Where is barebox-compressed set?
I tried it and it fails to link:
LD arch/arm/lib/built-in.o
LD barebox-uncompressed
SYSMAP System.map
OBJCOPY barebox-uncompressed.bin
LZO barebox-uncompressed.bin.lzo
CC piggy.lzo.o
LD barebox
common/built-in.o: In function `start_barebox':
.../barebox/common/startup.c:154: undefined reference to
`__barebox_initcalls_start'
.../barebox/common/startup.c:154: undefined reference to
`__barebox_initcalls_end'
$ make V=1
...
LD barebox
arm-linux-ld -EL -Map barebox.map -static --gc-sections -o barebox \
-T arch/arm/lib/barebox-compressed.lds \
--start-group common/built-in.o drivers/built-in.o
commands/built-in.o lib/built-in.o crypto/built-in.o net/built-in.o
fs/built-in.o arch/arm/boards/foo/built-in.o arch/arm/mach-foo/built-in.o
arch/arm/lib/built-in.o arch/arm/cpu/built-in.o piggy.lzo.o --end-group
It shouldn't link all the -built-in.o into the uncompressor, should it?
Or is it supposed to work via --gc-sections trick?
Thanks,
Johannes
