Yo ho! I just installed ghc-6.10.4 over my 6.10.3. Now 'cabal install lhs2tex' works. Phew! On Mon, Jul 27, 2009 at 11:44 AM, Conal Elliott wrote:

Thanks, Don.

Trying your first suggestion, I get the same result for the first and third method, and a ghc panic on cat_evals for the second method. All happening in ghc-6.10.3 installed via the Haskell Platform last week on OS X.

bash-3.2$ cabal install lhs2tex --constraint='base<4' Resolving dependencies... [1 of 1] Compiling Main ( /tmp/lhs2tex-1.1424460/lhs2tex-1.14/Setup.hs, /tmp/lhs2tex-1.1424460/lhs2tex-1.14/dist/setup/Main.o ) Linking /tmp/lhs2tex-1.1424460/lhs2tex-1.14/dist/setup/setup ... Configuring lhs2tex-1.14... cabal: Error: some packages failed to install: lhs2tex-1.14 failed during the configure step. The exception was: exit: ExitFailure 11

Still fishy about compiling Main first.

Now I'll edit add the '< 4' constraint on base, giving the same result:

bash-3.2$ dirs ~/cabal bash-3.2$ cabal unpack lhs2tex Unpacking lhs2tex-1.14... bash-3.2$ cd lhs2tex-1.14

[lhs2tex.cabal edit happens here]

bash-3.2$ cabal install Resolving dependencies... [1 of 1] Compiling Main ( Setup.hs, dist/setup/Main.o ) Linking ./dist/setup/setup ... Configuring lhs2tex-1.14... cabal: Error: some packages failed to install: lhs2tex-1.14 failed during the configure step. The exception was: exit: ExitFailure 11

Note that on linux, the package compiles without changing the base constraint. I don't know how.

Finally, use explicit ./configure & make:

Note that the the first module to be compiled is Main. On my linux machine, Main is the *last* of several modules to be compiled.

Here's my failure log: http://moonpatio.com/fastcgi/hpaste.fcgi/view?id=3096# a3096 .

If instead I use ./configure and make, i get errors due to use of the

Suggestions greatly appreciated!

Via cabal:

--constraint='base<4'

or replace Control.Exception with Control.OldException

or add 'base < 4' to the depends in the .cabal file.
