Probleme with dependecies convert ressources [ SOLVED ]

I get this error when in try to check if the project i just created works.

Couldn't find NVIDIA Texture Tools
Processing directory: apps_dev/lukeVideoLowPoly

I run on the onboard intel chip quite happily on my laptop.

Ok did a little search for Nvidia tools Blend4web and found this on GitHub

  missing_progs = get_missing_progs(dependencies)
    if "ffmpeg" in missing_progs and not "avconv" in missing_progs:
        index = missing_progs.index("ffmpeg")
        del missing_progs[index]
    if "avconv" in missing_progs and not "ffmpeg" in missing_progs:
        index = missing_progs.index("avconv")
        del missing_progs[index]
    needed_progs = {}
    for dep in missing_progs:
        if dep == "avconv" or dep == "ffmpeg":
            needed_progs["Libav or FFmpeg"] = True
        elif dep == "identify" or dep == "convert":
            needed_progs["ImageMagick"] = True
        elif dep == "nvcompress":
            needed_progs["NVIDIA Texture Tools"] = True
        elif dep == "qt-faststart":
            needed_progs["Qt-faststart (optional)"] = True
    for prog in needed_progs:
        print("Couldn't find", prog)
    if len(missing_progs) > 0:
        return False

One will notice that other libraries are tried first for example imagemagick. So i installed it and it WORKS AGAIN !


That's another one to look for one fresh instals…

Have a great day.

Hi Luke,

One will notice that other libraries are tried first for example imagemagick. So i installed it and it WORKS AGAIN !

Indeed there is the need to install some dependencies on Linux. We should make some instructions for advanced users.

i had similar issues on fresh fedora installs.
ffmpeg requires rpm fusion enabled

dnf install libavc1394-devel.x86_64
dnf install nvidia-texture-tools-devel.x86_64
dnf install ffmpeg

Done !
