Hello

I'm unable to build darcs-2.12.0, nor 2.12.1, on both Windows 10 and
Windows 7 with the latest Haskel Platform (ghc-8.0.1) using "cabal install
darcs -f-curl".
It appears to originate in Darcs.Util.ByteString which hides the required
types using the preprocessor directives e.g.:

[ 41 of 234] Compiling Darcs.Util.ByteString (
src\Darcs\Util\ByteString.hs, dist\build\Darcs\Util\ByteString.o )
src\Darcs\Util\ByteString.hs:415:22: error:
    Not in scope: type constructor or class `SomeException'


#if mingw32_HOST_OS
#else
import Control.Exception ( catch, SomeException )
#endif

Thanks for the report!

Indeed there has been a confusion in the module you're mentioning, which
now seems obvious. In one patch, Gasneh disabled some imports under
Windows, and in a latter patch, I moved a function that needed the same
imports *under all platforms*.

The fix will be part of a 2.12.3 release soon.

The following patch sent by Guillaume Hoffmann <guillaumh@gmail.com> updated issue issue2510 with
status=resolved;resolvedin=2.12.0 HEAD

* resolve issue2510: import Control.Exception even under Windows

Hello again

This issue is not completely fixed. The one situation I gave was only an
example.
This is the current failure on darcs-2.12.3:

[ 40 of 234] Compiling Darcs.Util.Encoding ( src\Darcs\Util\Encoding.hs,
dist\build\Darcs\Util\Encoding.o )
[ 41 of 234] Compiling Darcs.Util.ByteString (
src\Darcs\Util\ByteString.hs, dist\build\Darcs\Util\ByteString.o )

src\Darcs\Util\ByteString.hs:416:30: error:
    Variable not in scope: performGC :: IO a0

If you don't have Windows machines available I glad to assist by checking
out darcs-2.12 HEAD building and returning the result.

Regards

Joris

Oops * 2

Indeed I only check darcs builds on my personal machine (Ubuntu Linux)
and I don't have a Windows machine available.

Could you send us a patch that fixes building under Windows?

Hello Guillaume

I've only had to change one extra thing on darcs HEAD

hunk ./src/Darcs/Util/ByteString.hs 114
-import System.Mem( performGC )
hunk ./src/Darcs/Util/ByteString.hs 116
+import System.Mem( performGC )

Note however I cannot be sure compilable means correct code!

Regards

Joris
