Can't compile a simple c++ example

Rate this Message:
Hello,
I'm having trouble compiling a simple example of a c++ program for player/stage. I'm new in linux and I don't work so well with g++. When I compile like this: $ g++ -o ex1 -I/usr/include/player-2.0 ex1.cc I get this errors: /tmp/cc3YXRdN.o: In function `main': ex1.cc:(.text+0x107): undefined reference to `PlayerCc::PlayerClient::PlayerClient(std::basic_string<char, std::char_traits<char>, std::allocator<char> >, unsigned int, int)' ex1.cc:(.text+0x162): undefined reference to `PlayerCc::Position2dProxy::Position2dProxy(PlayerCc::PlayerClient*, unsigned int)' ex1.cc:(.text+0x177): undefined reference to `PlayerCc::PlayerClient::~PlayerClient()' ex1.cc:(.text+0x1bb): undefined reference to `PlayerCc::LaserProxy::LaserProxy(PlayerCc::PlayerClient*, unsigned int)' ex1.cc:(.text+0x1d2): undefined reference to `PlayerCc::Position2dProxy::SetMotorEnable(bool)' ex1.cc:(.text+0x1e1): undefined reference to `PlayerCc::Position2dProxy::RequestGeom()' ex1.cc:(.text+0x1ed): undefined reference to `PlayerCc::LaserProxy::RequestGeom()' ex1.cc:(.text+0x1fc): undefined reference to `PlayerCc::PlayerClient::Read()' ex1.cc:(.text+0x263): undefined reference to `PlayerCc::LaserProxy::~LaserProxy()' ex1.cc:(.text+0x27c): undefined reference to `PlayerCc::Position2dProxy::~Position2dProxy()' ex1.cc:(.text+0x295): undefined reference to `PlayerCc::PlayerClient::~PlayerClient()' /tmp/cc3YXRdN.o: In function `PlayerCc::Position2dProxy::SetSpeed(double, double)': ex1.cc:(.text._ZN8PlayerCc15Position2dProxy8SetSpeedEdd[PlayerCc::Position2dProxy::SetSpeed(double, double)]+0x39): undefined reference to `PlayerCc::Position2dProxy::SetSpeed(double, double, double)' collect2: ld returned 1 exit status Am I doing something wrong? The program is an example taked from a tutorial. Thanks, André Neves |

Try: g++ -o ex1 -I/usr/include/player-2.0 -lplayerc++ ex1.cc (Don't know if it's enough or other libs are missing too).

It's a lot easier to use pkg-config for dependancies. Try something like:
$ g++ -o ex1 `pkg-config --cflags --libs playerc++` ex1.cc
If you run the pkg-config command between the `` on its own, it'll output all of the include paths and libraries you'll need.

Hi, all
I feel painful when I first try to write a player client, so I wrote a generic Makefile (see the attachment) for a client a starter may find it useful. what you need to do is adjust the first few line of Makefile, which is the executable file name, lib path, include path. wish it help. best wishes Arik MakefileMakefile |
