RE: [ECOS] Having trouble building

[Gary Parnes]

Actually I tried "ecosconfig new innovator redboot" first, and that resulted
in the same error.

I was wondering why rules.mak isn't removing "-Woverloaded-virtual" and
whatnot. That it hit me.... the rules.mak file only handles general
compilation. The problem appears to be in the CDL files that generate very
specific compilation rules.  They're generating specialized rules that
contain $(CFLAGS) instead of $(ACTUAL_CFLAGS), bypassing the ACTUAL_CFLAGS
constructs in rules.mak.

So, which would be the proper solution:  modifying rules.mak to set CFLAGS
equal to ACTUAL_CFLAGS after the flags have been scrubbed, or modify the CDL
files to use ACTUAL_CFLAGS when creating specialized rules?

The latter, definitely.  In fact, I would think that all such CDL/rules
should be changed similarly.

Let us know how this works out for you.

Those flags are mentioned directly in the innovator CDL - they probably
should not be.

Also note: the comment in 'ecos.db' says that this platform is not fully
eCos-ready, only RedBoot is supported, so I'm not sure what success you
will have overall.  (n.b. I've not tried this platform at all, so the
comments may be out of date w.r.t. the actual port)

[ECOS] Having trouble building

[Gary Parnes]

I'm trying to build eCos for the Innovator platform using a fresh checkout
(using arm-elf-gcc version 3.2), and I'm not getting very far.

Using the precompiled ecosconfig binary from the standard distribution:

$ ecosconfig new innovator default
$ ecosconfig tree
$ make

And lo and behold...

make -r -C hal/arm/arch/current arm.inc
make[1]: Entering directory `/home/garyp/ev/hal/arm/arch/current'
arm-elf-gcc -finline-limit=7000 -mcpu=arm9 -Wall -Wpointer-arith
-Wstrict-protot
ypes -Winline -Wundef -Woverloaded-virtual -g -O2 -ffunction-sections
-fdata-sec
tions -fno-rtti -fno-exceptions

hal_mk_defs.tmp

.
c
cc1: unrecognized option `-Woverloaded-virtual'
cc1: unrecognized option `-fno-rtti'
make[1]: *** [arm.inc] Error 1
make[1]: Leaving directory `/home/garyp/ev/hal/arm/arch/current'
make: *** [build] Error 2


What's going on here?  I thought rules.mak got rid of -Woverloaded-virtual
and such when compiling straight C code.

This is using Cygwin as the build platform.
