Free Compiler Setup Under Linux

From OrbiterWiki
Jump to navigation Jump to search

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 Wine 1.6.2 and ORBITER 2010-P1, using the built-in DX7 graphical client and 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 Wine, and fed back to a native multiplatform IDE - Code::Blocks. Thanks to 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. 

# 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 16.01 which is the latest working version.
svn checkout svn://svn.code.sf.net/p/codeblocks/code/tags/16.01

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. Save the following patch: 

--- compilergcc.cpp	2016-04-11 18:16:50.181091749 +0200
+++ compilergcc-new.cpp	2016-04-11 18:17:22.013365534 +0200

         CompilerFactory::RegisterCompiler(new CompilerIAR(wxT("8051")));
         CompilerFactory::RegisterCompiler(new CompilerIAR(wxT("ARM")));
     }
+    else
+    {
+    	//CompilerFactory::RegisterCompiler(new CompilerMSVC);
+        CompilerFactory::RegisterCompiler(new CompilerMSVC8);
+        //CompilerFactory::RegisterCompiler(new CompilerMSVC10);
+    }
     CompilerFactory::RegisterCompiler(new CompilerICC);
     CompilerFactory::RegisterCompiler(new CompilerGDC);
     CompilerFactory::RegisterCompiler(new CompilerGNUFortran);

Under the following full path: 

~/devel/codeblocks/16.01/src/plugins/compilergcc/compilergcc-new.cpp

And perform the actual patching: 

patch < ~/devel/codeblocks/16.01/src/plugins/compilergcc/compilergcc-new.cpp

Compiling Code::Blocks

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

Preparing MS VC2005 Express

IDE

Download the IDE and executables 

winetricks vc2005express

Select installation of only the first option (the IDE)

Platform SDK

This info comes from WineDB 

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"

Wait until the previous command finishes before executing the next one: 

WINEPREFIX=$prefixDir/$prefixName wine "C:\psdktemp\Setup.Exe"

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

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

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: 

~/devel/bin/cl.sh:

#!/bin/bash 
wine $HOME/.wine/drive_c/vc/bin/cl.exe /I"c:/vc/include" /I"c:/psdk/Include" $@ 

~/devel/bin/link.sh:

#!/bin/bash
wine $HOME/.wine/drive_c/vc/bin/link.exe /LIBPATH:"c:/vc/lib" /LIBPATH:"c:/psdk/Lib" $@

~/devel/bin/rc.sh:

#!/bin/bash
wine $HOME/.wine/drive_c/vc/bin/rc.exe /I"c:/vc/include" /I"c:/psdk/Include" $@

and make them executable: 

chmod +x ~/devel/bin/*

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 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) !
