Hello! I am trying to build a server on Linux and I'm having issues. Everything links properly except some network functions. Here is my minimal example:
#include <SFML/Network.hpp>
int main() {
sf::Http http("http://127.0.0.1", 8080);
}
The code compiles with no issues. When I use GCC to build it without linking, it gives the following output:
g++ main.o -o out
main.o: In function `main':
main.cpp:(.text+0x3e): undefined reference to `sf::Http::Http(std::string const&, unsigned short)'
main.o:(.rodata._ZTIN2sf9TcpSocketE[_ZTIN2sf9TcpSocketE]+0x10): undefined reference to `typeinfo for sf::Socket'
main.o: In function `sf::TcpSocket::~TcpSocket()':
main.cpp:(.text._ZN2sf9TcpSocketD2Ev[_ZN2sf9TcpSocketD5Ev]+0x30): undefined reference to `sf::Socket::~Socket()'
collect2: error: ld returned 1 exit status
You might think "well you must link against sfml-network." When I do that, it gives me the following:
g++ main.o -o out -lsfml-network -lsfml-system
main.o: In function `main':
main.cpp:(.text+0x3e): undefined reference to `sf::Http::Http(std::string const&, unsigned short)'
collect2: error: ld returned 1 exit status
As you can see, linking against network gives me less linker errors but still one. I have verified that the .so libraries exist in a place that g++ can find, so this makes me believe something might be wrong with the shared object. The same code runs with VC++ just fine.
The odd part is that I can compile and link the following code with no issues:
#include <SFML/Network.hpp>
int main() {
sf::Packet pack;
pack.clear();
}
That leaves me completely stumped as to why I can't link against sfml-network specifically for Http. If you have any ideas or request more info, let me know! Thank you for your help.
