pocketsphinx fails to cross build from source. One reason is that it
uses the build architecture pkg-config via AC_CHECK_PROG. The attached
patch replaces the use with PKG_PROG_PKG_CONFIG.
Another reason is that configure.ac decides that during cross
compilation, it should skip the gstreamer stuff (search for
AM_CONDITIONAL and BUILD_GST). Thus dh_install complains about missing
files. I think this upstream choice is unfortunate. I think upstream
should leave that choice to users (e.g. using an AC_ARG_WITH). Thus
users could enable it despite cross compilation. Do you think that would
work with upstream? It could look like:
AC_ARG_WITH(gstreamer, AS_HELP_STRING([--with-gstreamer],[Enable GStreamer
plugin, autodetect unless cross building]))
AS_IF([test "x$with_gstreamer" != xno],[
PKG_CHECK_MODULES(GStreamer, ..., HAVE_GST=yes, HAVE_GST=no)
AS_IF([test "x$with_gstreamer" = xyes && test "$HAVE_GST" = no],[
AC_MSG_ERROR(["gstreamer not found])])
])
AM_CONDITIONAL(BUILD_GST, test "x$with_gstreamer" != xno && test "$HAVE_GST" =
yes && { test "x$with_gstreamer" = yes || test "$cross_compiling" = no; })
Even after enabling BUILD_GST, the cross build fails, because
dh_gstscancodecs does not work during cross building (even though the
plugin was successfully cross built). We don't presently have a solution
to this.
Please consider applying the attached patch to fix the pkg-config issue.
Please consider talking to upstream and propose the --with-gstreamer
switch to allow cross building the gstreamer plugin and unconditionally
pass --with-gstreamer to the build if that was successful. Please close
this bug even if pocketsphinx fails in dh_gstscancodecs.
