This page explains how to compile Globulation 2 on windows using mingw.
Installing required software for tutorial
Setting up Python, Scons, Mercurial, and NSIS
- Download and install Python into the directory "C:\Python26" (default install is Python_version_number, change this number to 26 during installation if you want to avoid a BUG, even if you got Python30 )! the Version 3 may be not retro-compatible !
- Download and install scons-1.1.0 into the same directory as the python install (C:\Python26\) If you are installing a more recent scons version than the scons-1.1.0 An issue will occurred. An easy measure is not yet defined. The Version 2 has not been test yet (We are testing this And will update this soon) !
- Download and install mercurial Mercurial-1.6.0 stable without TortoiseHg.The newiest HG mercurial with Tortoise has not been test yet !
- The old Mercurial (outdated) References for this Wiki was (outdated) Mercurial locally so the command hg will work. When you get to the end of the install, make sure you check "add mercurial to your computers search path" or something similar. PLEASE INSTALL ONLY ONE Mercurial ! The 1.6.0 version works Well !
OPTIONAL DOWNLOAD:
(To create a windows installer)
- Download and install NSIS into all its default installation folder "C:\Program Files\NSIS\".
(To be proud of using MS WINDOWS GUI)
- find 7zip or winrar for a more friendly GUI than command line, We are under Windows, do we ? links will be added later.
(In case of Bug or Issues, who knows ? )
- find notepadd++ (free gnu software) to edit code in case of BUG, links will be added later.
Setting up MinGW and MSYS
- Download and install MinGW-5.1.4.exe into the directory c:\mingw (lower case).
- During installation, select "Current" when asked what version, and then
- select the "MinGW base tools" (by default) and g++ compiler packages only
- Download and install MSYS-1.0.10.exe into the directory c:\msys\1.0\ (lower case).
- At the end of the installation, it will ask you if you want to continue with the post-install. Select yes, and yes again when it ask if you have mingw installed.
- Then -the black windows prompt- will continue asking you to indicate where the directory is installed,type :
- c:/mingw (yes, with a forward slash -linux habit to have- as the program prefers it that way).
- Open msys by double clicking the desktop icon, type the following code into the emulated *NIX-shell, then be sure to close the window/program so it will takes effect:
echo "c:/mingw /mingw" > /etc/fstab
Compiling Prerequisites
- Open in a news Windows Explorer windows the path "C:\msys\1.0" (we will drop some files into it later from an archive)
- Download glob2_required_libs_mingw-scons.tar.bz2 and put it in the home directory of msys (c:\msys\1.0\home\XXX\ where XXX is the username)
- Open it with a bz2-tar archiver application like Winrar,or 7z, and
- Drag and drop All Directories from the Archivers (e.g Winrar) into the path "C:\msys\1.0" (remember we already got a windows ready for that) , tell yes if it ask for over writting, or already existing files/folders. This could take a While.
NOTE: On Windows VISTA and Above you might need the Administrators Right to access copy or drag and drop files into the C Drive trees. an inheritance from linux chmod :(
ONCE Done, close the Archiver, and Windows that we opened for the drag and drop.
OLD_METHODE , 'command line geek' :
- Double click the MSYS icon that has been placed on your desktop during MSYS's installation.
- Go in the directory where you put the glob2_required_libs_mingw-scons.tar.bz2 (for example cd ~) and untar the libraries using the command below. This process could take a while:
tar jxf glob2_required_libs_mingw-scons.tar.bz2 -C /
Compiling Globulation 2
Step 1: Preparing for a compile
Compiling from Released source code
- Download and extract the release to c:\msys\1.0\home\XXX\ (where XXX is the username), then run (changing the version numbers):
mv glob2-x.x.xx glob2_source
Compiling from Mercurial source files
- Download Globulation 2 from mercurial
hg clone http://hg.globulation2.org/glob2-new glob2
- The above command gets you all the history of glob2 back to November 2001 when it all began.
- Pick a version you want to compile
cd glob2
hg branches
hg tags
- these commands give you an overview of what branches and tags exist.
- Tags are used to mark certain versions like when glob2 publishes a new released. beta4.5 for example is the 5th version of the beta-4 series of releases. This is better and more stable than the beta4.4 but should not desync against beta4.1. If you only want to play glob2 beta4, use the latest tag beta4.whatever. tip is a special tag. It is the revision last committed to the repository. In general this is not what you want but you get it by default.
- Branches are used to mark a sequence of revisions that are not necessarily all stable. Somewhere after beta4.5 on the beta4-rc branch there may be versions that don't compile. If you want to help on a beta4.6 you would need to get the branch beta4-rc. default is the main branch. If you want to play this is not the branch you want. If you want to fix bugs, this is not what you want as bugs get fixed in the earliest supported branches (those with an -rc). If you want to implement new features that you are sure to finish do it in default. If your feature is complex, use default but branch off a feature branch (hg branch my-complex-feature).
- update to the right revision.
hg update -C \[branch name or tag name you picked above\]
Step 2: actually compiling
- Start compiling Globulation 2.This Stage could lead to some ISSUES,they are disccuss in the proper section below. Don't worry about the warnings while compiling. If something is wrong, it will grind to a halt and it will let you know why. To compile, run (inside the folder glob2):
scons
- Once compiling has finished
- Make a 'TEST' directory call "test" or "whatever" using MS WINDOWS in your desktop or 'elsewhere' for the simplest example we will set it up in our windows desktop :) .
- Copy into it all the file found in "C:\msys\1.0\local\lib" then do not forget to do,
- Copy and past of the Glob2.exe from "C:\msys\1.0\home\XXX\glob2_source\src\" where XXX is the PC's name or user into this 'Test' directory you have made in your desktop, and...
