Hello Allan,

Thanks for contributing this package!

Should be just a tab.

Presumably you need to select BR2_PACKAGE_ICU here.

Don't you need to have Python as a dependency to build this ?

BOOST_FILE_VERSION=$(subst .,_,$(BOOST_VERSION))

I'd prefer to rely on make/shell only rather than using Perl here.

Note that you can also write:

BOOST_WITHOUT_FLAGS += $(if $(BR2_PACKAGE_BOOST_IOSTREAMS),iostreams)

> +ifeq ($(BR2_ENABLE_DEBUG),y)
> +BOOST_VARIANT=debug
> +else
> +BOOST_VARIANT=release

and

BOOST_VARIANT = $(if $(BR2_ENABLE_DEBUG),debug,release)

> +BOOST_WITHOUT_FLAGS_COMMASEPERATED = $(shell echo $(BOOST_WITHOUT_FLAGS) | tr ' ' ',')

Maybe this can be done with a make $(subst ...) call.

Could you expand a bit on why a gcc wrapper is needed here ? A comment
above the CONFIGURE_CMDS about this would be great.

This install to staging, so it should be in BOOST_INSTALL_STAGING_CMDS,
and you should set BOOST_INSTALL_STAGING=YES at the top of your package.

Not needed, everything in $(TARGET_DIR)/usr/include is removed.

Not needed, all binaries are automatically stripped.
