== Retrieving the Source ==
+
'''Do the following sections as normal user.'''
Use Mercurial to retrieve the latest version of the source.
+
 
  cd $HOME/ecwolf_build
+
== Create ecwolf_build directory ==
  hg clone [https://bitbucket.org/Blzut3/ecwolf https://bitbucket.org/Blzut3/ecwolf]
+
mkdir -pv ~/ecwolf_build
 +
 
 +
== Download and prepare the source ==
 +
Use Git to download the ECWolf source:
 +
  cd ~/ecwolf_build
 +
  git clone [https://bitbucket.org/ecwolf/ecwolf https://bitbucket.org/ecwolf/ecwolf.git]
 +
and create an out of tree build directory in the newly created ecwolf directory:
 +
mkdir -pv ecwolf/build
  
 
== Compiling ==
 
== Compiling ==
It is recommended that you create a build directory in the newly created ecwolf directory.
+
Inside the build directory, run CMake to generate a Makefile:
  cd ecwolf
+
  cd ~/ecwolf_build/ecwolf/build
mkdir build
+
  cmake .. -DCMAKE_BUILD_TYPE=Release -DGPL=ON
  cd build
+
Assuming there were no errors, you should be able to run make to compile:
Run CMake to generate a Makefile.  Assuming there were no errors, you should be able to run make to compile.
 
If you are recompiling, it is recommended to run '''make clean''' before the following.
 
cmake -DCMAKE_BUILD_TYPE=Release -DGPL=ON ..
 
 
  make
 
  make
An ecwolf binary should be produced.
+
A development version of ECWolf will be compiled if you do not do [[#Latest stable version]].
 +
 
 +
An ecwolf binary should be produced. To start ECWolf, the following command should work:
 
  ./ecwolf
 
  ./ecwolf
 +
If ECWolf complains you do not have any base game data set up, make sure that you have your [[Game data]] files placed in the same directory as ECWolf, in ~/.config/ecwolf or $PROGDIR. Alternatively, you can edit ~/.config/ecwolf/ecwolf.cfg to add the path for your game data to BaseDataPaths.
  
== Backup ECWolf ==
+
=== Latest stable version ===
 +
Show the latest stable version:
 +
cd ~/ecwolf_build/ecwolf &&
 +
git tag -l | tail -1
  
Follow this step if you want or manually copy (backup) ecwolf and ecwolf.pk3.
+
If you want to compile the latest stable version, run:
 +
cd ~/ecwolf_build/ecwolf &&
 +
git checkout --detach refs/tags/$(git tag -l | tail -1)
 +
and [[#Compiling|compile]].
  
Make and name a directory with the corresponding ECWolf version/revision and copy ecwolf and ecwolf.pk3 to it:

In most cases it is good idea to generate a back trace when ECWolf crashes. To make a debug build of ecwolf simply replace the cmake command with the following.
+
Maybe you have found a way to make ECWolf crash, and are interested in debugging it. First, you need to compile a debug build of ECWolf. Inside the build directory, invoke CMake to set up for compiling, but this time, the build type is set to Debug:
  cmake -DCMAKE_BUILD_TYPE=Debug
+
cd ~/ecwolf_build/ecwolf/build
 +
  cmake .. -DCMAKE_BUILD_TYPE=Debug
 +
Optionally, you may want to use some of the [[#Build options]].
 +
 
 +
After CMake is done, run "make" or to speed up compilation, run "make -j<number>", a recommended value for the "-j" option is the number of physical cores:
 
  make
 
  make
You should now be able to use gdb to generate a back trace.
+
 
 +
To run ECWolf under a debugger such as gdb, use the following command:
 
  gdb ecwolf
 
  gdb ecwolf
You probably want to log the output, so lets output to a file ecwolfdebug.log.
+
 
  set logging on ecwolfdebug.log
+
Now gdb should have you in its own command prompt:
GDB has it's own command prompt.  Use "run" to start ecwolf and use "bt" to get the back trace after a crash.
+
(gdb)
 +
 
 +
You probably want to log the output, so lets output to a file ecwolfdebug.log:
 +
  (gdb) set logging on ecwolfdebug.log
 +
 
 +
Now start ECWolf by typing in run, and pressing enter:
 
  (gdb) run
 
  (gdb) run
  (gdb) bt
+
 
To exit GDB's command prompt, use "quit", "q" or Ctrl-D.
+
Or put any command line parameters to ecwolf after run:
 +
  (gdb) run <command line parameters>
 +
To see the available command line parameters for ECWolf, type "run --help" and press enter.
 +
 
 +
If ECWolf crashes, gdb may be able to tell you the source file and line number it crashed in. Typing in the command backtrace or bt will produce information telling the last function calls, showing how execution got to the point where it crashed:
 +
(gdb) backtrace
 +
All output will be copied into the ecwolfdebug.log, which can then be scrutinized later, or perhaps posted to the [https://bitbucket.org/ecwolf/ecwolf/issues Bug Tracker] for other developers to look at.
 +
 
 +
To exit gdb's command prompt, type quit, q or press Ctrl-D:
 
  (gdb) quit
 
  (gdb) quit
 +
If you want to free up space, run "make clean" to remove the files generated by the compilation.

and create an out of tree build directory in the newly created ecwolf directory:

mkdir -pv ecwolf/build

Compiling

Inside the build directory, run CMake to generate a Makefile:

cd ~/ecwolf_build/ecwolf/build
cmake .. -DCMAKE_BUILD_TYPE=Release -DGPL=ON

Assuming there were no errors, you should be able to run make to compile:

make

A development version of ECWolf will be compiled if you do not do #Latest stable version.

