When I run Arduino 022 under Slackware 13.1 x64 I get the following error ;
/usr/libexec/gcc/avr/4.4.4/cc1plus: error while loading shared libraries: libmpfr.so.4: cannot open shared object file: No such file or directory
I installed all required 64bit libraries from here ;
I am sure experienced users can provide more insight on this. I can set serial port from interface but when I try to compile I get the above error.
