== Building From Source
The Epple ][ Emulator is written in C+\+, and can be built
using the standard +make+ program.
The primary dependency is
http://www.libsdl.org/[Simple DirectMedia Layer] (SDL).
Your linux distribution may provide a package. Or else
you can download it directly from SDL's web site. In
either case, be sure to install the ``Development Libraries''
for your particular platform.
=== Debian Linux Example
[source,sh]
---------------------------------------------------
sudo apt-get install build-essential libsdl1.2-dev # <1>
cd
mkdir epple2
cd epple2
wget http://mosher.mine.nu/epple2/download/epple2-latest.tar.gz # <2>
2012-04-21 01:39:28 +00:00
tar xzvf epple2-latest.tar.gz
mkdir build # <3>
cd build
../epple2-1.0/configure # <4>
make # <5>
sudo make install # <6>
---------------------------------------------------
<1> Install dependencies: gcc, make, SDL
<2> Retrieve the latest Epple ][ source distribution
<3> Use this directory for a VPATH-style build
<4> Run one-time configuration script for your system. Use +--help+ for more information.
<5> Compile and link. Program will be +src/epple2+
<6> Install into standard system directories
=== Windows/MSYS Example
==== Install MinGW/MSYS
Install MSYS into +C:\msys\+
Install MinGW into +C:\msys\mingw\+
For more information on MinGW and MSYS, see http://www.mingw.org/[].
==== Install SDL
At http://www.libsdl.org/[] find the download page.
Download the ``Development Libraries'' for Win32/mingw, for example:
+SDL-devel-1.2.13-mingw32.tar.gz+ (Mingw32)
and save it to your MSYS home directory (for example, +C:\msys\home\Administrator+).
Run MSYS, and at the bash prompt, go to your home directory and
untar the SDL archive to your home directory:
[source,sh]
--------
$ cd
$ tar xzvf SDL-devel-1.2.13-mingw32.tar.gz
--------
Then follow the instructions to install SDL, for example:
[source,sh]
--------
$ cd SDL-1.2.13
$ make native
--------
==== Untar Epple ][ Source
Download the Epple ][ Source Distribution
and save it to your MSYS home directory (for example, +C:\msys\home\Administrator+).
Run MSYS, and at the bash prompt, go to your home directory and
untar the epple2 source distribution tar file. For example:
[source,sh]
--------
$ cd
$ tar xzvf epple2-1.0.tar.gz
--------
==== Build Epple ][
Then build as follows. I recommend doing a VPATH build,
where you build into a different directory than the source
directory. To accomplish this, create a new directory for
building, somewhere, such as:
[source,sh]
--------
$ cd
$ mkdir buildepple2
$ cd buildepple2
--------
Then run +configure+ from there. For the MSYS build to work,
you need some extra parameters to the build, and you could
also add some compiler options to optimize the build. For
example (from the +buildepple2+ directory you just created):
[source,sh]
--------
$ ~/epple2/configure --prefix= \
CXXFLAGS="-I/usr/include -O4 -msse3" \
CFLAGS="-I/usr/include" \
LDFLAGS="-L/usr/lib -mconsole -mthreads -mno-cygwin"
$ make
--------
If all goes well, it will build without any errors.
If you get errors about not finding +SDL.h+, make sure
SDL is installed, and make sure the configure command
is correct. (If you just run configure without the
options shown above, you will get this error at build time.)
The result of the build (on Windows platform) is
+installer/epple2.msi+
which is an installable file for Windows. To install
epple2, just double-click on this file from Explorer.
