Raymond Toy pushed to branch master at cmucl / cmucl Commits: 9245bc06 by Raymond Toy at 2014-11-15T17:04:49Z First cut at simplifying unix.lisp. * Moved original unix.lisp to src/contrib/unix/unix.lisp. * Copied just enough from unix.lisp to compile and load the first build. (Second build doesn't yet work.) * Trimmed exports.lisp to the current UNIX symbols. This is currently for Darwin/x86. Nothing else is supported yet. - - - - - fdc539f9 by Raymond Toy at 2014-11-16T09:22:39Z Add more stuff to unix.lisp. Not yet enough to compile cmucl. - - - - - fe8f398c by Raymond Toy at 2014-11-16T14:49:08Z Add more unix stuff. * asdf wants unix-rmdir * Add some missing structs. - - - - - 836d21bf by Raymond Toy at 2014-11-16T20:20:04Z Add more unix functions, for motif and hemlock. - - - - - a71198af by Raymond Toy at 2014-11-16T20:20:23Z Fix indentation. - - - - - 11ecbb80 by Raymond Toy at 2014-11-16T21:14:42Z More support for hemlock. - - - - - db12154d by Raymond Toy at 2014-11-18T21:35:46Z Add UNIX-SYMLINK.

This is necessary to be able to read/write/stat files that +;; are larger than 2GB on a 32-bit system. From a C program, defining +;; a preprocessor macro _LARGEFILE64_SOURCE makes the preproccessor +;; replace a call to open() by open64(), and similarly for stat, +;; fstat, lstat, lseek, readdir and friends. Furthermore, certain data +;; types, that are normally 32 bits wide, are replaced by 64-bit wide +;; equivalents: off_t -> off64_t etc. The libc.so fiddles around with +;; weak symbols to support this mess. +;; +;; From CMUCL, we make FFI calls to the xxx64 functions, and use the +;; 64-bit wide versions of the data structures. The most ugly aspect +;; is that some of the stat functions are not available via dlsym, so +;; we reference them explicitly from linux-stubs.S. Another amusing +;; fact is that on glibc 2.2, stat64() returns a struct stat with a +;; 32-bit ino_t, whereas readdir64() returns a struct dirent that +;; contains a 64-bit ino_t. On glibc 2.1, OTOH, both stat64 and +;; readdir64 use structs with 32-bit ino_t. +;; +;; The current version deals with this by going with the glibc 2.2 +;; definitions, unless the keyword :glibc2.1 also occurs on *features*, +;; in addition to :glibc2, in which case we go with the glibc 2.1 +;; definitions. Note that binaries compiled against glibc 2.1 do in +;; fact work fine on glibc 2.2, because readdir64 is available in both +;; glibc 2.1 and glibc 2.2 versions in glibc 2.2, disambiguated through +;; ELF symbol versioning. We use an entry for readdir64 in linux-stubs.S +;; in order to force usage of the correct version of readdir64 at runtime. +;; +;; So in order to compile for glibc 2.2 and newer, just compile CMUCL +;; on a glibc 2.2 system, and make sure that :glibc2.1 doesn't appear +;; on the *features* list.
