flatpack Development

The flatpak manifest for flathub is at https://github.com/flathub/io.github.brunoherbelin.Vimix

To build the vimix flatpak with code from local folder (debugging), change the following:

{
    "name": "vimix",
    "buildsystem": "cmake",
    "config-opts": [
        "-DCMAKE_BUILD_TYPE=Release"
    ],
    "sources": [
        {
        "type":"dir",
        "path": "[your_development_dir]/vimix",
        }
    ]
}

Testing performance

Linux perf command

Allow perf on your system

sudo sysctl -w kernel.perf_event_paranoid=-1

Launch command to record

perf record ./vimix
perf record --pid=XXXXX

e.g.;

__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia   perf record --call-graph dwarf ./build/src/vimix

Analyse using https://github.com/KDAB/hotspot

Memcheck

To generate memory usage plots in massif format:

G_SLICE=always-malloc valgrind --tool=massif ./vimix

To check for memory leaks:

G_SLICE=always-malloc valgrind --leak-check=full --log-file=vimix_mem.txt ./vimix
