Re: Linking error in headless(--without-x) build

===== SOLVED =====

I was able to fix it myself.

For fixing linking error you need to edit "vcl/Library_vcl.mk"

==============Before=====================
ifeq ($(ENABLE_HEADLESS),TRUE)
$(eval $(call gb_Library_add_exception_objects,vcl,\
$(vcl_generic_code) \
    vcl/unx/generic/printer/jobdata \
    vcl/unx/generic/printer/ppdparser \
    vcl/null/printerinfomanager \
    vcl/headless/headlessinst \
))

$(eval $(call gb_Library_use_externals,vcl,\
fontconfig \
freetype \
))
endif
======================================

=============== After ================
ifeq ($(ENABLE_HEADLESS),TRUE)
$(eval $(call gb_Library_add_exception_objects,vcl,\
$(vcl_generic_code) \
    vcl/unx/generic/printer/jobdata \
    vcl/unx/generic/printer/ppdparser \
    vcl/null/printerinfomanager \
    vcl/headless/headlessinst \
    $(vcl_headless_code) \
    $(vcl_headless_freetype_code) \
))

$(eval $(call gb_Library_use_libraries,vcl,\
basebmp \
))

$(eval $(call gb_Library_use_externals,vcl,\
fontconfig \
freetype \
))
endif

======================================

You also need to add "basebmp" entry because later you would get linking
error again because "vcl/headless/svpbmp.cxx" is using "basebmp".


After this you would get few other errors as

ERROR: Removing file ui-previewer from file list.
: ERROR: Removing file shell_scripts_gnome.filelist from file list.
: ERROR: Removing file shell_scripts_kde.filelist from file list.
: ERROR: Removing file shell_scripts.filelist from file list.

Since you don't need these in headless so delete these entries from
"workdir/InstallScriptTarget/setup_osl.ins"
similar to
