See, normally the order doesn't matter but in this case it obviously does. So noted. So I change the order, this time TwinTree.xs shows some improvement although I still can't see any actual XSUB code: `#include "EXTERN.h" #include "perl.h" #include "XSUB.h" #include "ppport.h" #include <libtwintree.h> #include "const-c.inc" MODULE = TwinTree PACKAGE = TwinTree INCLUDE: const-xs.inc int return_one() int return_zero()` [download] Declarations are a good place to start, but the definitions are still missing. When trying 'make test' on the module, this is what I get: PERL_DL_NONLAZY=1 /usr/bin/perl "-MExtUtils::Command::MM" "-e" "test_h +arness(0, 'blib/lib', 'bl +ib/arch')" t/.t t/TwinTree....NOK 1 # Failed test 'use TwinTree;' # at t/TwinTree.t line 9. # Tried to use 'TwinTree'. # Error: Can't load '/home/floyd/twintree/TwinTree/blib/arch/auto +/TwinTree/ TwinTree.so' fo +r module TwinTree: /home/floyd/twintree/TwinTree/blib/arch/auto/T + winTree/TwinTree.so: undefine +d symbol: return_one at /usr/lib/perl5/5.8.8/i386-l + inux-thread-multi/DynaLoader.pm line 230. # at (eval 4) line 2 # Compilation failed in require at (eval 4) line 2. # BEGIN failed--compilation aborted at (eval 4) line 2. # Looks like you failed 1 test of 1. t/TwinTree....dubious Test returned status 1 (wstat 256, 0x100) DIED.

although I still can't see any actual XSUB code No, what you have there is sufficient. `... int return_one() int return_zero()` [download] What you posted later is overkill. `... int return_one() CODE: RETVAL = return_one(); OUTPUT: RETVAL int return_zero() CODE: RETVAL = return_one(); OUTPUT: RETVAL` [download]	[reply] [d/l] [select]

Declarations are a good place to start, but the definitions are still missing. I'm sorry, what? When trying 'make test' on the module, this is what I get How did you compile libtwintree? Does it export symbols return_one return_zero? Is libtwintree.so in path? What does `ldd /blib/arch/auto/TwinTree/TwinTree.so` return?	[reply] [d/l]

All my compile switches are in the Makefile, as are the commands for installing the .so into /usr/local/lib As for `ldd blib/arch/auto/TwinTree/TwinTree.so` it says `libc.so.6 => /lib/libc.so.6 (0xb7f24000) /lib/ld-linux.so.2 (0x0071d000)` [download] -- Time flies when you don't know what you're doing	[reply] [d/l] [select]
