Cannot get infer to compile clang

[ab4359]

I cannot get clang to compile when cloning the latest version of infer in a Ubuntu 16.04 LTS VM using VMware Fusion. I am following the instructions and get this as the end of output when I run ./build-infer.sh clang:

  compilation failure; you can try running

    make clean
    './build-infer.sh' clang

Other times the build has failed in the mid 90% range.

I've experienced the same problem when trying to install in Ubuntu 18.04.2
Packages are installed as follows:

The OOM (out of memory) killer on Linux is killing the linking step of clang (which is notoriously memory-intensive).

You can try increasing the RAM in the VM, or, potentially, using fewer jobs (e.g., try setting _NPROCESSORS_ONLN and JOBS to 1).

There's also some other way to tell the infer build process to accept a build of clang, which you've "manually completed" (i.e., rather than making infer build clang all again, you can go to the clang folder---probably in /tmp---, run make, copy the artefacts into the infer source tree, and then continue the infer build). I'll try to find that for you.

This is what I was referring to (about completing a build): #649 (comment)

Solved. Allocated 12GB of RAM and 80GB of hard disk space to the VM to get it to clang to complete the compile.
