[Hugs] #63: hugs cabal incomplete

#63: hugs cabal incomplete --------------------------------+------------------------------------------- Reporter: jvlask(a)hotmail.com | Owner: nobody Type: defect | Status: new Priority: major | Milestone: Component: hugs | Version: 200609 Keywords: cabal | --------------------------------+------------------------------------------- Two things 1) hugs cabal does not take any notice of additional C files specified in the cabal config 2) hugs cabal passes libraries using mingw conventions and does not support a build process using msvc. i.e. libraries passed as -lodbc 3) I used to be able to generate the C stub for seporate compilation with the following command ffihugs -98 +G -Pbuild: +L"-D_WIN32_" +L"-Dmingw32_HOST_OS" +L"-I./HSQL" +L"./ODBC/Database/HSQL/HsODBC.o" +L"odbc32.lib" +L"-I./ODBC/Database/HSQL" $< this worked fine and achieved what was desired:- generating a C file compiling and specifying additional link libraries and include path. this can be done with the new hugs like so ffihugs -98 $< -D_WIN32_ -Dmingw32_HOST_OS -I./HSQL ./ODBC/Database/HSQL/HsODBC.o odbc32.lib -I./ODBC/Database/HSQL The current cabal setup for hugs does not support the generation/specification of such a command, so I am left with no option but to use a hybrid of cabal and make files ... very unsatisfactory. 4) you should really think about linking hugs against the multithreaded library /MD by default many external gnu etc libraries (actually all that I have come accross) link against msvcrt.lib. Having two different rtl being called can cause problems. -- Ticket URL: <http://hackage.haskell.org/trac/hugs/ticket/63> Hugs <http://www.haskell.org/hugs/> Hugs 98, an interpreter for Haskell

[Hugs] #44: Hugs does not provide version numbers for installed packages

#44: Hugs does not provide version numbers for installed packages -------------------------+-------------------------------------------------- Reporter: briansmith | Owner: nobody Type: enhancement | Status: new Priority: major | Milestone: Component: hugs | Version: 200609 Keywords: | -------------------------+-------------------------------------------------- After installing WinHugs, we can inspect the "packages" subdirectory to see what packages are installed. But, there is no way to tell what version of each package is installed. I know that Hugs does not provide a versioning mechanism for packages like GHC does, but it would be very helpful it it at least included a "version" file in each directory that contained the version number from the Cabal file. -- Ticket URL: <http://hackage.haskell.org/trac/hugs/ticket/44> Hugs <http://www.haskell.org/hugs/> Hugs 98, an interpreter for Haskell
