CGAL users discussion list

[Gaurav Kanade <>]

Hello
I am a new user of CGAL and have some problems with issues involving
linking libraries. I use the command

g++ -lCGAL -lCGAL_Core Scenario.cpp
/usr/bin/ld: /tmp/ccydV8IU.o: undefined reference to symbol 'mpfr_set_q'
/usr/bin/ld: note: 'mpfr_set_q' is defined in DSO
/usr/lib64/libmpfr.so.1 so try adding it to the linker command line
/usr/lib64/libmpfr.so.1: could not read symbols: Invalid operation
collect2: ld returned 1 exit status

Now based upon the suggestion it gave me I tried to link the file
libmpfr.so.1 and then it gives

g++ -lCGAL -lCGAL_Core -llibmpfr.so.1 Scenario.cpp
/usr/bin/ld: cannot find -llibmpfr.so.1
collect2: ld returned 1 exit status

I know that the file exists in /usr/lib64 as I can see it there ...
any idea how to resolve this ?

Thanks and sorry for the trouble if this is already asked ...

Gaurav
