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

Yes, I’ve already done that but it didn't help. I also added make.exe, ruby.exe, and TouchGFXDesigner-4.25.0.exe to the exclousion process list.

I found a temporary workaround for the delay when running the "Generate Assets" step in TouchGFX Designer.

By default, the command looks like this:

make -f simulator/gcc/Makefile assets -j8

I changed it to:

make -f generated/simulator/gcc/Makefile assets -j8

With this change, asset generation starts immediately, without any noticeable delay.
This isn't a full fix, but it may help others who are facing the same unexplained slowdown during asset generation.

Hello @JureL,


Can you try without the "-j8" or with "-j4" and with "-d" to see if it keep hangs ?

Hi @LouisB 
I tried it but there is no change it hangs at the exact same line for both cases (without -j8 or with -j4).

Hi everyone,
Yesterday I just found a fix to this issue which is quite strange, but it looks like the problem is gone.
Turns out the fix was simple:
Go to Control Panel → User Account Control Settings
Set it from Never notify → to Always notify
Then set it back to Never notify
After doing this, asset generation in Designer works fast again.
No idea why it helps, but it does. Hopefully this helps someone else.
