Hi,
We saw something else on 2.6.18+ kernel versions, related to the modpost
utility not including the required header files into the generated .c
file. That is likely the cause of the problem you are seeing.
To workaround this issue, can you try the following:
In file /dsplink/make/Linux/Davinci/link.mk:
Search for CMD_MODPOST and update the code. Make sure you convert spaces
to tabs all the rules below.
$(target_deb):
$(CMDECHO)$(DISPLAY) Generating $(basename $@)...
$(CMDECHO)$(COPYFILES) "$(PROJ_INCLUDE)"
"$(EXPORT_INC_PLATFORM)" > $(TRASH)
$(CMDECHO)$(CMD_LINK) $(LD_SW_OUT)$(DRIVER_DEB) $(foreach dir,
$(ARGS_ARCH_DEB), $(wildcard $(dir)/*.o)) $(USR_LIBS_DEB)
$(CMDECHO)$(DISPLAY) Post processing kernel module $(basename
$(basename $@))...
$(CMD_MODPOST) $(DRIVER_DEB)
$(CMDECHO) echo "#include <linux/autoconf.h>" >$$.tmp
$(CMDECHO) echo "#include <linux/spinlock.h>" >>$$.tmp
$(CMDECHO) cat $(MOD_FILE_DEB) >> $$.tmp
$(CMDECHO) cat $$.tmp > $(MOD_FILE_DEB)
$(CMDECHO) rm -f $$.tmp
$(CMDECHO)$(COMPILER) $(CC_SW_DEB) $(STD_CC_FLAGS)
$(USR_CC_FLAGS) $(STD_CC_DEFNS) \
$(USR_CC_DEFNS) -DDDSP_DEBUG
-DKBUILD_BASENAME=$(basename $(basename $@)) -D"KBUILD_STR(s)=#s" \
-c -o $(MOD_FILE_DEBOBJ) $(MOD_FILE_DEB)
$(CMDECHO)$(LD) $(STD_AR_FLAGS) $(LD_SW_RELOC) $(LD_SW_OUT)
$(MOD_FILE_DEBKNL) $(DRIVER_DEB) $(MOD_FILE_DEBOBJ)
$(CMDECHO)$(COPY) $(MOD_FILE_DEBKNL) $(BUILD_EXPORT_DEB)/.
drvdeb : $(target_deb)
$(target_rel):

Hope this helps ...

Subject: DSPLINK building problems with GIT 2.6.23 kernel
Hi All.
Sorry for repeating questions about dsplink...
I use dvevm_1_20 and dsplink_1_30_82_02 and GIT kernel 2.6.23.
When I compiled dsplink and cmem_1_02, cmem_1_02 compiled OK and apitest
program worked fine.
But in case of dsplink, the errors occurred.
I already applied Kevin's patch files.
But Same errors are NOT deleted...
Could anyone help this problems?
