检查 OpenCV 是否使用 C++ 代码中的 GTK 支持编译

Question

My problem is the same as in: OpenCV GTK+2.x error

I am facing this problem deploying my code in systems where OpenCV is available but has not been installed with GTK support. I have no control over OpenCV installation in these systems.

How can I discriminate where OpenCV is compiled without GTK support from C++ code, possibly without relying on catching exceptions? I would simply avoid calling imshow in these cases.

Answer 1

you could check dependencies by executing ldd opencv-lib and parse the output using eg regex to check for some kind of gtk libs.

Or use this approach: linux/gcc: ldd functionality from inside a C/C++ program

setenv("LD_TRACE_LOADED_OBJECTS", "1", 1); FILE *ldd = popen("/lib/libz.so");
