problemn building pc_simulator

[Kephas3]

Hi,

After reading and even following the tutorial in the LVGL course to install the simulator on Ubuntu 22.04.3 , i encountered the following issue.

It happens that, even after building a first time, the folder Debug doesn't appear
it finally appeared after creating the configuration in Run/Debug Settings, but the folder doesn't contain the pc_simulator_sdl_eclipse file.

Thank's for your help

Which version do you use? I've just pushed a fix to the master branch.

To solve it you need to remove png from project porpeties:

Also i 've tried first to run it on OSX 13.4.1, but an error showed me the following

clang : error : the clang compiler does not support =pg option on version of OSX 10.9 and later

Best regards

[kisvegabor]

I've just fixed it in LVGL 🙂
Please update the master branch.

Just did a new clone (git clone --recursive https://github.com/littlevgl/pc_simulator_sdl_eclipse.git), got this on mac os:

clang: error: the clang compiler does not support -pg option on versions of OS X 10.9 and later

[gjvanderheiden]

If I try project properties-> C/C++ Build -> Tool Chain Editor -> Current toolchain: MacOSX GCC (instead of Cross GCC) is compiles.

CMake seams to work without editing, apart from 2 compile errors (just do what the compiler suggests) in LVGL itself.

@gjvanderheiden I confirm, it also works for me

Thank's a lot ! ;)
