[ELDK] help: i got a core dumped while building u-boot-2011.06 use eldk5.0 for armv4t.

[liujun]

hi, all

i got a core dumped while building u-boot-2011.06 for s3c2440a chip 

which is arch v4t use eldk5.0 with USE_PRIVATE_LIBGCC=yes.

building is ok without USE_PRIVATE_LIBGCC=yes but only got a v5t 

elf u-boot file.

 

my building is on centos 6.0, all env variable setting is done as following:

 

export PREFIX=/opt/eldk-5.0/armv5te/sysroots/i686-oesdk-linux/usr/bin

export TARGET=arm-linux-gnueabi

export PATH=$PREFIX/armv5te-linux-gnueabi:$PATH

export CROSS_COMPILE=${TARGET}-

 

building command is following by denx faq ¡°GCC generates illegal opcodes
for ARMv4T systems¡±

make distclean

USE_PRIVATE_LIBGCC=yes make AS2440_config

USE_PRIVATE_LIBGCC=yes make

 

                            here is my building error message:

#---------------------------------------------------------------------------

                            i made u-boot without USE_PRIVATE_LIBGCC again
before click send button for this mail, everything

                            is ok, no error message, and check again

 

                            ${CROSS_COMPILE}readelf -a u-boot > u-boot.txt

 

                            at end of u-boot.txt, there are¡­

I think, ¡°USE_PRIVATE_LIBGCC=yes¡± get the __aeabi_uldivmod off libgcc, but
u-boot source maybe still

call it, I¡¯m not sure.

 

ps

just see it stdout message when making, it¡¯s printed out by making without
USE_PRIVATE_LIBGCC :

gcc compiling seem like using arch v4.

 

then, I make with USE_PRIVATE_LIBGCC=yes again, I got a core dumped again.
