llvm/clang compile error with Memory exhausted

问题

I am trying to build the latest llvm/clang code on my ubuntu 14.04 vm, which has 2GB memory.

What I did is a normal configure/make procedure, without any parameters to these two commands.

at last, I have the following error:

llvm[4]: Linking Debug+Asserts executable clang
/usr/bin/ld: failed to set dynamic section sizes: Memory exhausted
collect2: error: ld returned 1 exit status
make[4]: *** [/home/alex/Downloads/llvm_build/Debug+Asserts/bin/clang] Error 1
make[4]: Leaving directory /home/alex/Downloads/llvm_build/tools/clang/tools/driver' make[3]: *** [driver/.makeall] Error 2 make[3]: Leaving directory/home/alex/Downloads/llvm_build/tools/clang/tools'
make[2]: * [all] Error 1
make[2]: Leaving directory /home/alex/Downloads/llvm_build/tools/clang' make[1]: *** [clang/.makeall] Error 2 make[1]: Leaving directory/home/alex/Downloads/llvm_build/tools'
make: *** [all] Error 1

Does anyone know how to resolve this?

回答1:

You need to do one of the following:

1. Add more RAM to your VM, or
2. Use gold instead of ld as a linker, or
3. Build Release(-DCMAKE_BUILD_TYPE=Release), not Debug build

Another consideration: If you have Make running parallel jobs (e.g., make -j8), the concurrently executing jobs may require too much memory.
