Undefined reference even when linking to library (C++ evaluation version, Linux64)

[Wouter Spekkink]

Hi all,

I am having an issue with the evaluation version of Sparksee. I built a very basic program, just as a test, which is basically a small adaptation of the example used in the starting guide. I can't get the program to compile correctly. I have also tried to use the exact example of the starting guide, but I have the same problem there.

Even when linking to the correct shared library, I keep getting an "undefined reference" error whenever I call one of Sparksee's methods. The error looks like this:

make -k

/usr/lib/x86_64-linux-gnu/qt5/bin/qmake -o Makefile esDatabase.pro

g++ -m64 -Wl,-O1 -o esDatabase main.o   -L/usr/X11R6/lib64 -L/home/wouterspekkink/sparkseecpp-5.2.3/lib/linux64 -lsparksee -lQt5Widgets -lQt5Gui -lQt5Core -lGL -lpthread 

main.o: In function `main':

main.cpp:(.text.startup+0x124): undefined reference to `sparksee::gdb::Sparksee::Create(std::__cxx11::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> > const&, std::__cxx11::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> > const&)'

collect2: error: ld returned 1 exit status

Makefile:138: recipe for target 'esDatabase' failed

make: *** [esDatabase] Error 1

make: Target 'first' not remade because of errors.

Compilation exited abnormally with code 2 at Mon Oct 16 10:11:32

I've tried a bunch of things, like changing the order in which the libraries are linked, using the linux32 folder (this will just give me an error that I was trying to link to an incompatible library), and so on.

It almost seems like the methods were not actually implemented in the library, but perhaps I am doing something wrong (I am not exactly an expert coder). 

Does anyone have an idea what might be it?

Thanks in advance.

Hi,

It looks like you need the Sparksee version for C++11 linux 64.

Please, ask Dàmaris for the right version for you.

Hi,

Thanks for your quick response, and thanks for figuring out what causes the problem. After a bit of searching I just tried compiling the code with "#define _GLIBCXX_USE_CXX11_ABI" at the top of the source file, and it compiled with the evaluation version of the C++ code.

I will contact Dàmaris and ask about a C++11 version of Sparksee. 

Thanks again.

Best,

Wouter
