Any guide to build without dependencies like opengl/curl?

[ChipZhang]

I want to make a linux build without external dependencies like opengl/curl/webkit, so it only depends on GTK.
There is a cmake option NAPPGUI_WEB to toggle webkit support, but no such options for opengl/curl.

Hi @ChipZhang!
Now the only way in removing src/inet;src/ogl3d from CMakeTargets.cmake. You also have to remove the examples that depend on these libraries.

But will be nice to have some flag similar to NAPPGUI_WEB. Leave this issue open, please.

Hi Fran! Been too long.... been busy to say the least. I have the same question, I think you've answered it but wanted to double check with you first. Just did a pull of your latest in my old napp directory where we did some webview stuff (that's how long it's been since I've had time to get back to NApp work....) and tried to build. I get the same type of dependency error on MacBook Pro M1... is the best option for me as you noted above? Remove the reference and the demo apps from the build files?

Hi @d33p-dev
That's strange. OpenGL support is available on all macOS versions (including Tahoe). Try using CMake 4; CMake 3 might not be compatible with the latest versions of Xcode.

The OpenGL support compile/run without problems on all versions of macOS.

Yeah for some reason my ogl libraries / mac sdk files were in a different directory than I think we're expected. I asked claude and we got it to run by using "Unix makefiles" option and then supplying the exact directory.... It's a "my machine/user error" situation. Like normal.
