Geometryc Error: Unsupported file type *.obj

[JtePerson]

Geometryc Error: Unsupported file type .obj* So I finally successfully built bgfx osx-arm64 but when I went to try and convert a .obj file to a .bin using geometryc it threw an error saying that the input file was of an unsupported type even though the documentation and help command explicitly say that .obj files are supported. Also I don't think it's an error with the build because I built and ran the examples and my own main.cpp file and everything ran just fine with no problems

All I did to cause error Steps to reproduce the error:

1. build bgfx for osx-arm64
2. run geometryc with input file .obj and an output file .bin "./ExtLib/bgfx/.build/osx-arm64/bin/geometrycRelease -f ./meshes/.obj -o ./meshes/.bin"
3. then this was the entire output "Unsupported input file format './meshes/*.obj'"

Expected behavior To have geometryc generate a *.bin file for use in main.cpp

Additional context I am running everything on macOS with the bgfx build "osx-arm64" attempting run "geometrycRelease" with only input and output file flags. Sorry for the limited info but this is all the info I received when trying to run geometryc

You need to specify file name...

For example this should work: geometryc -f examples/assets/meshes/bunny.obj -o test.bin

Sorry for the misconception I was just being discreet about my file names, this was the exact command I typed to cause the error, "./ExtLib/bgfx/.build/osx-arm64/bin/geometrycRelease -f ./meshes/plane.obj -o ./meshes/plane.bin" and this was the only error message I got, "Unsupported input file format './meshes/plane.obj'"

Maybe its still something I'm doing though, is it maybe a problem with how blender generates .obj or .glb files?

Attach .obj file you have problem with.

Looks like the . in the file path is what causes the problem, because it seems to treat everything after the first period as an extension.

Where do you see multiple dots?

And yes, bx treats everything after first dot as extension: https://github.com/bkaradzic/bx/blob/2cebc558eb314e324f01ef05735551f234f5ea13/tests/filepath_test.cpp#L85

If you have /tmp/archive.tar.gz, path is /tmp/, filename is archive.tar.gz basename is archive, extension is .tar.gz

Ok thanks, for future reference though how might I go about solving this issue on my own and do you mind explaining what these different commands do?

[bkaradzic]

Ah I just realized maybe dot before slash causes the issue?!

[bkaradzic]

Nope, both work as expected:

geometryc -f examples/assets/meshes/bunny.obj -o test.bin

geometryc -f ./examples/assets/meshes/bunny.obj -o ./test.bin

Ok thanks, for future reference though how might I go about solving this issue on my own and do you mind explaining what these different commands do?

Can't really answer I still don't understand what's wrong with your command line.

Can you point out what fixed the issue for you?

[JtePerson]

Uh... not really, I attempted to run the command you said worked but it failed. Well it gave me a different error message but it was still the same "Unsupported file format" problem

[JtePerson]

Again sorry for the limited info, everything else compiles and runs including shaderc and geometryv so I don't fully understand why geometryc doesn't work

[JtePerson]

$ geometryc -f plane.obj -o plane.bin

Wait sorry I think I misread this, just to clarify the first line is the command and the following is the output?

[bkaradzic]

Yes, this is command line:

geometryc -f plane.obj -o plane.bin
