#4147: 'withFilePath' not in scope, windows build, using base 4.1.0.0
---------------------------------+------------------------------------------
Reporter: lcasburn | Owner:
Type: bug | Status: new
Priority: normal | Component: libraries/directory
Version: 6.10.4 | Keywords:
Os: Windows | Testcase:
Architecture: Unknown/Multiple | Failure: Compile-time crash
---------------------------------+------------------------------------------
The cabal file indicates that directory>=1.0.1.0 should install correctly
with base>=4.1. However, running in windows, the {{{System.Directory}}}
module expects to use the function {{{withFilePath}}} in its functions,
but I have not seen it defined until base 4.2:
{{{
copyPermissions :: FilePath -> FilePath -> IO ()
copyPermissions source dest = do
#ifdef mingw32_HOST_OS
allocaBytes sizeof_stat $ \ p_stat -> do
withFilePath source $ \p_source -> do
withFilePath dest $ \p_dest -> do
throwErrnoIfMinus1_ "copyPermissions" $ c_stat p_source p_stat
mode <- st_mode p_stat
throwErrnoIfMinus1_ "copyPermissions" $ c_wchmod p_dest mode
#else
stat <- Posix.getFileStatus source
let mode = Posix.fileMode stat
Posix.setFileMode dest mode
#endif
}}}
The compilation fails with:
{{{
[1 of 1] Compiling System.Directory ( System\Directory.hs,
dist\build\System\Directory.o )
System\Directory.hs:179:2: Not in scope: `withFilePath'

System\Directory.hs:951:6: Not in scope: `withFilePath'

}}}
I have attached the cabal build output to this ticket.
