180 dnl Added the following configure option in January 2008 following
181 dnl investigation of problems with "64" system and library calls on
182 dnl Darwin (MacOS X). The libguile code (_scm.h) assumes that if a
183 dnl system has stat64, it will have all the other 64 APIs too; but on
184 dnl Darwin, stat64 is there but other APIs are missing.
186 dnl It also appears, from the Darwin docs, that most system call APIs
187 dnl there (i.e. the traditional ones _without_ "64" in their names) have
188 dnl been 64-bit-capable for a long time now, so it isn't necessary to
189 dnl use "64" versions anyway. For example, Darwin's off_t is 64-bit.
191 dnl A similar problem has been reported for HP-UX:
192 dnl http://www.nabble.com/Building-guile-1.8.2-on-hpux-td13106681.html
194 dnl Therefore, and also because a Guile without LARGEFILE64 support is
195 dnl better than no Guile at all, we provide this option to suppress
196 dnl trying to use "64" calls.
198 dnl It may be that for some 64-bit function on Darwin/HP-UX we do need
199 dnl to use a "64" call, and hence that by using --without-64-calls we're
200 dnl missing out on that. If so, someone can work on that in the future.
201 dnl For now, --without-64-calls allows Guile to build on OSs where it
202 dnl wasn't building before.
