Description Robin Green 2010-03-31 13:59:29 UTC 
Description of problem:
ghci (from package ghc) tries to dynamically load the file /usr/lib/libncursesw.so when compiling a certain package, and fails with the error message:

Loading package terminfo-0.3.1.1 ... <command line>: can't load .so/.DLL for: ncursesw (/usr/lib/libncursesw.so: file too short)

It turns out that this file is a plain text file. I thought .so files were supposed to be binaries?

Version-Release number of selected component (if applicable):
ncurses-devel-5.7-7.20100130.fc13.i686
Comment 1 Miroslav Lichvar 2010-03-31 14:34:50 UTC 
The libncursesw.so symlink was replaced recently with a linker script to help packages link correctly with libncurses since the linker is now using --no-add-needed by default.

Going back would probably mean patching tens of packages.

Could be ghci modified to try to load libncursesw.so.5 instead?
Comment 2 Robin Green 2010-03-31 18:12:57 UTC 
I discovered ghci has been fixed upstream to do the right thing. Thanks - sorry for the bogus bug report.
