problem on building cross gcc: _G_config.h

["朱鹏飞" <zhupf at cgdp dot nju dot edu dot cn>]

I am compliling cross tool chain for ARM7TDMI, I choose binutils-2.10.1, gcc-2.95.3 and uClibc-0.9.26, the Linux kernel I use is Linux-2.4.20 and I patched with uClinux patch for this kernel. 
My steps are as following: 
                    
1. set up workspace 
1.1 create subdirectory in /home/zpf/haimai: 
$ mkdir bootldr build-tools debug doc images kernel project rootfs sysapps tmp tools 
bootldr: The bootloader or bootloaders for the target 
build-tools The packages and directories needed to build the cross-platform development toolchain 
debug: The debugging tools and all related packages 
doc: All the documentation need for the project 
images: The binary images of the bootloader, the kernel, and the root filesystem ready to be used on the target 
kernel: The different kernel versions for the target 
project: My own source code for this project 
rootfs: The root filesystem as seen by the target's kernel at runtime 
sysapps: The system applications required for the target 
tmp: A temporary directory to experiment and store transient files 
tools: The complete cross-platform development toolchain and C library 
all packages downloaded are put in build-tools directory. 
1.2 Write a shellscript haimai.sh to export environment variables: 
export PROJECT=haimai 
export PRJROOT=/home/zpf/${PROJECT} 
export TARGET=arm-linux 
export PREFIX=${PRJROOT}/tools 
export TARGET_PREFIX=${PREFIX}/${TARGET} 
export PATH=${PREFIX}/bin:${PATH} 
cd $PRJROOT 


2. kernel headers set up 
download Linux kernel 2.4.20 from: 
http://www.kernel.org/pub/linux/kernel/v2.4/ 

download kernel patch for uClinux from: 
http://www.uClinux.org/pub/uClinux/uClinux-2.0.x/ 
unpack the kernel and patch to ${PRJROOT}/kernel, patch the kernel: 
$ patch -p1 < uClinux-2.4.20-uc1.diff 
then begin to configure the kernel, run make menuconfig: 
$ make ARCH=armnommu CROSS_COMPILE=arm-linux- menuconfig 
$ make dep 
only select the CPU type during this step. 

after this, copy the kernel head to ${TARGET_PREFIX} 
$ mkdir -p ${TARGET_PREFIX}/include 
$ cp -r include/linux/ ${TARGET_PREFIX}/include 
$ cp -r include/asm-armnommu/ ${TARGET_PREFIX}/include/asm 
$ cp -r include/asm-generic/ ${TARGET_PREFIX}/include 


3. build binutils 
$ ../binutils-2.10.1/configure --target=$TARGET --prefix=${PREFIX} 
$ make 
$ make install 
after this step, binutils can be seen in ${PREFIX}/bin: 
$ ls ${PREFIX}/bin 
arm-linux-addr2line arm-linux-ld arm-linux-readelf 
arm-linux-ar arm-linux-nm arm-linux-size 
arm-linux-as arm-linux-objcopy arm-linux-strings 
arm-linux-c++filt arm-linux-objdump arm-linux-strip 
arm-linux-gasp arm-linux-ranlib 
A copy of some of the utilities without the prepended target name is also installed in the ${PREFIX}/${TARGET}/bin directory. 


4. build bootstrap gcc 
$ ../gcc-2.95.3/configure --target=$TARGET --prefix=${PREFIX} --without-headers --with-newlib --enable-languages=c 

this step seemed to have missed to copy some files to ${PREFIX}/${TARGET}/sys-include 
so the next step go wrong: 
$ make all ?gcc 
error: something about pthread.h 
To solve this problem, Edit gcc/config/arm/t-linux 
and add 
-Dinhibit_libc and -D__gthr_posix_h 
to: 
TARGET_LIBGCC2_CFLAGS. 

After edition of the file ,run configure with disable-threads option: 
$ ../gcc-2.95.3/configure --target=$TARGET --prefix=${PREFIX} --without-headers --with-newlib --enable-languages=c --disable-threads 
then run: 
$ make all-gcc 
no error message this time. 

With the compilation complete, install gcc: 
$ make install-gcc 
Check ${PREFIX}/bin, we can find arm-linux-gcc is there. 


5. build uClibc 
$ make CROSS=i386-linux- menuconfig 
In Target Architecture option, I select arm; 
In Target Architecture Features and Options: 
In Target Process Type, I choose generic arm; 
Disable MMU and Float Point Number Support; 
The Linux kernel header location is set to ${PRJROOT}/kernel/linux-2.4.20; 
In Library Installation Options: 
shared library loader path is set to /lib 
uClibc runtime library directory is set to /home/zhupf/haimai/tools/RTLib 
uClibc development environment directory (DEVEL_PREFIX) is set to ${PRJROOT}/tools/DevEnv 

after menuconfig, then: 
$ make CROSS=arm-linux- 
$ make CROSS=arm-linux- PREFIX="" install 


6. build complete gcc 
first edit the file gcc/config/arm/t-linux 
$ cd ${PRJROOT}/build-tools/build-gcc 
$ ../gcc-2.95.3/configure --target=$TARGET --prefix=${PREFIX} --enable-languages=c,c++ 
$ make all 

In step6, some error message appear (I append the result of make all below), so could anybody tell me what is wrong? and what should I do? 

Thanks in advance!
