2016-01-14Fix XORG_WITH_XMLTO to work with xmlto >= 0.0.27Andreas Boll
Starting with xmlto version 0.0.27 the return code of xmlto --skip-validation txt conftest.xml is non-zero if conftest.xml is an empty file. As a consequence the macro XORG_WITH_XMLTO returns "xmlto cannot generate text format, this format skipped" and therefore libraries like libxi, libxdmcp and others won't convert docbook XML to text format. This changed behavior was introduced with the following change in xmlto: xmlto.in: use correctly exit code from xsltproc See also: https://fedorahosted.org/xmlto/changeset/77 This patch fixes this by additionally testing xmlto with a non-empty XML file. More details can be found at: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=613674 Thanks to Peter Pearse, Helmut Grohne and Gaetan Nadon. v2: To maintain compatibility with older xorg tarballs don't replace the original test with the empty XML file but instead add a fallback to additionally test with a non-empty XML file if the original test fails. Use the alternate solution with <x></x> to skip compatibility issues with different docbook versions.

2014-03-27XORG_PROG_RAWCPP: Add TRADITIONALCPPFLAGSHans de Goede
In some cases we may want to have -traditional for proper whitespace preserving without -undef, as we actually want the system definitions to be in place so we can #ifdef on them. IE in xinit various .cpp files contain things like #ifdef __APPLE__ and #ifdef __linux__ So this patch adds a TRADITIONALCPPFLAGS variable which contains just -traditional where applicable without the other RAWCPPFLAGS for unsetting the system definitions.

2013-08-26Use the right variable names for the compiler flags in XORG_TESTSET_CFLAGChris Wilson
Whilst populating the xorg_cv_ cache entries, and the subsequent xorg_testset_, we always include the FLAG_PREFIX in the name, to distinguish between C and C++ iterations. However, in the body of the test function, we dropped the FLAG_PREFIX expansion and so always used the empty string and hence did not correctly detect incorrect flags.

If XORG_COMPILER_FLAGS is called more than once with separate languages, the unknown warning options used internally for unknown warning checking will be set the first time and then the cached value will be used for subsequent languages. This is a problem if the compilers differ between the languages. This change ensures that the unknown warning options are namespaced so multiple XORG_COMPILER_FLAGS calls with different languages are checked separately.

Adding this feature is motivated by a bug in fop 0.95 where fop crashes in the presence of some characters like the latin capital sharp s. Fop version 1.0 works correctly. This is the same feature found in XMLTO and the likes. In the macro public interface there is a shift in parameter position for the DEFAULT parameter. Doing development on older libraries (point releases on older versions) will still work the same way as the "no" value will be interpreted as the minimum version.
