I have not done cmake builds for a while.
I did a :
cmake /source tree
make
and all seems okay
but then many tests fail when i do a
make check
I'm using pristine tip of the llvm tree.
Ideas?
TIA.

Hi Reed,
but then many tests fail when i do a "make check"
That's not normal (all tests pass for me on Linux and OS X). Is this
on your build machine, or a MIPS board with some odd
cross-compilation? The latter is more likely to have weird CMake
issues (I know AArch64 does if you're not careful).
Ideas?
Only the usual: pick a (preferably simple) test and try to work out
what's going on; "llvm-lit -v /path/to/test" is useful to save time
when you want to see if you've fixed an individual test; run the
command it prints out and see if you can see why it's failing...
One of the "make check" failure outputs (from a single test) might be
recognised by someone if you can post it. (For crashes llvm-lit often
only reports something about there being no output though. Obviously
that's useless).
Cheers.
Tim.
Do you use a -G on the cmake?
And if so which one.

I use "-G Ninja" these days. I'm not actually convinced it's
significantly better than the default, but some weird habit I suppose.
But both work the same for me (I've just checked without).
Cheers.

I'm just running this on x86 ubuntu.
after
cd $build_dir
cmake $src_root
make
The first strange this is that if I go into build_dir/test and type "make", it does nothing.
In $build_dir, with "make check", I get errors like:
/home/rkotler/llvmc/build/test/Analysis/CostModel/X86/Output/uitofp.ll.script: line 1: /home/rkotler//home/rkotler/llvmc/build/./bin/llvmc/build/./bin/llc: No such file or directory
Certainly, ./bin/llc exists
rkotler@mipssw006:~/llvmc/build$ ls ./bin/llc
./bin/llc
It would go better if you didn't work on the directory "llvmc".
See llvm/test/lit.cfg. There are many kluges...

I don't think there is a rule in CMake to "make" inside test. You
should use make check.

/home/rkotler//home/rkotler/ looks wrong.

That is really crazy.I think kluge needs a capital K here.
Changing the directory name from /home/rkotler/llvmc/build to /home/rkotler/compmc/build fixed the problem.
Lol.
