I was able to get it to build and for all tests to pass by forcing to only look for e2fs and to ignore the error message in try_e2fs(). That error is "wrong result: 'uuid'". Not sure where it comes from.

To be clear, it works with this patch, though I suspect it's not a good idea to ignore the "wrong result" error: --- Makefile.PL.orig 2015-05-12 16:27:12.000000000 -0700 +++ Makefile.PL 2015-05-12 16:27:14.000000000 -0700 @@ -105,7 +105,7 @@ return 0; /, )}; - if ($@) { my $L = length $@; print "# ===> Err($L): \"$@\"\n"; return 0 } + if ($@ && $@ !~ /wrong result/) { my $L = length $@; print "# ===> Err($L): \"$@\"\n"; return 0 } push @$defs, '-DPERL__UUID__E2FS_INT'; push @$libs, '-luuid'; print "# ===> Found!\n";

My first (wrong) thought was that your system prototypes a couple of the parse/unparse functions a little differently. For instance: void uuid_unparse(const uuid_t uu, uuid_string_t out); Versus: void uuid_unparse(uuid_t uu, char *out); It's possible there's a buffer overflow there if your system expects more than a 37 char destination. It's not clear what uuid_string_t ultimately typedefs to. But, that doesn't make sense since test.pl passes... The "wrong result" is really coming from Devel::CheckLib in the block around line 330. Apparently the second system() call is failing, or at least not returning 0. That's where it tries to actually run the try_e2fs() test code. You might try something like this patch against CheckLib.pm: --- CheckLib.pm~ 2015-01-03 21:08:55.000000000 -0500 +++ /usr/lib/perl5/site_perl/5.20.1/Devel/CheckLib.pm 2015-08-16 06:55:11.457961878 -0400 @@ -327,7 +327,11 @@ push @missing, $lib if $rv != 0 || ! -x $exefile; my $absexefile = File::Spec->rel2abs($exefile); $absexefile = '"'.$absexefile.'"' if $absexefile =~ m/\s/; - push @wrongresult, $lib if $rv == 0 && -x $exefile && system($absexefile) != 0; + if ( $rv == 0 && -x $exefile ) { + my $runexe = system($absexefile); + warn "# system() returned $runexe\n" if $args{debug}; + push @wrongresult, $lib if $runexe != 0; + } unlink $ofile if -e $ofile; _cleanup_exe($exefile); } For bonus points you could add a die() too, just so you can run the leftover test program manually. I'd say it would dump core, but I wouldn't bet more than a half bucket of rusty bent nails on that. =)

Looks like a SIGSEGV. At least that's what signal 11 is here... Best guess is the additional uuid_string_t type on OS/X, so maybe this will solve the problem against Makefile.PL: --- Makefile.PL~ 2014-12-28 08:33:02.920933847 -0500 +++ Makefile.PL 2015-08-17 20:37:28.341680792 -0400 @@ -89,7 +89,7 @@ debug => 1, function => qq/ int i; - char s[37]; + uuid_string_t s; uuid_t u,uu; uuid_generate(u); uuid_generate_random(u); If not, well, I'd just be grasping at straws. You could also try deleting the uuid_*() calls one at a time in the try_e2fs() code, working from the bottom up until system() returns 0.

With that segfault still showing up this looks like an OSX problem, but it's really strange that test.pl passes with your earlier patch. Perhaps some strange interaction between Perl's system() call with scalar value and the shell? If you'll indulge me one last time though, maybe we can at least narrow down which sandbox to play in. Copy the following code block into testprog.c, then run: cc -luuid -o testprog testprog.c && ./testprog It should either segfault or print a cheery message. =) Show quoted text
---- begin code ---- #include <stdio.h> #include <uuid/uuid.h> int main(void) { int i; char s[37]; uuid_t u,uu; uuid_generate(u); uuid_generate_random(u); uuid_generate_time(u); uuid_unparse(u,s); uuid_unparse_lower(u,s); uuid_unparse_upper(u,s); uuid_parse(s,u); uuid_clear(u); uuid_copy(uu,u); i = uuid_compare(u,uu); i = uuid_is_null(u); printf("Success!\n"); return 0; } ---- end code ---- And by the way, thanks for the help. If it's not obvious, I don't have an OSX machine available so this is a little more than frustrating from my vantage point too.

