Hi Brian,
The cmake-line should be...
# apt-get install ninja-build
$ cmake -G Ninja ../llvm
Unfortunately, on the latest Git my build fails which gcc-7 (see
attached file for details).
Do I really need to build clang-from-git?
I have llvm-7/clang-7 binaries installed on my system?
But I run the test after symlinking clang-7 ---> clang...
$ ./bin/llvm-lit -v ./tools/clang/test/Sema/asm.c
llvm-lit: /home/sdi/src/llvm/llvm/utils/lit/lit/llvm/config.py:334:
note: using clang: /usr/bin/clang
llvm-lit: /home/sdi/src/llvm/llvm/utils/lit/lit/llvm/subst.py:126:
note: Did not find c-index-test in
/home/sdi/src/llvm/build/./bin:/home/sdi/src/llvm/build/./bin
llvm-lit: /home/sdi/src/llvm/llvm/utils/lit/lit/llvm/subst.py:126:
note: Did not find clang-check in
/home/sdi/src/llvm/build/./bin:/home/sdi/src/llvm/build/./bin
llvm-lit: /home/sdi/src/llvm/llvm/utils/lit/lit/llvm/subst.py:126:
note: Did not find opt in
/home/sdi/src/llvm/build/./bin:/home/sdi/src/llvm/build/./bin
-- Testing: 1 tests, 1 threads --
PASS: Clang :: Sema/asm.c (1 of 1)
Testing Time: 0.23s
Expected Passes : 1
Looks good?
Thanks.
Regards,
