[ECOS] no memory reason specified for loadable section ".bss.getc_info"

[Harish Kulkarni]

Hello,

We are building eCos redboot with gcc 3.4.4 for leon
and finding the following compilation issue.

We can compile the same peice of code with gcc 3.2.1.

sparc-elf-gcc -msoft-float -g -nostdlib
-Wl,--gc-sections -Wl,-static -L/ecos-c/
cygwin/tmp/leon_cyc_sparcelf/install/lib -Ttarget.ld
-o /ecos-c/cygwin/tmp/leon_
cyc_sparcelf/install/bin/redboot.elf
/ecos-c/cygwin/tmp/leon_cyc_sparcelf/instal
l/lib/version.o
/compilers/sparc-elf/lib/gcc/sparc-elf/3.4.4/../../../../sparc-elf/bin/ld:
error
: no memory region specified for loadable section
`.bss.getc_info'
collect2: ld returned 1 exit status
make[1]: ***
[/ecos-c/cygwin/tmp/leon_cyc_sparcelf/install/bin/redboot.elf]
Error 1

-Thanks
Harish

This is probably a linker script issue. I saw it on another architecture
recently. Try something like this:

*** sparc.ld.~1.3.~	Thu Apr 10 14:07:58 2003
--- sparc.ld	Fri Aug 12 08:12:50 2005
***************
*** 125,131 ****
  #define SECTION_bss(_region_, _vma_, _lma_) \
      .bss _vma_ : _lma_ \
      { __bss_start = ABSOLUTE (.); \
!     *(.scommon) *(.dynbss) *(.bss) *(COMMON) \
      __bss_end = ABSOLUTE (.); } \
      > _region_
  
--- 125,131 ----
  #define SECTION_bss(_region_, _vma_, _lma_) \
      .bss _vma_ : _lma_ \
      { __bss_start = ABSOLUTE (.); \
!     *(.scommon) *(.dynbss) *(.bss*) *(COMMON) \
      __bss_end = ABSOLUTE (.); } \
      > _region_
