These instructions show how to setup a basic C++ project which uses the
VLFeat library and the g++ compiler. Our project will consist
of the following simple file, which we will refer to
as main.cpp:
extern "C" {
#include <vl/generic.h>
}
int main (int argc, const char * argv[]) {
VL_PRINT ("Hello world!") ;
return 0;
}
Notice that the extern "C" is required for C++ projects.
Compiling the project is straightforward. From the command prompt type:
$ g++ main.cpp -o vlfeat-test -IVLROOT -LVLROOT/bin/a64/ -lvl
In this example, replace VLROOT with the path to your VLFeat
installation and replace a64 with your architecture
(a64 for 64 bit linux, glx for 32 bit linux).
