I have been trying to make an Eclipse/CDT (Juno) project for eCos, but not a
Makefile project. Mainly so that it can navigate to h files, and try to see if
it will drive GDB.
Eclipse seems to ignore linker options and do its own thing. For example, for
the linker I have:
-mcpu=cortex-m3 -mthumb -Wl,--gc-sections -Wl,-static -Wl,-n -g -v -nostdlib
-T../../ecos/TWR-K60D100M_install/lib/target.ld
But, it appears that some options, like -T are ignored. And the linker tries to
link in crt0.o, even if I set the compile options to not include startup files.
What is surprising is Eclipse make a makefile that seemed correct. Although, I
am not a gcc/make expert. I did notice it puts all the options on one line,
rather than splitting the build into compile and link. Perhaps that is part of
the problem. See the makefile below.
Is there a way to make Eclipse strictly obey all my options and build properly?
Does anyone have a simple project I can look at to see how to set this up?
Is this a complete waste of my time?
Mike
