Hi,
building ghc-6.10.3 under x86 solaris eventually failed with:
Configuring ghc-bin-6.10.3... cabal-bin: At least the following dependencies are missing: haskeline -any gmake[3]: *** [boot.stage.2] Error 1
I think, haskeline is not build because libiconv is missing:
-bash-3.00$ ./Setup configure --prefix=/NONEXISTENT --bindir=/NONEXISTENT --libdir=/NONEXISTENT --libexecdir=/NONEXISTENT --datadir=/NONEXISTENT --docdir=/NONEXISTENT --haddockdir=/NONEXISTENT --htmldir=/NONEXISTENT --with-compiler=/export/local1/home/maeder/haskell/ghc-6.10.3/ghc/stage1-inplace/ghc --with-hc-pkg=/export/local1/home/maeder/haskell/ghc-6.10.3/utils/ghc-pkg/install-inplace/bin/ghc-pkg --libsubdir=$pkgid --with-gcc=gcc --with-ld=/usr/ccs/bin/ld --with-alex=/home/pub-bkb/bin/alex --with-happy=/home/pub-bkb/bin/happy --configure-option='--with-cc=gcc --with-hsc2hs=/export/local1/home/maeder/haskell/ghc-6.10.3/utils/hsc2hs/install-inplace/bin/hsc2hs --haddock-options=--use-contents=../index.html --use-index=../doc-index.html' --enable-library-profiling --enable-split-objs Configuring haskeline-0.6.1.5...
checking whether to use -liconv... Setup: Unable to link against the iconv library.
I wonder how this check for -liconv is generated. I have a file /usr/include/iconv.h but not file /usr/lib/libiconv.*
Haskeline always requires an iconv library when built on POSIX systems; OSes differ on whether that functionality is included as part of libc or whether you need to pass -liconv to gcc. However, my impression was that Solaris is part of the former category, so I'm not sure what's going wrong here. Can you please send the output of running "cabal install haskeline -v3" on Solaris (or, cd into the libraries/haskeline subdirectory and "runghc Setup configure -v3")? (Also, to avoid spamming the mailing list we should probably move this discussion to the haskeline bug tracker: http://trac.haskell.org/haskeline)
Under Linux I've installed successfully http://www.haskell.org/ghc/dist/6.10.3/ghc-6.10.3-i386-unknown-linux-n.tar.b... and I was able to install http://hackage.haskell.org/packages/archive/haskeline/0.6.1.6/haskeline-0.6.... without libiconv!
./Setup configure Configuring haskeline-0.6.1.6... checking whether to use -liconv... not needed.
Right, because on Linux iconv is included in libc.
However, the mere existence of /usr/local/lib/libiconv* files causes configure to use -liconv:
checking whether to use -liconv... using -liconv.
I don't understand why that would happen on Linux; the Setup script prefers not using -liconv if possible (though use of -liconv can be forced with the -flibiconv flag). Can you send (or attach to a ticket) the output of "cabal configure -v3" in the situation you describe? Thanks, -Judah
