Re: GHC/LLDB integration
Excellent, those suggestions are along the lines I was thinking. Thanks for the pointer (no pun intended) re. the C functions in the RTS; I hadn't known of those.

GHC/LLDB integration
Hello all, I've been using LLDB for a few weeks now, initially acquainting myself with its python bindings. It occurred to me early on that they might integrate into GHC's testsuite well, so I began writing a driver. The idea was to encapsulate the launched haskell processes in LLDB and generate more useful debugging information for failed tests (I'd previously been hunting down a few spurious segfaults). However, LLDB is quite immature and currently lacking such capabilities as generating core files, among other things. But while searching for core file generation, I ended up discovering that it is to eventually be implemented as a native plugin. It turns out that the plugin system allows for a lot of extensibility, including language and ABI extension. So I started digging into that and just recently began working on adding a GHRuntime plugin which should allow for demangling of symbols (easy), analysis and description of info tables and call graphs (hard), etc. So before I get too far into it, and because I am not a GHC guru, I'd like to gauge it's ultimate usefulness amongst the community. Given that haskell code goes through several stages of transformation, can more useful information be derived from a debugged executable? Or can more useful debug information be emitted by GHC if it can be interpreted by a purpose-made debugger plugin? If so, what information and functionality would be desirable? Ideas and comments are most welcome. Will ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
Re: GHC build error: cannot satisfy -package ghc-7.1.20110217
Hi Simon, thanks for the reply. Indeed it is reproducible with a maintainer-clean tree and to be sure I even set up a fresh repo. I'm still unclear what the underlying issue is, but I've worked around it by first running `make` until the error, then editing "./ghc/stage1/package-data.mk" to remove the version from the ghc dep, and finally rerunning `make`. The resulting build performs comparably in the test suite to previous builds, so I think it's probably an okay workaround.

Re: GHC build error: cannot satisfy -package ghc-7.1.20110217
Hi all, Not to pester, but this problem has me stumped. All of the dependencies that ghc reports are broken/recursive are reported (with identical versions) by ghc-pkg/cabal as being part of my bootstrap install. Rerunning the offending command with "-package ghc" instead of "-package ghc-7.1.20110217" suppresses the error, but `make` nonetheless insists on rerunning the command with the original arguments. Furthermore, I'm unsure if I'm actually working around a bug or if I'm instead just silencing an error that will slyly retaliate from the shadows. It certainly seems like there's a subtlety with cabal that I don't understand. Any help would be much appreciated.

Then I had to fiddle around with `ghc-pkg` and unfortunately I don't remember exactly what I did, but everything built fine. This time, the error persists and I'm getting nowhere messing with `ghc-pkg` or manual builds of the offending libraries. It's odd that the dependencies are all shown, although ghc-7.1.20110217 is highlighted in blue (not sure what that means): $ ghc-pkg list -v using cache: > /Users/wknop/.ghc/x86_64-darwin-7.1.20110217/package.conf.d/package.cache using cache: > /Library/Frameworks/GHC.framework/Versions/7.1.20110217-x86_64/usr/lib/ghc-7.1.20110217/package.conf.d/package.cache /Library/Frameworks/GHC.framework/Versions/7.1.20110217-x86_64/usr/lib/ghc-7.1.20110217/package.conf.d Cabal-1.11.0 (Cabal-1.11.0-94afda515f19c403e7bc1e64b05e7f80) array-0.3.0.2 (array-0.3.0.2-82b79889a63c9f1c51bec752ba6e74c2) base-4.3.1.0 (base-4.3.1.0-772e705367f0e57fa35bb2732ef27d5f) bin-package-db-0.0.0.0 > (bin-package-db-0.0.0.0-e7fefdd6f3601d1ce130006fe020c686) binary-0.5.0.2 (binary-0.5.0.2-0fc98c736c6f368bb204d82d52e9b985) bytestring-0.9.1.10 > (bytestring-0.9.1.10-9ed25604136f5805a5307d3964bed1a2) containers-0.4.0.0 (containers-0.4.0.0-e65ebc811ae84f909e4426649d5305b6) directory-1.1.0.0 (directory-1.1.0.0-af496658c243f2bddd90748bc896b9cb) extensible-exceptions-0.1.1.2 > (extensible-exceptions-0.1.1.2-d8c5b906654260efd7249f497d17a831) ffi-1.0 (builtin_ffi) filepath-1.2.0.0 (filepath-1.2.0.0-083d27aec2076819a3255aa35e2ce43b) ghc-7.1.20110217 (ghc-7.1.20110217-b77087559342dd20dfcfb258ea8804c4) ghc-prim-0.2.0.0 (ghc-prim-0.2.0.0-dcc46e56b3af1fa9c9fa226ef635850d) haskell2010-1.0.0.0 > (haskell2010-1.0.0.0-5a47cd47ec15d3267342d7569d62be69) haskell98-1.1.0.0 (haskell98-1.1.0.0-ff2f72cc8added329f0e4b03c5cc83e8) hoopl-3.8.6.1 (hoopl-3.8.6.1-9f2c1afa2d4e6e1f5dd2821dfd6b919b) hpc-0.5.0.6 (hpc-0.5.0.6-71c33aa47ae2440fd78a2a606987bc82) integer-gmp-0.2.0.2 > (integer-gmp-0.2.0.2-a1c2a972ace139a643a7e915357c7135) old-locale-1.0.0.2 (old-locale-1.0.0.2-f8974f34bd37bc556cfeca15f8cf9933) old-time-1.0.0.6 (old-time-1.0.0.6-caa2975bbf8e858473e1d88cca412718) pretty-1.0.2.0 (pretty-1.0.2.0-86ef771ce2f9bebde0154187a7714390) process-1.0.1.4 (process-1.0.1.4-8e5c7fd6eb02062956e817290e78052c) random-1.0.0.3 (random-1.0.0.3-ba5d71475c84afcd915bdd0c7896d252) rts-1.0 (builtin_rts) template-haskell-2.5.0.0 > (template-haskell-2.5.0.0-d8450268cce481f1f0f0609421f45d6a) time-1.2.0.3 (time-1.2.0.3-54ba5c61f979a06ebaa014e89cb57800) unix-2.4.1.0 (unix-2.4.1.0-ed4a568ba9e55a6699f0a5637de1eb70) /Users/wknop/.ghc/x86_64-darwin-7.1.20110217/package.conf.d HUnit-1.2.2.3 (HUnit-1.2.2.3-cfbd4873c8348462ffebec9e0e2612ff) QuickCheck-2.4.0.1 (QuickCheck-2.4.0.1-203424cf15ac4e156e45863bdb6c5c3c) ansi-terminal-0.5.5 > (ansi-terminal-0.5.5-572a1d0154fb2632bb4e9431adf0cdb1) ansi-wl-pprint-0.6.3 > (ansi-wl-pprint-0.6.3-875ef2078f6bfbf85f537bf474d4db67) hostname-1.0 (hostname-1.0-fd008e4cbc7e53cd089e95782cd47a3a) mtl-2.0.1.0 (mtl-2.0.1.0-86fd290a44e249d2b21a3e6adc3985a4) regex-base-0.93.2 (regex-base-0.93.2-f611e499723a1c17ae67e04fe4ce3d1e) regex-posix-0.94.4 (regex-posix-0.94.4-9e243c82c4410fcdd8b9c4a9f579cd23) test-framework-0.3.3 > (test-framework-0.3.3-2e089ba99de1028033d51a65ef26cced) test-framework-hunit-0.2.6 > (test-framework-hunit-0.2.6-cd25c078816dfb54d
