Audio / [Linux][SFML 2.4] Unexpected Linker Error

« on: August 30, 2016, 11:37:44 pm »

Hey guys,
I shall be brief.

• Installed SFML 2.1 via sudo apt-get install libsfml-dev
• updated via compiled SDK http://www.sfml-dev.org/download/sfml/2.4.0/

Makefile

CXXFLAGS = -std=c++11
LDLIBS = -lsfml-system -lsfml-window -lsfml-graphics -lsfml-audio -lsfml-network -lfftw3 -lm
OBJS = musicListener.o main.o


main: $(OBJS)
        g++ $(LDFLAGS) $^ $(LDLIBS) -o $@

%.o: %.cpp
        $(CXX) $(CPPFLAGS) $(CFLAGS) $(CXXFLAGS) -c -o $@ $<

$(OBJS): %.o: $(wildcard ./*.hpp) Makefile
 

This works like a charme:

 if (sf::SoundRecorder::isAvailable())
    {
        std::cout << SFML_VERSION_MAJOR << "." << SFML_VERSION_MINOR << std::endl;
        return 1;
    }
 

output :
2.4

Here i got the Linker Error:

auto devices = sf::SoundRecorder::getAvailableDevices();
 

Error:
main.o: In function `main':
main.cpp:(.text+0xf4): undefined reference to `sf::SoundRecorder::getAvailableDevices()'
collect2: error: ld returned 1 exit status

Well I can't find any issue about this in the git-repository or in the forum. Am I missing something ?

post scriptum : Also setDevice() does not work.

Regards,
Howell


EDIT : Well i wasn't able to figure it out, but linking to old .so makes sense. I made a Fresh LinuxOS install and it's working now. Thanks a lot !
I didn't wanted to reply, so this post will not push up
