hi, i am using pbc library in my fedora 17 64 bit os. i have installed gmp and pbc libraries. as the link describes "http://crypto.stanford.edu/pbc/howto.html" i have run the foo.c,it works fine but when i try to run paterson.c as or other examples in pbc/example directory i got these errors "./paterson: error while loading shared libraries: libpbc.so.1: cannot open shared object file: No such file or directory". but the compilation works fine. plz help me what is happening.thanks in advance.

You mean the GMP libraries that you said you could NOT install?
http://www.linuxquestions.org/questi...os-4175490893/

Again, Fedora 17 is old, unsupported, and end-of-life...you really should update to FC20. That said, your error message is VERY clear...you do not have the PBC libraries installed, since the message tells you that they aren't. You need PBC, and the PBC development libraries.

And again, you need to spell out your words, please.

how do i check gmp is installed correctly? similarly for pbc? actually i have already installed these two libraries from source using these instructions ./configure, make, make check and make install.

You read the installation instructions. You STILL haven't told us where you got those libraries, what you did to install them, etc. All you posted in your other thread was that you "got the problem resolved", but don't tell anyone HOW you resolved it.

Again, you are THREE VERSIONS behind in Fedora...update. And again, you need to install the GMP DEVELOPMENT libraries, not just the GMP software. Since you don't give any details about what you've done, where you got things, what you're doing, etc., there's not much we can tell you.

i'm sorry for not giving you enough information. actually i got the gmp library from "https://gmplib.org/" and pbc library from "http://crypto.stanford.edu/pbc/download.html". By using the following instruction i solved my problem....
1. install gmp development tools first.(yum groupinstall "Development Tools")
2. install gmp as follows..
$ ./configure--prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-bugurl=http://bugzilla.redhat.com/bugzilla --enable-bootstrap --enable-shared --enable-threads=posix --enable-checking=release --disable-build-with-cxx --disable-build-poststage1-with-cxx --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object --enable-linker-build-id --with-linker-hash-style=gnu --enable-languages=c,c++,objc,obj-c++,java,fortran,ada,go,lto --enable-plugin --enable-initfini-array --enable-java-awt=gtk --disable-dssi --with-java-home=/usr/lib/jvm/java-1.5.0-gcj-1.5.0.0/jre --enable-libgcj-multifile --enable-java-maintainer-mode --with-ecj-jar=/usr/share/java/eclipse-ecj.jar --disable-libjava-multilib --with-ppl --with-cloog --with-tune=generic --with-arch_32=i686 --build=x86_64-redhat-linux
$ make
$ make check
$make install

3. then install pbc library( for installation follow the instruction of the manual ("http://crypto.stanford.edu/pbc/manual/")

the error was resolved by changing the header of the paterson.c as #include<pbc/pbc.h> and #include<pbc/pbc_test.h>
compile as $gcc -o paterson paterson.c -lgmp -lpbc and run as $./paterson ../param/a.param
