Linux + jme2(svn) + jmePhysics(svn)

teique · August 25, 2008, 12:22am

Hi,

I am new to jme, I had not much trouble compiling.

Tho I had to create some bash scripts to help it get running.

If too many things get changed they may stop working or just get useless of course :).

Btw, if you easly ran from terminal, I would like to know what commands you used (probably “ant -something…”, I guess…).

INSTRUCTIONS (commands to execute on terminal):

cd $HOME/workspace

mkdir jme2

cd jme2

cat >.jars.sh

#!/bin/bash #strPath=`pwd`"/jmonkeyengine-read-only/lib" strPath=`pwd` astr=(`find $strPath -iname "*.jar" |grep -v "macosx" |grep -v "windows"`) for(( i=0; i<${#astr[*]}; i++)); do if((i>0));then str="$str:" fi str="$str${astr[i]}" done echo "$str"

cat >.javaLibraryPath.sh

#!/bin/bash echo `pwd`"/jmonkeyengine-read-only/lib/lwjgl/native/linux:" `pwd`"/jmephysics-read-only/impl/ode/lib"

cat >jmonkeyengine-TestChooser.sh

#!/bin/bash strJars=`./.jars.sh` strJLP=`./.javaLibraryPath.sh` # download if [[ ! -d "jmonkeyengine-read-only" ]]; then svn checkout http://jmonkeyengine.googlecode.com/svn/trunk/ jmonkeyengine-read-only fi # build cd jmonkeyengine-read-only if [[ ! -f "./build/jmetest/TestChooser.class" ]]; then ant compile-test #will compile jme and test ant dist-all fi # run cd build java -Djava.library.path=$strJLP -cp "./:$strJars" jmetest/TestChooser

cat >jmephysics-TestChooser.sh

#!/bin/bash strJars=`./.jars.sh` strJLP=`./.javaLibraryPath.sh` strJME2path=`pwd`"/jmonkeyengine-read-only/build" strODEpath=`pwd`"/jmephysics-read-only/impl/ode/classes" # download if [[ ! -d "jmephysics-read-only" ]]; then svn checkout http://jmephysics.googlecode.com/svn/trunk/ jmephysics-read-only fi # build cd jmephysics-read-only if [[ ! -f "./classes/com/jmetest/physics/TestChooser.class" ]]; then cd ant ant -lib ../../jmonkeyengine-read-only/build ant release.all cd .. fi # run cd classes if [[ ! -f "properties.cfg" ]]; then cp "$strJME2Path/properties.cfg" ./ fi java -Djava.library.path=$strJLP -cp "./:$strODEpath:$strJME2path:$strJars" com.jmetest.physics.TestChooser

#each will svn download (if needed), compile (if needed), and run
./jmonkeyengine-TestChooser.sh
./jmephysics-TestChooser.sh

# to prepare them to work with eclipse just do this:
cd ..
ln -s jme2/jmephysics-read-only
ln -s jme2/jmonkeyengine-read-only

#echo "gook luck! :D"

…or just "ant" in a console in the directory where your build.xml is.

Hi,

Yep, I tried some times.

Just “ant”, only builds here.

Then I found (grep target build.xml -i |grep -v “/target”) that it would be:

ant run-testchooser

And it compiles and runs the test dialog,

but after I choose the test and click “ok” I get this:

... run-testchooser: [java] 26/08/2008 00:54:46 jmetest.TestChooser start [java] INFO: Composing Test list...

That means LWJGL ".so" linux library was not automatically found.

So I tried this command:
ant -lib lib/lwjgl/native/linux run-testchooser
and I got the same error.

1 - At build.xml I saw ant knows about linux, but it just doesnt seem to put this option "-Djava.library.path=lib/lwjgl/native/linux" when running.
2 - Also, "ant run-testchooser" is recompiling everything every time, could avoid it to speed up :).

After backup, I played a bit with build.xml in an attempt to make it know about linux native libs, but I did not succed... YET! xD

I'm not completely sure what ur asking but i do know eclipse has svn integration although I can't remember if it was a plug-in or it already had it. I was successfully able to do everything i needed to set myself up in eclipse both on my windows and kubuntu partian
