    $ ./utils/docker-run make check-package
    package/pounce/Config.in:3: BR2_PACKAGE_LIBRESSL is part of a "choice" and should not be "select"ed

However, the situation is tricky: it seems that pounce does indeed
require libressl, and not libopenssl, because it really wants libtls.

In Buildroot, libopenssl and libressl are exclusive one to the other; we
then have two possible situations for a package:

  - works equally well with either libopenssl or libressl

  - only works with libopenssl

We have no way to represent this new case for pounce, which is:

  - only work with libressl.

So, the only solution is to actually depend on libressl:

    config BR2_PACKAGE_POUNCE
        bool "pounce"
        depends on BR2_PACKAGE_LIBRESSL
        [...]


    comment "pounce needs openssl support w/ libressl"
        depends on !BR2_PACKAGE_LIBRESSL

Unfortunately, for now, this is the only case, so we'll need a few other
cases before we look into providing a way to fore-se;ect libressl...

It is not an autotools package: the configure script is hand-written, so
it should not use the autotools infra.

The configure script calls pkg-config, so you need it in the
dependencies.

The configure script is not playing nice with cross-compilation: it
calls 'uname' to decide what to do, which is incorrect. It happens that
we are running on linux and targetting linux, so it works by accident.
We should however make sure that this is going to always be the case.

    POUNCE_DEPENDENCIES = host=pkgconf libressl

    define POUNCE_FAKE_UNAME
        $(Q)mkdir -p $(@D)/bin
        $(Q)printf '#!/bin/sh\necho Linux\n' >$(@D)/bin/uname
        $(Q)chmod 755 $(@D)/bin/uname
    endef
    POUNCE_POST_EXTRACT_HOOKS += POUNCE_FAKE_UNAME

    define POUNCE_CONFIGURE_CMDS
        cd $(@D) && \
        PATH=$(@D)/bin:$(BR_PATH) \
        ./configure \
            --prefix=/usr
    endef

    define POUNCE_BUILD_CMDS
        $(TARGET_CONFIGURE_OPTS) \
        $(TARGET_MAKE_ENV) \
        $(MAKE) \
            -C $(@D)
    endef

    define POUNCE_INSTALL_TARGET_CMDS
        $(TARGET_CONFIGURE_OPTS) \
        $(TARGET_MAKE_ENV) \
        $(MAKE) \
            -C $(@D) \
            DESTDIR=$(TARGET_DIR) \
            install
    endef

    $(eval $(generic-package))

Of course, totally untested... ;-)

Can you update, check, and respin, please?

Yann E. MORIN.
