Hi,

My ant was obviously broken, I've downloaded fresh version and then managed
to build X10 from sources with MPI support. Now the MPI RT implementation
works fine.


- get and install latest Oracle Sun Java from
http://www.oracle.com/technetwork/java/javase/downloads/java-se-jdk-7-downlo
ad-432154.html:
# wget http://download.oracle.com/otn-pub/java/jdk/7/jdk-7-linux-x64.rpm
# rpm -ivh jdk-7-linux-x64.rpm
# export JAVA_HOME=/usr/java/jdk1.7.0
# /usr/java/jdk1.7.0/bin/java -version
java version "1.7.0"

- download apache ant binary edition from
http://ant.apache.org/bindownload.cgi
- unpack it to "/home/install/ant/apache-ant-1.8.2"
- set ANT_HOME:
# export ANT_HOME="/home/install/ant/apache-ant-1.8.2"

- get X10 sources from trunk:
# cd /home/apps/x10
# svn co https://x10.svn.sourceforge.net/svnroot/x10/trunk x10-trunk

- build sources:
# cd x10-trunk/x10.dist
# ant -DX10RT_MPI=true dist
...
BUILD SUCCESSFUL
Total time: 4 minutes 23 seconds


Kind regards, Marko Kobal

I believe this is an ant configuration issue.  Perhaps ANT_HOME is not set
correctly, or needs to be unset, or perhaps JAVA_HOME needs to be set.
There is an error similar to this at the bottom of
http://wiki.apache.org/ant/AntNewbies

Also, I'm not positive, but I believe you need to specify the options before
the build target, with "ant -DX10RT_MPI=true dist", instead of "ant dist
-DX10RT_MPI=true".

Hi,



On my CentOS 5.6 64bit system I have:



# java -version

java version "1.7.0"

Java(TM) SE Runtime Environment (build 1.7.0-b147)

Java HotSpot(TM) 64-Bit Server VM (build 21.0-b17, mixed mode)



ant.x86_64                                  1.6.5-2jpp.2
installed

ant-nodeps.x86_64                           1.6.5-2jpp.2
installed



When I try to build I get the following error:



# cd x10.dist && ant dist -DX10RT_MPI=true

Error: Could not find or load main class
org.apache.tools.ant.launch.Launcher



What else am I missing?





Kind regards, Marko Kobal
