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++ 2008 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, msdp80.dll and clui.dll to .wine/drive_c/windows/system32/ or some other location in your PATH
  • Get winetricks
  • Run winetricks vcrun2008
  • Override msvcr90.dll with 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/cl
mkdir ~/.wine/drive_c/cl/VC
cp -aR /c/Programme/Microsoft Visual Studio 9/VC/lib/ ~/.wine/drive_c/cl/VC
cp -aR mvs/VC/include/ ~/.wine/drive_c/cl/VC
cd .wine/drive_c/cl/VC/include/
cp time.h sys
mkdir ~/.wine/drive_c/cl/SDK
cp -aR /c/Programme/Microsoft\ SDKs/Windows/v6.0A/Lib/ ~/.wine/drive_c/cl/SDK
cp -aR /c-ro/Programme/Microsoft\ SDKs/Windows/v6.0A/Include/ ~/.wine/drive_c/cl/SDK

Libtool version 2.4 claims to be able to deal with MSVC. I have not been able to confirm this, but if you want to try, you can download libtool 2.4 source, run configure, make and make install (which will install into /usr/local/...). Then, to use it e.g. in compiling GiNaC, go to the main GiNaC directory and run env LIBTOOLIZE=/usr/local/bin/libtoolize autoreconf -i before executing configure

Compiling CLN

CLN still needs a lot of fixes to compile with MSVC.

Compiling GiNaC

Copy libcln.lib into ~/.wine/drive_c/cl/lib and the CLN headers into ~/.wine/drive_c/cl/include/cln

Get the source code from GiNaC MSVC support branch using the download button on the web page.

You can now run ./configure CC="wine cl" CXX="wine cl" LD="wine link" LIBTOOL=/usr/local/bin/libtool CPPFLAGS="-DEBUG -MD -EHsc -IC:/cl/VC/include -IC:/cl/SDK/Include -IC:/cl/include" LIB="C:/cl/VC/lib;C:/cl/SDK/lib;C:/cl/lib" --host=i586-mingw32msvc (assuming that you are using the libtool installed into /usr/local). There are still a lot of libtool issues, though, which need to be hacked by editing libtool:

  • 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!
  • The line starting with LTCFLAGS must read LTCFLAGS="-g -IC:/cl/VC/include -IC:/cl/SDK/Include"
  • Find the line containing $cwrapper $cwrappersource and add C:/cl/VC/lib/libcmt.lib C:/cl/VC/lib/oldnames.lib C:/cl/SDK/lib/Kernel32.lib to the end of it
  • In the check (and other subdirectories), when linking fails edit the Makefile and add the following to the command starting with CXXLINK: C:/cl/VC/lib/msvcrt.lib C:/cl/VC/lib/msvcprt.lib C:/cl/VC/lib/oldnames.lib C:/cl/SDK/lib/Kernel32.lib C:/cl/SDK/lib/Uuid.lib C:/cl/lib/libcln.lib
  • After compilation, the wrapper created in the source directory does not work, but the .exe created in .libs does. Do cp .libs/* . before running make check again.

After hacking away the libtool problems, GiNaC compiles and all 58 tests pass successfully.

Compiling EQC

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

Before starting, remove the ccache line in src/Makefile.am. Then, run env LIBTOOLIZE=/usr/local/bin/libtoolize autoreconf -i and ./configure CC="wine cl" CXX="wine cl" LD="wine link" LIB="C:/cl/VC/lib;c:/cl/SDK/lib" CPPFLAGS="-DEBUG -MD -EHsc -IC:/cl/VC/include -IC:/cl/SDK/include -IC:/cl/include" --host=i586-mingw32msvc. To get EQC to link successfully, you need to edit the Makefile and add the following to the command starting with CXXLINK C:/cl/VC/lib/msvcrt.lib C:/cl/VC/lib/msvcprt.lib C:/cl/VC/lib/oldnames.lib C:/cl/SDK/lib/Kernel32.lib C:/cl/SDK/lib/Uuid.lib C:/cl/lib/libcln.lib C:/cl/lib/libginac.lib. If the Makefile has no such line, edit libeqc.la instead and change the line reading dependency_libs to have these libraries (instead of the ones listed).

Preparing the OOo SDK

  • Install Openoffice.org and the Openoffice SDK into wine using the standard Windows installation files.
  • In the SDK base directory (e.g. ~/.wine/drive_c/Program Files/OpenOffice.org 3/Basis/sdk), put a file config.guessecho wine; exit 0.
  • Edit settings/settings.mk and add a section for wine:

  • Go to sdk/bin and create an executable 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 OOo DLLs where wine can find them, e.g. cp -i "~/.wine/drive_c/Program Files/OpenOffice.org 3/URE/bin/"*.dll ~/.wine/drive_c/windows/system32
  • Before starting work, source this file (csh version)

Compiling iMath

Copy libeqc.lib into ~/.wine/drive_c/cl/lib and the headers into ~/.wine/drive_c/cl/include/libeqc.

Copy autosprintf.h from a MinGW installation into ~/.wine/drive_c/cl/include

./configure CC="wine cl" CXX="wine cl" LD="wine link" LIB="C:/cl/VC/lib;c:/cl/SDK/lib" CPPFLAGS="-DEBUG -MD -EHsc -IC:/cl/VC/include -IC:/cl/SDK/include -IC:/cl/include" --host=i586-mingw32msvc --build=i686-pc-linux-gnu

Edit src/Makefile and chnage the line starting with PRJ to the value of OO_SDK_HOME with spaces escaped (if there are no spaces in the path then you are fine).
