Building OpenOffice.org with the MinGW compiler

Disclaimer! The build of OpenOffice.org with the MinGW compiler is not supported and fully experimental at this moment!

The following page is a short summary of the required actions to build OpenOffice.org with this compiler.

The only branch with applied MinGW patches is cws_srx645_mingw. You have to checkout the source with cvs, no source archiv is available as this document is written.

Requirements

The build has the same requirements as the W32-tcsh build, but you don't need any Microsoft compiler. (Only the compiler, you need all the rest, e.g. MASM and PSDK.)

A lot of memory

Experiments show that with only 256MB real memory ld is using virtual memory to link the libraries, this takes very long. 512MB real memory and 1.5GB virtual memory are suficient.

A patched MinGW compiler

You can either use the MinGW compiler that comes with Cygwin (gcc -mno-cygwin, alias cygming) or install a MinGW system in addition to you already needed cygwin installation. Choose one of the following two possibilities: cygming

• cygming ( Either this ... )
  

  In addition to the cygwin packages mentioned here for W32-tcsh you need to install:
  
  Only binary
  gcc-mingw
  gcc-mingw-core
  gcc-mingw-g++
  
  With source
  binutils
  mingw-runtime
  w32api
  
  Get and install reimp.exe
  You need reeimp.exe in your path. reimp.exe is used to generate def files from Microsoft import libraries, you can find it in a MinGW installation in the bin directory, or in  mingw-utils-0.3.tar.gz from http://www.mingw.org/download.shtml.
  Only put reimp.exe in the path you are using when building OOo, not all files from that archive.
  

  Patch and rebuild binutils, w32api and mingw-runtime

  The setup program unpacks the source packages to /usr/src. Get the needed resres.c.patch and pseudo-reloc.diff. patches and save them to /usr/src. Now apply the patches:
  
  /usr/src:$ cd /usr/src/binutils-20040312-1
/usr/src/binutils-20040312-1:$ patch -p1 < ../resres.c.patch
/usr/src/binutils-20040312-1:$ patch -p0 < ../pseudo-reloc.diff
  
  
  Rebuild binutils:
  
  /usr/src/binutils-20040312-1:$  ./configure --prefix=/usr \
   --sysconfdir=/etc \
   --libexecdir=/usr/sbin \
   --localstatedir=/var \
   --datadir=/usr/share \
   --mandir=/usr/share/man \
   --infodir=/usr/share/info
/usr/src/binutils-20040312-1:$ make && make install
  
  
  Rebuild  mingw-runtime:
  
  /usr/src/binutils-20040312-1:$ cd ../w32api-2.5-1
/usr/src/w32api-2.5-1:$ ./configure --prefix=/usr \
   --sysconfdir=/etc \
   --libexecdir=/usr/sbin \
   --localstatedir=/var \
   --datadir=/usr/share \
   --mandir=/usr/share/man \
   --infodir=/usr/share/info
/usr/src/w32api-2.5-1:$ make && make install
  
  
  Rebuild w32api:

  /usr/src/w32api-2.5-1:$ cd ..
/usr/src:$ ln -s w32api-2.5-1 w32api
/usr/src:$ cd w32api-2.5-1
/usr/src/w32api-2.5-1:$ cd ../mingw-runtime-3.2-1
/usr/src/mingw-runtime-3.2-1:$ ./configure --prefix=/usr \
   --sysconfdir=/etc \
   --libexecdir=/usr/sbin \
   --localstatedir=/var \
   --datadir=/usr/share \
   --mandir=/usr/share/man \
   --infodir=/usr/share/info
/usr/src/mingw-runtime-3.2-1:$ make && make install
  
  
  That's it. Proceed with the build section.

or

• MinGW ( ... or this! )
  

  You need to install MinGW first, you need:
  MinGW-3.1.0-1.exe,
  gcc-core-3.3.1-20030804-1.tar.gz,
  gcc-g++-3.3.1-20030804-1.tar.gz and
  w32api-2.5.tar.gz

  You have to patch and rebuild binutils and you have to rebuild libmsvcrt.a with the patched binutils. For this you need:
  MSYS-1.0.9.exe,
  msysDTK-1.0.1.exe,
  binutils-2.13.90-20030111-1-src.tar.gz,
  mingw-runtime-3.2-src.tar.gz,
  w32api-2.5-src.tar.gz,
  bison,
  flex.

  Patch the binutils sources with resres.c.patch and pseudo-reloc.diff.

  Hint 1: First rebuild w32api-2.5 and then mingw-runtime-3.2 (This containes libmsvcrt.a)

  Hint 2: To build binutils with MinGW you need bison and flex, but you have to remove them from the path before you start the OOo build.

Build

It is recommended to use an as short as possible path, but the path must include the Platform SDK Bin directory, e.g.:

$ export PATH=/bin:/cygdrive/c/WINNT/system32:/cygdrive/c/WINNT:/cygdrive/c/psdk02_2003/Bin

Now configure, e.g.:

For cygming:
$ ./configure --with-mingwin=yes --with-jdk-home=/cygdrive/c/j2sdk1.4.1_02 \
    --with-ant-home=/cygdrive/c/ant-1.5.3-1 --with-psdk-home=/cygdrive/d/psdk02_2003

or for MinGW:
$ ./configure --with-mingwin=/cygdrive/c/MinGW --with-jdk-home=/cygdrive/c/j2sdk1.4.1_02 \
    --with-ant-home=/cygdrive/c/ant-1.5.3-1 --with-psdk-home=/cygdrive/d/psdk02_2003

Start a tcsh
$ tcsh

Set your environment variables:
$ source winmingw.set

Build dmake
$ ./bootstrap

Rehash your path
$ rehash

Build OOo
$ dmake

And now wait. ...
