Re: Can I also generate other outputs of gcc when build?


However, I have done it by add make steps to the "\packages\pkgconf\rules.mak". Such as:

%.o.d : %.c
ifeq ($(HOST),CYGWIN)
@mkdir -p `cygpath -w "$(dir $@)" | sed "s@\\\\\\\\@/@g"`
else
@mkdir -p $(dir $@)
endif
$(CC) -c $(INCLUDE_PATH) -I$(dir $<) $(ACTUAL_CFLAGS) -Wp,-MD,$(@:.o.d=.tmp) -E -o $(dir $@)$(OBJECT_PREFIX)_$(notdir $(@:.o.d=.i)) $<
$(CC) -c $(INCLUDE_PATH) -I$(dir $<) $(ACTUAL_CFLAGS) -Wp,-MD,$(@:.o.d=.tmp) -o $(dir $@)$(OBJECT_PREFIX)_$(notdir $(@:.o.d=.o)) $<
@sed -e '/^ *\\/d' -e "s#.*: #$@: #" $(@:.o.d=.tmp) > $@
@rm $(@:.o.d=.tmp)


So it can generate ".i" file for every ".c".

Thanks!

Thanks, but "-save-outputs" seems unrecognized when invoke arm-elf-gcc.
For example:
arm-elf-gcc -c -I/ecos-c/cygwin/opt/development/project/cpu_4c_lib/lib_install/include -I/opt/development/ecos/packages/language/c/libc/string/current -I/opt/development/ecos/packages/language/c/libc/string/current/src -I/opt/development/ecos/packages/language/c/libc/string/current/tests -I. -I/opt/development/ecos/packages/language/c/libc/string/current/src/ -finline-limit=7000 -mcpu=arm7tdmi -mno-short-load-words -Wall -Wpointer-arith -Winline -Wundef -Woverloaded-virtual -g -O0 -ffunction-sections -fdata-sections -fno-rtti -fno-exceptions -save-outputs -Wp,-MD,src/strcoll.tmp -o src/language_c_libc_string_strcoll.o /opt/development/ecos/packages/language/c/libc/string/current/src/strcoll.cxx


arm-elf-gcc: unrecognized option `-save-outputs'


I am using the prebuilt arm-elf-gcc from eCosCentric, the version is 3.2.1

Just add "-save-outputs" to your global GCC options.

Note: I normally do this by hand for the file(s) I'm interested in as
turning it on in a build tree will create tons of files, some of which
can be quite large...
