIZE
SIZEOF_UNSIGNED_SHORT:INTERNAL=

...but that's about it.

Anyway, I wasn't clear: the same person isn't likely to be doing z/OS
and Windows on the same machine. But since the same CMakeLists.txt is to
be used, I didn't want to hard-code anything in there. I've changed to
-G -- somehow I missed that before (I did look, honest!).

You really want out of source builds.   You have to give the path to the
source tree.  First make sure the source tree you are working on has not
had cmake run on it (no CMakeCache.txt, or other generated files).
Then, you do this:

cmake -G"Unix Makefiles" ../path/to/your/source

Note, the ../path/to/your/source.  That is important.

Are those "failed" messages significant? I was brought up not to ignore
errors without understanding them!


Failing on check size of is not a good thing, and I would track that
down if I were you...
