TouchGFX Designer 4.25.0 – extremely slow asset generation (make assets takes 5+ minutes)

Hi everyone,

I'm experiencing a very frustrating issue with TouchGFX Designer version 4.25.0.

Whenever I click "Generate Code", the process hangs for several minutes (up to 5 minutes) at the step:
make -f simulator/gcc/Makefile assets -j8.

This used to work quickly in the past with the same version on the same PC, but the issue suddenly started recently without any apparent changes.
I'm running Windows 11, and this problem affects all projects, even the official TouchGFX examples.

Here’s what I’ve tried so far (none of which helped):

  • Disabled antivirus and security software completely
  • Completly remove and reinstall TouchGFX Designer
  • Run the Make command manually from the TouchGFX environment terminal – the issue presist
  • Tested the same project on another (slower) PC – and it works fine there

I use TouchGFX on a daily basis, so this issue is really slowing down my workflow.

Has anyone else experienced this?
Any advice would be highly appreciated!

Best regards,
Jure

Does this happen in case when all assets are already generated ?

I tried asset generation in msvs and the generation is quick without any delays.

VERBOSE=1 did not output any aditional informations so instead I tried:

make -f simulator/gcc/Makefile assets -j8 --debug=b


Here is the log - It stops at line 35:

 This issue happens in both cases even if the assets are already generated.

@ferro 
project path is default example path: c:\TouchGFXProjects\MyApplication_1\.
Also the project is empty application:

Frustrating. Maybe try to install version 4.24.1 in parallel ? You said you tried other versions but not sure if multiple at the same time.

Just tested it on my Windows 11 PC. Builds in seconds.

Have you checked your environment variables?

Maybe something with hidden files in folders ?

I had 5 versions in parallel but none of them worked. The exact same delay happend in every version. To make sure I installed version 4.24.1 again and tried generating assets at the same time in 4.25.0 and 4.24.1 but still no change.

I checked and none of the files or folders are hidden.

Yes, I verified the environment variables to ensure that TouchGFX is using the correct version of make from its own toolchain, not some other version that might be installed globally on the system (e.g. from MSYS2 or another toolchain). Everything appears correctly set up.

And did you try add project folder to this list ?

And add your folder
