Comment(by simonmar):

 Replying to [comment:20 SamAnklesaria]:
  Thanks for the comments. `parseName` relies internally on a function
 from HscMain that does just that: name parsing.  I don't think it can
 handle import declarations, which is why I wrote `hscImport`.

 Yes - I'm just suggesting that instead of `getImportDecl` you call it
 `parseImportDecl` and make it parse a complete import declaration for
 consistency.

  As I removed the import from the string the user entered (saving all
 the import parts in a `remembered_ctx` seems redundant), it needs to be
 prepended or the parser won't understand it.

 My suggestion is to not remove it in the first place, that seems simpler.

Comment:

 I'm not entirely sure, but I suspect it's wrong for a header file to be
 defining these symbols.  Which header is defining them?

 Perhaps a better way to fix this would be to undefine the symbols after
 including `papi.h`, rather than unconditionally in `PosixSource.h`.  That
 would at least make the workaround more localised.

Comment(by malcolm.wall...@…):

 Perhaps one solution might be to have two different LANGUAGE pragmas for
 CPP, to allow the file to choose its desired behaviour for the
 preprocessor, e.g. CPP and CPPKeepCComments.  (Or with the alternative
 default choice, CPP and CPPStripCComments.)

Comment:

 I think the default will have to stay as it is (i.e. stripping C
 comments).

 You can use
 {{{
 {-# LANGUAGE CPP #-}
 {-# OPTIONS_GHC -optP -C #-}
 }}}
 if you know you want comments to be kept.

 if it doesn't find an FD in the Handle, it uses the normal buffered

 optionally provide `RawIO`, but that's something for another day.

 Hi Simon,

 Since the original report I've made a fresh install of GHC 6.12.3, and I'm
 afraid I can't even get my originally offending code to reproduce the
 linker error.  If I encounter this error message again later (in this
 project or others), I'll submit a new ticket and try to keep my system
 consistent long enough to get it to replicate for you.

 Sorry I can't be of more help.

 Kind Regards,
 Orion

 It's tricky to fix the

[GHC] #4153: GHCi linker should load archives

 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?

Comment:

 No response from submitter, and it's not clear to me that there's
 necessarily a bug here anyway.

Comment:

 It looks like the chain of includes that causes the problem is:
 {{{papi.h -- sys/types.h -- features.h}}}

 This is on a Fedora 12 installation. The actual error is:
 {{{
 In file included from rts/Papi.c:19:
 rts/PosixSource.h:19:1: error: _POSIX_C_SOURCE redefined
 In file included from /usr/include/sys/types.h:27,
  from /usr/include/papi.h:49,
  from rts/Papi.c:17:
 /usr/include/features.h:210:1: error: this is the location of the previous
 definition
 }}}

 which is the result of this command:
 {{{
 /usr/lib64/ccache/gcc -E  -DPROFILING -DTHREADED_RTS -DDEBUG
 -Wall -Werror -Wall -Wextra -Wstrict-prototypes  -Wmissing-prototypes
 -Wmissing-declarations -Winline -Waggregate-return -Wpointer-arith
 -Wmissing-noreturn -Wnested-externs -Wredundant-decls
 -Iincludes -Irts -DCOMPILING_RTS  -fno-strict-aliasing -fno-common
 -DUSE_PAPI -Ilibffi/build/include   -fomit-frame-pointer
 -DRtsWay=\rts_v\ -Wno-strict-prototypes
 -MM rts/Papi.c
 -MF rts/dist/build/.depend-v-dyn-l-debug-thr-thr_debug-thr_l-debug_dyn-
 thr_dyn-thr_debug_dyn.c_asm.bit
 }}}

 I'm attaching a new patch (to replace the old one) that only undefines the
 symbols after including {{{papi.h}}} as suggested above. This patch
 validates both with and without enabling PAPI support in the runtime.

 I still can't figure out why the problem only occurs while validating, but
 not with a normal papi-enabled build.
