While compiling few test applications, I get the following error:
g++: error: −lboost_system: No such file or directory
g++: error: −lboost_filesystem: No such file or directory
while running the following command:
g++ -I/usr/include/boost/ -L/usr/lib/x86_64-linux-gnu/ aescuda.cpp -o test.o −lboost_system −lboost_filesystem
The libraries are installed and present in location as shown below:

Can anyone suggest where am I going wrong :(
You have a wrong character in front of the l:
−lboost_system
It should be an ASCII hyphen:
-lboost_system
This causes the compiler driver to treat the whole string as an input file name (which obviously does not exist, hence the No such file or directory error), and not as an option to be passed to the linker.
(Perhaps consider switching the terminal font.)

I'm trying to install trainable-tokenizer. I have installed all the dependencies as per the README. this is trainable-tokenizer https://github.com/jirkamarsik/trainable-tokenizer. i have installed quex.deb using installer from quex.org which is a dependency for trainable-tokenizer.

[ 6%] Building FeaturesReader with quex
Environment variable QUEX_PATH has not been defined.
error: environment variable 'QUEX_PATH' is not defined.
error: your system is 'posix'.
but still i get the same error.
I fixed the issue using the -I flag. I had to use quex -I.
I would guess that the real problem is that your python is python 3.0+
and not python 2.7 as required for Quex.
Admittedly, the error message does not tell this directly.
I have a C++ project and I´m using Eclipse CDT 3.8.1 as the IDE tool, with a workspace of 5 different projects...
One of my projects is a shared library, and at the end of compilation I want to copy its code to a test/bin directory for testing.
I´ve gone to Project Properties -> C/C++ Build -> Settings -> Build Steps and at "Post-build steps", "Command", I´ve added:
cp *.so ../../../bin
(OBS: ../../../bin is the correct path from the Debug folder - I´ve checked already).
What happens is that I get the following error on post build:
cp *.so ../../../bin
cp: cannot stat ‘*.so’: No such file or directory
I said: ok, this may be a permission problem, so I changed the post commands to:
whoami;ls -al; ls *.so;
And I got on Eclipse console:
whoami
aeidev
ls -al

ls *.so

And them I changed again to ls *.so and I got:
ls -al *.so
ls: cannot access *.so: No such file or directory
15:57:50 Build Finished (took 715ms)
It´s a very strange behaviour. In the same workspace I have a different shared library and the original cp *.so works fine...
Any ideas of what´s going on here ?
Is it a known Eclipse bug ?
Thanks for helping...
I believe the commands are not executed in a shell by default, so wildcards are not evaluated. Try executing like /bin/sh -c 'cp *.so ../../../bin/'. Also you should use Eclipse's built-in variables to copy to the desired path.

You might need to modify the include and library search paths by editing
QMAKE_INCDIR_OPENGL, QMAKE_LIBDIR_OPENGL and QMAKE_LIBS_OPENGL in
/home/.../Downloads/qt-everywhere-opensource-src-4.8.3/mkspecs/linux-g++-64.
So, i look inside /mkspecs/linux-g++-64, there's only one file, qmake.conf
#
# qmake configuration for linux-g++
#
# Written for GNU/Linux platforms that have both lib and lib64 directories,
# like the AMD Opteron.
#
MAKEFILE_GENERATOR = UNIX
TARGET_PLATFORM = unix
TEMPLATE = app
CONFIG += qt warn_on release incremental link_prl gdb_dwarf_index
QT += core gui
QMAKE_INCREMENTAL_STYLE = sublib
QMAKE_CFLAGS = -m64
QMAKE_LFLAGS = -m64
include(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g++-unix.conf)
QMAKE_LIBDIR_X11 = /usr/X11R6/lib64
QMAKE_LIBDIR_OPENGL = /usr/X11R6/lib64
I don't have a /usr/X11R6 directory, but X_11 reports that everything is OK in the output.
I add the variables:
QMAKE_INCDIR_OPENGL = /usr/include/GL
QMAKE_LIBDIR_OPENGL = /usr/lib64
QMAKE_LIBS_OPENGL = -lGLU -lGL

./configure -opengl -verbose gives the same result
in addition
glxgears
works fine.
What am I doing wrong?
I guess you might install mesa driver that provides libGL.so.1.2.0 and changes the libGL.so symbolic link.
libGL.so -> libGL.so.1.2.0
libGL.so.1 -> libGL.so.331.79
libGL.so.331.79
In /usr/lib64,
rm libGL.so
ln -s libGL.so.1 libGL.so
will give you
libGL.so -> libGL.so.1 -> libGL.so.331.79
I have these shared library files in /usr/local/lib:
libopenbabel.so
libopenbabel.so.4
libopenbabel.so.4.0.2
libopenbabel.so is actually a link to libopenbabel.so.4 and libopenbabel.so.4 is actually a link to libopenbabel.so.4.0.2
when I compile my file with this command:
g++ test.cpp -L/usr/local/lib -lopenbabel
and then try to run a.out, I get this error:
./a.out: error while loading shared libraries: libopenbabel.so.4: cannot open shared object file: No such file or directory
Implying that the compiler is finding libopenbabel.so but running into an error when following that link to libopenbabel.so.4 which is in the exact same directory. Any ideas on why this is happening / how I can fix it?

Either set your LD_LIBRARY_PATH environment variable to contain /usr/local/lib or add /usr/local/lib to /etc/ld.so.conf and run ldconfig as root.
Also, run ldd a.out to check that dynamic linking works well on your app.
Read ld-linux(8), ldconfig(8), ldd(1)
I’m trying to compile a very simple “Hello world” OpenGL 3.3 program using FreeGLUT. In all the tutorials I found, they include an header “gl3.h”. The problem is, I don’t have such header file.

In /usr/include/ I only have GL, GLES and GLES2. There is no GL3 as I found in some tutorials.
I’m running on Arch Linux x86_64 with a NVIDIA graphic card (nvidia closed-source driver).
Here is how I included OpenGL and FreeGLUT APIs in my program:
#define GL3_PROTOTYPES 1
#include <GL/gl.h>
#include <GL/freeglut.h>
But the code doesn’t compile:
$ g++ -pipe -g -Wall -Wextra -pedantic -I. -IHeaders -c Sources/Main.cpp -o Temp/Objects/Main.o
Sources/Main.cpp: In function ‘int main(int, char**)’:
Sources/Main.cpp:107:59: error: ‘glVertexAttribPointer’ was not declared in this scope
Sources/Main.cpp:108:30: error: ‘glEnableVertexAttribArray’ was not declared in this scope
Sources/Main.cpp:114:35: error: ‘glUseProgram’ was not declared in this scope
Sources/Main.cpp:138:31: error: ‘glDisableVertexAttribArray’ was not declared in this scope
It seems I included the OpenGL 2 headers! But, again, I didn’t find any OpenGL 3 headers on my system, I looked at the Arch repository and AUR, unsuccessfully.
Thank you for your help!
You don't need a GL3.h, the GL3.h just got rid of all deprecated features. So just include gl.h instead of gl3.h. Downloading and manually copyieng into /usr/include/GL/ is not a real solution, it works yes, but what happens if the add to the mesa package the gl3.h? You're package manager will find conflicts. Better you add the gl3.h to your project or into your home directory and add it to the $PATh or use the -I flag.
If you grep for glVertexAttribPointer, glEnableVertexAttribArray, glUseProgram and glDisableVertexAttribArray, you will find that they are included in glext.h and glew.h. Try to include one of these headers and compile again.
