OGDF is a self-contained C++ library for graph algorithms, in particular for (but not restricted to) automatic graph drawing. The latest version of ogdf is called Dogwood (February 2, 2022).
I compiled the file (ex1.cpp) using the command.
g++ -I/home/Desktop/OGDF -I/home/Desktop/OGDF/include/ogdf -o ex1.out -c ex1.cpp
Then the file ex1.out was created in the same directory. I tried to run it by ./ex1.out. But it failed.
I am an ogdf beginner and I don't know how to successfully compile and run a c++ program that contains the ogdf library. Although there was a similar post 8 years ago. But it doesn't seem to solve my problem. Probably due to too much time and version updates.
Edit Thanks quentin for the tip. I removed the -c.
g++ -I/home/Desktop/OGDF -I/home/Desktop/OGDF/include -o ex1.out ex1.cpp
But got the following error.

I don't know if I need to add more additional dependencies. I have read the build guide of odgf below. When I run it, it still reports an error.
c++ -I/home/Desktop/OGDF -I/home/Desktop/OGDF/include/ogdf -o ex1.o -c ex1.cpp
c++ -o output_binary -L/home/Desktop/OGDF ex1.o -lOGDF -lCOIN
Say OGDF and COIN cannot be found.
//ex1.cpp
#include <ogdf/basic/GraphAttributes.h>
#include <ogdf/fileformats/GraphIO.h>
using namespace ogdf;
int main() {
Graph G;
GraphAttributes GA(G,
GraphAttributes::nodeGraphics | GraphAttributes::edgeGraphics);
const int LEN = 11;
for (int i = 1; i < LEN; ++i) {
node left = G.newNode();
GA.x(left) = -5 * (i + 1);
GA.y(left) = -20 * i;
GA.width(left) = 10 * (i + 1);
GA.height(left) = 15;
node bottom = G.newNode();
GA.x(bottom) = 20 * (LEN - i);
GA.y(bottom) = 5 * (LEN + 1 - i);
GA.width(bottom) = 15;
GA.height(bottom) = 10 * (LEN + 1 - i);
edge e = G.newEdge(left, bottom);
DPolyline &p = GA.bends(e);
p.pushBack(DPoint(10, -20 * i));
p.pushBack(DPoint(20 * (LEN - i), -10));
}
GraphIO::write(GA, "output-manual.gml", GraphIO::writeGML);
GraphIO::write(GA, "output-manual.svg", GraphIO::drawSVG);
return 0;
}
