Are sub-versions now binary-compatible?

Ruby
1

I found I had to build separate versions of a binary library to run on
1.8.2 and 1.8.4

Do versions 1.8.4 and 1.8.5 also have binary incompatibilities? Is
there a test suite
around i could use?

Thanks,
Eric

Which library?

Depends on the library. Some can be used cross version, others can’t.

ParseTree refuses to work on a library other than the one it was
built on. I’ve had no luck running ImageMagick on multiple ruby
versions either.

Well, you might do a diff on any included files.

diff ruby1.8.4/ruby.h ruby1.8.5/ruby.h shows that there ARE
differences, which would indicate to me that it’s probably not wise to
count on binary compatibility.

i always recompile all extensions when an upgrade comes out. i’ve had
issues
in the past when i didn’t.
