loadObj() fails with a Unicode file path on Windows

[guest]

>> cabal install vector

Loading package primitive-0.4.0.1 ... ghc.exe: panic! (the 'impossible' happened)
  (GHC version 7.0.3 for i386-unknown-mingw32):
        loadObj "C:\\Users\\Username\\AppData\\Roaming\\cabal\\primitive-0.4.0.1\\ghc-7.0.3\\HSprimitive-0.4.0.1.o": failed

on Windows 7. Other packages install properly.

Works for me with 7.0.4 on Windows. Could you try a later version and reopen the ticket if you can still reproduce it?

Just try

cabal install agda-executable

I successfully installed agda-executable, but looking at the second error message posted I think I see where the problem might be:

loadObj "C:\\Users\\\1053\1077 \1047\1086\1103\\AppData\\Roaming\\cabal\\primitive-0.4.0.1\\ghc-7.0.4\\HSprimitive-0.4.0.1.o": failed

It looks like your user name is made of Unicode, and we are probably not passing this filename correctly to loadObj.

    Make the RTS linker API use wide-char pathnames on Windows (#5697)
    
    I haven't been able to test whether this works or not due to #5754,
    but at least it doesn't appear to break anything.

just checked 7.0.4 with unicode path in linux - got same error like on windows, but not fatal: "кабал" in path was replaced by ":010;", so binaries got installed in another directory

please check your patch on linux too

[guest]

sorry, of course bug in prev post is not the same as #5697.

wine reports #5697 error as expected.

another bug is that in wine, windows and linux with 7.0.4

cabal changes unicode characters in install path to some other, probably ASCII, like in prev post.

possibly this is related with #5754

[simonmar]

The bug in this ticket is now fixed. I've tested it by hand, but testing it automatically is ridiculously hard due to code page problems (see #5754) so I'm giving up.
