GDB安装问题

Question

toolchain version:
gcc-3.3.2
glibc-2.2.5
binutils-2.15
目录:
drwxr-xr-x 7 root root 4096 03-15 16:47 arm-gdb
lrwxrwxrwx 1 root root 12 03-09 10:59 armv5l -> armv5l-2.6.x
drwxr-xr-x 3 root root 4096 03-15 15:40 armv5l-2.6.x

安装步骤:
下载解压gdb-6.6
#cd gdb-6.6
#./configure --target=arm-linux --prefix=/usr/local/arm-gdb -v
#make ＆ make install
OK，然后:
#export PATH=$PATH:/usr/local/arm-gdb
进入gdbserver目录：
#./configure --target=arm-linux �host=arm-linux
#make CC=/usr/local/armv5l/3.3.2/bin/armv5l-linux-gcc
出错:
/usr/local/armv5l/3.3.2/bin/armv5l-linux-gcc -c -Wall -g -O2 -I. -I. -I./../regformats -I./../../include -I../../bfd -I./../../bfd linux-arm-low.c
linux-arm-low.c:35:21: sys/reg.h: 没有那个文件或目录
make: *** [linux-arm-low.o] 错误 1

然后把/usr/include/sys/reg.h copy到/usr/local/armv5l-2.6.x/3.3.2/armv5l-linux/include/sys/reg.h
再make,显示错误:
/usr/local/armv5l/3.3.2/bin/armv5l-linux-gcc -c -Wall -g -O2 -I. -I. -I./../regformats -I./../../include -I../../bfd -I./../../bfd thread-db.c
thread-db.c: In function `thread_db_err_str':
thread-db.c:95: error: `TD_VERSION' undeclared (first use in this function)
thread-db.c:95: error: (Each undeclared identifier is reported only once
thread-db.c:95: error: for each function it appears in.)
thread-db.c: In function `thread_db_get_tls_address':
thread-db.c:336: warning: implicit declaration of function `td_thr_tls_get_addr'
thread-db.c:336: warning: cast to pointer from integer of different size
thread-db.c:340: warning: cast from pointer to integer of different size
make: *** [thread-db.o] 错误 1

本想继续fix error，但是感觉不太对，请问各位，是什么原因呢？
是不是CC的target写错了？应该是arm-linux还是armv5l-linux?
谢谢了～

从后面的错误信息来看，应该是你的交叉编译工具链不支持nptl线程库。
