Hi all, I'm having a linking problem with GCC and iostream. I'm not sure if it has anything to do with cygwin, so I'll check here.
I am using #include <iostream> using namespace std; Its a pretty large project. First, all the sources and compiled into object files using gcc. Then to link, I've tried both gcc and g++. Both times using -lstdc++ as a paramter. Yet, I always seem to get iostream errors like: : undefined reference to `ostream::operator<<(char const*) : undefined reference to `_cin' : undefined reference to `_cout' :undefined reference to `istream& operator>><int>(istream&, smanip<int> const&)' Below is the output of gcc/g++ -print-search-dirs ************************************************** install: /usr/lib/gcc-lib/i686-pc-cygwin/3.3.1/ programs: =/usr/lib/gcc-lib/i686-pc-cygwin/3.3.1/:/usr/lib/gcc-lib/i686-pc-cygwin/3.3.1/:/usr/lib/gc c-lib/i686-pc-cygwin/:/usr/lib/gcc/i686-pc-cygwin/3.3.1/:/usr/lib/gcc/i686-pc-cygwin/:/usr/lib/gcc-l ib/i686-pc-cygwin/3.3.1/../../../../i686-pc-cygwin/bin/i686-pc-cygwin/3.3.1/:/usr/lib/gcc-lib/i686-p c-cygwin/3.3.1/../../../../i686-pc-cygwin/bin/ libraries: =/usr/lib/gcc-lib/i686-pc-cygwin/3.3.1/:/usr/lib/gcc/i686-pc-cygwin/3.3.1/:/usr/lib/gcc-l ib/i686-pc-cygwin/3.3.1/../../../../i686-pc-cygwin/lib/i686-pc-cygwin/3.3.1/:/usr/lib/gcc-lib/i686-p c-cygwin/3.3.1/../../../../i686-pc-cygwin/lib/:/usr/lib/gcc-lib/i686-pc-cygwin/3.3.1/../../../i686-p c-cygwin/3.3.1/:/usr/lib/gcc-lib/i686-pc-cygwin/3.3.1/../../../:/lib/i686-pc-cygwin/3.3.1/:/lib/:/us r/lib/i686-pc-cygwin/3.3.1/:/usr/lib/ ************************************************ My compile line is: gcc/g++ -mno-cygwin -g -o$(_Target) -LC:\cygwin\lib\mingw -Wl,--start-group -lwsock32 -lstdc++ <files needed to be linked> -Wl,--end-group I doubt this is a code problem, though its always possible. I think its some setup option or something like that. any ideas?
