i installed the default version of clang and llvm in my ubuntu 14.04 and it's version 3.4. That's nice, but for some legacy stuff i need version 2.9.

Ideally, i could install both version in parallel and use them with "clang-3.4 test.c" and "clang-2.9 test.c" while choosing which version a plain "clang test.c" refers to by default.

Indeed, the package for "clang" appears to be only 50KB in size, so something is going on.

Question: how can i have several version of clang installed in parallel?

llvm makes binaries for version 2.9 available on its website:

http://llvm.org/releases/download.html#2.9

thanks.

My google keywords were: install multiple version package in ubuntu. CMIIW.

  • thanks, but all that only applies if the older version is in the repo. Also i couldnt find how to change what "clang" refers/redirects to. i fell like i am missing some term/expression in my google search... :/ – Eduard Schreder Aug 01 '14 at 14:34
