<p>Hi there. My actual main goal is to
build my own shared library written in
Haskell that would be compatible with
application written in C even without
knowing that is is written in Haskell.
So for now I compiled my shared library
but I only could dynamically link it to
Haskell dependencies such as "base" and
"ghc-prim" packages. But I want to
statically link Haskell dependencies but
I realized it isn't simple and
straightforward task.</p>
<p>On Freenode's #haskell I was advised I
should build GHC from scratch with
-fPIC, on the Linux (I'm using Fedora
Workstation 25 on x86_64) I couldn't go
forward without this step. So I wrote
some Dockerfile based on Debian 9,
skipping first part which is containing
'apt-get update' and installing
'build-essential' here is what I have:</p>
<tt>COPY <a href="http://my-build.mk" target="_blank">my-build.mk</a>
/<a href="http://my-build.mk" target="_blank">my-build.mk</a></tt><tt><br>
</tt><tt><br>
</tt><tt>RUN mkdir /compile && cd
/compile \</tt><tt><br>
</tt><tt> && wget <a class="m_5901498364755408491gmail-m_-3108370329929368587m_1732321520409461621moz-txt-link-freetext" href="https://downloads.haskell.org/%7Eghc/8.2.2/ghc-8.2.2-src.tar.xz" target="_blank">https://downloads.haskell.org/<wbr>~ghc/8.2.2/ghc-8.2.2-src.tar.x<wbr>z</a>
\</tt><tt><br>
</tt><tt> && tar -xvf
ghc-8.2.2-src.tar.xz \</tt><tt><br>
</tt><tt> && rm
ghc-8.2.2-src.tar.xz \</tt><tt><br>
</tt><tt> && cd ghc-8.2.2/ \</tt><tt><br>
</tt><tt> && ./configure
--prefix=/ghc-8.2.2-fpic
--disable-library-profiling
--enable-shared \</tt><tt><br>
</tt><tt> && cp /<a href="http://my-build.mk" target="_blank">my-build.mk</a>
mk/<a href="http://build.mk" target="_blank">build.mk</a>
\</tt><tt><br>
</tt><tt> && make install \</tt><tt><br>
</tt><tt> && cd /usr/local/bin
\</tt><tt><br>
</tt><tt> && ls
/ghc-8.2.2-fpic/bin/ | xargs -I{} ln -s
/ghc-8.2.2-fpic/bin/{}</tt><br>
<p>And as you can see I just use my own
prepared <i><a href="http://my-build.mk" target="_blank">my-build.mk</a></i>
file which is:</p>
<tt>SRC_HC_OPTS = -H64m -O</tt><tt><br>
</tt><tt>EXTRA_HC_OPTS = -fPIC</tt><tt><br>
</tt><tt>SRC_CC_OPTS = -fPIC -O</tt><tt><br>
</tt><tt>GhcStage1HcOpts = -fasm -O0</tt><tt><br>
</tt><tt>GhcStage2HcOpts = -fasm -O0</tt><tt><br>
</tt><tt>GhcLibHcOpts = -fasm -O2</tt><tt><br>
</tt><tt>GhcLibWays = v dyn</tt><tt><br>
</tt><tt>DYNAMIC_GHC_PROGRAMS = YES</tt><tt><br>
</tt><tt>DYNAMIC_BY_DEFAULT = NO</tt><tt><br>
</tt><tt>SplitObjs = NO</tt><tt><br>
</tt><tt>HADDOCK_DOCS = NO</tt><tt><br>
</tt><tt>BUILD_DOCBOOK_HTML = NO</tt><tt><br>
</tt><tt>BUILD_DOCBOOK_PS = NO</tt><tt><br>
</tt><tt>BUILD_DOCBOOK_PDF = NO</tt><tt><br>
</tt><tt>V = 1</tt><tt><br>
</tt><tt>LATEX_DOCS = NO</tt><tt><br>
</tt><tt>HSCOLOUR_SRCS = NO</tt><tt><br>
</tt><tt>BeConservative = YES</tt>
<p>I just combined it from parts I found
in the internet during searching answers
to my questions. So I built this
container, I also installed dependencies
by this commands:</p>
<tt>cd /mnt</tt><tt><br>
</tt><tt>cabal update</tt><tt><br>
</tt><tt>cabal sandbox init</tt><tt><br>
</tt><tt>cabal install --enable-shared
--ghc-option=-fPIC happy alex</tt><tt><br>
</tt><tt>cabal install --enable-shared
--ghc-option=-fPIC base-unicode-symbols
filepath process directory lens
containers qm-interpolated-string</tt><br>
<p>And when I tried to build my app by
following commands (first command
compiles some C-code to automatically
initialize Haskell runtime, see link
posted below, not sure if <i>-static</i>,
<i>-shared</i> or <i>-fPIC</i> means
something here but it's work in
progress):</p>
