C compiler doesn't works

Hi, I tried to setup and test gllvm follow the readme, but failed to pass the test with pkg-config.
I am using Ubuntu18.04 server, all the required dependencies are installed I think, but I don't know the test always fail, the following are the output log:
User@51195d5b6a9c:~/pkg-config-0.26$ CC=gclang ./configure
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes

checking whether the C compiler works... no
configure: error: in `/home/pkg-config-0.26':

See `config.log' for more details
Take a look at what gsanity-check
tells you.
Also take a close look at the config.log
Every thing goes well if I use wllvm
to compile, I think gllvm
and wllvm
share the same dependency, but it's weird gllvm can't work.
Here is the gsanity-check
output, which I think is no problem:
User@51195d5b6a9c:~/go/bin$ ./gsanity-check
Version info: gsanity-check version 1.2.7
Released: August 4 2020
Logging output to standard error.
Logging level not set, using default of WARNING.
Logging configuration uses the environment variables:
WLLVM_OUTPUT_LEVEL and WLLVM_OUTPUT_FILE.
Happily sitting atop "linux" operating system.
The C compiler clang is:
clang version 10.0.0
The CXX compiler clang++ is:
clang version 10.0.0
The bitcode linker llvm-link is:
LLVM version 10.0.0
The bitcode archiver llvm-ar is:
LLVM version 10.0.0
Not using a bitcode store.
I think the problem may be pointed out in the config.log
, but I don't know how to fix it:
configure:3064: checking for gcc
configure:3091: result: gclang
configure:3320: checking for C compiler version
configure:3329: gclang --version >&5
./configure: line 3331: gclang: command not found
configure:3340: $? = 127
configure:3329: gclang -v >&5
./configure: line 3331: gclang: command not found
When we use wllvm
, we should type export LLVM_COMPILER=clang
before running CC=wllvm ./configure
, so is there any similar setting for gllvm
?
OK, I have fixed the problem, user should add the $GOPATH/bin
to the PATH
, or gclang
will not be found
