Hi all, I'm having some strange issues with cabal install. Some packages installed via `cabal install $foo` are failing for strange (and seemingly unrelated) reasons, but install just fine when I do something like: cabal unpack network cd network cabal configure cabal install Below is some sample output from a failing package: ps168825:~/playground$ cabal install network Resolving dependencies... Configuring network-2.4.1.2... configure: WARNING: unrecognized options: --with-compiler, --with-gcc checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking for gcc... gcc checking whether the C compiler works... yes checking for C compiler default output file name... a.out checking for suffix of executables... checking whether we are cross compiling... configure: error: in `/tmp/network-2.4.1.2-28534/network-2.4.1.2': configure: error: cannot run C compiled programs. If you meant to cross compile, use `--host'. See `config.log' for more details Failed to install network-2.4.1.2 cabal: Error: some packages failed to install: network-2.4.1.2 failed during the configure step. The exception was: ExitFailure 1 ps168825:~/playground 1$ cabal --version cabal-install version 1.16.0.2 using version 1.16.0 of the Cabal library ps168825:~/playground$ ghc --version The Glorious Glasgow Haskell Compilation System, version 7.6.2 /tmp/network-* doesn't exist (which is why I tried unpack, but unfortunately that succeeds). Any thoughts on how I can debug this? Thanks, \t
