[Buildroot] [PATCH v6 1/1] package/nodejs: use system-icu for host-nodejs

[Yann E. MORIN]

James, All,

On 2020-07-27 03:49 -0600, James Hilliard spake thusly:
> The nodejs configure.py file orders zlib headers before the bundled ICU
> headers. The zlib headers happen to be located in the system include
> directory, next to some system ICU headers (not bundled). If these are
> built before nodejs is, nodejs will get confused and try to use the
> system ICU headers instead of the bundled ones.
> 
> Fix this by always using host-icu.
> 
> Set CXXFLAGS.target to -DU_DISABLE_RENAMING=1 when building with
> system-icu since host-icu is built with --disable-renaming.

Why did you need to introduce HOST_NODEJS_CONF_OPTS? Can't we just
change --with-intl where it already is?

You forgot to propagate HOST_CXXFLAGS.

Why do we use CXXFLAGS.target but LDFLAGS.host ?
