-THIS GUIDE ONLY DESCRIBES BUILDING BASILISK OR SHEEPSHAVER FROM THE OFFICIAL SOURCE CODE.\\ +**HOWEVER NOTE:** This guide describes building BasiliskII and Sheepshaver from the currently most advanced code from kanjitalk755 fork:  
-There are other repositories with forked code, solving particular problems. You are on your own if you want to build the code in those repositories!\\ +  * https://github.com/kanjitalk755/macemu

-===== ++++  WORK IN PROGRESS, HELP IF YOU CAN ++++ ===== 
  
-==== Preparing your build environment ==== 
  
-Common assumptions:\\ +==== Building BasiliskII and SheepShaver in Windows ====
-  * You have a folder called "src" inside your home folder in which you are going to place all downloads mentioned below. The folder structure we are assuming looks like this: +
-  * src +
-  * src\SDL-1.2.15 +
-  * src\macemu\BasiliskII  (this folder will be created automatically if you follow the directions below) +
-  * src\macemu\SheepShaver (this folder will be created automatically if you follow the directions below)+
  
-=== Windows ===+=== Prepare your build environment === 
 +Install **msys2 32-bit** from https://www.msys2.org/wiki/MSYS2-installation/ in c:\msys32 and start msys2.exe
  
-You need a Windows port of the GCC and G++ compilers, X-headers, libgnome development etc. You can use either Cygwin 1.5 or 1.7, or MinGW with MSYS:+**Note:** You might have to follow the instructions here: https://www.msys2.org/news/#2020-06-29-new-packagers \\ 
 +to get the installation going.\\
  
-  * To set up Cygwin, follow [[https://www.cygwin.com/|these instructions]]. +Update msys2: 
-  * To set up MinGW with MSYS, follow [[http://www.mingw.org/wiki/Getting_Started|these instructions]].+  * pacman -Syu  (closing and restarting msys2 when requested) 
 +  * pacman -Su 
  
-When building on Windows, the term "home folder" means your Cygwin or MSYS home folder, e.g. home/yourusername or msys/1.0/home/yourusername .\\+Install the following packages: \\ 
 +  * pacman -S base-devel 
 +  * pacman -S git 
 +  * pacman -S mingw-w64-i686-toolchain 
 +  * pacman -S mingw-w64-i686-glib2 
 +  * pacman -S mingw32/mingw-w64-i686-gcc 
 +  * pacman -S mingw32/mingw-w64-i686-gtk2 
 +  * pacman -S mingw32/mingw-w64-i686-SDL2
  
 +Close msys2 \\
 +Start mingw32.exe \\
  
-==Build SDL 1.2.15==+Download the source code (we use the source from kanjitalk755 on github):
  
-  * Download the source code from: http://www.libsdl.org/release/SDL-1.2.15.zip +  git clone https://github.com/kanjitalk755/macemu
-  * Extract the zip file to the SDL-1.2.15 folder in your "src" folder. +
-  * start Cygwin or MSYS shell.  +
-  * (only in case you're using Cygwin 1.7 execute: "chmod 755 /usr/bin/set-gcc-default-3.sh" and "/usr/bin/set-gcc-default-3.sh" effectively setting Cygwin 1.7 to use the gcc version 3 compiler in stead of the standard gcc version 4 compiler). You can reverse this by executing: "chmod 755 /usr/bin/set-gcc-default-4.sh" and "/usr/bin/set-gcc-default-4.sh" +
-  * cd to the folder containing the SDL source and run the following commands: \\+
  
-  ./autogen.sh +== Build Basilisk II ==   
-  ./configure --disable-shared +  cd macemu/BasiliskII/src/Windows 
-  make +  NO_CONFIGURE=1 ../Unix/autogen.sh 
-  make install +  ./configure --with-bincue 
-   +  make  
-If you want to install multiple versions of SDL, use these commands:\\ +  strip BasiliskII.exe 
-  ./autogen.sh +  strip BasiliskIIGUI.exe
-  ./configure --disable-shared --prefix=`pwd` +
-  make +
-  make install +
-  PATH=`pwd`/bin:$PATH +
-  export PATH+
  
