I need help with compilation of P3DFFT. I'm literally lost in the process, because the compiler is complaining about "undefined reference" to lots of symbols, but those symbols are present in the libraries.
My command:
mpicc -g -O2 -I../../include -L/home/martin/fftw3/libs -lfftw3 /home/martin/p3dfft/build/libp3dfft.a driver_rand.c -o driver_rand
Compiler output:

Do you have ANY idea what am I doing wrong?
I'm not familiar with your particular compiler, but I think you may need to correct the order of the source file and the libraries on your command line, i.e.
mpicc -g -O2 -I../../include -L/home/martin/fftw3/libs -lfftw3 /home/martin/p3dfft/build/libp3dfft.a driver_rand.c -o driver_rand
should probably be:
mpicc -g -O2 -I../../include driver_rand.c /home/martin/p3dfft/build/libp3dfft.a -L/home/martin/fftw3/libs -lfftw3 -o driver_rand
I'm attempting to follow the steps on http://llvm.org/docs/tutorial/LangImpl3.html to build the example.

Why am I getting "undefined reference to `dladdr'" even with -ldl for this simple program?
I've ended up with the command
clang++ -D__STDC_CONSTANT_MACROS -D__STDC_LIMIT_MACROS -std=c++11 -g -O3 toy.cpp `llvm-config --libs core --cppflags --ldflags` -o toy

Am I missing a library, or is some of the order incorrect?
I believe you need to link with -lpthread or just -pthread
I'm trying to develop a packet analyzer with CUDA support for pattern matching. I'm using GTK+ for GUI creation but I am not able to compile the GUI file together with the cuda files. How to write makefile for this case?
The project is having two parts: 1. Analyzer 2. GUI
Analyzer consists of many .c,.h files and one .cu file.
GUI part has only one file gui.c
I have included packet_analyzer.h in gui.c.
I tried the following makefile

You need to link with the CUDA runtime library. Add -lcudart to your link command (and CUDA lib path if necessary).
It's the nvcc -lpcap -lpthread $(ANALYZER) -o packet_analyzer.o line that's failing, right? With the -o option, you're telling it to build a complete executable, not just the object files. It needs a main function to do that, which I presume you don't have in any of the $(ANALYZER) files. Instead, try compiling all the sources with the -c flag (like you've done with gcc for gui.c), and then wrap it all together and link it with the other gcc command.
I tried to put up an example using c++ for accessing Cassandra, and so Using Thrift.
Copying the example, I had this strange situation:

Then, with some Voodoo I tried to move the -l switch at the end of the linking order, and magically ...
storm#debian:~/Script/goh-server/src/cassandra$ g++ *.o -o prova -lthrift
storm#debian:~/Script/goh-server/src/cassandra$
On the Thrift documentation, the -l switch is put in the beginning, and in fact automake DOES put it before the '*.o's and -o switch.
What's wrong with it ?
Edit:
In fact is not true that automake put -l flags in the beginning. It does put them in the end in the linking stage. Still: why does the order matter ?
It matters. -llibrary must follow everything that references the library.
If you have circular references between static libraries, you end up with -llibrary twice.

How to remove the above error
You want -lboost_system.
The Boost build system builds multiple variants of a single library. For example, a thread safe version of that library is -lboost_system-mt. To understand how the variants are named, see the Boost documentation.
