[Haskell-cafe] pcre-light install fails with undefined reference to _impure_ptr

[Patrick Caldon]

Not seen this one before.

I'm trying to install pcre-light with WinXP 64, Cygwin 1.7.1, Cabal
0.8.0, and ghc 6.12.1. Trying to reinstall "base" with cabal fails as
well with an internal error (see below), but I'm assuming that's
quasi-intentional/unsupported feature or something.

Any ideas? My ultimate goal is to install ghc-core to help track down
some performance problems I'm having.

Thanks,
Patrick.

Hi Patrick

I think the problem is because PCRE uses c++, and doing a quick web
search shows that _impure_ptr link errors are a recurrent problem for
the PCRE binding with GHC. Funnily enough 6.10.3 worked fine - I
posted to the list a month or two ago with instructions how to do it,
but 6.12.1 fails for me in the same was as it fails for you.

I'll try next with MinGW to see if that works...

Best wishes

Aye, it builds fine under MinGW.

I built and installed PCRE (c & c++ library) from the source
(./configure, make, make install), though I think there is a package
available on the msys / MinGW repository.

Then I installed pcre-light via runhaskell Setup ... rather than cabal install.

The source build of the C library puts the headers in
C:\msys\1.0\local\include and the libs in C:\msys\1.0\local\lib so the
runhaskell commands were (remembering that runhaskell on Windows takes
directory names with double win-slash):

$ runhaskell Setup.lhs configure
--extra-lib-dirs=C:\\msys\\1.0\\local\\lib
--extra-include-dirs=C:\\msys\\1.0\\local\\include

$ runhaskell Setup.lhs build

$ runhaskell Setup.lhs install

Best wishes

Stephen

Thanks for your help, I'll get a MinGW setup together.

Cheers, Patrick.

For the record...

The regex-posix package also failed to build for me with GHC 6.12.1 on
Windows with Cygwin due to >> undefined reference to `_impure_ptr' <<
errors.

Again this builds fine with MinGW once you have the GNU regex library
installed (its not installed as a default MSys package). With a
runhaskell Setup.hs ... install you need to set the
extra-include-dirs to pick up regex.h and the extra-lib-dir to pick up
libregex.a

I got it to work using the package from the msys repository, but I had
to remove "-viaC" from the cabal file.

Greetings,
