Build Error

Clang Frontend

Hi,

I’m trying to build Clang on Redhat Linux. I recevied the following error

llvm[3]: Compiling SimplifyLibCalls.cpp for Debug+Asserts build
llvm[3]: Compiling Sink.cpp for Debug+Asserts build
llvm[3]: Compiling TailDuplication.cpp for Debug+Asserts build
llvm[3]: Compiling TailRecursionElimination.cpp for Debug+Asserts build
llvm[3]: Building Debug+Asserts Archive Library libLLVMScalarOpts.a
make[3]: *** [/root/llvm/Debug+Asserts/lib/libLLVMScalarOpts.a] Error 1
make[3]: Leaving directory /root/llvm/lib/Transforms/Scalar' make[2]: *** [Scalar/.makeall] Error 2 make[2]: Leaving directory /root/llvm/lib/Transforms’
make[1]: *** [Transforms/.makeall] Error 2
make[1]: Leaving directory `/root/llvm/lib’
make: *** [all] Error 1

-Any suggestions on how I could resolve this?

Thanks,
Prasanth

Hard to say, because it doesn't say what the failure is. I'd try make clean and then rebuild.

Hi Prasanth,
There isn't enough information in your mail. We don't even know how
you ran make. If you run

make VERBOSE=1

it will display the commands executed by make. Perhaps that would give
an indication as to what the problem is.

It seems, you’ve ran make with -jN. One thread failed compiling and printed error, but other threads continued working and printing stuff. So, the error message was left somewhere earlier.

Yes. Look earlier for the actual error.
