I am sorry for this, but maybe because I just moving to a new iMac with chip M1, after setup all the commands, I still have this error:

apple@Apples-iMac TinyEngine % brew install glew
Warning: glew 2.2.0_1 is already installed and up-to-date.
To reinstall 2.2.0_1, run:
  brew reinstall glew

I'm using the MINGW64 environment.

Hello,

Get the error

$ cd examples/9_Scene
$ make all
g++ -std=c++17 main.cpp -Wfatal-errors -O -I/usr/local/include -L/usr/local/lib -lTinyEngine -lX11 -lGL -lpthread -lSDL2 -lSDL2_image -lSDL2_mixer -lSDL2_ttf -lGLEW -lboost_system -lboost_filesystem -o main
$ ./main
Window could not be created! SDL_Error: Couldn't find matching GLX visual
Failed to launch visual interface.
Adres-eraro(nekropsio elŝutita) = "Segmentation fault" in esperanto

and

$ export SDL_VIDEO_X11_VISUALID=0x179
$ ./main
Adres-eraro(nekropsio elŝutita) = "Segmentation fault" in esperanto

for all examples on Fedora and Win11/WSL/Ubunutu Jammy. It seems something with the gui-system, I use wayland.

Greets and thanks for this program!

Hi!

Could you please tell me if iOS support is planned?

Thank you!

Hi, I wanted to test the engine so I tried to compile the examples and they won't because of the lambdas you are using, here is the image example when I try and compile it using g++ in manjaro (I'm pretty new to the Linux environment)

In file included from main.cpp:5: effects.h:9:25: error: non-local lambda expression cannot have a capture-default 9 | Handle interfaceFunc = [&](){ | ^ compilation terminated due to -Wfatal-errors.

Hey, I'm trying to use TinyEngine for a project because it looks really cool and useful, but I keep getting segmentation errors in when running the examples. Am I doing something wrong? Reading through the code it all seems like it should work.

I'm on MacOS.

For example, with the Heightmap example, I get a EXC_BAD_ACCESS (code=1, address=0x0) error due to this line:
mesh.bind<glm::vec3>("in_Position", &positions); //Bind Buffer to Property

Another example, when initiating a cube, I get pointed to the same error in the model helper. There seems to be something wrong in this line in void bind:
glBindVertexBuffer(bindings[binding], buf->index, 0, sizeof(T));

Do you know why this could be? Am I doing something wrong?

Hi, Tried to compile TinyEngine on Ubuntu 20.04 and got this error

make: *** [makefile:48: install] Error 1

I have modified the make file to install it in my $HOME since I don't want to spew files all over my file system. I have changed LIBPATH and INCLUDEPATH and changed line 23 to

@if [ ! -d "$(INCLUDEPATH)/TinyEngine" ]; then mkdir -p $(INCLUDEPATH)/TinyEngine; fi;

and line 65 to

@if [ ! -d "$(INCLUDEPATH)/TinyEngine" ]; then mkdir -p $(INCLUDEPATH)/TinyEngine; fi;

I don't think this is relevant since this error showed up when I tried to install with sudo without modifying the make file.

A bit unusual that the project requires root priveleges. Usually projects will build relative to the source tree in cwd. An install is a seperate step to perform once any vetting / audit is complete.
The easiest way to avoid the sudo might be to switch target from /usr/local to $HOME/.local - at least on relatively modern linux.
the files to modify would be

$ grep -rl "/usr/local" *

To change install target I ran:

find . -iname makefile -exec sed -i 's/\/usr\/local/\~\/.local/g' {} \;

To avoid errors caused by already-existing directories from previous run, i added "-p" to the mkdir

find . -iname makefile -exec sed -i 's/mkdir/mkdir \-p/g' {} \;

Then um, something something the linker needs to get pointed to ~/.local/lib without requiring overwriting of /etc/ld.so.cache

Not sure what the right way to do that is, sorry.
Maybe something like changing the link invocation

/TinyEngine/examples/0.0_Empty$ g++ -std=c++17 main.cpp -Wfatal-errors -O -I~/.local/include -L~/.local/lib/TinyEngine -lpthread -lSDL2 -lSDL2_image -lSDL2_mixer -lSDL2_ttf -lGLEW -lboost_system -lboost_filesystem -lX11 -lGL -o main

Cheers. Great project here.

hi @weigert
I am trying to make this awesome Engine works on macOS. I just download all required libraries and can run build all

I modify the makefile of each example to work in macOS like bellow

TINYLINK = -lpthread -lSDL2 -lSDL2_image -lSDL2_mixer -lSDL2_ttf -framework OpenGL -lGLEW -lboost_system -lboost_filesystem

(Remove -lX11 and replace -lGL with -framework OpenGL)

Then I can compile and run example 1
With example 2, I have this error:

4.1 ATI-4.5.14
Linker Error: ERROR: 0:1: '' :  version '130' is not supported
ERROR: 0:2: '' :  #version required and missing.

Linker Error: ERROR: 0:1: '' :  version '130' is not supported
ERROR: 0:2: '' :  #version required and missing.

If you want I can create PR after all examples run on MacOS! Thank you in advance!

Success

Your Makefile works out of the box. You only have to create ~/.local directory before running make.

There is an warning I think I should report back to you:

(and as someone mentioned in another issue, -lnoise has to be removed from 5_Particles makefile)