-* You will then need to cd into the corresponding SDL folder every time you start Cygwin or MSYS and set and export the path to sdl-config to build SheepShaver, so SDL libs and sdl-config file can be found. \\ +== Build SheepShaver == 
- +  cd macemu/SheepShaver  
-== To build the Windows GUIs == +  make links
-The Windows GUIs are built by using the gtk+ Win32 development packages. This section assume you installed them in C:\GTK +
-  * Install http://sourceforge.net/projects/gladewin32/files/gtk%2B-win32-devel/2.12.9/gtk-dev-2.12.9-win32-2.exe/download +
-  * Find a file called pixman-1.pc on the Internet and place it in: C:\GTK\lib\pkgconfig\ +
-  * Start the Cygwin or MSYS shell +
-  * Export the path to PKG_CONFIG \\ +
-   +
-  (disregard a possible error message) +
-  export PKG_CONFIG_PATH='C:\GTK\lib\pkgconfig\' +
- +
-== OSX Snow Leopard== +
-Please note that the current code only builds in Snow Leopard with XCode 3.x (latest 3.2.6)! Newer versions of OSX and XCode are not supported. +
- +
-To build BasiliskII there is only the command line method. To build SheepShaver with OSX you have two options. You can use the command line method, or the XCode project method. Both are described below. In any case you need Xcode installed. The Xcode method requires that the 10.4 SDK be installed. If you did not install it when you installed Xcode, run the Xcode installer again. In the Installation Type dialog, select the option to install the 10.4 SDK (it is unchecked by default).\\ +
- +
-**Using the command line** \\ +
-Cd to your "src" folder.\\ +
-  * Download the source code from: http://www.libsdl.org/release/SDL-1.2.15.zip +
-  * unpack the code in the folder "src/SDL-1.2.15" folder +
-  * start a terminal window +
-  * cd to the folder containing the SDL source and run the following: +
- +
-  ./autogen.sh +
-  ./configure --disable-shared --prefix=`pwd` +
-  make +
-  make install +
-  PATH=`pwd`/bin:$PATH +
-  export PATH +
- +
-* You need to cd into the SDL folder every time you start a new terminal window and export the path (the last two command lines above) to sdl-config to build SheepShaver, so SDL libs and sdl-config file can be found. \\ +
- +
-**Using Xcode (3.x, with 10.4 SDK installed)** \\ +
-  * download the SDL-framework from [[http://www.libsdl.org/release/SDL-1.2.15-OSX10.4.dmg]]  +
-  * find the SDL.framework folder and copy it to your /Library/Frameworks/ folder. +
- +
-== Linux == +
-You need GCC and G++ installed, plus several other development packages, like SDL-1.2.15 development, the X-headers, the libgnome-development package, cvs access \\ +
- +
-  * Your SDL installation and other packages should be found automatically when you start building SheepShaver or BasiliskII +
- +
-=== Actions for all environments === +
- +
-Download the source code:  +
- +
-== If you have Git installed == +
- +
-Use the following command to download the source code:\\ +
- +
-  git clone https://github.com/cebix/macemu. +
- +
-Find the "macemu" folder in your git repository folder and copy it into your "src" folder. This will create the folders BasiliskII and SheepShaver in the "src/macemu" folder.\\  +
- +
-== If you don't have Git installed == +
- +
-  * Go to https://github.com/cebix/macemu and download the source code with "Download ZIP"  +
-  * Extract the zip file in your "src" folder. This will create the folders BasiliskII and SheepShaver in the "src/macemu" folder.\\ +
- +
-The SheepShaver code is not needed if you only want to compile BasiliskII.\\     +
- +
-==== Building BasiliskII in Windows ==== +
-If your version of gcc is 4.7.0 or more recent, you need to remove all occurrences of \\ +
-   +
-  -mno-cygwin +
- +
-from the build files, as this option has been deprecated and will give an error while building. See [[http://stackoverflow.com/questions/6034390/compiling-with-cython-and-mingw-produces-gcc-error-unrecognized-command-line-o/6035864#6035864|this discussion]] for more details.\\ +
- +
-Now cd to the BasiliskII folder and:\\+
   cd src/Windows   cd src/Windows
   NO_CONFIGURE=1 ../Unix/autogen.sh   NO_CONFIGURE=1 ../Unix/autogen.sh
-  ./configure +  ./configure --with-bincue
-   +
-==Optional: prepare for building the GUI== +
-Edit the file "make" in the Basilisk/src/Windows folder.  +
-   +
-Change  +
-  "WANT_GTK = no"  +
-to  +
-  "WANT_GTK = yes" +
- +
-Open a command window in Windows and enter: +
-  pkg-config --cflags gtk+-win32-2.0 +
-  pkg-config --libs gtk+-win32-2.0 +
-and copy-paste the outputs of the respective commands behind the lines GTK_CFLAGS = and GTK_LIBS = +
-   +
-It would look something like:   +
-  WANT_GTK = yes +
-  GTK_CFLAGS = -mms-bitfields -IC:/GTK/include/gtk-2.0 -IC:/GTK/lib/gtk-2.0/include -IC:/GTK/include/atk-1.0 -IC:/GTK/include/cairo -IC:/GTK/include/pango-1.0 -IC:/GTK/include/glib-2.0 -IC:/GTK/lib/glib-2.0/include -IC:/GTK/include/freetype2 -IC:/GTK/include\\ +

- +
-=== Finally run: ===+
   make   make
-  strip BasiliskII.exe+  strip SheepShaver.exe 
 +  strip SheepShaverGUI.exe

-You have two option to build Sheepshaver in OSX, using the command line or using the XCode project file. Stick to the method you used to prepare your build environment as described above. \\+
  
-**Using the command line** \\+We recommend compiling from the kanjitalk755/macemu repository:
  
-If you started a new terminal window, then don't forget to export the path to SDL (see above at "Preparing your build environment"):\\+== BasiliskII ==
  
