g++ -Wall -g3 -c kcp_client.cpp -o kcp_client.o
kcp_client.cpp: In member function ‘void asio_kcp::kcp_client::do_send_connect_packet(uint64_t)’:
kcp_client.cpp:149:108: error: ‘strerror’ was not declared in this scope
std::cerr << "do_asio_kcp_connect send error return with errno: " << errno << " " << strerror(errno) << std::endl;
头文件<string.h> 在.cpp里已经包含，有谁遇见过吗？
I guess the problem is the version of gcc.
Which version on your computer?
Please try using gcc 4.8 or newest gcc.
And please tell the result.
gcc version is 5.2, i'm sure
[root@192 client_lib]# g++ -v
Using built-in specs.

Summary : The GNU libc libraries
Description :
The glibc package contains standard libraries which are used by
multiple programs on the system. In order to save disk space and
memory, as well as to make upgrading easier, common system code is
kept in one place and shared between programs. This particular package
contains the most important sets of shared libraries: the standard C
library and the standard math library. Without these two libraries, a
Linux system will not function.

I can't help you. I have no idea.
Please write down the method if you solved it.
And this will help me and others.
Thx anyway! i'll try my best
i changed “strings.h ” to “ cstring” in files "kcp_client.cpp" , "kcp_client_util.cpp"; and added the head file “stdio.h” to file util/ikcp.c. thus, all clear!
