[ECOS] Using RedBoot_cmd

[ECOS] Using RedBoot_cmd

[Guillaume Menant]

Hi,

I'm trying to add a command to RedBoot with inserting the following code in
a file names pci.c placed in the src of redboot package:

-----------------------------------------
#include <redboot.h>

void
do_pcitest(int argc, char *argv[]);

RedBoot_cmd("pcitest", 
            "Tests PCI block",
            "",
            do_pcitest
    );

void
do_pcitest(int argc, char *argv[])
{
}
-----------------------------------------

But I'm facing to this when I'm trying to compile:

-----------------------------------------
sparc-rtems-gcc -msoft-float -g -nostdlib -Wl,--gc-sections -Wl,-static
-L/ecos-f/TEMP/untitled_install/lib -Ttarget.ld -o
/ecos-f/TEMP/untitled_install/bin/redboot.elf
/ecos-f/TEMP/untitled_install/lib/version.o
make[1]: Leaving directory `/ecos-f/TEMP/untitled_build/redboot/v2_0'
/ecos-f/TEMP/untitled_install/lib/extras.o(.ecos.table.RedBoot_commands.data
.do_pcitest+0xc): undefined reference to `do_pcitest'
make: Leaving directory `/ecos-f/TEMP/untitled_build'
collect2: ld returned 1 exit status
make[1]: *** [/ecos-f/TEMP/untitled_install/bin/redboot.elf] Error 1
make: *** [build] Error 2
-----------------------------------------

Why my do_pcitest function is undefined?

Thanks for your time.

Use nm to see if the symbol really is in the object file and in the
library.  Also check it has not been C++ name mangled.

Leave out the declaration of the function - the RedBoot_cmd()
macro will declare it as static.  I think this is what's causing
the confusion.

Thanks for your answers; it was due to a #ifdef I haven't seen before :-(
