Some notes on installation on Linux X86

Since July 2000 Doris can be installed to Linux X86 systems. The code needed some changes. Please refer to the general problems section as well.

• Byte order on X86 systems. Use the functions htonl and htons to read the record length and data of the SLC volume, leader, and data file.
• File io.
  • (gcc compiler only?) ios::ate does not act as expected. It should open an input file stream at the end, but it does not. ios::app (ofstream class) does work, as does a file.seekg(0,ios::end);
  • ios::in (or out) has to be set, even for statements like ifstream ifile(ios::nocreate); The default and logical, that a file is an input stream if it is declared ifstream, is not true for gcc compiler.
• strcmp. The statement strcmp(word,' $\backslash$0') gives a memory fault if tested.
