[ECOS] Building for freescale_twr_k60n512 failing under Cygwin

[ECOS] Building for freescale_twr_k60n512 failing under Cygwin

[Michael Bergandi]

I am attempting to exercise the eCos port to the Freescale
TWR-K60N512. However, I am currently unable to get it to even build
under Cygwin. I have followed the same procedure under Ubuntu 10.04
LTS and the build succeeds without issue. Unfortunately, for various
reasons, I need this to work on a Windows machine under Cygwin.

My current setup is:
Windows XP Pro SP3 32-bit
Latest cygwin (1.7.10) with tcl-tk bin and src v8.5
Current arm-eabi toolchain downloaded from an eCos mirror site
eCos from CVS (pulled down today: 2/12/2012)
ecosconfig binary from eCosCentric (I have also built my own, but same result)

The recipe I am using is:
mkdir ~/ecos-twr
cd ~/ecos-twr
cvs -z3 -d :pserver:anoncvs@ecos.sourceware.org:/cvs/ecos co -P ecos ecos-host
ECOS_REPOSITORY=~/ecos-twr/ecos/packages
export ECOS_REPOSITORY
mkdir ecosbuild
cd ecosbuild
ecosconfig new freescale_twr_k60n512 default
ecosconfig tree
make

The build eventually terminates with the following:

It looks to me like ecosconfig is not pulling over the source for the
memalloc service. Any ideas?

Thank you,

Check that you are able to invoke arm-eabi-gcc directly from a Cygwin
bash prompt to compile a trivial C file. Missing packages in a Cygwin
installation can sometimes lead to silent failure of the compiler.

I hope this helps...

I actually thought of this and double checked that the listed packages at:

http://ecos.sourceware.org/cygwin.html

were in fact installed. I have everything listed there at least in binary form.

I also invoked the following

$ arm-eabi-gcc.exe -c -o hello.o
-I../twrk60n512/ecosbuild/install/include hello.c

The hello.c is from the example directory and the include directory is
from building the ecos tree outside of cygwin.

I get no complaints from gcc and a hello.o is produced.

Any other ideas?

services/memalloc/common/current/cdl/memalloc.cdl:274

  make -priority 50 {
      heapgeninc.tcl : <PACKAGE>/src/heapgen.cpp
      $(CC) $(ACTUAL_CXXFLAGS) $(INCLUDE_PATH) -Wp,-MD,heapgen.tmp -E $< -o $@
      @sed -e '/^ *\\/d' -e "s#.*: #$@: #" heapgen.tmp > $(notdir $@).deps
      @rm heapgen.tmp
  }

Just a guess, may be that is `sed' issue? Try this make rule in a
terminal. Or  temporary remove silence sign '@' for sed in cdl.

Thanks Sergei. Sed was actually working fine.

I think there was a combination of problems. I think John was on the
right track about missing packages. Before I saw John's reply, I went
back and checked that I had all of the requisite packages. I saw that
I was actually missing patch and sharutils. Oddly, I have been
building the eCos 2 tree for years without them. However, I installed
patch and sharutils and the build still failed, which is why I
reported that I had all of them installed. What I failed to notice is
that the build failed in different way....  it couldn't find
arm-eabi-gcc.

Not finding gcc was a botch on my part. I used a relative path to my
tool chain. Now, it builds fine.
