Ubuntu, wine, and msys installed into wine

I have not been successful with this. If you want to try, get the automated MinGW installer from Sourceforge. Choose the pre-packaged lists, and then run mingw-get update; mingw-get install msys-base mingw32-base, which should update libtool to version 2.4

Ubuntu, mingw32, wine and Microsoft Visual C++

General setup

It seems that an Openoffice extension for Windows must be compiled with MSVC to be compatible. Here is a way to do this from within Ubuntu. Make sure you have mingw32 and wine installed. Then, get Microsoft Visual (Express) C++ 2010 to work under wine. Installing with vcsetup.exe, or installing Visual Studio is pretty hopeless and an overkill anyway. Instead, try this hack:

  • Get a working installation under Windows (the express version is available for free, and works fine)
  • After booting into Ubuntu, copy cl.exe, c1xx.dll, c1.dll, c2.dll, lib.exe, link.exe, mspdb100.dll and clui.dll from the Windows Visual Express installation to .wine/drive_c/windows/system32/ or some other location in your PATH
  • Copy mt.exe from a Windows SDK installation to .wine/drive_c/windows/system32/ or some other location in your PATH
  • Get winetricks
  • Run winetricks vcrun2010. This will override msvcr100.dll with a Windows native version in the wine configuration

wine cl, wine link and wine lib should now work from a (Unix) terminal

Install the required libraries and include files somewhere (is there a better/standard location?) 

mkdir ~/.wine/drive_c/vc
cp -aR /c/Programme/Microsoft Visual Studio 10/VC/lib/ ~/.wine/drive_c/vc
cp -aR /c/Programme/Microsoft Visual Studio 10/VC/include/ ~/.wine/drive_c/vc
cd ~/.wine/drive_c/vc/include
cp time.h sys
mkdir ~/.wine/drive_c/sdk
cp -aR /c/Programme/Microsoft\ SDKs/Windows/v7.0A/Lib/ ~/.wine/drive_c/sdk
cp -aR /c-ro/Programme/Microsoft\ SDKs/Windows/v7.0A/Include/ ~/.wine/drive_c/sdk

Libtool version 2.4 claims to be able to deal with MSVC so use that version if you can.

Compiling CLN

The latest CLN has patches applied so that it will compile with MSVC

  • Run ./configure CC="wine cl" CXX="wine cl" CCAS="wine cl" LD="wine link" MANIFEST_TOOL="wine mt" LIB="C:/vc/lib;C:/sdk/lib" CPPFLAGS="-MD -DNO_ASM -EHsc -IC:/vc/include -IC:/sdk/include" --host=i586-mingw32msvc
  • Edit libtool and find the two lines containing -OUT. Replace lib with wine lib
  • Run make LIB="C:/vc/lib;C:/sdk/lib"
  • make will stop and complain about missing files cl_asm.obj and cl_asm_GF2.obj
    • change to the src subdirectory
    • Remove cl_asm.lo and cl_asm_GF2.lo
    • Edit the Makefile and find the lines starting with cl_asm.lo: and cl_asm_GF2.lo:
    • Change cl_asm.S and cl_asm_GF2.S to cl_asm_.cc and cl_asm_GF2.cc in these lines (because MSVC doesn't recognize the .S extension). Total of three changes for each.
    • run make cl_asm.lo and make cl_asm_GF2.lo. This should create cl_asm.obj and cl_asm_GF2.obj
  • Run make LIB="C:/vc/lib;C:/sdk/lib" to finish the compile
  • Run make LIB="C:/vc/lib;C:/sdk/lib" check, all tests should pass successfully

