| # Brief explanation of the bootstrap logic: |
| # |
| # Previous ghc ebuilds have been split into two: ghc and ghc-bin, |
| # where ghc-bin was primarily used for bootstrapping purposes. |
| # From now on, these two ebuilds have been combined, with the |
| # binary USE flag used to determine whether or not the pre-built |
| # binary package should be emerged or whether ghc should be compiled |
| # from source. If the latter, then the relevant ghc-bin for the |
| # arch in question will be used in the working directory to compile |
| # ghc from source. |
| # |
| # This solution has the advantage of allowing us to retain the one |
| # ebuild for both packages, and thus phase out virtual/ghc. |
| |
| # Note to users of hardened gcc-3.x: |
| # |
| # If you emerge ghc with hardened gcc it should work fine (because we |
| # turn off the hardened features that would otherwise break ghc). |
| # However, emerging ghc while using a vanilla gcc and then switching to |
| # hardened gcc (using gcc-config) will leave you with a broken ghc. To |
| # fix it you would need to either switch back to vanilla gcc or re-emerge |
| # ghc (or ghc-bin). Note that also if you are using hardened gcc-3.x and |
| # you switch to gcc-4.x that this will also break ghc and you'll need to |
| # re-emerge ghc (or ghc-bin). People using vanilla gcc can switch between |
| # gcc-3.x and 4.x with no problems. |
| |
| EAPI="5" |
| |
| # to make make a crosscompiler use crossdev and symlink ghc tree into |
| # cross overlay. result would look like 'cross-sparc-unknown-linux-gnu/ghc' |
| # |
| # 'CTARGET' definition and 'is_crosscompile' are taken from 'toolchain.eclass' |
