Re: compiling on linux

"-lz" should do it.

Well, ./configure -lz doesn't work, make -lz works but doesn't help

Until now I use following steps:

./configure --enable-zipstream --enable-fs_zip --disable-monolithic
--with-zlib --prefix=/opt/wx/2.6/
make & make install

Since the library names differ on various platforms and configs, the
easiest way is to use `wx-config --libs`. It will give you the linker
line matching whatever config you used when building wx.

What exactly is the error message you get when linking your program using
wx-config?

Also note that wxzlib isn't included in the libs returned by `wx-config
--libs` when using dynamic linking since apps don't usually use it
directly.

You can get it using '--libs zlib' but AFAIK in that case you need to
specify all the other libs you need too. e.g `wx-config --libs xrc qa
html adv core xml net zlib`.

HTH,

Oops I've got that wrong actually, before you waste time trying it out.

Of course, the library isn't called wxzlibd.lib, I think, it could be namend

libwxzlib.so. But this file (or a file which is called nearly like this) cannot

be found. wx-config doesn't either show a file called '*zlib*'. I'm still

searching.

Well, "--libs zlib" returns, that I should use "-lwx_gtk2u_zlib-2.6". So we know
that the lib is called libwx_gtk2u_zlib-2.6.so. But this file is not in the
lib-directory of wxWidgets. Where can I find it?

I have configured the library with './configure --enable-zipstream
--enable-fs_zip --with-zlib --enable-shared --prefix=/opt/wx/2.6'

Hi,

I'm afraid I got that wrong, "--libs zlib" doesn't return the right
name.

Most linux machines will have zlib installed already, so wxWidget's
configure will detect that and use it instead of the built in one. So,
in that case adding '-lz' to your application's link line should work
(as Matthias said).

I don't think there's anything you could do to be more general, i.e. to
detect when the built-in has been used and link to that one instead.