- launch it ! ENJOY IT !
If any DLL is missing find it in your local computer and copy it into the 'test' folder on your desktop.
Another old_school Method for testing ( Did not work on Windows, at least mine :( !
-Once compiling has finished, run (if you 'r ,kamikaze, the following to prepare Globulation 2 for testing:
cp -a /local/bin/SDL.dll /local/lib/*.dll .
cp -a ./src/glob2.exe .
-Run glob2.exe from the glob2_source directory and play :) [this stage too might lead to lack of dll,bond ! who said that command line are better ....
Building a Globulation 2 NSIS installer
- In MSYS, run the following codes to compile a windows installable exe file:
cd glob2_source
cd windows
glob2_make_win32.sh
- If all things go well, an exe ready for installation on windows computers is now ready within the windows folder. Test it (install and play), and if it works, send it to your friends ;)
Possible Issues
ISSUE #1.
Make sure you have no hidden GNU-GCC installed somewhere. GCC is for example included in the FreePascal-Compiler. (You won't find any Lib anymore if another GCC is activ.)
ISSUE #2.
Make sure path to GCC is set in Path Enviroment Variable. The Scons-Script just aborts (can't find libSDL) if it is not.
ISSUE #3. scons: No such file or directory Trouble
I got this trouble as many other people (http://globulation2.org/forums/viewtopic.php?t=210).
It is not quite easy to explain how to make-it-works,The solution could be fixed easily but have to be dynamic with ever new python & scons product version .
So this Trouble could come over again later.
- Where that Trouble come from ?
This comes from a "linux-kind-link" who has been designed for Python 2.6 AND scons-1.1.0 Versions, Guess what this link is (OUT TO DATE) due to the fact that the Python today version and scons have evolve their name, their path could too !
That said, as you see The Trouble will come over and over if the way to bond the scoms path to the mingw sh (linux command bash, & emulated environment) will stay like that.
- What the Community could do ?
Here some ideas:
We might need to keep up-to-date either this Wiki page and the scoms file provided in the tarball file call 'Prerequisites' (http://dl.sv.nongnu.org/releases/glob2/mingw/glob2_required_libs_mingw-scons.tar.bz2). Yes, telling people what Python & scoms version STRICTLY to use and keeping this up to date with news release (because their release will getting old and might not stay available for download).
- What YOU can do to make it works ?
The FIRST LAZY WAY:
Remove the actual Python and scons program from your computer, then download and install the old python2.6 **AND** scons1.1.0 version for windows if they are still available for download.
The SECOND LAZY WAY: (has not been test yet and may not solve the trouble)
Download the latest python and install it on c:\python26 and the latest scons on c:\python26\lib\site-packages\scons-1.1.0\
OR THE MOST COMPLICATED WAY: Editing the scoms file.
File with no Extension and normaly "located" at "c:\msys\1.0\bin\" or might also work or be found there at "c:\mingw\bin\" you should use a proper Text Editor , do not even think to use the MS notepad because it does sometime files coruption, at least you may use MS WORDPAD at your own files risk !,Better to use the Free Notepad++ who really edit well available as portable application also.
For Editing the ORIGINAL scoms file :
Replace the line:
#! C:/Python26/python ,
by your real information and software version and path location:
#! Drive:/Python_version_location/python
AND the two next occurrences of the expression or chart: 'scons-1.1.0'
by your actual 'scons-version.x.x.x.'
Try to launch again 'scoms' in the 'glob2_source' folder from MSYS application (the emulated *NIX environment & prompt) , in fact the STEP 2 of this Wiki page, If 'scoms' start compiling - a lot of information will be writting in the MSYS application windows, you 'r done !
you might need to check and found if your scons is on the right path as for the scons v1 it is like
C:\Python27\Lib\site-packages\scons-1.3.0\SCons\Script\SConscript.pyc
IF the path Drive:\Python_version_path\Lib\site-packages\scons-version.x.x.x\SCons\" is not , you may need also to modified some other chart or expression in quotation mark e.g 'scons-1.1.0' to 'scons-2.0.0'
You should found anyway on your computer somewhere the file 'SConscript.pyc' if the scons is correctly installed.
This Help is there and is provided AS IS , its works on my Windows Vista 32bit, and this Details Help should stay here long enought the file glob2_required_libs_mingw-scons.tar.bz2 containing the **OUTDATED** 'scoms link code' ! ALSO I M SORRY FOR THE OVERALL TEXT DESIGN but I m not use with this Web-tools and formatting ! even making a web-link is a problem well the help page is not working so feel free to correct my text design code.
ISSUE #4.
Some other little trouble occurred with .dll location after a correct compilation using the old method ,but this could be handle quickly using the method with the use of Windows GUI, remember the 'test' folder on your desktop :) .
Conclusion
That concludes this Mingw compilation tutorial.Well it does have again some correction to bring to this tutorial,like the use of Windows GUI for un-tarballing archives and copy and past more than the use of command line, after all we are under windows and this is a windows topic so we will try to clear code line who can be done by GUI application such as 7zip or Winrar, and many else page-improvement.
Also to give you and idea on a 4 cores pentium cpu @ 2.33GHZ the compilation of the RC beta5 got 12 minutes and the binary (Glob2.exe file) "pound" 133MB !! well the other geek guys made one at 98MB so we are 1.32 time more weighty with this type of compilation. But clearly as today the comparison between Beta4 & Beta 5 is amazing by the Glob2 binary file size ! from 4.8kb to 100Mb .
If you have any problems, please write a bug report and one of the Windows maintainers should be able to help you. More information on bug reports can be found at the Bug Reports page.
Also think about the IRC , easy connexion via YOG.
Happy compiling.
