Weird symbol prevents GHCi from loading my package.
by Axel Simon 13 Feb '02

Hi, I built quite a big library and turned it into a package. It works fine if use ghc -package gtk2 Blah.hs to compile things. But when I convert all the libraries to object files as described in the documentation, GHCi refuses to load the whole machinery: ~/source/mogul/fpDemo:$ ghci -package gtk2 Arabic.hs ___ ___ _ / _ \ /\ /\/ __(_) / /_\// /_/ / / | | GHC Interactive, version 5.02.2, for Haskell 98. / /_\\/ __ / /___| | http://www.haskell.org/ghc/ \____/\/ /_/\____/|_| Type :? for help. Loading package std ... linking ... done. Loading package lang ... linking ... done. Loading package gtk2 ... GHCi runtime linker: fatal error: I found a duplicate definition for symbol gcc2_compiled. whilst processing object file /home/as49/local/lib/gtk2hs/gtk2hs.o This could be caused by: * Loading two different object files which export the same symbol * Specifying the same object file twice on the GHCi command line * An incorrect `package.conf' entry, causing some object to be loaded twice. GHCi cannot safely continue in this situation. Exiting now. Sorry. The symbol obviously has nothing to do with GHCi, but I don't have a clue how it got there and it probably does not matter as long as I don't use GHCi. Does anybody know where it comes from? My library consists of a huge bunch of modules, most of them having C calls and callbacks. Thanks for hints, Axel. P.S.: Output from ~/source/mogul/fpDemo:$ ghc-pkg -s gtk2 Package {name = "gtk2", import_dirs = ["/home/as49/local/lib/gtk2hs/hi"], source_dirs = [], library_dirs = ["/home/as49/local/lib", "/home/as49/local/lib/gtk2hs", "/usr/X11R6/lib", "/usr/local/lib"], hs_libraries = ["gtk2hs"], extra_libraries = ["X11", "Xext", "atk", "gdk-x11-1.3", "gdk_pixbuf-1.3", "glib-1.3", "gmodule-1.3", "gobject-1.3", "gtk-x11-1.3", "iconv", "intl", "m", "pango", "pangox"], include_dirs = ["/home/as49/local/include/atk-1.0", "/home/as49/local/include/glib-2.0", "/home/as49/local/include/gtk-2.0", "/home/as49/local/include/pango-1.0", "/home/as49/local/lib/glib-2.0/include", "/home/as49/local/lib/gtk-2.0/include", "/home/as49/local/lib/gtk2hs/hi", "/usr/X11R6/include"], c_includes = ["Container_stub.h", "General_stub.h", "Signal_stub.h", "TreeSelection_stub.h", "gtk/gtk.h"], package_deps = ["lang"], extra_ghc_opts = ["-fglasgow-exts"], extra_cc_opts = [], extra_ld_opts = ["-u TreeSelection_dwzw", "-u TreeSelection_dwzx"]}

problem with source 5.03
by Hal Daume III 13 Feb '02

13 Feb '02

There seems to be a problem with the source tar.bz2 distribution of the 5.03 snapshot. The web page claims it's 5.3M, but the actualy file is only 4117517 bytes and doesn't untar properly: x ghc-5.03.20020204/ghc/InstallShield/Setup Files/Compressed Files, 0 bytes, 0 tape blocks x ghc-5.03.20020204/ghc/InstallShield/Setup Files/Compressed Files/Language Independent, 0 bytes, 0 tape blocks tar: directory checksum error I was able to grab a CVS image, but someone should probably fix this. - Hal -- Hal Daume III "Computer science is no more about computers | hdaume(a)isi.edu than astronomy is about telescopes." -Dijkstra | www.isi.edu/~hdaume

CVS Build problem

Hi, I just checked a fresh copy of ghc + hslibs out of CVS, and tried doing a vanilla build. It fell over doing "make boot" in hslibs. Here are the last few make messages: ------------------------------------------------------------------------ ===fptools== Finished making `all' in includes utils driver docs compiler rts ...

RE: Edison library
by David Feuer 12 Feb '02

12 Feb '02

I'm sorry if I was confusing, but by "efficient" I meant "something other than unbalanced trees". Since the library provides a fairly large variety of heaps, it is surprising that it only provides a toy implementation of sets. It is particularly surprising because I know that Okasaki has written about balanced tree implementations before (e.g. in Purely Functional Data Structures).

Anyone know if Okasaki plans to expand Edison to include efficient sets and/or other non-heap collections? It looks like the library hasn't changed for 2 years... David Feuer

Installing binary rpm on Redhat 7.1 - libreadline issue
by Erik Williamson 11 Feb '02

11 Feb '02

Hi All! Has anyone else had this problem? I've got readline & readline-devel installed. Given, I'm trying to install an RPM build on a 7.2 sytem onto a 7.1, but... Is it something to do with my (nonexistant) LIBRARY_PATH environment? [erik@proto rpms]$ rpm -Uvh ghc-5.02.2-rh72-1.i386.rpm error: failed dependencies: libreadline.so.4 is needed by ghc-5.02.2-1 [erik@proto rpms]$ rpm -qa | grep readline readline-devel-4.1-9 readline-4.1-9 [erik@proto rpms]$ rpm -ql readline /usr/lib/libhistory.so.4 /usr/lib/libhistory.so.4.1 /usr/lib/libreadline.so.4 /usr/lib/libreadline.so.4.1 Thanks for any insight!
