[Buildroot] Problem adding a new package tpm2-tss-engine

[Marie Maurer]

Hello,

I am just trying to add a package tpm2-tss-engine.

I found build instruction here:

https://github.com/tpm2-software/tpm2-tss-engine/blob/master/INSTALL.md

I can build locally. Now I wanted to add this as buildroot package.

What I have done so far:

Config.in

config BR2_PACKAGE_TPM2_TSS_ENGINE
             bool "tpm2-tss-engine"
             depends on !BR2_STATIC_LIBS # tpm2-tss
             depends on !BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_ARM # glibc < 2.20
             select BR2_PACKAGE_LIBQRENCODE
             select BR2_PACKAGE_TPM2_TSS
             help
               The tpm2-tss-engine project implements a cryptographic engine
               for OpenSSL for Trusted Platform Module (TPM 2.0) using the
               tpm2-tss software stack that follows the Trusted Computing
               Groups (TCG) TPM Software Stack (TSS 2.0). It uses the
               Enhanced System API (ESAPI) interface of the TSS 2.0 for
               downwards communication.
               It supports RSA decryption and signatures as well as
               ECDSA signatures.

comment "tpm2-tss-engine needs a toolchain w/ dynamic library"
             depends on BR2_STATIC_LIBS
             depends on !BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_ARM

$(eval $(autotools-package))

So far so good. It is downloading the package, calls bootstrap, which is part of the downloaded package.
Inside file bootstrap there is a call to autoreconf. The command autoreconfig is not found.

How do I solve this? Do I need some dependency that I want to used autoreconf?

Searching for autoreconf I find the following:

marie at 2020L009:~/buildroot-2020.08-rc1/buildroot-2020.08-rc1$ find . | grep autoreconf
./output/build/host-autoconf-2.69/bin/autoreconf

BTW: I am using raspberrypi3_defconfig for testing my changes.

Many thanks!

Best regards,

Marie