-  cd src/SDL-1.2.15/ +  git clone https://github.com/kanjitalk755/macemu

   make   make
-  make SheepShaver_app+  strip BasiliskII 
  
-**Using the Xcode project file**\\ +== SheepShaver ==
-Open a terminal and cd to the SheepShaver folder and do: +
-  make links  +
-Close the terminal \\ +
-  * open the src/SheepShaver/src/MacOSX/SheepShaver.xcodeproj file. Xcode opens. +
-  * in the "Debug | SheepShaver | …" drop-down menu choose "Release" +
-  * build the project by selecting Build in the Build menu +
-  * SheepShaver is then found in the src/SheepShaver/src/MacOSX/build/release/ folder +
-==== Building SheepShaver in Linux flavours====+
  
-  * SheepShaver currently suffers from issues regarding running in a window/full screen. For full screen support, follow the directions below. However, if you want a stable build for windowed use, delete "--enable-sdl-video" and "--enable-sdl-audio" from the ./configure step. +  git clone https://github.com/kanjitalk755/macemu 
- +  cd macemu/SheepShaver
-Ubuntu, Fedora, SuSE:\\ +
- +
-cd to the SheepShaver folder and: \\+
   make links   make links
   cd src/Unix   cd src/Unix
   NO_CONFIGURE=1 ./autogen.sh   NO_CONFIGURE=1 ./autogen.sh

   make   make
   strip SheepShaver   strip SheepShaver
  
 +== Sheep_net driver ==
 +If you plan to use the sheep_net driver for networking, you should compile your own:
  
-==== Cross-compiling in Linux for Windows ==== +  cd macemu/BasiliskII/src/Unix/Linux/NetDriver
- +
-These instructions apply to Ubuntu 12.10 32Bits, Debian 7.1 64bits  +
- +
-Start with preparing your build environment: +
-Make sure you have installed build-essentials, automake, autoconf and mingw32 +
- +
-You can install these prerequisites from the command line with: +
-  sudo apt-get install build-essential automake autoconf mingw32 +
-   +
-The rest of these instructions assume you use \home\yourusername\src as folder for the source code for SDL and BasiliskII: +
- +
-Download the SDL source code from the command line and build SDL: +
-  wget http://www.libsdl.org/release/SDL-1.2.15.tar.gz +
-  tar -xzf SDL-1.2.15.tar.gz +
-  cd SDL-1.2.15 +
-  ./configure --host=i586-mingw32msvc --disable-shared --prefix=`pwd`+
   make   make
-  make install +  sudo make dev 
-  export PATH=`pwd`/bin:$PATH +  sudo chown [user account] /dev/sheep_net 
- +  sudo make install 
-For BasiliskII, go to the /src/BasiliskII/src/Windows folder and enter: +  sudo modprobe sheep_net
-  NO_CONFIGURE=1 ../Unix/autogen.sh +
-  echo ac_cv_have_win32_exceptions=yes > extra.cache +
-  ./configure --host=i586-mingw32msvc --cache-file=extra.cache --enable-sdl-video --enable-sdl-audio --enable-jit-compiler +
-  make +
- +
-For SheepShaver, go to the SheepShaver folder and enter: +
-  make links +
-  cd /src/Windows +
-  NO_CONFIGURE=1 ../Unix/autogen.sh +
-  echo ac_cv_have_win32_exceptions=yes > extra.cache +
-  ./configure --host=i586-mingw32msvc --cache-file=extra.cache --enable-sdl-video --enable-sdl-audio +
-  make +
- +
-If you also want to build the Basilisk GUI: +
-  wget http://ftp.gnome.org/pub/gnome/binaries/win32/gtk+/2.24/gtk+-bundle_2.24.10-20120208_win32.zip +
-Extract the archive in your /src folder. Next, create a file /src/basilisk/bin/pkg-config containing: +
-  #!/bin/sh +
-  PKG_CONFIG_LIBDIR=/opt/basilisk/lib/pkgconfig \ +
-  PKG_CONFIG_PATH=/opt/basilisk/lib/pkgconfig /usr/bin/pkg-config $* +
- +
-and chmod +x it to make it executable +
- +
-Next, patch up the libraries: +
-  cd /src/basilisk +
-  sed -i 's|^prefix=.*$|prefix=/src/basilisk|g' lib/pkgconfig/*.pc +
-  cd ./lib +
-  for f in *.lib; do mv $f lib${f%%lib}a; done +
- +
-Use this configure command for Basilisk II: +
-  ./configure --host=i586-mingw32msvc --cache-file=extra.cache --with-gtk --disable-gtktest --enable-sdl-video --enable-sdl-audio --enable-jit-compiler +
- +
-You have to edit the makefile in the BasiliskII/src/Windows folder:  +
-change a reference to b2ether/Packet32.cpp to b2ether/packet32.cpp before finally entering: +
-  make +
- +
-==== Tidbits ==== +
- +
-  * Source code for Visual C for basiliskII and SheepShaver: +
-There are some unfinished attempts (jan. 2011) to update the source code for Basilisk and SheepShaver for Windows that build in Visual C. The code also builds in MinGW. It originates from here: https://github.com/tycho/basiliskii and https://github.com/tycho/sheepshaver \\ +
