Subject: build: Conditionally adjust VALAFLAGS in case of proper bootsrapped builds
X-Git-Tag: 0.35.1~71
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fbc749bd4ec84673ace5b311ec468c75ab049e1f;p=thirdparty%2Fvala.git

build: Conditionally adjust VALAFLAGS in case of proper bootsrapped builds

This adds --hide-internal to VALAFLAGS to allow symbols to be marked
'internal' in Vala source files and not appear in the dynamic symbol table
of libvala.

The build system checks for minimum valac version to fullfill required
support of needed VALAFLAGS.
