Hi I have been looking at the problem of the compilation on the PowerPC and started looking at some of the compilation errors too. 1. thpoint.cxx:446: warning: `.' not followed by `*' or digit in format thats because you have at this line the following... sprintf(buff,"%0.f",this->xsize); should that be instead the following? sprintf(buff,"%.0f",this->xsize); 2. The following is more serious. thpoint.cxx:731: warning: assignment of negative value `-1' to `char' void thpoint_parse_value(int & sv, double & dv, bool & qw, char & sign, char * str) and later on.... case '-': sign = -1; str++; break; OK my programming skills are rudimentary but if you assign a negative value to a character pointer then the variable will give a different value depending whether the operating system is 32 or 64 bit. My Alpha is 64 bit. The compiler warns about it and rightly so. 3. I have tracked down where the strange string comes from when I run ./therion -v therion$ ./therion -v therion gduxs:l:qLvhip: it's from thcmdline.cxx where it uses the getopt routines. oc = getopt_long (argc, argv, "gduxs:l:qLvhip:", thlong_options, &oindex); I read the man 3 page on getopt and so now I know what the gduxs:l:qLvhip: string is -- never used getopt myself. So somehow instead of the version string being returned its returning the argument to the getopt_long function ! eeeewwww :-) The version of getopt on my Ti PowerBook here running Debian 3.0 is therion$ getopt --version getopt (enhanced) 1.1.2 Mike -- Mike Lake Caver, Linux enthusiast and interested in anything technical.
