编译遇到的问题
- 按照官网步骤设置PKG_CONFIG_PATH后，执行make报错如下
root@ubuntu:~/dpvs# export PKG_CONFIG_PATH=/root/dpvs/dpdk/dpdklib/lib/x86_64-linux-gnu/pkgconfig/libdpdk.pc
root@ubuntu:~/dpvs# make
for i in src tools; do make -C $i || exit 1; done
make[1]: Entering directory '/root/dpvs/src'
/root/dpvs/src//dpdk.mk:47: *** DPDK library was not found.
If dpdk has installed already, please ensure the libdpdk.pc file could be found by `pkg-config`.
You may fix the problem by setting LIBDPDKPC_PATH (in file src/dpdk.mk) to the path of libdpdk.pc file explicitly. Stop.
make[1]: Leaving directory '/root/dpvs/src'
make: *** [Makefile:33: all] Error 1
修改：PKG_CONFIG_PATH应该是*.pc所在目录，如下设置即可。
export PKG_CONFIG_PATH=/root/dpvs/dpdk/dpdklib/lib/x86_64-linux-gnu/pkgconfig
- 没有numa头文件
/root/dpvs/src/common.c:24:10: fatal error: numa.h: No such file or directory
24 | #include <numa.h>
修改：安装libnuma-dev即可。apt install libnuma-dev

- 编译keepalived时报错如下
check_data.c: In function ‘dump_forwarding_method’:
check_data.c:368:33: error: ‘IP_VS_CONN_F_TUNNEL_TYPE_IPIP’ undeclared (first use in this function); did you mean ‘IP_VS_CONN_F_TUNNEL’?

修改：注释掉下面两行

#$as_echo "#define _HAVE_IPVS_TUN_TYPE_ 1 " >>confdefs.h
# SYSTEM_OPTIONS="$SYSTEM_OPTIONS IPVS_TUN_TYPE"

- 缺少依赖库
ipvsadm.c:114:10: fatal error: popt.h: No such file or directory

修改：安装 apt-get install libpopt-dev

修改：修改dpip的makefile，添加CFLAGS += $(DEFS) -Wno-address-of-packed-member
