while building Lua on windows by mingw491 it gives an undefined reference error. Following is the output:

I'm using mingw (491) on windows7 and I want to link it with Qt.
I found the answer. I've just used g++ instead of gcc and it fixed :)
The solution is to add the following line in src/Makefile:
CXX= gcc -std=gnu99
Or more generally to set CXX to whichever value CC is set.
This problem occurs because the Lua make files rely on the implicit rules and variables of GNU make (source). Which means that make should call $(CC) -c $(CFLAGS) $(CPPFLAGS) to build .o files from .c files.
However mingw make calls $(CXX) -c $(CFLAGS) $(CPPFLAGS). This means that Lua C code is compiled as C++. The issue reveals itself at linktime as here gcc is used and it fails to find C++ related dependencies. So from here you have 2 solutions:
Replace gcc by g++ at link time (Mosi's solution). Which you should NOT do!
As you will end up with C++ symbols with mangled names and you will not be able to use your DLL in anything else than C++ projects. Although your code will not be portable as any other Lua DLL will not have C++ symbols.
Replace g++ by gcc during compilation (see above). You will end up with valid C symbols in your DLL.

I searched this on Stackoverflow before asking and most of the answers just pointed to linking the libraries properly in project settings and I have done that as one can see in the code above but still keeps giving the error and I don't know what am i missing??
A little Help would be appreciated...
Thank You
/usr/lib/libboost_system.so.1.60.0: error adding symbols: DSO missing from command line
This DSO error means that libboost_system is missing from the command line.
You should also add:
-lboost_system
to your command line just like -lcpprest
This can happen if you reference libraries in the wrong order. I have a personal library that depends on -lboost_system, but I had listed my own library after the boost library and was getting this error. I moved my personal library to the front of the list, and the error went away.

Following this close question : program linking fails when using custom built gcc, I purge and reinstall libstdc++-4.9-dev.
I'm running
Ubuntu 15.04 with gcc (Ubuntu 4.9.2-10ubuntu13) 4.9.2
How can I resolve this issue ?
It's because you link using gcc instead of g++. The difference is that the g++ command adds the C++ runtime library when linking.
You can either change from using gcc to g++, or manually link with the C++ runtme library by adding -lstdc++.
Recently I need to use zlib in programming on Ubuntu and here I have a problem.
I wrote a small program to test zlib functions and I built it in Eclipse.
I found it can be compiled but there were some linking errors like this:
main.cpp:27: undefined reference to `compress'
main.cpp:38: undefined reference to `uncompress'
What should I do with this? If this is because there is no library file?
Can anyone give some help? Thanks a lot!

Try:

Also, use -lz on the compile/link command.
You need to link youe source to zlib.Build your code as follows
gcc main.cpp -lz
I am attempting to compile an example application for a USB camera (mvBlueFOX) sold by Matrix Vision. They provide me with the source code for the application, a make file, and a set of pre-compiled shared libraries. However, the make file fails to successfully build an executable. A "make" returns:

A simplified version of the link command:
g++ -o LiveSnap x86/LiveSnap.o -lmvDeviceManager -ldl
Still returns:
../../../lib/x86/libmvPropHandling.so: undefined reference to `dlsym'
../../../lib/x86/libmvPropHandling.so: undefined reference to `dlopen'
../../../lib/x86/libmvPropHandling.so: undefined reference to `dlclose'
libdl.so is being found, however the process still fails. Is this an issue with my version of libdl or is there another problem?
If your gcc version is above 4.6.2 just add the flag '-Wl,--no-as-needed' before -lmvDeviceManager
For those interested in a work around to this problem, I was able to successfully build and run a newer version of the code that I downloaded from the Movie-Matrix website. The version provided on the CD with my camera was 1.2.22 while the version from the website was 2.5.2. Why the older version fails to build is still unknown, but the problem seems to be solved in newer versions of the software.

When I tried to find -Werror in make files present at /home/mypc/pjproject-1.4.5/pjnath/build, $(PJDIR)/build.mak and $(PJDIR)/build/common.mak its not present there anybody know where it could be ?
It seems that the pj* can't build the neccessary libaries - for a simple fix try to locate the line in /home/mypc/pjproject-1.4.5/build.mak where -Werror is added to $(APP_CFLAGS) and remove it (the -Werror, not the whole line if other flags are added :).
Alternatively apply the fix suggested by gcc on line 230 in src/pjnath/stun_session.c.
edit:
Just read that you found no -Werror. Could you either paste line 230 of stun_session.c or the make-files somewhere?
The source line would be preferred.
