the environment variable 'XDCTOOLS_JAVA_HOME' is set, but does not appear to be a directory containing a 64-bit Java Runtime Environment (1.7 or greater);

There are several occations when I get this error.

1.) I try and open a config file. The program fails with the above error and tells me to close and relaunch the XGConf editor.

2.) I try and compile an example project. I get the error

/opt/ti/xdctools_3_32_00_06_core/xs.x86_64U: error: can't create session manager: can't find a JVM; the environment variable 'XDCTOOLS_JAVA_HOME' is set, but does not appear to be a directory containing a 64-bit Java Runtime Environment (1.7 or greater); e.g., '/usr/lib/jvm/java-7-openjdk-amd64'.
gmake: *** No rule to make target 'configPkg/linker.cmd', needed by 'configPkg/compiler.opt'.
gmake: *** No rule to make target 'configPkg/linker.cmd', needed by 'configPkg/compiler.opt'.
gmake: *** No rule to make target 'configPkg/linker.cmd', needed by 'configPkg/compiler.opt'.

If I go to the terminal and run $echo XDCTOOLS_JAVA_HOME it says

echo $XDCTOOLS_JAVA_HOME
/usr/lib/jvm/java-1.7.0-openjdk-amd64

if I run

ls /usr/lib/jvm/

I see

default-java java-1.7.0-openjdk-amd64 java-7-openjdk-amd64 java-8-oracle

I have tried manually setting the environment to each one of these in my bashrc and then sourcing the file yet still no luck.

I have see the thread at:

https://e2e.ti.com/support/embedded/tirtos/f/355/t/522505

but there doesn't seem to be any resolution.

Does anyone have any idea how I can make this editor work?

Hi Nicolas,

As mentioned in the link that you posted, XDCtools 3.32.00.06 requires 64 bit java while CCS 6.1.3 ships with 32 bit java version. This is the cause of the error you are seeing.

There are two workarounds to fix this error:

1. Create a symbolic link in XDCtools directory to 64 bit JRE.
2. Fallback to default XDCtools 3.31.3.43 shipped with CCS.

Please read through this link: e2e.ti.com/.../510357 for details.

I have tried these workarounds successfully on Ubuntu 14.04.

Hope this helps,
Vikram
