gdb调试c语言在poll函数卡住,交叉编译gdb，调试时出现几个搞不明白的问题

我使用的Ubuntu系统

#uname -r

2.6.32-21-generic

#lsb_release -a

No LSB modules are available.

Distributor ID: Ubuntu

Description: Ubuntu 10.04 LTS

Release: 10.04

Codename: lucid

1.下载gdb7.5

2.下载ncurses-5.8 (gdb7.5依赖ncurses，所以需要先编译ncurses)

3.编译ncurses 然后把生成库文件和头文件拷贝到 arm-vfp_uclibc-linux-gnu-gcc 相应的库目录和头文件目录

(1)先配置编译选项

./configure --prefix=/mnt/nfs/tmp/ncurses-5.8/out \

--host=arm-vfp_uclibc-linux-gnu \

CC=/opt/hisi-linux/x86-arm/gcc-3.4.3-csl-uClibc-0.9.30-softvfp/bin/arm-vfp_uclibc-linux-gnu-gcc

(2)make

(3)cp

4.编译gdb7.5

(1)先配置编译选项

../gdb-7.5/configure \

--host=arm-vfp_uclibc-linux-gnu \

--target=arm-vfp_uclibc-linux-gnu \

CC=/opt/hisi-linux/x86-arm/gcc-3.4.3-csl-uClibc-0.9.30-softvfp/bin/arm-vfp_uclibc-linux-gnu-gcc \

--without-x --disable-gdbtk --disable-tui --without-included-gettext --without-included-regex --enable-static \

--program-prefix=arm-hi3110-v200- \

--prefix=/mnt/nfs/tmp/gdb-7.5/out

(2)make&&make install

(3)arm-vfp_uclibc-linux-gnu-strip arm-hi3110-v200-gdb

5.使用gdb调试

# ./arm-hi3110-v200-gdb myapp
