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