That error message looks like it's coming from TH instead of final
link, so you may need to do something else to make it available to TH
during compile.

Hello, I try to build a project which use C libraries.
during the developpement I want to link directly with the work in progress libraries. So I added this in cabal.
executable binoculars-ng [...]
if flag(useHklDev) pkgconfig-depends: gobject-2.0 ghc-options: -pgml ghc-options: gcc ghc-options: "-optl-Wl,--allow-multiple-definition" ghc-options: "-optl-Wl,--whole-archive,../../hkl/.libs/libhkl.a,--no-whole-archive" ghc-options: "-optl-Wl,--whole-archive,../../binoculars/libhkl-binoculars.a,--no-whole-archive"
at the end I have a working executable.
Building executable 'binoculars-ng' for hkl-0.1.0.0.. [1 of 1] Compiling Main ( app/Binoculars.hs, /home/experiences/instrumentation/picca/src/repo.or.cz/hkl/contrib/haskell/dist-newstyle/build/x86_64-linux/ghc-8.8.4/hkl-0.1.0.0/x/binoculars-ng/build/binoculars-ng/binoculars-ng-tmp/Main.o ) Linking /home/experiences/instrumentation/picca/src/repo.or.cz/hkl/contrib/haskell/dist-newstyle/build/x86_64-linux/ghc-8.8.4/hkl-0.1.0.0/x/binoculars-ng/build/binoculars-ng/binoculars-ng ...
But now I would like to create an unit test so I added this in cabal
test-suite hkl-test [...] if flag(useHklDev) pkgconfig-depends: gobject-2.0 ghc-options: -pgml ghc-options: gcc ghc-options: "-optl-Wl,--allow-multiple-definition" ghc-options: "-optl-Wl,--whole-archive,../../hkl/.libs/libhkl.a,--no-whole-archive" ghc-options: "-optl-Wl,--whole-archive,../../binoculars/libhkl-binoculars.a,--no-whole-archive"
but this time during the compilation I end up with this error message

both the executable and the test use this hkl_binoculars_cube_free function.
So are you aware of a difference between test suit and executable during the build.
more precisely are both executables compiled differently ?
thanks for you help
Frederic
