Re: POI-Ruby
did you try ldd on poi4r.so? or put libgcj in LD_LIBRARY_PATH? Also, the version of Swig i used was, i believe, 1.3.27.

Re: POI-Ruby
Please forgive my inexperience. I added libgcj to LD_LIBRARY_PATH and it now will run properly but segfaults. I'm working on figuring out exactly where the segfault occurs. At this point I know it's during JvCreateJavaVM(). Thanks again. Avik Sengupta wrote: did you try ldd on poi4r.so? or put libgcj in LD_LIBRARY_PATH?

POI-ruby - ruby hangs
I'm able to create xls files with poi4r just fine but for some reason
any ruby script that requires poi4r hangs at the end. Has anyone ever
experienced this? Or possibly have some ideas as to what causes it.
b.rb:
require 'release/poi4r'
puts 'test'
strace ruby b.rb:
...
write(1, test\n, 5test
) = 5
rt_sigaction(SIGINT, {SIG_DFL}, {0x80a1f1c, [], SA_RESTORER|SA_RESTART,
0x400994f8}, 8) = 0
write(5, \240\20\271A\2\0\0\0\0\0\0\0\4\317\6\0\220\357\377\277...,
148) = 148
rt_sigprocmask(SIG_SETMASK, NULL, [CHLD RTMIN], 8) = 0
rt_sigsuspend([CHLD] unfinished ...
--- SIGRTMIN (Unknown signal 32) @ 0 (0) ---
... rt_sigsuspend resumed ) = -1 EINTR (Interrupted system call)
sigreturn() = ? (mask now [CHLD RTMIN])
wait4(5842, NULL, __WCLONE, NULL) = 5842
write(5, \240\20\271A\7\0\0\0\260\277\270A`\356\377\277\300q\32...,
148) = 148
rt_sigprocmask(SIG_SETMASK, NULL, [CHLD RTMIN], 8) = 0
rt_sigsuspend([CHLD]
Thanks,
Jeff
Incidentally, one test fails (although I don't think this is related):
1) Failure:
test_base(TC_base_tests) [./tests/tc_base_tests.rb:70]:
hour.
15 expected but was
19.
3 tests, 10 assertions, 1 failures, 0 errors

Re: POI-Ruby
Jeff You can certainly wrap stuff on your own, but I would figure it will be a lot of work, which is reason I started on swig. I wouldnt start on it unless you either have a lot of time, or some significant experience writing C extensions for ruby (neither of which is true for me) You'l have to declare the function signatures to call from ruby, convert objects (eg ruby strings to gcj string objects) and handle memory allocation and de-allocation on either side. Both ruby and java being garbage collected, not only will you have to worry about leaks, but also premature collection. http://www.rubycentral.com/book/ext_ruby.html has the basics. You've probably already seen this. With swig, you still have to worry about all this, but a lot of the boilerplate is generated. For eg, you'll have to write the object wrapping code once, and not worry about calling it every time an object is referenced. As for segfaults, the whole thing, i've found, is quite sensitive to swig version. Maybe you can try with an older swig version? Regards - Avik On Thursday 22 Mar 2007 3:03:11 am Andrew C.

Re: POI-Ruby
Thanks for the responses. Avik, What version of SWIG has worked the best for you? The version installed here is 1.1 (patch 5). I see that is the most recent stable release.