Compiling GiNaC

  • Copy libcln.lib into ~/.wine/drive_c/local/lib and the CLN headers into ~/.wine/drive_c/local/include/cln
  • Unpack the source code and run autoreconf -i in the new directory that was created. As of version 1.6.0, the GiNaC MSVC support branch has been merged with the master branch, so you can use that.
  • You can now run ./configure CC="wine cl" CXX="wine cl" LD="wine link" MANIFEST_TOOL="wine mt" LIB="C:/vc/lib;C:/sdk/lib" CPPFLAGS="-MD -DNO_ASM -EHsc -IC:/vc/include -IC:/sdk/include -IC:/local/include" --disable-shared --enable-static --host=i586-mingw32msvc.
  • Edit the libtool created by configure:
    • The line starting with old_archive_cmds must read "wine lib -OUT:\$oldlib\$oldobjs\$old_deplibs". Note that this line occurs twice in the file!
  • In the check (and other subdirectories), when linking fails edit the Makefile and add the following to the command starting with CXXLINK: libcln.lib. This is necessary because the package config file cln.pc is in Unix format and cl cannot find the library as specified there
  • Run make LIB="C:/vc/lib;C:/sdk/lib;C:/local/lib"
  • GiNaC now compiles and all 58 tests pass successfully with make LIB="C:/vc/lib;C:/sdk/lib;C:/local/lib" check
  • If instead you get unhandled exception errors, try moving the definition of lst::info() from the .cpp file to the .h file (and don't ask me why this should make a difference). This only seems to happen when you compile with the -MT flag!

Compiling EQC

Copy libginac.lib into ~/.wine/drive_c/local/lib and the GiNaC headers into ~/.wine/drive_c/local/include/ginac

  • Before starting, be sure to run make distclean and also remove the ccache line in src/Makefile.am (if you want to use ccache then add it to the configure invocation, e.g. CC="ccache wine cl")
  • Run autoreconf -i and ./configure CC="wine cl" CXX="wine cl" LD="wine link" MANIFEST_TOOL="wine mt" LIB="C:/vc/lib;c:/sdk/lib" CPPFLAGS="-DEBUG -MD -EHsc -IC:/vc/include -IC:/sdk/include -IC:/local/include" --host=i586-mingw32msvc.
  • Find two lines with ...lib -OUT... in libtool and change them to ...wine lib -OUT...
  • To get EQC to link successfully, you need to edit the src/Makefile and add the following to the command starting with CXXLINK: libcln.lib libginac.lib.
  • Run make LIB="C:/vc/lib;C:/sdk/lib;C:/local/lib"
  • If you get zillions of multiply-defined symbol errors, try replacing -MD with -MT when running configure (do a distclean before you re-run configure)

Preparing the Office SDK

  • Install Openoffice.org and the Openoffice SDK into wine using the standard Windows installation files. Try to run ~/.wine/drive_c/Program Files/OpenOffice.org 3/program/soffice.exe, if this doesn't start (cannot determine user interface language), then install it into a clean wine.
  • LibreOffice 3.4 requires installing the Visual C++ 2008 runtime libraries with winetricks vcrun2008
  • In the SDK base directory (e.g. ~/.wine/drive_c/Program Files/OpenOffice.org 3/Basis/sdk), put a file config.guess echo wine; exit 0 and make it executable.
  • Edit settings/settings.mk and add a section for wine:

  • Go to sdk/bin and create an executable called cppumaker LD_LIBRARY_PATH=/usr/lib/ure/lib /usr/lib/openoffice/basis3.2/sdk/bin/cppumaker.bin "$@"
  • Go to URE/bin and do ln -s /usr/lib/ure/bin/regmerge ..
  • We probably don't want to use regcomp, but anyway
ln -s /usr/lib/ure/bin/regcomp .
ln -s /usr/lib/ure/bin/regcomp.bin .
  • Install the Office DLLs where wine can find them, but not into ~/.wine/drive_c/windows/system32, because this will confuse the office ("Cannot determine user interface language" error)

Compiling iMath

  • Copy libeqc.lib into ~/.wine/drive_c/local/lib and all the headers from the src subdirectory into ~/.wine/drive_c/local/include/libeqc
  • Edit config.wine BASE= to match your wine installation directory
  • Source the config.wine file
  • Edit src/Makefile.in and change the line starting with PRJ to match your installation (spaces must be escaped - therefore using $(...) doesn't work. Can someone tell me how to get it to work?)
  • Run env autoreconf -i
  • Run ./configure CC="wine cl" CXX="wine cl" LD="wine cl" MANIFEST_TOOL="wine mt" --host=i586-mingw32msvc --build=i686-pc-linux-gnu
  • Change into the source directory
  • Run make. This will produce an error about mt.exe at the end of the process. Just run make again and the extension is created in the iMathout directory
