<html><head><meta http-equiv="Content-Type" content="text/html charset=us-ascii"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class="">Hi,<div class=""><br class=""></div><div class="">I'm writing a program analyzer that operates on GHC Core. Currently, I'm using the GHC API to get Core from .hs files. I'd like to be able to run this analysis on the standard libraries that come with GHC, which requires getting those as Core.</div><div class=""><br class=""></div><div class="">Unfortunately, the build process for these libraries is not entirely straightforward, and relies on a make script. I eventually came up with the plan of writing a GHC plugin, which, rather than performing any optimizations, would simply run the analysis, and then print the results out to a file. I was able to write the plugin successfully, and test it on several files that were <i class="">not</i> from the base library.</div><div class=""><br class=""></div><div class="">Then, i turned to modify the GhcLibHcOpts flag in mk/build.mk, so that the make script would call the plugin. I ended up with the following:</div><div class=""><br class=""></div><div class="">GhcLibHcOpts = -package-db /usr/local/lib/ghc-8.0.2/package.conf.d -package-db /Users/BillHallahan/.ghc/x86_64-darwin-8.0.2/package.conf.d -package hplugin -fplugin HPlugin.Plugin -v</div><div class=""><br class=""></div><div class="">The two package databases are to get to (1) the GHC API and (2) the plugin ("hplugin") itself. With this I get an error message, which I have not been able to find a way to resolve:</div><div class=""><div style="margin: 0px; font-size: 11px; line-height: normal; font-family: Menlo;" class=""><span style="font-variant-ligatures: no-common-ligatures" class=""><br class=""></span></div><div style="margin: 0px; font-size: 11px; line-height: normal; font-family: Menlo;" class=""><div style="margin: 0px; line-height: normal;" class=""><span style="font-variant-ligatures: no-common-ligatures" class="">"inplace/bin/ghc-stage1" -hisuf hi -osuf o -hcsuf hc -static -H32m -O -Wall -this-unit-id ghc-prim-0.5.0.0 -hide-all-packages -i -ilibraries/ghc-prim/. -ilibraries/ghc-prim/dist-install/build -ilibraries/ghc-prim/dist-install/build/autogen -Ilibraries/ghc-prim/dist-install/build -Ilibraries/ghc-prim/dist-install/build/autogen -Ilibraries/ghc-prim/. -optP-include -optPlibraries/ghc-prim/dist-install/build/autogen/cabal_macros.h -package-id rts -this-unit-id ghc-prim -XHaskell2010 -package-db /usr/local/lib/ghc-8.0.2/package.conf.d -package-db /Users/BillHallahan/.ghc/x86_64-darwin-8.0.2/package.conf.d -package hplugin -fplugin HPlugin.Plugin -no-user-package-db -rtsopts -Wno-trustworthy-safe -Wno-deprecated-flags -Wnoncanonical-monad-instances -odir libraries/ghc-prim/dist-install/build -hidir libraries/ghc-prim/dist-install/build -stubdir libraries/ghc-prim/dist-install/build -split-objs -dynamic-too -c libraries/ghc-prim/./GHC/Types.hs -o libraries/ghc-prim/dist-install/build/GHC/Types.o -dyno libraries/ghc-prim/dist-install/build/GHC/Types.dyn_o</span></div><div style="margin: 0px; line-height: normal;" class=""><span style="font-variant-ligatures: no-common-ligatures" class=""><command line>: not built for interactive use - can't load plugins (HPlugin.Plugin)</span></div><div style="margin: 0px; line-height: normal;" class=""><span style="font-variant-ligatures: no-common-ligatures" class="">make[1]: *** [libraries/ghc-prim/dist-install/build/GHC/Types.o] Error 1</span></div><div style="margin: 0px; line-height: normal;" class=""><span style="font-variant-ligatures: no-common-ligatures" class="">make: *** [all] Error 2</span></div><div class=""><span style="font-variant-ligatures: no-common-ligatures" class=""><br class=""></span></div></div></div><div class="">So I'm now wondering (an answer to either of these two questions would be helpful):</div><div class="">(1) Is this a viable path?
