Compiles and installs the specified GHC version into
a self-contained "~/.ghcup/ghc/<ghcver>" directory
and symlinks the ghc binaries to "~/.ghcup/bin/<binary>-<ghcver>".
This also allows building a cross-compiler. Consult the documentation
first: <https://gitlab.haskell.org/ghc/ghc/-/wikis/building/cross-compiling#configuring-the-build>
ENV variables:
Various toolchain variables will be passed onto the ghc build system,
such as: CC, LD, OBJDUMP, NM, AR, RANLIB.
Examples:
# compile from known version
ghcup compile ghc -j 4 -v 8.4.2 -b 8.2.2
# compile from git commit/reference
ghcup compile ghc -j 4 -g master -b 8.2.2
# specify path to bootstrap ghc
ghcup compile ghc -j 4 -v 8.4.2 -b /usr/bin/ghc-8.2.2
# build cross compiler
ghcup compile ghc -j 4 -v 8.4.2 -b 8.2.2 -x armv7-unknown-linux-gnueabihf --config $(pwd)/build.mk -- --enable-unregisterised|]
compileHLSFooter = [s|Discussion:
Compiles and installs the specified HLS version.
The --ghc arguments are necessary to specify which GHC version to build for/against.
2021-10-15 20:24:23 +00:00
These need to be available in PATH prior to compilation.
Examples:
# compile 1.7.0.0 from hackage for 8.10.7, running 'cabal update' before the build
ghcup compile hls --version 1.7.0.0 --ghc 8.10.7 --cabal-update
2022-07-09 18:27:55 +00:00
# compile from master for ghc 9.2.3 using 'git describe' to name the binary and ignore the pinned index state
ghcup compile hls -g master --git-describe-version --ghc 9.2.3 -- --index-state=@(date '+%s')
# compile a specific commit for ghc 9.2.3 and set a specifc version for the binary name
ghcup compile hls -g a32db0b -o 1.7.0.0-p1 --ghc 9.2.3|]
