package/gutenprint/0001-use-pregen-xmli18n-header.patch

   1 src/xml: use preg-gen xmli18n_tmp.h if specified
   2
   3 Ideally, the programs needed at build-time should be built with
   4 CC_FOR_BUILD, and not with CC_FOR_HOST.
   5
   6 Unfortunately, this program wants to link against the gutenprint libs,
   7 so we would also need to build them with CC_FOR_HOST, that is build them
   8 twice, once for build, once for host.
   9
  10 Instead, in the Buildroot context, we first build gutenprint for the build
  11 system, use that to generate the incriminated header, and then re-use that
  12 header to build the gutenprint for the host.
  13
  14 It is not possible to have such constructs in Makefile.am:
  15     ifeq ($(FOO),)
  16     bar: bla
  17         cat $< >$@
  18     else
  19     bar:
  20         echo $(FOO) >$@
  21     endif
  22
  23 as autoreconf will yell loudly that there is an 'endif' without an 'if'.
  24 Sigh... :-(
