155 dnl Added the following configure option in January 2008 following
156 dnl investigation of problems with "64" system and library calls on
157 dnl Darwin (MacOS X). The libguile code (_scm.h) assumes that if a
158 dnl system has stat64, it will have all the other 64 APIs too; but on
159 dnl Darwin, stat64 is there but other APIs are missing.
161 dnl It also appears, from the Darwin docs, that most system call APIs
162 dnl there (i.e. the traditional ones _without_ "64" in their names) have
163 dnl been 64-bit-capable for a long time now, so it isn't necessary to
164 dnl use "64" versions anyway. For example, Darwin's off_t is 64-bit.
166 dnl A similar problem has been reported for HP-UX:
167 dnl http://www.nabble.com/Building-guile-1.8.2-on-hpux-td13106681.html
169 dnl Therefore, and also because a Guile without LARGEFILE64 support is
170 dnl better than no Guile at all, we provide this option to suppress
171 dnl trying to use "64" calls.
173 dnl It may be that for some 64-bit function on Darwin/HP-UX we do need
174 dnl to use a "64" call, and hence that by using --without-64-calls we're
175 dnl missing out on that. If so, someone can work on that in the future.
176 dnl For now, --without-64-calls allows Guile to build on OSs where it
177 dnl wasn't building before.
