I am running the following script to build GHC from sources (ghc-8.6.2-src.tar.xz) on OpenBSD (-CURRENT):
{{{ #! /bin/sh set -e
BUILD_DIR=/usr/local/tmp-build-ghc
export AUTOCONF_VERSION=2.69 export AUTOMAKE_VERSION=1.16
if [ ! -n "$1" ]; then echo "ERROR: Provide path for ghc source." exit 1 fi
echo "Extracting ghc source files from ${1} to ${BUILD_DIR} ..." mkdir -p $BUILD_DIR
cd $BUILD_DIR xzcat $1 | tar xvf -
GHC_DIR=`ls | grep ghc` cd $GHC_DIR
echo "Cleaning up OpenBSD-incompatible commands..." find . -type f | xargs sed -i -e 's|^ln -f -v |ln -f |'
echo "Building GHC... " export CC=/usr/bin/clang
./boot ./configure --with-iconv-libraries=/usr/local/lib \ --with-iconv-includes=/usr/local/include \ --with-gmp-libraries=/usr/local/lib \ --with-gmp-includes=/usr/local/include \ --with-ffi-libraries=/usr/local/lib \ --with-ffi-includes=/usr/local/include \ --with-system-libffi gmake }}}
I will file a separate bug report for the **ln** incompatibility with the unsupported **-v** flag.
When compiling GHC, I get the following error:
{{{
