Re: [wxhaskell-users] wxHaskell 0.9.4 - wxMac 2.6.1 - GHC 6.4.1 on MacOS 10.4

[Jean B. <jbo...@ac...>]

Hello,

Just to keep you updated: I finally succeeded to build wxHaskell =20
2.6.2 with GHC 6.4.1 on Mac OS 10.4.4.

The "trick" was to add a static C++ standard lib to the libraries =20
used to build "master.o" (see the patch hereafter).
As I'm not an Mac OS X expert, I don't know if this is valid but it =20
works (the linker now warns for duplicate symbols where before it was =20=

complaining that the symbol was undefined).
I compiled and ran the different sample applications. They all went =20
OK except the GLCanvas ones (I do not remember if I compiled wxMac =20
with OpenGL... I will check) and NotebookRight.hs that got an Haskell =20=

typing error.

Hope it helps,
Jean
