Missing functions in GHC's RTS?
At 2001-08-03 00:41, I wrote (on the Haskell Cafe list):
When I make a function generator with "foreign export dynamic", GHC spits out stub files which it apparently then needs for the link. What are these for?
OK, so I don't know what they are, but the link needs the _stub.o file. Unfortunately, the stub file includes these symbols: rts_getWord8 rts_getWord16 rts_getInt16 rts_getInt64 ...which do not appear to be in any library and indeed are not declared in RtsAPI.h, although corresponding rts_mk* functions are. This looks like a bug in GHC. $ ghc -v Glasgow Haskell Compiler, Version 5.00, for Haskell 98, compiled by GHC version 5.00 Using package config file: /usr/lib/ghc-5.00/package.conf Hsc static flags: -static -fignore-interface-pragmas -fomit-interface-pragmas -fdo-lambda-eta-expansion -flet-no-escape $ uname -a Linux server 2.2.19pre17 #1 Tue Mar 13 22:37:59 EST 2001 i686 unknown -- Ashley Yakeley, Seattle WA
That looks like an omission; I've checked in impls for
the missing getter routines.
