I am trying to compile a simple example program that depends on a shared library (so) that depends on liblua51.so. My source file is example.c and here is the command I am using to compile it (it is written in C)
cc -Wall -fPIC -ldl -o a.out -I./ste-linux/ste-interface-files/c/ -L./ste-linux/ste-shared-libraries/ example.c -lm -llua51 -lste -lm -ldl
I am getting the following errors:
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `sinh'
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `ceil'
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `atan2'

I have read a bunch of other threads on stackoverflow saying adding the -lm flag will fix this, but no matter where I put the -L and -lm -ldl in the command, these undefined references will not go away.
I am trying to compile this lib on ubuntu 12.04 LTS
Help please
The issue was the shared library I was using was built with a different version of GCC. After I downgrade from Ubuntu 11.04 (from 12.04 LTS) it was resolved.

I don't usually run ubuntu, but same code works on my fedora(slightly older version of libudev) and also a pi which runs wheezy (older version of libudev).
The order is important, put the library name at the end of the compilation / linking line:
$ gcc -Wall -o test test.c -ludev
The error you see is a linker error, not because of any installation issues.. Move -ludev to the end of the command line option:
gcc -Wall -o test test.c -ludev
I am trying to compile an example program from the Intel MKL library (/opt/intel/mkl/examples/versionqueryc/). I copied the source code (C-file) to a new directory. I then went and tried to build this example using CMake.
In the course of debugging this, I am stuck when trying to use the following command (isolated from cmake by now).
It doesn't find the Math library but I have -lm included in the linking. So what is going on?

Put -lm as the last parameter, the order of parameters is important while linking.
I'm new to linear programming and C. I am trying to use the lp_solve library to solve a linear equation. The problem is I can't get the demo code to work.
As described in the documentation, I downloaded lp_solve_5.5_dev.gz to my Linux machine. I extracted the files into the same folder as my code and tried to compile:

I understand that the lp_solve libraries are not loaded in my code. Can you please tell me how I can properly link the lp_solve libraries?
You're just missing some compiler flags to include the proper libraries. As danielko said, a quick google search on the missing libraries brings up some suggestions. E.g.
Linux c++ error: undefined reference to 'dlopen'
http://sourceforge.net/p/dev-cpp/discussion/48211/thread/3bd8b8a1
These suggest your compilation should be something more like:
cc -o demo demo.c -ldl -llpsolve55
and the lpsolve documentation suggests a command that includes the project directory such as:
cc -I/lp_solve_5.5 -I/lp_solve_5.5/bfp -I/lp_solve_5.5/bfp/bfp_etaPFI -I/lp_solve_5.5/colamd $src -o MyExe.exe -lm -ldl

I have passed the libraries to g++ as can be seen in the compiler invocation.
Do I have to install GL separately, but in that case why don't I get an error on #include <GL/gl.h>?
I am porting an application that I developed in Linux to Windows and am having some issues when building the application. After making the necessary code changes, everything compiles fine (and when built as a debug build in Visual Studio, runs without any issues). I need to build this in MinGW, and I'm having linker errors when I try to link it against liboauth, which is also required for my project.
The command and its output are as follows:

I have all of the required libraries in the lib path, and for some reason liboauth just cannot find the references to libssl and libcrypto. This all builds fine in Linux. Any ideas?
Update
Based on responses, I have updated my linker command so as to link the libraries in a different order. My new command is as follows:
gcc -o application application.o service.o util.o json.o api.o -Lc:/mingw/msys/1.0/local/lib -loauth -ljansson -lcurl -lssl -lcrypto
This fixes this previous problem and presents a new set of linker errors:
