Comment(by erikd):
Back to debugging this one. Noticed things like:
{{{
/tmp/ghc16063_0/ghc16063_0.hc:3204:2:
warning: conflicting types for built-in function 'memcpy' [enabled by
default]
}}}
resulting from `compiler/utils/StringBuffer.lhs` which generates
`compiler/utils/StringBuffer.hc` containing:
{{{
ghcFunPtr = ((void * (*)(void *, void *, W_))memcpy);
}}}
however, `memcpy` really has a type:
{{{
void *memcpy(void *dest, const void *src, size_t n);
}}}
with a `const` on the `src` parameter. Pretty sure this is not relevant to
this problem.

Old description:
On Fedora 17 the build fails when attempting to run configure. The
relevant section says:
checking for ncurses.h... yes
checking for setupterm in -lncursesw... no
checking for setupterm in -lncurses... no
checking for setupterm in -lcurses... no
configure: error: in `/home/paj/packages/ghc-7.4.2/libraries/terminfo':
configure: error: curses library not found, so this package cannot be
built
The relevant section from config.log says:
configure~:3285: gcc -o conftest -g -O2 conftest.c -lncursesw 5
/usr/bin/ld: /tmp/cc1CCCaI.o: undefined reference to symbol 'setupterm'
/usr/bin/ld: note: 'setupterm' is defined in DSO /lib64/libtinfo.so.5 so
try adding it to the linker command line
/lib64/libtinfo.so.5: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
I've set the architecture to x86_64 because thats what I run, but I
expect it would happen on other Fedora 17s as well.

I then introduced a symbol (say X) with the same name as an export from one of the versions. Because GHC raises a fatal error on import Foo hiding (X) when X is not exported by Foo, we had no way to have X refer to the local definition -- since if hiding (X) was present, my GHC would error, and if it wasn't, he would get ambiguous reference errors. The alternative would be to list all symbols except X in the import list (there were a good couple hundred). But isn't that what hiding (X) is supposed to be short for anyway? -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7426 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler ___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

The fix should be pretty simple; just edit configure.ac and change AC_CHECK_LIB(ncursesw, setupterm, HaveLibCurses=YES; LibCurses=ncursesw, [AC_CHECK_LIB(ncurses, setupterm, HaveLibCurses=YES; LibCurses=ncurses, [AC_CHECK_LIB(curses, setupterm, HaveLibCurses=YES; LibCurses=curses, HaveLibCurses=NO; LibCurses=not-installed)])]) adding an extra line to try tinfo first, and otherwise fall back to the above curses variants. Unfortunately, I don't have a system with libtinfo to test this on. Can someone please confirm whether that fixes the problem? -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7281#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler ___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

The one in this ticket is fixed by
{{{
commit df39704e33c0f1cf6101daab79c573f354e38a6a

Improve the Prelude doc header; part of #7108
It no longer refers to a particular version of the language standard.
It now includes a note about how it is implicitly imported, and
it looks like the other documentation from the language report
is already included in the haddock docs.
}}}
The others I found are ''comparing'' to H98/H2010, so changing them to
refer to generic standard Haskell may be confusing if the comparison
isn't true for future versions. I've updated the ones I found to refer to
H2010, though.
