.TH RANLIB 1 .SH NAME ranlib \- convert archives to random libraries .SH SYNOPSIS .B ranlib archive ... .SH DESCRIPTION .I Ranlib converts each .I archive to a form which can be loaded more rapidly by the loader, by adding a table of contents named .B _\^_.SYMDEF to the beginning of the archive. It uses .IR ar (1) to reconstruct the archive, so that sufficient temporary file space must be available in the file system containing the current directory. .SH SEE ALSO ld(1), ar(1), lorder(1) .SH BUGS Because generation of a library by .I ar and randomization by .I ranlib are separate, phase errors are possible. The loader .I ld warns when the modification date of a library is more recent than the creation of its dictionary; but this means you get the warning even if you only copy the library.
