Description Nerijus Baliūnas 2007-11-20 22:30:30 UTC

Why --enable-compat24 is used? Does any depending application need it?

BTW, if you decide not to use it, you'll need to recompile all applications,
otherwise you'll get:

$ codeblocks 
Fatal Error: Mismatch between the program and library build versions detected.
The library used 2.8 (no debug,Unicode,compiler with C++ ABI 1002,wx
containers,compatible with 2.6),
and your program used 2.8 (no debug,Unicode,compiler with C++ ABI 1002,wx
containers,compatible with 2.4,compatible with 2.6).

Is there a downside of enabling it? I can turn it off, but it seemed good to have.

Comment 2 Nerijus Baliūnas 2008-02-20 21:31:18 UTC

wx by default enables compatibility with one past version only (2.6 in this
case),  and imho it's enough. When applications are ported to a higher wx
version, they usually are made to work with wx compiled with default settings
(by just running ./configure), so enabling more compatibility is useless and
only makes library bigger (unless there are apps which do not work without
--enable-compat24, but I don't know any). Anyway, it's a minor issue.

Comment 3 Matthew Miller 2008-02-20 21:37:54 UTC

I think retaining compatibility for two versions is valuable enough that I'm
inclined to keep it on. How much space/memory is saved by not enabling it?
