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

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 :

When I googled, I found this post : undefined reference to `__glewCreateShader`
and according to the post, I changed the command to :

The long list of errors is reduced but still :

I viewed several posts and they almost say the same thing
OpenGL library not linking
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
g++ -o proj prog.cpp -lGLEW -lopengl32 -lm
g++ prog.cpp -lGL -lGLU -lGLEW -lGLFW -lm
g++ prog.cpp -lGL -lGLU -lGLEW -lglut -lm -o proj
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
g++ -o proj sample.cpp libglut.a -lGL -lm
/usr/bin/ld: libglut.a(glut_event.o): undefined reference to symbol 'XWithdrawWindow'
//usr/lib/x86_64-linux-gnu/libX11.so.6: error adding symbols: DSO missing from command line

Please tell me what am I doing wrong.

It looks like it isn't linking to some basic libraries that are part of the OS?
Details:
gcc --version --> 5.4.0 20160609
ldd --version --> 2.23
OS --> Ubuntu 16.04 x64, 4.8.0-36-generic kernel
You seem to be missing a link to the pthread library. Add -pthread to your compilation command:
g++ -o main main.o -pthread -lwdt_dio
Checking the man page for sem_wait(3) shows:
Link with -pthread.
Note: sem_wait was selected randomly, all of them should specify that
If you read the errors closely it says that the undefined comes from libwdt_dio.so. It also says to which function you have an undefined reference.
In this particular case, it is the pthread library. It should probably be mentioned as a dependency in WDT lib documentation.
You can add -pthread to your g++ command if you're compiling through the command line.

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
Getting this error from a cpp library I'm trying to port from Linux to Windows, using code::blocks. I'm new to c++ in general but especially new to Windows and CB.
I'm pretty sure I have added the system library accordingly, by which I mean I have compiled it using:
.\b2 -j 8 variant=release link=shared threading=single
Then gone to the lib directory, found boost_system-vc120-1_55.dll and renamed it boost_system.dll
The added F:\plus\boost\boost_1_55_0\stage\lib to the Build options, search directories, linker. (And F:\plus\boost\boost_1_55_0\ in search directories, compiler)
The -lboost_system is after the cpp files in the compile command, although for some reason it's listed twice, but I tried compiling in command prompt without the first one and gave same error.
This is the build output I get:

Any ideas? Thanks!
I've been trying to make a static library out of this: https://github.com/onlinecity/cpp-smpp , as I'd like to make a single file executable that uses it.
So far I have gone into src/smpp/ and created the .o files with:
g++-5 -c *.cpp -std=c++11 -I.
Then made them into an .a file with:
ar rvs libsmpp.a *.o
Then I'm trying to compile a small main.cpp file that uses the library with this:
g++-5 main.cpp -I/usr/local/include -static libsmpp.a -lboost_system -lboost_regex -lboost_date_time -lpthread -lm -lglog -lgflags -std=c++11
And I get some undefined reference errors:

It compiles fine when I link to a dynamic version of the smpp library, although that's made using the cmake files included with the smpp lib. I didn't know how to modify them to output a static library, so I just used the g++ command at the top, and added the libraries listed in them (like glog) in the main.cpp compile command.
The "undefined reference to google::logMessage" seems especially strange, as I'm pretty sure thats part of glog, which is definitely loaded and included in the smppclient.cpp file itself.
Any ideas? Thanks.
