address 0xcaa58 of test section .bss is not within region ram

Hello,

I am a newbie developing a httpd application on eCos plaform. I got
the following error while compiling a httpd application using arm-elf:

[root@localhost httpd_application]# make

What is the reason for getting the error of "section .bss is not
within region ram" for this case?

How can I remedy this problem? (Are there some variables which I need
to change to define the ram region?)

Thanks in advance!

Time to look at your map file and see where things are being allocated.
Then create your own custom linker control file (modify the default one
being used now) and change the 'ram' region size to match your system. Or
you may simply be out of memory and the .bss section has overflowed
available ram.

This means that your header file is not compliant to the standard.

This means that the function is not declared to the compiler in a
heaader, maybe a mis-print in the call.

The pointer in second argument of cyg_thread_create() is wrong.

Show the contents of the file target.ld. Check that the memory ranges
in the loader script matches your hardware. If it is correct, your
program + data is too large.

The section .bss in C runtime code contains the unintialized static
data of the program.

You are making another newbie mistake by trying to fix the error message and
ignoring the tons of warning messages you're getting. Newbies think "well, it's
just a warnng, not a real error" but such things can create very hard to find
bugs later on and some of those warnings might actually be causing the error(s)
you get.

Been there. Done that.  :-/
