Hi,
Since a while I am trying to build libreoffice with yocto [1][2]
cross-build system for my embedded devices.
When building with yocto there are two temporary sysroots: One native
for all the binaries run on build host during build and one for the
cross target to link against the libraries.
What causes me trouble for a while is native saxparser.
Native build means:
* configure with
--enable-debug \
--enable-dbgutil \
\
--enable-python=system \
--without-x \
--with-system-curl \
--with-system-boost \
--without-boost-date-time \
--without-boost-iostreams \
--without-boost-system \
--with-system-icu \
--with-system-expat \
--disable-postgresql-sdbc \
--disable-lotuswordpro \
--disable-firebird-sdbc \
--disable-liblangtag \
--disable-openssl \
--disable-gltf \
--disable-collada \
--disable-scripting-beanshell \
--disable-scripting-javascript \
--disable-graphite \
--disable-pdfimport \
--disable-orcus \
--disable-coinmp
* compile by something like (inspired by make target cross-toolset)
make -f Makefile.gbuild build-tools
* install all binaries an their libs manually into native sysroot
From what I've seen so far there are many binaries used during cross
build seem to work as expected.
saxparser fails with (patch attached causing more detailed error message)
ERROR: component context fails to supply service
'com.sun.star.xml.sax.Parser' of type 'com.sun.star.xml.sax.XParser'
I have no idea whether and---if yes---why your procedure differs from
normal LibreOffice cross-compilation scenarios.
Anyway, the dependencies for running saxparser during the build are
listed in the gb_Executable__register_saxparser define in
RepositoryExternal.mk:
# FIXME ure/services.rdb needs cleanup
# The dependencies on ure/services.rdb and udkapi.rdb are implicitly required
# due to the settings for URE_SERVICES and URE_TYPES in cppuhelper/source/unorc:
# FIXME: the library target should be for build too
define gb_Executable__register_saxparser
$(call gb_Executable_add_runtime_dependencies,saxparser,\
$(call gb_Library_get_target,$(gb_CPPU_ENV)_uno) \
$(call gb_Package_get_target_for_build,instsetoo_native_setup_ure) \
$(call gb_Rdb_get_target_for_build,saxparser) \
$(call gb_Rdb_get_target_for_build,ure/services) \
$(INSTROOT)/$(LIBO_URE_MISC_FOLDER)/services.rdb \
$(call gb_UnoApi_get_target,udkapi) \
)
endef
So what you need to have is (the cross-build equivalents of the "normal"
locations of):
instdir/program/libgcc3_uno.so
instdir/program/unorc
workdir/Rdb/saxparser.rdb
instdir/program/services.rdb (a copy of workdir/Rdb/ure/services.rdb)
instdir/program/types.rdb (a copy of workdir/UnoApiTarget/udkapi.rdb)
(The last two are referenced from instdir/program/unorc as UNO_SERVICES
and UNO_TYPES, respectively.) Then, in the i18npool_LD_RULE in
i18npool/CustomTarget_localedata.mk, the -env:LO_LIB_DIR and
-env:URE_MORE_SERVICES command line arguments must reference (the
cross-build equivalents of the "normal" locations of) the
instdir/program/ directory and workdir/Rdb/saxparser.rdb, respectively.
