#4153: GHCi linker should load archives
---------------------------------+------------------------------------------
Reporter: batterseapower | Owner:
Type: bug | Status: new
Priority: normal | Component: GHCi
Version: 6.12.3 | Keywords:
Os: Unknown/Multiple | Testcase:
Architecture: Unknown/Multiple | Failure: None/Unknown
---------------------------------+------------------------------------------
It looks like the GHCi linker doesn't look for '.a' files, only '.o's,
e.g. Linker.lhs line 1107:
{{{
mk_obj_path dir = dir </> (lib <.> "o")
}}}
There is no corresponding call to findFile with a "a" suffix.
This is annoying because it prevents you from running programs using the
llvm package in GHCi. The llvm package depends on a number of .a files:
{{{
ld-options: ...
-lLLVMCore -lLLVMAlphaInfo -lLLVMSupport -lLLVMSystem
-L/usr/local/lib
...
}}}
And:
{{{
$ ls /usr/local/lib | grep LLVMCore
libLLVMCore.a
}}}
The net result is that we get this error when trying to run a program
using llvm in GHCi:
{{{
$ runghc BrainF.hs
BrainF.hs: <command line>: can't load .so/.DLL for: LLVMSystem
(dlopen(libLLVMSystem.dylib, 9): image not found)
}}}
Another argument for finding some way to co-opt the system linker to do
linking for us?