An ecwolf binary should be produced. To start ECWolf, the following command should work:

./ecwolf

If ECWolf complains you do not have any base game data set up, make sure that you have your Game data files placed in the same directory as ECWolf, in ~/.config/ecwolf or $PROGDIR. Alternatively, you can edit ~/.config/ecwolf/ecwolf.cfg to add the path for your game data to BaseDataPaths.

Latest stable version

Show the latest stable version:

cd ~/ecwolf_build/ecwolf &&
git tag -l | tail -1

If you want to compile the latest stable version, run:

cd ~/ecwolf_build/ecwolf &&
git checkout --detach refs/tags/$(git tag -l | tail -1)

and compile.

After compiling, backing up and optionally installing the latest stable version, run:

cd ~/ecwolf_build/ecwolf &&
git checkout master

Backup

If you want to backup ECWolf, do the following:

Create and name a directory with the corresponding ECWolf version/revision, build type and copy ecwolf and ecwolf.pk3 to it:

cd ~/ecwolf_build/ecwolf/build &&
if [ -f CMakeCache.txt ]; then
k="$(sed -n 's/.*CMAKE_BUILD_TYPE:STRING=\(.*\)/\1/p' CMakeCache.txt)"; else k=''; fi &&
if [ -n "$k" ]; then b="-BuildType$k"; else b=''; fi &&
BACKUPECWOLF="../../$(sed -n 's/.*#define GIT_DESCRIPTION "\(.*\)".*/\1/p' src/gitinfo.h)$b" &&
mkdir -pv "$BACKUPECWOLF" &&
cp -v ecwolf ecwolf.pk3 "$BACKUPECWOLF"/

Files are located at:

/home/<your username>/ecwolf_build/<your newly created directory>

Updating

When you wish to update ECWolf, copy and paste the following:

cd ~/ecwolf_build/ecwolf &&
git pull

When the update finish, go to #Compiling.

Installation

  • ecwolf = Stable version
  • ecwolf-alpha = Development version

Commands beginning with "sudo" will require temporary superuser privileges.

If you want to install ECWolf, do the following:

Create /usr/games/ecwolf and /usr/games/ecwolf-alpha directories:

sudo mkdir -pv /usr/games/ecwolf /usr/games/ecwolf-alpha

Copy ecwolf and ecwolf.pk3 to /usr/games/ecwolf/ or /usr/games/ecwolf-alpha/:

cd ~/ecwolf_build/ecwolf/build &&
h="$(sed -n 's/.*#define GIT_HASH "\(.*\)".*/\1/p' src/gitinfo.h)" &&
if [ -z "$(git describe --exact-match --tags $h 2>/dev/null)" ]; then
d=-alpha; else d=''; fi &&
sudo cp -v ecwolf ecwolf.pk3 /usr/games/ecwolf$d/

Create launch script:

cd ~/ecwolf_build/ecwolf/build &&
h="$(sed -n 's/.*#define GIT_HASH "\(.*\)".*/\1/p' src/gitinfo.h)" &&
if [ -z "$(git describe --exact-match --tags $h 2>/dev/null)" ]; then
d=-alpha; else d=''; fi &&
printf %s "\
#! /bin/sh
exec /usr/games/ecwolf$d/ecwolf \"\$@\"
" > ecwolf$d.sh &&
chmod 755 ecwolf$d.sh &&
sudo mv -v ecwolf$d.sh /usr/bin/ecwolf$d

Now from a terminal you should be able to run ecwolf or ecwolf-alpha from any user account.

Uninstallation

Remove /usr/games/ecwolf directory and all its files:

sudo rm -rfv /usr/games/ecwolf

Remove ecwolf script:

sudo rm -fv /usr/bin/ecwolf

Remove /usr/games/ecwolf-alpha directory and all its files:

sudo rm -rfv /usr/games/ecwolf-alpha

Remove ecwolf-alpha script:

sudo rm -fv /usr/bin/ecwolf-alpha

Developing

This page has helped you compile ECWolf, but perhaps you are interested in debugging the code or submitting code changes or fixes for inclusion. This section is intended for more advanced users who may be unfamiliar to CMake or debugging on Linux systems.

Debugging

Prerequisite:

Maybe you have found a way to make ECWolf crash, and are interested in debugging it. First, you need to compile a debug build of ECWolf. Inside the build directory, invoke CMake to set up for compiling, but this time, the build type is set to Debug:

cd ~/ecwolf_build/ecwolf/build
cmake .. -DCMAKE_BUILD_TYPE=Debug

Optionally, you may want to use some of the #Build options.

After CMake is done, run "make" or to speed up compilation, run "make -j<number>", a recommended value for the "-j" option is the number of physical cores:

make

To run ECWolf under a debugger such as gdb, use the following command:

gdb ecwolf

Now gdb should have you in its own command prompt:

(gdb)

You probably want to log the output, so lets output to a file ecwolfdebug.log:

(gdb) set logging on ecwolfdebug.log

Now start ECWolf by typing in run, and pressing enter:

(gdb) run

Or put any command line parameters to ecwolf after run:

(gdb) run <command line parameters>

To see the available command line parameters for ECWolf, type "run --help" and press enter.

If ECWolf crashes, gdb may be able to tell you the source file and line number it crashed in. Typing in the command backtrace or bt will produce information telling the last function calls, showing how execution got to the point where it crashed:

(gdb) backtrace

All output will be copied into the ecwolfdebug.log, which can then be scrutinized later, or perhaps posted to the Bug Tracker for other developers to look at.

To exit gdb's command prompt, type quit, q or press Ctrl-D:

(gdb) quit

If you want to free up space, run "make clean" to remove the files generated by the compilation.

Build options
