it does work
however, that doesnt change the fact it's wrong ... users should never change files in /etc/env.d/ since those changes will be lost next time a package is emerged
the changes should go in /etc/profile and should be something like:
PATH="/usr/lib/ccache/bin:${PATH}"
It doesn't work : the advertised procedure adds /usr/lib/ccache/bin in the PATH variable *AFTER* /usr/bin , which is hardcoded in /etc/profile. I've altered the instructions to use /etc/profile instead of any /etc/env.d files. |
The handbook says : ---- If you would like to use ccache for non-Portage compilations, add /usr/lib/ccache/bin to the beginning of your PATH variable (before /usr/bin). This can be accomplished by editing /etc/env.d/00basic: Code Listing 9: Editing /etc/env.d/00basic PATH="/usr/local/bin:/opt/bin:/usr/lib/ccache/bin" ---- but it doesn't work, even by adding the line ROOTPATH="/usr/local/bin:/opt/bin:/usr/lib/ccache/bin" Reproducible: Always Steps to Reproduce: 1.Read the handbook 2.edit /etc/env.d/00basic 3.env-update && source /etc/profile 4.which gcc Actual Results: it prints : /usr/bin/gcc ccache is not used Expected Results: It should have printed /usr/lib/ccache/bin/gcc meaning that ccache is used That seems to come from /etc/profile which hard-codes the position of /usr/bin in the path. I don't know if it's a /etc/profile bug, but it's clearly a documentation bug, since the proposed method does not work. I guess there are other ways to change the PATH, which sould be advertised in the handbook.
