Hello!

I receive a lot of errors when I try to compile my c++ program. I am on a Ubuntu 12.04 machine, this machine is a server that I control.

In order I had:

downloaded the source code of GLFW from official site, then followed the instruction

cd <glfw-root-dir>
mkdir build
cd build
cmake ..

after this in the "build" folder I launched the command

make

in the folder build/src I found the libglfw3.a and in the glfw folder root the /include folder.

I copied all the glfw folder into my project src/ folder, and also copied libglfw3.a in src/lib folder. In this folder I had also libGLEW.a used to my project too.

I created this Makefile for my project:

#variables
MYINC=-I/isis/AlfonsoOricchio/RayTracing/src/glfw/include -I/isis/AlfonsoOricchio/RayTracing/src/glew/include -I/isis/AlfonsoOricchio/RayTracing/src
MYCUDAINC=-I/usr/local/cuda-5.5/include/
MYLIB=-L/isis/AlfonsoOricchio/RayTracing/src/lib -L/usr/local/cuda-5.5/lib64/ 
MYCMD=-lcudart -lglfw3 -lGLEW -lGL
NVCC=/usr/local/cuda-5.5/bin/nvcc

all: myexe

myexe: render.o controls.o objloader.o shader.o Ray.o 
	g++ render.o controls.o objloader.o shader.o Ray.o $(MYLIB) $(MYCMD) -o RayTracing


Ray.o: Ray.cpp
	g++ -c $(MYINC) $(MYCUDAINC) Ray.cpp
	
controls.o: controls.cpp
	g++ -c $(MYINC) controls.cpp
	
objloader.o: objloader.cpp
	g++ -c $(MYINC) objloader.cpp

shader.o: shader.cpp
	g++ -c $(MYINC) shader.cpp

render.o:
	$(NVCC) -c -arch=sm_20 render.cu 


clean: 
	rm -rf *o RayTracing

But when I run the make, the "myexe" call give me this errors:

What Can I do?

UPDATE:

In my Makefile I modify this line as follow

MYCMD=-lcudart -lglfw3 -lX11 -lXxf86vm -lXrandr -lpthread -lXi -lGLEW -lGL

now the errors are only 2:

/isis/AlfonsoOricchio/RayTracing/src/lib/libglfw3.a(x11_time.c.o):x11_time.c:function getRawTime: error: undefined reference to 'clock_gettime'
/isis/AlfonsoOricchio/RayTracing/src/lib/libglfw3.a(x11_time.c.o):x11_time.c:function _glfwInitTimer: error: undefined reference to 'clock_gettime'

Maybe I need to link another library, but I don't find anything about that

UPDATE2:

I solved my problem. the last library to link is -lrt, so the line in my Makefile is now this

MYCMD=-lcudart -lglfw3 -lX11 -lXxf86vm -lXrandr -lpthread -lXi -lrt -lGLEW -lGL

I hope this thread can help someone :)

Hi Bregma,

I tried as you suggest. But

MYCMD=$(shell pkg-config --libs libglfw glew)

give me this errors:

g++ render.o controls.o objloader.o shader.o Ray.o -L/isis/AlfonsoOricchio/RayTracing/src/lib -L/usr/local/cuda-5.5/lib64/ -lcudart -lglfw -lGLEW -lGLU -lGL   -o RayTracing

That's because the ubuntu glfw package is old, it's 2.7 or something, while you are using 3.0.4.

To use that simply download the 3.0.4 package, install it, and then use pkg-config in the same manner as before in the makefile.

thanks for reply

I thought about that, and serching what lib I have to install, I tried to download this

sudo apt-get install libglfw3-dev

but I receive this error:

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package libglfw3-dev

Install cmake:

sudo apt-get install cmake

Download from glfw.org, unpack it to a location, enter directory, type this in terminal:

cmake .
make -j4
sudo make install

Done.

Here is my output for static linking:

pkg-config glfw3 --libs --static
-L/usr/local/lib -lglfw3 -lrt -lXrandr -lXi -lGL -lm -ldl -lXrender -ldrm -lXdamage -lX11-xcb -lxcb-glx -lxcb-dri2 -lxcb-dri3 -lxcb-present -lxcb-sync -lxshmfence -lXxf86vm -lXfixes -lXext -lX11 -lpthread -lxcb -lXau -lXdmcp

So, to use that, add the command to linking process using `` qoutes, for example: -Llib -llzo2 `pkg-config glfw3 --libs --static`

Hi followed Kaptein instruction

This is the modified Makefile

variables
MYINC=-I/isis/AlfonsoOricchio/RayTracing/src/glfw/include/ -I/isis/AlfonsoOricchio/RayTracing/src/glew/include -I/isis/AlfonsoOricchio/RayTracing/src
MYCUDAINC=-I/usr/local/cuda-5.5/include/
MYLIB=-L/usr/local/cuda-5.5/lib64/
MYCMD=$(shell pkg-config glfw3 --libs --static glew) -lcudart
NVCC=/usr/local/cuda-5.5/bin/nvcc

all: myexe

myexe: render.o controls.o objloader.o shader.o Ray.o
        g++ render.o controls.o objloader.o shader.o Ray.o $(MYLIB) $(MYCMD) -o RayTracing


Ray.o: Ray.cpp
        g++ -c $(MYINC) $(MYCUDAINC) Ray.cpp

controls.o: controls.cpp
        g++ -c $(MYINC) controls.cpp

objloader.o: objloader.cpp
        g++ -c $(MYINC) objloader.cpp

shader.o: shader.cpp
        g++ -c $(MYINC) shader.cpp

render.o:
        $(NVCC) -c -arch=sm_20 render.cu


clean:
        rm -rf *o RayTracing

Now compiling without errors. And this is my output for statit linking

g++ render.o controls.o objloader.o shader.o Ray.o -L/usr/local/cuda-5.5/lib64/ -L/usr/local/lib -lglfw3 -lrt -lXrandr -lXi -lXxf86vm -lXrender -lXfixes -lGLEW -lGLU -lGL -lm -lXext -lX11 -lpthread -lxcb -lXau -lXdmcp   -lcudart -o RayTracing

Thanks a lot guys.

I have a different problem now, when I launch the program

I have this output:

X Error of failed request:  BadRRCrtc (invalid Crtc parameter)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  22 (RRGetCrtcGammaSize)
  Crtc id in failed request: 0x1a98e00
  Serial number of failed request:  62
  Current serial number in output stream:  62

I believe because the linux server has no monitor so Xrandr fails.

but I think I have to open another post for that. Because this is a different problem, right?
