The ghc-options are not passed to the linker #9589
Description
While fixing a bug that turned out to be another case of #7339, I realized that the ghc-options field is not being passed to a linker invocation of ghc after having compiled the haskell modules and extra build sources (see buildOrReplLib).
You can see that the linker options e.g. start from mempty instead of baseOpts (where baseOpts has already added to ghcOptExtra the ghc-options specified in the cabal file or flags). This happens for ghcSharedOpts, however, the ghcOptExtra seems to be added in that case. I haven't further diagnosed.
linkerOpts =
+ -- (Shouldn't this be `baseOpts` as well? If not,
+ -- then ghcOptsExtra is not being considered in the linker invocation.)
- mempty
+ baseOpts
{ ghcOptLinkOptions =
PD.ldOptions libBi
++ [ "-static"
| withFullyStaticExe lbiThe initial attempted fix (that turned out to be fixed by the patch that fixed #7339) was to add
ghc-options: -optc-Wl,-rpath,/path...
which did not work because, even though it gets passed to the ghc --make invocation that compiles haskell modules, it does not get passed on to the linker invocation that links them together.
