win32 native build

Rate this Message:
Hello all,
I march 2008 there were some mailings about letting ORBit work with MS compilers. What is the current state on this? Is there something that still needs to be done ? I want to port some existing code to work on win32. I already downloaded the ORBit2-dev_2.4.16-1_win32.zip from the gnome ftp site, but there were no lib files included. kind regards, Bart _______________________________________________ orbit-list mailing list orbit-list@... http://mail.gnome.org/mailman/listinfo/orbit-list |

You can produce one for instance like this: download http://tml.pp.fi/pexports-0.44.zip, unpack, put pexports.exe somewhere in %PATH% . pexports also comes with mingw. cd foo\lib pexports ..\bin\libORBit-2-0.dll >ORBit-2.def lib -def:ORBit-2.def -machine:x86 -out:ORBit-2.lib where lib is lib.exe that comes with MSVC. You can also use link -dump -exports instead of pexports, but then you will have to edit the output file into .def syntax, and the exported variables won't be marked with the DATA keyword, which probably is very relevant for the produced import library to be useful with MSVC. Note that I have never used ORBit2 with MSVC-built code myself, I only told above how to produce an MS import library. --tml _______________________________________________ orbit-list mailing list orbit-list@... http://mail.gnome.org/mailman/listinfo/orbit-list |

So look for pexports.exe from mingw instead. --tml _______________________________________________ orbit-list mailing list orbit-list@... http://mail.gnome.org/mailman/listinfo/orbit-list |

Thank you.
It seems to work, at least for function calls. The data structures remain still unresolved. In the def file for example I see this: TC_CORBA_short_struct DATA TC_CORBA_string_struct DATA TC_CORBA_unsigned_long_long_struct DATA TC_CORBA_unsigned_long_struct DATA TC_CORBA_unsigned_short_struct DATA My linkage gives unresolved for this (DATA) symbols. The solution was that I just needed to remove "DATA" before building the lib file. But my little test program links now. kind regards, Bart Tor Lillqvist wrote: >> I already downloaded the >> ORBit2-dev_2.4.16-1_win32.zip from the gnome ftp site, but there were no lib >> files included. >> > > You can produce one for instance like this: > > download http://tml.pp.fi/pexports-0.44.zip, unpack, put pexports.exe > somewhere in %PATH% . pexports also comes with mingw. > cd foo\lib > pexports ..\bin\libORBit-2-0.dll >ORBit-2.def > lib -def:ORBit-2.def -machine:x86 -out:ORBit-2.lib > > where lib is lib.exe that comes with MSVC. > > You can also use link -dump -exports instead of pexports, but then you > will have to edit the output file into .def syntax, and the exported > variables won't be marked with the DATA keyword, which probably is > very relevant for the produced import library to be useful with MSVC. > > Note that I have never used ORBit2 with MSVC-built code myself, I only > told above how to produce an MS import library. > > --tml > > _______________________________________________ orbit-list mailing list orbit-list@... http://mail.gnome.org/mailman/listinfo/orbit-list |

I think that must be because the corresponding declarations in the headers don't have the __declspec(dllimport) attributes. gcc can manage without, MSVC can't. > My linkage gives unresolved for this (DATA) symbols.

But it is probable that actual use of these variables without MSVC knowing that they are actually imported from a DLL produces bogus results or even crashes? Does the program actually work? --tml _______________________________________________ orbit-list mailing list orbit-list@... http://mail.gnome.org/mailman/listinfo/orbit-list |

If you want to play with that, you may want to take a look at http://bugzilla.gnome.org/show_bug.cgi?id=537328. It's been a few months since I touched that code, but it worked for me with MSVC. (I have my own hacked together makefiles to compile orbit on Win32, I could send them to you but they're not pretty.) -- Marcelo Vanzin mmvgroups@...
