Now i keep gettings following error after ./configure:

configure: error: Package requirements (tss2-esys) were not met:

No package 'tss2-esys' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables TSS2_ESYS_CFLAGS
and TSS2_ESYS_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

You may need to set PKG_CONFIG_PATH if your tpm2-tss is installed in a non-standard path for your distro, or indeed update to a version of tpm2-tss which provides the ESAPI (added in version 2.0)

What should PKG_CONFIG_PATH variable contain? Could you please provide an example? I am on Ubuntu 18.10 (4.18.0-13-generic).

Thanks

Per the README help requests are better handled on the mailing list: https://lists.01.org/mailman/listinfo/tpm2

It's likely that your system's default install location isn't included in the default PKG_CONFIG_PATHs. You should find where tpm2-tss was installed to (possibly /usr/local/lib) and add the pkgconfig subdirectory of that location to PKG_CONFIG_PATH, i.e.

PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./configure

@williamcroberts I think this should be part of the README.md of tpm2-tools, especially for people who want to use latest master of tpm2-tss OR run from source rather than packaging system

PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./configure

I just ran into this and had to end up in this issue to be reminded about why my pkgconfig is not working as expected. I know it is silly when you do it every day, but we shall not assume people do this everyday and have this knowledge ;)

This is actually distro dependent since they configure what the default pkg-config paths are. You can actually check by doing:
pkg-config --variable=pc_path pkg-config and it shows what the configuration is. This is very much an autoconf/autotools/pkg-config mystery thing, I am OK with adding it, just submit a patch to the proper documentation you want it in.
