libdwarf 安装使用

下载http://www.prevanders.net/dwarf.html

依赖http://directory.fsf.org/wiki/Libelf

dwarf格式文档http://www.dwarfstd.org/Home.php

直接./configure，make就好。

./configure
make

比较新的版本要替换 optind 和 opterr ，因为会和libc.a冲突

find . -name '*.[c|h]' -exec sed -i -e 's/optind/optind_kk/g' {} \;
find . -name '*.[c|h]' -exec sed -i -e 's/opterr/opterr_kk/g' {} \;

先动态编译，为了生成libdwarf/libdwarf.a

./configure
make
rm -rf dwarfdump/dwarfdump
make CFLAGS+="-static -I`pwd`/libdwarf -I`pwd`/dwarfdump" LDFLAGS+="-static -L`pwd`/libdwarf -ldwarf -lelf"
./dwarfdump/dwarfdump -Wc -S match=dev_queue_xmit /tmp/vmlinux

获取vmlinux中dev_queue_xmit函数的.debug信息
