#98: cabal assumes -x option for linking ---------------------------------------+------------------------------------ Reporter: Christian.Maeder(a)dfki.de | Owner: ijones Type: defect | Status: closed Priority: normal | Milestone: Cabal-1.2 Component: Cabal library | Version: 1.2.0 Severity: normal | Resolution: fixed Keywords: | Difficulty: easy (<4 hours) Ghcversion: 6.6 | Platform: Other Unix ---------------------------------------+------------------------------------ Comment (by duncan): Replying to [comment:2 guest]: > Furthermore the generated file libraries/base/GNUMakefile contained "`xargs -s 30000`" which is too big for Solaris (the maximal value is 2048) I'd really like to get this increased. 2048 is ridiculously low for most platforms. We end up doing multiple ar and ld calls even for ordinary sized Haskell projects without even using split-objs. If people use split- objs we'll end up making 100's of ar/ld calls for larger libs. According to POSIX.1-2001 the minimum value for ARG_MAX is _POSIX_ARG_MAX which is 4096. So surely even older versions of Solaris must have supported at least 4096? I used the following C program to test on Solaris 9 and I discovered the value is 1048320. {{{ #include <stdio.h> #include <unistd.h> #include <limits.h> int main () { printf("ARG_MAX == %d, sysconf(_SC_ARG_MAX) == %ld\n", ARG_MAX, sysconf(_SC_ARG_MAX)); return 0; } }}} On posix systems we could test dynamically using `System.Posix.Unistd.getSysVar ArgumentLimit` though it's a pain because we'd have to use cpp and add a conditional dependency on the unix package. Christian, what version of Solaris are you using and what does the above C program report for you? -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/98#comment:15> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #254: Misleading documentation on comments in .cabal

#254: Misleading documentation on comments in .cabal ----------------------------------+----------------------------------------- Reporter: guest | Owner: Type: defect | Status: new Priority: low | Milestone: Component: misc | Version: 1.2.3.0 Severity: minor | Keywords: Difficulty: very easy (<1 hour) | Ghcversion: 6.8.2 Platform: | ----------------------------------+----------------------------------------- in http://www.haskell.org/cabal/release/latest/doc/users-guide/x30.html #pkg-descr we read, "In the package description file, lines beginning with "--" are treated as comments and ignored." This isn't right, since it's actually -- after any amount of whitespace; you can indent as you please, and cabal will still treat it as a comment and not try to interpret your crazy English stuff. It's a bit misleading. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/254> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

#120: misleading error message from cabal when versions differ -----------------------------+---------------------------------------------- Reporter: igloo(a)earth.li | Owner: Type: defect | Status: closed Priority: normal | Milestone: Component: Cabal library | Version: 1.1.6 Severity: normal | Resolution: fixed Keywords: | Difficulty: easy (<4 hours) Ghcversion: 6.6 | Platform: Linux -----------------------------+---------------------------------------------- Changes (by duncan): * status: new => closed * resolution: => fixed Comment: It now adds a header to the file and checks it again when reading. The header is a line like: {{{ Saved package config for foo-1.0 written by Cabal-1.3.7 using ghc-6.8 }}} It checks this header when reading back the config. If the Cabal versions do not match you'll get this error: {{{ cabal: You need to re-run the 'configure' command. The version of Cabal being used has changed (was Cabal-1.3.6, now Cabal-1.3.7). }}} If additionally the compiler versions do not match then you get: {{{ cabal: You need to re-run the 'configure' command. The version of Cabal being used has changed (was Cabal-1.3.6, now Cabal-1.3.7). Additionally the compiler is different (was ghc-6.8, now ghc-6.9) which is probably the cause of the problem. }}} Of course it does not help for older Cabal versions which lacked this check but it's the best we can do and should help in future. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/120#comment:2> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
