Error when generating code in GUI Guider

[filo96]

Hi,

I'm using GUI Guider 1.5.1-GA.

In my PC (Windows 11) I'm able to generate the code of the given examples in GUI Guider. However, in a project we are developing, I'm not able to generate the code anymore.

I got a list of Java errors:

I encounter this problem only in my PC. When I use another PC with Windows 11 andh the same project it works well.

I attach both the logs when GUI Guider creates the code correctly and when it doesn't.

I noticed that the two log are very different.. Also, when it doesn't work, it seems to generate correctly the C code, but when it switches to MicroPython code it loops the same images for about 30 times (and it shouldn't do this)!

Other infos: I tried to uninstall and re-install both GUI Guider and Java in their latest version, but it doesn't solve anything.

Thank you for your reply @LiubinGong !

We are not able to run the C simulator due to problems related to the 32k limit of the Windows command line.

This is why we'd like to use the MicroPython simulator.

However I've been able to solve the problem! I installed the last version of JAVA JDK and the problem has instantly disappeared!

I didn't know that JDK is required. Also, the other examples were working without JDK installed!

Here my versions of java:

C:\Users\user>java --version
java 20.0.1 2023-04-18
Java(TM) SE Runtime Environment (build 20.0.1+9-29)
Java HotSpot(TM) 64-Bit Server VM (build 20.0.1+9-29, mixed mode, sharing)

C:\Users\user>javac --version
javac 20.0.1

[ I'm happy to read that Java will be removed for the next version of GUI Guider ]

Hi Filo96

    According to the log analysis, it should be that converting images consumes too much memory when generating MicroPython code.

We currently support the win10 version, So some unknown issues in all win11 without verification.

I have a workaround method, you can click "run->simulator->c" instead of "generated code". This will only generate C code and run the simulator.

BTW,  Version 1.6.0 will be released at the end of July. it will no longer depend on Java.
