Dependencies required for building with MinGW

Compiling your own copy of GRASS is greatly simplified by using the OSGeo4W directory structure to install most dependencies and downloading the rest from a few other locations. Follow the steps below to set up the build environment for GRASS.

Install the OSGeo4W directory structure

OSGeo4W has several of the required dependencies for compiling GRASS:

Download the OSGeo4W installer from here.

Run the installer.

Select Advanced Install, and Next.

Set the install directory to c:\OSGeo4W (other directories or fine if there are no spaces in the path but make sure to adjust the instructions below (?))

Select grass from the desktop section (this is a binary but we'll compile from source later).

Also select:

Commandline_Utilities
- avce00
- gpsbabel

Libs:
- fftw-devel
- freetype-devel
- freetype-devel-mingw
- gsl-libs
- gsl-devel
- libpng-devel
- libpng-devel-mingw
- libtiff-devel
- libxdr
- mingw-libs (contains mingw-style libraries for VC build binaries and depends on gdal, libpq, libjpeg-devel, sqlite3, libtiff, zlib, proj)
- pdcurses-devel
- tcltk-devel
- zlib-devel

Click next, the selected packages and their required subpackages will be downloaded and installed automatically.

Install the environment for compilation (MingW)

Run msys (there should be an icon on the desktop)

type:
```
 mkdir /c/osgeo4w/apps/msys/osgeo4w
```
Copy c:\osgeo4w\apps\msys\etc\fstab.sample to c:\osgeo4w\apps\msys\etc\fstab (without .sample)

Open c:\osgeo4w\apps\msys\etc\fstab

At line 16, change:

c:/mingw		/mingw
c:/ActiveState/perl	/perl

To:

c:/osgeo4w/	/osgeo4w

Download the MinGW packages:
- bin-utils from here
- gcc-core from here
- gcc-g++ from here
- mingw32-make from here
- mingw-runtime from here
- mingw-utils from here
- w32api from here

Unpack all to c:\osgeo4w

Download an updated make from here (required for grass-7.0.svn)

Unpack to c:\osgeo4w\apps\msys

Pre-built Binaries

Download:

bison from here
bison-deps from here
flex from here
gettext-bin from here
gettext-lib from here
libintl-bin from here
libintl-lib from here
regex from here

Unpack all to c:\osgeo4w

Compiling and Installing GRASS (6.4.0)

Download the latest GRASS 6.4.0 source code from here.

Unpack to c:\osgeo4w\usr\src

Open c:\osgeo4w\usr\src\grass64\mswindows\osgeo4w\package.sh and at line 12:

Change:

--with-libs="/c/OSGeo4W/lib /c/MinGW/lib" \
--with-includes="/c/OSGeo4W/include /c/MinGW/include" \

to:

--with-libs=/c/OSGeo4W/lib \
--with-includes=/c/OSGeo4W/include \

To compile, type in MSYS console:

export PATH="/osgeo4w/bin:$PATH"
cd /osgeo4w/usr/src/grass-6.4xxx (change to dir of the version you downloaded)
./mswindows/osgeo4w/package.sh

When finished, you should have the following compilation log (c:\osgeo4w\usr\src\grass-6.4xxx\error.log):

In case of errors please change into the directory with error and run 'make'.
If you get multiple errors, you need to deal with them in the order they
appear in the error log. If you get an error building a library, you will
also get errors from anything which uses the library.

Finished compilation: Mon Feb 16 10:11:17 GMT 2009
make: *** [default] Error 1

Currently r.li.* cannot be compiled on Windows, but grass will run fine without them.

Because of these errors in the install script stops. To finish it type:
```
make install
```

Now GRASS should be installed in c:\osgeo4w\apps\grass-6.4.0\

Usage

To start grass use the icon on the desktop.

OR, if you want to be able to use the command line from within grass, you'll need a different start-up file.

Open C:\OSGeo4W\apps\grass\bin\grass64 and at line 24 add:

# Set the PYTHONPATH
PYTHONPATH="$GISBASE/etc/python:$PYTHONPATH"

To start grass, type in MSYS console:
```
/osgeo4w/apps/grass/bin/grass64
```

Or to use the new wxpython GUI:

/osgeo4w/apps/grass/bin/grass64 -wxpython

Compiling and Installing Development Versions of GRASS

Optional Installation of Subversion

The GRASS source tree is stored in an online repository called Subversion. Rather than downloading source trees from the website, subversion lets you keep up to date, and manage your modifications, with simply commands. For more see Working with SVN.

Download Collabnet Subversion Command-Line Client (1.6) from here. (You'll have to register on Collabnet)

Run the installer and install to somewhere without paths(?) such as c:/Subversion or c:/Programs/Subversion

Open c:\osgeo4w\etc\ini\msys.bat and at line 1 add the path to your subversion folder, eg. change:
```
PATH %PATH%;%OSGEO4W_ROOT%\apps\msys\bin
```

To:

PATH %PATH%;%OSGEO4W_ROOT%\apps\msys\bin;/c/Programs/Subversion

Grass-6.5.svn (develbranch_6)

Download the grass-6.5.svn source tree with:

subversion (also see here

cd /osgeo4w/usr/src
svn co http://svn.osgeo.org/grass/grass/branches/develbranch_6/ grass6-devel

For Subsequent updates, type:

cd /osgeo4w/usr/src/grass6-devel
svn up

Download a daily snapshot from here

Follow the instructions above for grass-6.4.0, but change all grass64 to grass65, etc.

Grass-7.0.svn (trunk)

Download the grass-7.0.svn source tree with:

subversion (also see here

cd /osgeo4w/usr/src
svn checkout https://svn.osgeo.org/grass/grass/trunk grass_trunk

For Subsequent updates, type:

cd /osgeo4w/usr/src/grass_trunk
svn up

Download a daily snapshot from here and unpack to c:\osgeo4w\usr\src (if you use this method in the instructions below change "grass_trunk" to the folder name of your snapshot eg. "grass-7.0.svn_src_snapshot_2009_03_29")

Open c:\osgeo4w\etc\ini\msys.bat and at line 3 add:
```
set PYTHONPATH=%OSGEO4W_ROOT%\apps\Python25
```
Open c:\osgeo4w\usr\src\grass_trunk\lib\python\grass.py, and at line 208 change:
```
os.execvp("g.parser", [name] + argv)
```

To:

os.execvp("g.parser.exe", [name] + argv)

Open c:\osgeo4w\usr\src\grass_trunk\include\Make\Multi.make, at at line 19 change:

$(BIN)/%$(EXE): $(DEPENDENCIES)
	$(call linker)

define objs_rule
$(BIN)/$(1)$(EXE): $$(patsubst %.o,$(OBJDIR)/%.o,$$($$(subst .,_,$(1)_OBJS)))

To:

define objs_rule
$(BIN)/$(1)$(EXE): $$(patsubst %.o,$(OBJDIR)/%.o,$$($$(subst .,_,$(1)_OBJS))) $(DEPENDENCIES)
	$$(call linker)

Download the package.sh script from here

Put in c:\osgeo4w\usr\src\grass_trunk\mswindows\osgeo4w\ (you may have to create the latter two folders)

Open c:\osgeo4w\usr\src\grass_trunk\mswindows\osgeo4w\package.sh, and make the same changes as in the grass-6.4.0 section above

Also, at line 35 change:

--with-freetype-includes=/osgeo4w/include/freetype2

To:

--with-freetype-includes=/osgeo4w/include/freetype2 \
--without-cairo
