<html> Hello everyone. I found the solution for the errors that i have listed: paulo@paulo-laptop:~$ At line 2965 of file esru_lib.F Internal Error: printf is broken At line 375 of file esru_libGTK.F Internal Error: printf is broken At line 2615 of file esru_libGTK.F Fortran runtime error: End of record They occur when during the compilation process i choose the GTK graphics library! Now i choose X11 graphics library and the errors stopped! This situation must be reviewed in futures developments. I would like to thank to everyone that helps me trying to solve these errors namely Jon Hand and Marco Manzan. Regrads, Paulo Tavares</html>
