You need to add exceptions to build a lot GPLv3 components but not let them
be part of product images.
In distro config:
INCOMPATIBLE_LICENSE += "GPLv3 GPLv3+ LGPLv3 LGPLv3+"
...
WHITELIST_GPL-3.0 += "bash"
PACKAGE_EXCLUDE += "bash-ptest bash-dbg bash-staticdev bash-dev bash-doc
bash-locale bashbug bash"
...
The PACKAGE_EXCLUDE must be complete list of binary packages produced by the
recipe.
I end up enabling a large set of GPLv3 tools for use as development tooling at
build
time or in SDK:
$ grep WHITELIST_ distro.conf
WHITELIST_GPL-3.0 += "autoconf"
WHITELIST_GPL-3.0 += "bash"
WHITELIST_GPL-3.0 += "bc"
WHITELIST_GPL-3.0 += "binutils"
WHITELIST_GPL-3.0 += "bison"
WHITELIST_GPL-3.0 += "ccache"
WHITELIST_GPL-3.0 += "coreutils"
WHITELIST_GPL-3.0 += "diffutils"
WHITELIST_GPL-3.0 += "elfutils"
WHITELIST_GPL-3.0 += "findutils"
WHITELIST_GPL-3.0 += "gawk"
WHITELIST_GPL-3.0 += "gdb"
WHITELIST_GPL-3.0 += "gdbm"
WHITELIST_GPL-3.0 += "gettext"
WHITELIST_GPL-3.0 += "gnutls"
WHITELIST_GPL-3.0 += "grep"
WHITELIST_GPL-3.0 += "libevent"
WHITELIST_GPL-3.0 += "libpipeline"
WHITELIST_GPL-3.0 += "libunistring"
WHITELIST_GPL-3.0 += "m4"
WHITELIST_GPL-3.0 += "make"
WHITELIST_GPL-3.0 += "readline"
WHITELIST_GPL-3.0 += "rsync"
WHITELIST_GPL-3.0 += "sed"
WHITELIST_GPL-3.0 += "which"
If one does not do this, alternative is to use a bunch of old and deprecated
tool
versions from meta-gplv2.
Hope this helps,
