These apps are designed with a simple goal in mind: to make meaningful, structured content more accessible, whether you’re studying theology or improving your English vocabulary. 📱 Now Available on Both Platforms All apps are live and available for download: Google Play Developer Page: https://play.google.com/store/apps/dev?id=5835943159853189043 Apple App Store Developer Page: https://apps.apple.com/ca/developer/q-z-l-corp/id1888794100 📖 Theology & Confession Study Apps For those interested in Reformed theology and classical Christian teachings, I’ve developed a series of apps that present foundational texts in a clean, focused reading format: The Belgic Confession Canons of Dort Heidelberg Catechism Westminster Shorter Catechism Each app is designed to provide a distraction-free experience, making it easier to read, reflect, and revisit these im...

For correct functionality when running under Wayland you must use the latest versions of all the EFL components under Wayland. As a precursor to these steps you must have downloaded and compiled Wayland as per the building instructions . example codes // gcc -o eglwayland eglwayland.c `pkg-config --cflags --libs wayland-egl egl glesv2` #include <stdlib.h> #include <stdint.h> #include <stdio.h> #include <string.h> #include <wayland-client.h> #include <wayland-server.h> #include <wayland-client-protocol.h> #include <wayland-egl.h> // Wayland EGL MUST be included before EGL headers #include <EGL/egl.h> #include <EGL/eglplatform.h> #include <GLES2/gl2.h> struct _escontext { /// Native System informations EGLNativeDisplayType native_display; EGLNativeWindowType native_window; uint16_t window_width, window_height; /// EGL display EGLDisplay display; /// EGL context EGLContext context; /// EGL surfac...

For correct functionality when running under Wayland you must use the latest versions of all the EFL components under Wayland. As a precursor to these steps you must have downloaded and compiled Wayland. Setting up the environment apt install git autoconf automake libtool autopoint check Installing in a custom location, system wide install would break things. export WLD=$HOME/install # change this to another location if you prefer export LD_LIBRARY_PATH=$WLD/lib export PKG_CONFIG_PATH=$WLD/lib/pkgconfig/:$WLD/share/pkgconfig/ export PATH=$WLD/bin:$PATH export ACLOCAL_PATH=$WLD/share/aclocal export ACLOCAL="aclocal -I $ACLOCAL_PATH" mkdir -p $WLD/share/aclocal # needed by autotools Do not set LD_LIBRARY_PATH as your default, it will break things. Put the above in a script env.sh and source it in the terminal you wish to build the packages. libdrm sudo apt-get install xutils-dev libpciaccess-dev git clone https://anongit.freedesktop.org/git/mesa/drm cd drm/ sour...

fix error: wl_display@1.error(wl_display@1, 1, "invalid arguments for wl_surface@6.attach")

By -
wl_display@1.error(wl_display@1, 1, "invalid arguments for wl_surface@6.attach") root cause： wl_surface_attach(wl_surface* surface, wl_buffer* buffer, int, int); ((wl_proxy*)surface)->display != ((wl_proxy*)buffer)->display surface's display and buffer's display were not matched. wayland server can't find the buffer object in surface's client connection. solution: correct source code, let wl_surface and wl_buffer use the same display. By the way, each time you call wl_display_get(NULL). you will get a new display.
