Hello,everybody,in RedHat 9.0,i compiled u-boot v2010.12-rc3 with arm-linux-tools-20070808 On link stage,print some errors:

... ... ... ... -lgcc -Map u-boot.map -o u-boot net/libnet.o: In function `eth_halt': /home/code/uboot_v2010.12-rc3/net/eth.c:375: multiple definition of `eth_halt' drivers/net/libnet.o:/home/code/uboot_v2010.12-rc3/drivers/net/rtl8019.c:44: first defined here /usr/local/bin/arm-linux-ld.real: Warning: size of symbol `eth_halt' changed from 16 in drivers/net/libnet.o to 52 in net/libnet.o net/libnet.o: In function `eth_rx': /home/code/uboot_v2010.12-rc3/net/eth.c:393: multiple definition of `eth_rx' drivers/net/libnet.o:/home/code/uboot_v2010.12-rc3/drivers/net/rtl8019.c:44: first defined here /usr/local/bin/arm-linux-ld.real: Warning: size of symbol `eth_rx' changed from 132 in drivers/net/libnet.o to 48 in net/libnet.o net/libnet.o: In function `eth_init': /home/code/uboot_v2010.12-rc3/net/eth.c:335: multiple definition of `eth_init' drivers/net/libnet.o:/home/code/uboot_v2010.12-rc3/drivers/net/rtl8019.c:93: first defined here /usr/local/bin/arm-linux-ld.real: Warning: size of symbol `eth_init' changed from 236 in drivers/net/libnet.o to 208 in net/libnet.o net/libnet.o: In function `eth_send': /home/code/uboot_v2010.12-rc3/net/eth.c:385: multiple definition of `eth_send' drivers/net/libnet.o:/home/code/uboot_v2010.12-rc3/drivers/net/rtl8019.c:235: first defined here /usr/local/bin/arm-linux-ld.real: Warning: size of symbol `eth_send' changed from 192 in drivers/net/libnet.o to 56 in net/libnet.o /usr/local/bin/arm-linux-ld.real: u-boot: warning: allocated section `.bss' not in segment common/libcommon.o:(.data+0x764): undefined reference to `environment' make: *** [u-boot] Error 139

These words show me that net/eth.c has "eth_send" and drivers/net/rtl8019.c also has "eth_send" function as the same name. My board use RTL8019AS ethernet controller,s3c44b0 CPU. i couldn`t figure out what is wrong with the code and how to fix it,Thanks a lot for any suggestion MrGates
