glibc compile

get three packages from http://ftp.gnu.org/gnu/glibc/.

glibc-2.12.1.tar.bz2

glibc-linuxthreads-2.5.tar.bz2()

glibc-ports-2.9.tar.bz2

 

1. CC=arm-none-linux-gnueabi-gcc CFLAGS="-mfloat-abi=softfp -O2" /home/ben/Works/Software/glibc-2.12.1/configure --build=i686-linux --host=arm-linux --prefix=/home/ben/Works/Tools/glibc6-armlibls --enable-add-ons=nptl,/home/ben/Works/Software/glibc-ports-2.9/

2. make

3. make install

 

when get error like:

configure: error: gcc must provide the <cpuid.h> header

workaround:

get the cpuid.h file from official GCC respositories > (http://gcc.gnu.org/viewcvs/tags/gcc_4_4_2_release/gcc/config/i386/cpuid.h?view=co ) > and put it into arm-2007q3-csr-build/arm-none-linux-gnueabi/libc/usr/include. > glibc should compile without problem now.

"glibc cannot be compiled without optimization"

solution: specific CFLAGS when configure glibc with -O2, (refer to http://www.cygwin.com/ml/libc-alpha/2007-09/msg00032.html)



[3]
error: #error "TLS support is required."

solution:remove definition in glibc-ports-2.9/sysdeps/arm/nptl/tls.h



No idea for this phenomenon, use codesourcery compile scripts.
