Many Thanks Andrew. I have finally sorted it out although i think my eyes are giving up on my after careful comparing lots of files. It turns out that line 2 of my custom build step had the -S missing from it so gcc was trying to assemble and link the file rather than just compile it.
Many thanks, no I can proceed.

The "-priority 1" controls when this section of make script is
executed. See:
http://ecos.sourceware.org/ecos/docs-latest/cdl-guide/build.make.html#BUILD.CUSTOM
One guess as to why it does not do it is because the dependencies are
wrong somehow. It thinks the target is up to date so there is no need
to rebuilt it. Deleting the file should force it to rebuild it.

I have a working V2 source tree of eCos with which I can build a library for an SH2. I also have the latest source tree with which I get a build problem.
During the start of the build process, 2 files, hal_mk_defs.c and var_mk_defs.c are processed. The source file is compiled to a tmp file and an 'fgrep' command is then run on it outputted to a file sh_offsets.inc, this is then compiled.
On my working tree both these files go through this fgrep process. On my non-working but up-to-date tree, only the first file has fgrep run on it and so the second one fails to build:
Working build:

The fgrep command is specified in the architecture cdl script:
make -priority 1 {
<PREFIX>/include/cyg/hal/sh2_offsets.inc : <PACKAGE>/src/var_mk_defs.c
$(CC) $(CFLAGS) $(INCLUDE_PATH) -Wp,-MD,sh2_offsets.tmp -o var_mk_defs.tmp -S $<
fgrep .equ var_mk_defs.tmp | sed s/#// > $@
@echo $@ ": \\" > $(notdir $@).deps
@tail +2 sh2_offsets.tmp >> $(notdir $@).deps
@echo >> $(notdir $@).deps
@rm sh2_offsets.tmp var_mk_defs.tmp
}
The scripts in both the working and non-working trees are identical. Can anyone tell me where this fgrep command is called from in the build process or why in one build this doesn't happen the second time.
I am really scratching my head as I can't use the latest source until I sort out this problem.
Many Thanks in advance.
