error while building

[StefanoSetti]

during the compilation process of library tss-esapi = "6.1.1" an error occurred:

failed to run custom build command for `tss-esapi-sys v0.2.0`
...
cause by:
...
thread 'main' panicked at 'Failed to find tss2-sys library.:

what should I do?

[Superhepper]

Have you installed the tpm2-tss library?

[StefanoSetti]

in my OS?

[Superhepper]

@ionut-arm is better at answering these types of questions. But I think you need to have the tpm2-tss library installed on the machine where you build the code, but also on the machine where you run the code.

[StefanoSetti]

in both cases the lib is installed

[Superhepper]

Hrmm maybe it is pkg that have problem finding it.

[ionut-arm]

Indeed, you should be able to check using pkg-config. What does the following output? (you might need to install pkg-config)

pkg-config --modversion tss2-esys

[StefanoSetti]

Package tss2-esys was not found in the pkg-config search path.
Perhaps you should add the directory containing `tss2-esys.pc'
to the PKG_CONFIG_PATH environment variable
Package 'tss2-esys', required by 'virtual:world', not found

I'm using fedora and pkgs tss2 and tss2-devel are installed

[ionut-arm]

Looking at our Fedora test Dockerfile, seems you might need tpm2-tss-devel?

[StefanoSetti]

pkg-config --modversion tss2-esys
3.1.0

it look slike to work now.

[ionut-arm]

I hope it will work - technically speaking we support versions 2.3.3 and up (and we do run tests on the CI against that version, in the Fedora container), but if anything starts failing with weird errors let us know.

[StefanoSetti]

Ok,I will

[StefanoSetti]

It works!