zsh: segmentation fault ./testprog By applying comments and removing comments, I reduced the error to this line: i = uuid_compare(u,uu); With that line commented-out, I get the cheery message. I can also get it to run successfully with that line uncommented, but all of the uuid_unparse() lines commented: /* uuid_unparse(u,s); */ /* uuid_unparse_lower(u,s); */ /* uuid_unparse_upper(u,s); */ So it seems like it doesn’t like to compare UUIDs that have been unparsed.

Apple got back to me. They pointed out that if you omit the `-luuid` option, it works. This is because UUID is part of libc on OS X.

The problem is that get_struct_size() in Makefile.PL is returning 0. That sets the value for the define for PERL__UUID__STRUCT_SZ, which is used in UUID.xs to set the value returned by UUID_BUF_SZ(), which is used to size the string buffers in the various unparse functions. I can't figure out why get_struct_size() is failing, but I changed UUID.xs to use uuid_string_t and it compiles and the tests work now.

I can confirm that this patch fixes it for me, too. Though I couldn't get it to apply, so made the changes manually and generated a new patch, attached. Not sure how this would translate for a general solution, though.

Sorry about the patch. I copied-and-pasted when I should have attached. I think a general solution might be to use uuid_string_t, typedef-ing it to the current thing if it doesn't already exist. MacOS #defines _UUID_STRING_T. Of course, that assumes that uuid_string_t is always going to be implemented as a string by OSes, since it's being treated as such. The MacOS man page for uuid_unparse explicitly says "uuid_string_t (37-byte string including tailing '\0')", though. I'm not sure that the current sizing calculation really makes sense, to be honest: /* 2 hex digits per byte + 4 separators + 1 trailing null */ #define UUID_BUF_SZ() (2 * PERL__UUID__STRUCT_SZ + 4 + 1) PERL__UUID__STRUCT_SZ is sizeof(uuid_t). Why are we basing the size of the string representation on the size of an opaque binary representation? We're assuming that uuid_t is only ever going to contain the raw 128-bit value, but is that a valid assumption? In addition, is it ever going to be anything other than the space to hold a 36-character string?

Actually, it translates very well. The attached patch was done on FreeBSD, but it had a very similar problem -- the uuid code is within libc. I had to link explicitly with -lc instead of -luuid, so on the basis of the latest XS changes I'm assuming OSX needs the same thing.

Currently, Apple is the only vendor defining uuid_string_t. Everywhere else the prototypes are for either char* or char**. And my fear is that eventually others will start jumping on the uuid_string_t bandwagon also, and naturally all have their own way of doing it. So, worst case, I think we'd see the two existing unix interfaces turning into 4 or 8 as we deal with the variations. I think I like just leaving it the way it is since that uuid_string_t is ultimately just a char[37] anyway. Show quoted text

Honestly, I think the only reason that UUID_BUF_SZ is defined at all is because it bothered me having all the hardcoded 37's in the code. And since sizeof(uuid_t) is the only really universal constant, that's how it came to be calculated like that. It could easily be moved to Makefile.PL and passed as a variable instead, or just simply defined as 37.

This has been released to CPAN as version 0.24_02, along with a few other minor changes. So far there's been one successful install on OS X (0.24_01) so I'll wait to close this until we see more. Thanks to both of you though for pointing me in the right direction. And sorry for the long delay. I totally missed the update back in Oct.(?)

Yes, it's pretty bothersome that it links and runs as long as there aren't any uuid function calls. I've released 0.24_03 now which delays the link flag decision until later when it tries to run something more substantial. Since the build is possibly a lot more verbose though, I've also turned off all the debug parameters. To turn them back on... perl Makefile.PL DEBUG=1 Thanks!
