[ECOS] heap error

["Joerg Rapka" <joerg dot rapka at duagon dot com>]

Hi

I got the following error message, if I make the sample application
"hello.c".

$ make hello
m68k-elf-gcc -mcpu32 -msoft-float -c -o
hello.o -g -Wall -I/m/project/ecos/d103_
MvbApi/d103_install/include -ffunction-sections -fdata-sections hello.c
m68k-elf-gcc -mcpu32 -msoft-float -nostartfiles -L/m/project/ecos/d103_MvbAp
i/d1
03_install/lib -Wl,--gc-sections -o hello hello.o -Ttarget.ld -nostdlib
/m/project/ecos/d103_MvbApi/d103_install/lib/libtarget.a(services_memalloc_c
ommo
n_heaps.o): In function `global destructors keyed to
49900.cygmem_pool_heap1':
/m/Project/eCos/d103_MvbApi/d103_build/services/memalloc/common/current/heap
s.cx
x:19: undefined reference to `___heap1'
collect2: ld returned 1 exit status
make: *** [hello] Error 1

My configuration is as follows:
- Windows 2000 host
- m68k based target
- eCos configuration tools V1.3.1.2
- sources from CVS repository with tag "ecos-sw-2000-12-08"
- use template "elix"
- add memory region "heap1" to current configuration

I can solve the problem, if I modify the file "target.ld" located in the
"lib" directory of the install tree (in my case
"/m/project/ecos/d103_MvbApi/d103_install/lib").

Change line from
  __heap1   = ALIGN (0x2);
to
  ___heap1   = ALIGN (0x2);

What is going wrong there?

Thanks for help.
Best regards, Joerg
