Dear Enrico,
your invoking g++ the wrong way. First, the -L option wants the path to a directory (where to look for library files), not the complete path leading to a specific *.a file. Secondly, you must link with the PPL, the C++ interface of GMP, and with GMP itself, and you need 3 -l switches to specify that. Summing it up, your compilation command should be something like
g++ -g constraints1.cc -I ../ppl05/include/ -L ../ppl05/lib/ -lppl -lgmpxx -lgmp
assuming that you have installed both GMP and PPL in ../ppl05. If GMP has been installed elsewhere, you will have to add the corresponding -I and -L switches. Please, let us know if this solves your problem. All the best,
Roberto
Dear Roberto, thanks a lot for your help, now it seems that the libreries are called correctly. I have some problems with 'print.hh' and 'set_handlers()' functions again. I rename file 'ppl.hh' in 'ppl_install.hh' (the compiler doesn't generate 'ppl_install.hh' file).
When I try to compile some tests, like addconstraint1.cc, the compiler gives these problems:
/tmp/cceoSN0Q.o(.text+0x16): In function `main': /home/enrico/Tesi/Ppl/ppl-0.5/tests/ppl_install.hh:2157: undefined reference to `set_handlers()'

I hope that this is the last time that I disturb you.
Best regards,
Enrico
