This example will cover building a very recent version of LLVM using the CLang compiler. User's may first want to visit HPRC's EasyBuild page and a previous example of modifying an existing easyconfig.
Contents
Motivation
A user wants to build a modified version of the LLVM module that includes:
- a recent source from the LLVM Github repository
- adds support for CLang
LLVM is a rather long build (several hours using a single-processor). Additionally, the currently installed versions do not include CLang support. They are also rather dated (v9.01 released December 20, 2019). Newer releases include v10.0.1, released August 6, 2020. An even newer release candidate includes v11.0.0-rc5 released September 30, 2020 but as of this writing on October 3, 2020, there are already 7681 commits to master since this release. So, for this example we will use a recent (10/3/2020) .zip file of the master repo. Notes for using a bleeding edge (as of this moment) clone of the master repo are included below and are left as an exercise to the reader.
