llvm dev - Jun 2011 - [LLVMdev] HOWTO use llvm lit tool

Hi all,

Can anybody give a tutorial about how to use llvm-lit tool?

I copy and revise Makefile and lit.cfg etc from clang to my project.
However, when I run make test it always seem unable to find the FileCheck
tool correctly.

How can I fix it?

Can anybody add test feature to llvm/project/sample?


Thanks in advance!

best,

Yabin

Use llvm-lit --debug to see which config files are loaded.

In the clang/llvm trees, lit.cfg is loaded from lit.site.cfg, which is
Makefile-generated with this line
config.llvm_tools_dir=...

(I sometimes change that line manually to test different builds--currently a
pain).

Make sure the FileCheck too live there.

If not, you might try "llvm-lit --path=... "
