Title: OpenJDK Path Issue?
Post by: thane on March 12, 2019, 01:27:31 AM

In TCL 10, I'm trying to code and compile Java programs using the Geany editor (geany.tcz) and OpenJDK JDK 8 (openjdk-8-jdk.tcz). In the installed JDK app various executables are in /usr/local/openjdk-8/bin/, but the app sets $PATH to /usr/local/openjdk-8/jre/bin/. Geany can't find e.g. javac (nor can it be executed in a terminal), presumably because no path to the executable exists.

Am I missing something in my setup, or is this a bug?

Does openjdk-8-jre need to be loaded as well?

I tried the JRE and JDK extensions together, and each separately. The same path was set in all cases (/usr/local/openjdk-8/jre/bin/).  Wondering if the JDK one is supposed to set /usr/local/openjdk-8/bin/ instead, or if I'm overlooking something in the setup. I don't mind looking dumb if I can get it to work!

You can manually alter the $PATH variable and see if that works?

I'll try that.

Yes, manually adding the /usr/local/openjdk-8/bin/ directory to PATH enabled javac from a terminal. Geany Java compile worked when I added the directory to PATH inside .profile and rebooted. So it looks like PATH is the issue someway. I'd still like input from people compiling Java with Open JDK (and/or JRE) to see if anyone had similar issues. It's been a while since the Open JDK extension was modified and it seems like this should have popped up pretty quickly.

Thanks for your help!

When I had this issue of Unable to locate javac and required files in JDK, I think, I had created some symlinks to a directory where my CLI editor was located or in home dire. If this helps !  .. :)

Hi thane
Something else may not be quite right. Take a look at the  .list  file:
http://tinycorelinux.net/10.x/x86/tcz/openjdk-8-jdk.tcz.list
About a third of the way down the path changes from  usr/local/openjdk-8/  to  usr/local/openjdk-8//jre/.  If the  .list  file is to be
believed, then it would appear that the  openjdk-8-jre  files were inadvertently included in the  openjdk-8-jdk  extension.
