I've tried to replace my whole /build.mk/ with your example:
SRC_HC_OPTS += -fPIC
SRC_CC_OPTS += -fPIC
And then got this error:

Should I add something else to this file?

BTW, this is the Makefile that builds the extension I mentioned:
https://github.com/albertov/pg_schedule/blob/master/Makefile.
When LINK_STATICALLY=TRUE it produces an '.so' which only links
dynamically to system libraries, all haskell libraries are linked
statically:

Hi,
I'm manage to link statically all haskell libraries to a
dynamically loadable postgreSQL extension written in haskell using:
SRC_HC_OPTS += -fPIC
SRC_CC_OPTS += -fPIC
in build.mk <http://build.mk> and passing these options to every
package cabal builds:
--ghc-option=-fPIC --ghc-option=-optc-fPIC
I'm using nix but it should work in any environment if you make
sure every package cabal build gets these options (maybe by
setting them in $HOME/.cabal/config?)
HTH,
Alberto

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.
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:
COPY my-build.mk <http://my-build.mk> /my-build.mk
<http://my-build.mk>
RUN mkdir /compile && cd /compile \
&& wget
https://downloads.haskell.org/~ghc/8.2.2/ghc-8.2.2-src.tar.xz
<https://downloads.haskell.org/%7Eghc/8.2.2/ghc-8.2.2-src.tar.xz>
\
&& tar -xvf ghc-8.2.2-src.tar.xz \
&& rm ghc-8.2.2-src.tar.xz \
&& cd ghc-8.2.2/ \
&& ./configure --prefix=/ghc-8.2.2-fpic
--disable-library-profiling --enable-shared \
&& cp /my-build.mk <http://my-build.mk> mk/build.mk
<http://build.mk> \
&& make install \
&& cd /usr/local/bin \
&& ls /ghc-8.2.2-fpic/bin/ | xargs -I{} ln -s
/ghc-8.2.2-fpic/bin/{}
And as you can see I just use my own prepared /my-build.mk
<http://my-build.mk>/ file which is:
SRC_HC_OPTS = -H64m -O
EXTRA_HC_OPTS = -fPIC
SRC_CC_OPTS = -fPIC -O
GhcStage1HcOpts = -fasm -O0
GhcStage2HcOpts = -fasm -O0
GhcLibHcOpts = -fasm -O2
GhcLibWays = v dyn
DYNAMIC_GHC_PROGRAMS = YES
DYNAMIC_BY_DEFAULT = NO
SplitObjs = NO
HADDOCK_DOCS = NO
BUILD_DOCBOOK_HTML = NO
BUILD_DOCBOOK_PS = NO
BUILD_DOCBOOK_PDF = NO
V = 1
LATEX_DOCS = NO
HSCOLOUR_SRCS = NO
BeConservative = YES
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:
cd /mnt
cabal update
cabal sandbox init
cabal install --enable-shared --ghc-option=-fPIC happy alex
cabal install --enable-shared --ghc-option=-fPIC
base-unicode-symbols filepath process directory lens
containers qm-interpolated-string
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 /-static/,
/-shared/ or /-fPIC/ means something here but it's work in
progress):
ghc -static -shared -fPIC -optc-DMODULE=Foo src/lib-autoinit.c
-outputdir builddir
ghc -package-db=SOME_CABALS_SANDBOX_PKGDB_DIR
--make-static-shared-fPIC src/Foo.hs
builddir/src/lib-autoinit.o -o builddir/libfoo.o -isrc
-outputdir builddir -Wall -O2
I failed with a lot of similar errors like this one:
/usr/bin/ld.gold: error:
/ghc-8.2.2-fpic/lib/ghc-8.2.2/ghc-prim-0.5.1.1/libHSghc-prim-0.5.1.1.a(Classes.o):
requires dynamic R_X86_64_PC32 reloc against 'stg_ap_0_fast'
which may overflow at runtime; recompile with -fPIC
What have I missed? What should I do to make this happen?
Any progress could be found here (Dockerfile, sources of
modules, build-scripts):
