Editing Free Compiler Setup Under Linux

This article explains how to setup a free compiler under Linux, under assumption, that Orbiter itself can be ran under Linux with Wine for testing your modules. Latest possible setup that is capable of doing it is [http://www.winehq.org Wine 1.6.2] and [http://www.orbiter-forum.com/download.php ORBITER 2010-P1], using the built-in DX7 graphical client and [http://orbiter-forum.com/showthread.php?t=18431 DX9 client]. The steps presented here have been tested on Debian-stable ("jessie"), with Nouveau graphics drivers. 
The concept is based on downloading and running MS VC executables, wrapped by [http://www.winehq.org Wine], and fed back to a native multiplatform IDE - [http://www.codeblocks.org/ Code::Blocks]. Thanks to [http://wiki.winehq.org/winetricks/ winetricks], it's of course easy to download the VC executables, along with its IDE, and run the whole IDE through Wine, but such a setup is unstable.

== Preparing Code::Blocks ==
=== Downloading build software and Code::Blocks ===
First, checkout and try to build C::B from source, to see if it the build succeeds. Alternatively, while the IDE builds, you may start hacking the source already.
<pre>
# Build reqirements
sudo aptitude install subversion wine winetricks build-essential \
libtool automake libhunspell-dev libgamin-dev libwxgtk3.0-dev

# Codeblocks
mkdir -p ~/devel/codeblocks
mkdir -p ~/devel/bin
cd ~/devel/codeblocks
# Checking out version  which is the latest working version.
svn checkout svn://svn.code.sf.net/p/codeblocks/code/tags/16.01
</pre>

=== Hacking Code::Blocks ===
The CB needs to be a bit hacked, to enable MS VC++ under Linux, which normally isn't possible. The hacking is kept to a minimum and additionally allows to use the same CB project file to compile code under Windows, using the same build targets.

Under the following full path:
<pre>
~/devel/codeblocks/16.01/src/plugins/compilergcc/compilergcc-new.cpp
</pre>
And perform the actual patching:
<pre>
patch < ~/devel/codeblocks/16.01/src/plugins/compilergcc/compilergcc-new.cpp
</pre>

=== Compiling Code::Blocks ===
<pre>
cd ~/devel/codeblocks/16.01
./bootstrap
# New compilers need the permissive flag
./configure --with-contrib-plugins=all --prefix=/usr CXXFLAGS=-fpermissive
make -j2
sudo make install
</pre>

== Preparing MS VC2005 Express ==
=== IDE ===
Download the IDE and executables
<pre>
winetricks vc2005express
</pre>
Select installation of only the first option (the IDE)

=== Platform SDK ===
This info comes from [http://appdb.winehq.org/objectManager.php?sClass=version&iId=9569 WineDB]
<pre>
prefixName=vc2005express
prefixDir=$HOME/.local/share/wineprefixes/

for ((i=1; i<=10; i++)) ; do wget http://download.microsoft.com/download/platformsdk/sdk/update/WIN98MeXP/EN-US/2600.2180/FULL/PSDK-FULL.$i.cab ; done
wget http://download.microsoft.com/download/platformsdk/sdk/update/WIN98MeXP/EN-US/2600.2180/FULL/PSDK-FULL.bat
wget http://download.microsoft.com/download/platformsdk/sdk/update/WIN98MeXP/EN-US/2600.2180/FULL/Extract.exe
WINEPREFIX=$prefixDir/$prefixName wine start.exe PSDK-FULL.bat "C:\psdktemp"
</pre>
Wait until the previous command finishes before executing the next one:
<pre>
WINEPREFIX=$prefixDir/$prefixName wine "C:\psdktemp\Setup.Exe"
</pre>
Install only the "Configuration Options" and "Microsoft Windows Core SDK". Be sure to check if the PSDK got installed under $HOME/.local/share/wineprefixes/vc2005express/Program Files. If not, (could be $HOME/.local/share/wineprefixes/vc2005express/INSTALLLOCATION), move it straight to $HOME/.local/share/wineprefixes/vc2005express/psdk

=== Symbolic links for ease ===
<pre>
cd $prefixDir/$prefixName/drive_c
mkdir vc && cd vc
ln -s ../Program\ Files/Microsoft\ Visual\ Studio\ 8/VC/bin/
ln -s ../Program\ Files/Microsoft\ Visual\ Studio\ 8/VC/include/
ln -s ../Program\ Files/Microsoft\ Visual\ Studio\ 8/VC/lib/

# Ommit this step, if the PSDK was already moved to the psdk dir
cd $prefixDir/$prefixName/drive_c
mkdir psdk && cd psdk
ln -s ../Program\ Files/Microsoft\ Platform\ SDK\ for\ Windows\ XP\ SP2/Include
ln -s ../Program\ Files/Microsoft\ Platform\ SDK\ for\ Windows\ XP\ SP2/Lib

# Link the installation links to main .wine dir
cd $HOME/.wine/drive_c
ln -s $prefixDir/$prefixName/drive_c/vc
ln -s $prefixDir/$prefixName/drive_c/psdk
</pre>

== VC++ Wine wrappers ==
For some reason the WINEPREFIX didn't work on my box, therefore I needed to use the global .wine installation. 
Create the following files:
<pre>
~/devel/bin/cl.sh:
</pre>
<pre>
#!/bin/bash 
wine $HOME/.wine/drive_c/vc/bin/cl.exe /I"c:/vc/include" /I"c:/psdk/Include" $@ 
</pre>
<pre>
~/devel/bin/link.sh:
</pre>
<pre>
#!/bin/bash
wine $HOME/.wine/drive_c/vc/bin/link.exe /LIBPATH:"c:/vc/lib" /LIBPATH:"c:/psdk/Lib" $@
</pre>
<pre>
~/devel/bin/rc.sh:
</pre>
<pre>
#!/bin/bash
wine $HOME/.wine/drive_c/vc/bin/rc.exe /I"c:/vc/include" /I"c:/psdk/Include" $@
</pre>

and make them executable:
<pre>
chmod +x ~/devel/bin/*
</pre>

== Setting up Code::Blocks ==
* Execute codeblocks
* Go to Settings->Compiler
* Select Microsoft Visual C++ 2005/2008 compiler
* Select Toolchain executables tab
* In Compiler's installation directory, paste /home/<ENTER_YOUR_USERNAME>/devel/bin and modify the Program Files, to have the .sh extensions instead of the default .exe
* In Search directories remove all search directories (the proper ones are already defined in our .sh wrappers)
* Select Build options tab and set Number of processes for parallel builds to more than 1, even if you have 1 core. This is a workaround that enables the "persistent wineserver", which greatly reduces the compilation time.
* Download, open and use [https://sf.net/p/enjomitchsorbit/codeHG Launch MFD] project file (available under launchmfd/LaunchMFD.cbp) as a template
* Download and use in your project the header file launchmfd/afxres.h. This is required for VS Express.
* Add some sources and hit The Compile Button(TM) !
