I downloaded krakatoa SR to my linumx box. I figure the code to build the example would be something like:
gcc -v -Wall -std=c++11 -Iinclude -L lib-linux-x64 -lKrakatoaSR -ltbbmalloc -ltbb examples/example02.cpp But i get errors such as:
example02.cpp:(.text+0x20): undefined reference to `krakatoasr::krakatoa_renderer::krakatoa_renderer()'Am i missing something here?
Hi spirail,
Would it be possible to get the full build output log as well as the version of gcc and the OS you’re using?
Also, do these errors occur when you try to build any of the examples, or just 2?
Occurs on all of the examples.
I just used example02 as krakatoa_renderer is the first error in this example.
I would really like to be sure the build command is correct
This is the Krakatoa version i downloaded from the official site:

/tmp/cchRdnc8.o:(.eh_frame+0x13): undefined reference to `__gxx_personality_v0'Thanks for the information. I’ll look into this and let you know when I have a solution.
Is “include” in the current working directory? I usually see those errors when gcc can’t find my headers. I haven’t played with the Krakatoa library yet, but you can also try providing the full path in the “-I” path (capital i)
Just crazy ideas while we wait for Evan.
yes. it is. … if it wasn’t the error would be that it cannot find the header file which is in the first line of every example.
The declarations are being found. But it’s the functions themselves that are not being found - i guess.
Its not the -L command either. I have tried to copy the libs to the main c paths also.
The -l (lower cause L) seem to find the .so files correctly (since gcc does not error). So it seems to be that its not finding the functions in the .so file.
… im wondering if this is not compiled against the correct architecture for me. ie: intel/amd/32/64 etc etc.
The arguments are just in the wrong order. The following should build.
g++ -v -Iinclude -Llib-linux-x64 examples/example02.cpp -lKrakatoaSR -ltbbmalloc -ltbb
