From 9169810a9bd97c99d8b7a0e8aadabdcca3883e99 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Tue, 27 Aug 2013 19:08:04 +0200 Subject: [PATCH] neon: replace 'choice' for XML library with two options The NEON library can either be compiled without XML support, with XML support provided by Expat, or with XML support provided by libxml2. Until now, to represent this, a Kconfig 'choice..endchoice' was used. Unfortunately, another package cannot 'select' one of the possible choices. So for example, a package such as 'rpm', or the to-be-added 'subversion' package could not select their dependencies, they had to do a 'depends on !BR2_PACKAGE_NEON_NOXML', which is not how Buildroot handles library dependencies in general. So, this commit replaces the 'choice...endchoice' block with simply two configuration options that are mutually exclusive. The option names are not changed, so no Config.in.legacy addition is needed. An hidden option BR2_PACKAGE_NEON_XML is provided, so that packages that need XML support in NEON but don't care whether it's provided by Expat or libxml2 can simply select BR2_PACKAGE_NEON_XML. The rpm package is updated accordingly.
