| 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. |
| 160 | dnl |
| 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. |
| 165 | dnl |
| 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 |
| 168 | dnl |
| 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. |
| 172 | dnl |
| 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. |
