Ok, it looked good, but then I had to install first the hslogger. Here I
found the same problem, but I had now the scheme, so I began to change.
This it worked fine for configure, but when I try to build, I get:
[6 of 6] Compiling System.Log.Logger ( src/System/Log/Logger.hs,
dist\build/System/Log/Logger.o )
src/System/Log/Logger.hs:348:22:
Illegal signature in pattern: String
Use -XPatternSignatures to permit it
I was thinking that by adding PatternSignatures to the extensions would do
the job, but then I get:
Setup.hs: hslogger.cabal:28: Parse of field 'extensions' failed
Now it looks that we have in the data type Extension from the module
Distribution.Extension no data constructor for this kind of extension
(PatternSignatures). The only thing with patterns is PatternGuards.
I tried also to reformulate a little bit that offending line 348 - there is
something like:
case Map.lookup x lt of
Left (_::String) -> ...
But beeing very late, I gave up after a few tries...
