Ubuntu Installation (Java Error)

[zealbell]

Hi, Please I am having volatile issues configuring TornadoVM on Ubuntu 22.10. I cloned the 'beehive-lab/TornadoVM' repository using Intellij and then installed asper

$ ./scripts/tornadoVMInstaller.sh --graal-jdk-17 --opencl --ptx (since: AMD RYZEN 9 5950X + RTX 3080)

I then opened the module TornadoVM/tornado-examples as a new project but then the build fails with the message

java: error: release version 5 not supported

Module tornado-examples SDK 17 does not support source version 1.5. 
Possible solutions:
- Downgrade Project SDK in settings to 1.5 or compatible. Open project settings.
- Upgrade language version in Maven build file to 17. Update pom.xml and reload the project.

(Tried possible solutions above, I got NOTHING, so I reverted changes made). Currently my project's (.../TornadoVM/tornado-examples) sdk is @ .../TornadoVM/etc/dependencies/TornadoVM-GraalJDK17

Also at the pom.xml the truffle dependency just goes red in between the tags ( <groupId>, <artifactId> and <version>) then I noticed jdk-8 in between the <id> tags. I am just a bit confused and suspicious about what 8 has to do with installing graaljdk-17 earlier, could this be the reason my build isn't successful? could it just be 8? (I am still yet to understand how 5 came about earlier)

                    <version>${graal.version}</version>

JDK 8 is not supported. The two JDK versions supported are 11 and 17, and we highly recommend staying with 17 when possible.

After you install Tornadovm using the installer, you can recompile your projects from the terminal:

cd <TornadoVM-Root-Directory>
. source.sh
make graal-jdk-11-plus BACKEND=opencl,ptx

Hi, you followed :). Would it be correct to do this (after creating different sources):

$ cd <TornadoVM-Root-Directory>
$ . jdk17source.sh
$ make graal-jdk-17 BACKEND=ptx
$ mvn clean install

Lines 1-3, yes. Line 4 (mvn clean install) You don't need this. The make process will do it for you.
Note that the make build process is just more convenient for us to easy the configuration process. In reality, it is just a chain of scripts that link OpenCL, SPIRV and PTX configuration plus all paths needed for setup TornadoVM.

Lastly I want to ask about make in essence since you said

if you are using Graal):
make graal-jdk-11-plus BACKEND=ptx

is it only applicable with graal only asper would doing this:

$ cd <TornadoVM-Root-Directory>
$ . source.sh
$ make jdk-11 BACKEND=opencl ##make with just jdk-11?
$ mvn clean install

be considered illegal, thanks

What do you mean by illegal? As a rule? This is just a Makefile

For JDK 11 you use the jdk-11-plus rule

make jdk-11-plus BACKEND=opencl  ## Build with JDK >= 11

Thanks alot🔥

Hi again, I just wanted to ask about how I can make with graal-jdk-17.

$ make graal-jdk-17 BACKEND=ptx  
make: *** No rule to make target 'graal-jdk-17'.  Stop.  ##I am still getting this

So I took a look at the Makefile and noticed there’s no rule like that present

hi @54LiNKeR, you have to use the graal-jdk-11-plus rule in Makefile for any JDK version >= 11.
Try: $ make graal-jdk-11-plus BACKEND=ptx, it should work.

working… thanks🙏🏾
