I have a system very similar to yours... Ubuntu 7.10, Eclipse 22.214.171.124 with the C++ plugin (cdt), but I haven't used the igraph library in Eclipse yet. I'd be appreciative to know how you have integrated the igraph library into Eclipse.
Also, as I understand it, when using igraph library functions, there is a run time library component. When debugging, can the debugger locate and display (in Eclipse) igraph source code when a bug involves the run time igraph library component?

Hello Gabor, thank you for your reply. I am working on Ubuntu Linux version 7.10 (Linux kernel 2.6.22-14). The gcc version on my system is: 4.1.3 (20070929) The full output of gcc -v is: Using built-in specs.

It is quite easy to set up igraph in Eclipse. If this is useful I can send you my configuration. When I try to compile the example igraph_cliques.c in Eclipse, I get the following console output: **** Build of configuration Debug for project igraph-clique-proj **** make all Building file: ../src/igraph-clique-proj.cpp Invoking: GCC C++ Compiler g++ -I/usr/local/include/igraph -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/igraph-clique-proj.d" -MT"src/igraph-clique-proj.d" -o"src/igraph-clique-proj.o" "../src/igraph-clique-proj.cpp" ../src/igraph-clique-proj.cpp: In function 'int main()': ../src/igraph-clique-proj.cpp:48: warning: comparison between signed and unsigned integer expressions ../src/igraph-clique-proj.cpp:58: error: invalid conversion from 'void*' to 'igraph_vector_t*' make: *** [src/igraph-clique-proj.o] Error 1 Line 58 is: v=igraph_vector_ptr_e(&result,i); If you need other information, let me know.

What we don't have however is your operating system, the version of your compiler, your compile flags, the detailed error message. Please send us these and then we can help. Right now I can only say that for me it works on Linux, Windows and OSX with recent versions of gcc (eg. i've used 4.1.2 on my Linux system).
