gcc - C++ compile issue - 


meme@ubuntu:~/data$ g++ udpechoserver.cpp practicalsocket.cpp -o udpskserv -lsocket -lnsl -mt

i trying compile @ compiler ubuntu , receive error

cc1plus: error: unrecognized command line option ‘-mt’

may ask -mt , try google can't find information.

if try omit -mt parameter error

practicalsocket.cpp: in constructor ‘socketexception::socketexception(const string&, bool)’: practicalsocket.cpp:33:38: error: ‘strerror’ not declared in scope practicalsocket.cpp: in function ‘void filladdr(const string&, short unsigned int, sockaddr_in&)’: practicalsocket.cpp:47:32: error: ‘memset’ not declared in scope practicalsocket.cpp: in member function ‘void socket::setlocalport(short unsigned int)’: practicalsocket.cpp:119:42: error: ‘memset’ not declared in scope practicalsocket.cpp: in static member function ‘static short unsigned int socket::resolveservice(const string&, const string&)’: practicalsocket.cpp:153:32: error: ‘atoi’ not declared in scope practicalsocket.cpp: in member function ‘void udpsocket::disconnect()’: practicalsocket.cpp:291:40: error: ‘memset’ not declared in scope

both std::memset , std::strerror declared in <cstring> header, need #include one.

and gcc not have -mt option.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
