1.download buildroot,gcc,bintuils.uclibc linux-header

2.upack buildroot

3.mkdir /buildroot/dl

4.put uclibc ,gcc,bintuils tarball in dl

5.cd buildroot make menuconfig

failed

fixed as follow

10. test build

hello in c

hello in c++

hello with pthread

build with shared libc, and -static

you will find some error at "***.os"

cd uClibc-xxx; rm the "**.os" then make; and cp -a lib/* to toolchain lib

 

11.test again

failed at link hello-thread static

in uClibc-*/libpthread/linuxthreads/Makefile.in, i add a libc-cancellation.o

i am not sure it correct, but it workes

libc-static-y += $(libpthread_OUT)/libc_pthread_init.o $(libpthread_OUT)/libc-cancellation.o

 

12.OK
