Dear GHC Devs, This is my first time trying to compile GHC on my machine and I need a little help to go on. I ran into a problem, I get a lot of undefined reference errors when linking. A sample of these: ghc\stage2\build\Main.o:fake:(.text+0x1f3): undefined reference to `ghczmprim_GHCziTypes_ZC_con_info' ghc\stage2\build\Main.o:fake:(.text+0x340): undefined reference to `ghczmprim_GHCziTypes_ZMZN_closure' ghc\stage2\build\Main.o:fake:(.text+0x498): undefined reference to `ghczmprim_GHCziTypes_False_closure' ghc\stage2\build\Main.o:fake:(.text+0x4c0): undefined reference to `ghczmprim_GHCziTypes_True_closure' Before the errors I have a warning: Warning: -rtsopts and -with-rtsopts have no effect with -no-hs-main. Call hs_init_ghc() from your main() function to set these options. The only change I made is fixing some simple type errors in utils/ghc-cabal/Main.hs that stopped compilation.
