I went through this tutorial on how to install Mesa(OpenGL). Everything works as described. But when I try to put the build command, which works perfectly, into a makefile it doesn't.
This is my makefile:
all:
gcc -lglut -IGL -IGLEW -IGLU main.c -o OpenGLExample
If I enter make, I get:
gcc -lglut -IGL -IGLEW -IGLU main.c -o OpenGLExample

make: *** [all] Error 1
I'm using Ubuntu instead of Mint as in the tutorial.
What is it that I'm doing wrong?
You didn't pass OpenGl libraries to the linker. Instead of I you should type l:
all:
gcc main.c -lglut -lGL -lGLEW -lGLU -o OpenGLExample
You should also pass directory where your compiler can find OpenGL header files, this can be done with -I, and probably also an option (or options) specifying where the linker should look for the libraries (-L).

I am running an OpenGL C++ file with fragment and vertex files.
I am on Ubuntu 18.04.
The problem is that when I link with g++ command I get errors :
my first linking command was :
g++ -o proj prog.cpp -lGL -lm
and I am getting these errors :

The command I tried :
g++ -o proj prog.cpp -lGLEW -lm -lGLU -lglut
g++ -o proj prog.cpp -lGL -lGLEW -lm
g++ -o proj prog.cpp -lGLEW -lGL -lm

include :
#include <iostream>
#define GLEW_STATIC
#include <GL/glew.h>
#include <GLFW/glfw3.h>
#include "Shader.h"
Update :
here is what I am getting now

This question already has answers here:
undefined reference to boost::system::system_category() when compiling
(9 answers)
Closed 7 years ago.
I'm trying to get select boost modules built and into my code as static libraries for what we need for our project. I seem to be able to get them to build using their Boost.Build system, and my project will compile using boost shared libraries, but when I try to link static, they break.
I built Boost using the following:
./b2 link=static variant=release threading=multi --with-iostreams --with-system --with-timer --ignore-site-config
Which give success
The Boost C++ Libraries were successfully built!
The following directory should be added to compiler include paths:
/home/mike/dev/cpp/boost_1_60_0
The following directory should be added to linker library paths:
/home/mike/dev/cpp/boost_1_60_0/stage/lib
Then I try to compile using my makefile with autotools:
tunnel_CPPFLAGS = -march=native -pipe -funroll-loops -fomit-frame-pointer -fforce-addr -fprefetch-loop-arrays -Wall -std=c++0x -I/home/mike/dev/cpp/boost_1_60_0/
tunnel_SOURCES = tunneller/tunnel.cpp config.cpp util.cpp tunneller/remoteclient.cpp tunneller/localclient.cpp
tunnel_LDADD = -lcrypto -lssl
tunnel_LDFLAGS = -pthread -Wl,-Bstatic -L/home/mike/dev/cpp/boost_1_60_0/stage/lib -lboost_iostreams -lboost_timer -lboost_system -Wl,-Bdynamic
Which returns this fantastic error:

What am I missing to get this to compile properly?
The problem is not when compiling, it is when it trying to link.
The order in which -l option is given matters So, try giving -lboost_system as first in -l options.
-pthread -Wl,-Bstatic -L/home/mike/dev/cpp/boost_1_60_0/stage/lib -lboost_system -lboost_iostreams -lboost_timer -Wl,-Bdynamic

I could not find any appropriate solution to this error.
Thank you for your helping.
I found the solution,
In the makefile change the order of the library references in this order:
LOADLIBES = -lX11 -ltiff -ljpeg -lpng -llapack -lGLU -lGL -ldc1394 -L -lXext -pthread
I did two things.
First, I added an extra -lX11 in the following places. The new lines look like this -
thirdparty/libcvd/installfiles/configure: LIBS="-lX11 -lX11 $LIBS"
thirdparty/libcvd/installfiles/configure: LIBS="$LIBS -L$x_libraries -lX11 -lX11 -lXext"
thirdparty/libcvd/installfiles/configure.in: APPEND(LIBS, [-L$x_libraries -lX11 -lX11 -lXext])
Next, I followed this answer of installing all 3 mentioned below (note: you need to install liblapack-dev as well. I had just liblapack3 installed but needed dev as well).

Your problem is here:
g++ -o progs/se3_exp progs/se3_exp.o -L. -lcvd [...] -ldc1394 -L -lX11 -lXext -pthread
Unlike the first -L., the second library path (-L) option has no path argument after it, so it steals whatever comes next to use as an (unlikely!) path. To really fix this problem, you need to look at your Makefile's LOADLIBES definition and figure out how this incomplete -L option is getting into it. Most likely, the Makefile has ...-L$(SOME_PATH)... or similar, and the SOME_PATH variable is unexpectedly empty.
I have been running through a few tutorials of boost and the libraries it has.
I ran through the basic tutorial for boost:
http://www.boost.org/doc/libs/1_52_0/more/getting_started/unix-variants.html
and it worked fine. I am having issues with the asio tutorial:
http://www.boost.org/doc/libs/1_50_0/doc/html/boost_asio/tutorial/tutdaytime1/src.html
It looks like linking errors, but I am including the same path as before:
g++ -I /usr/local/boost_1_52_0 test.cpp -o example

assuming you have installed your boost libraries in your /usr/lib directory and boost header files in /usr/include/boost and you have saved your code in a file named daytime1.cpp, you have to use the following command to compile the source code you have linked to:
$ g++ daytime1.cpp -o daytime -L /usr/lib/ -lboost_system -lboost_thread -lpthread
