Trying to build 5.8.0 on OS X 10.2.4 with Apple's December development kit. ../../../miniperl "-I../../../lib" ../bin/enc2xs -"Q" -"O" -o byte_t.c -f byte_t.fnm ... Reading cp856 (cp856) make[2]: *** [byte_t.c] Segmentation fault make[2]: *** Deleting file `byte_t.c' make[1]: *** [subdirs] Error 2 make: *** [lib/auto/Encode/Encode.bundle] Error 2 That's miniperl segfaulting. This is with 64 bit ints and perl's malloc. Everything else default. I'm going to try it again with debugging and figure out what's going on. Same problem in bleadperl. $ gcc -v Reading specs from /usr/libexec/gcc/darwin/ppc/3.1/specs Thread model: posix Apple Computer, Inc.
