Thanks for the link. I don't see the Haskell connection - it's
If this is the same problem, then I don't see how to proceed.
In their case, it was two modules within their own project
that were linking to the two different copies of iconv.
They just needed to get the two modules to agree.
But in our case, MacPorts readline is linking to
MacPorts iconv as it should, and HP base is linking to
native iconv as it should.
So i've abandoned MacPorts readline, and I'm trying
to build GNU readline manually. So far, I haven't been
able to get this to work either. I have a number of
What version of GNU readline should I use? The current
version is 6.1, but the Haskell readline package doesn't
seem to support that. The highest version mentioned in
HsReadlineConfig.h.in is 5.0. I tried 6.1 anyway, but
unsurprisingly, Haskell readline didn't recognize it.
What version should I use?
Older versions of readline stubbornly refuse to build
shared libraries on Snow Leopard. The make fails with:
only allowed with -dynamiclib
But I can't figure out how to pass the flag it wants.
When I put it in CFLAGS or LDFLAGS, configure
fails right at the start with
configure: error: cannot run C compiled programs.
Also - should I use -m32 or not when building
Could be that the real solution is to go back to Judah's
GNUreadline.framework idea, and to arrange for the
readline package to use it on the Mac. The only difference
is that now the framework is not required for GHC as
it was in the past, only for the readline package.
It's clear that it is currently at least extremely difficult
and non-intuitive, if not impossible, to use the readline
package on Snow Leopard. That needs to be fixed.
