Emulator

Fair enough. I didn't realize it was considered unstable.

Thanks for the clarification.

Although... wouldn't it make more sense to consider this a low priority issue rather than closing it as invalid? Officially not supporting a dev branch is fine and makes perfect sense, but changes to this branch will be included in the next stable branch, which means Dolphin will fail to build with that as well. Seems like a better approach would be to keep track of known issues like this rather than ignoring them.

I run 2.8.10 myself, so honestly I'm not all that concerned right now if you rather leave this marked invalid, but after giving this a little more thought it didn't quite sit right with me. Just wanted to share my thoughts.

I'd love to help any way I can, but I'm not sure what you're asking for. Can you elaborate any? Sorry if this is something basic, I just don't deal with stuff on this level very often.

Thanks.

One of the ebuild contributers found that this works with wxgtk-2.9:
LDFLAGS="-lwx_gtk2u_aui-2.9 -lwx_gtk2u_adv-2.9 -lwx_gtk2u_core-2.9 -lwx_baseu-2.9" emerge -av dolphin-emu

I upgraded to 2.9 again to test myself and can confirm it will build/link properly. I've not done an exhaustive test, but dolphin seems to load and play games just fine with this option.

Are those LDFLAGS what you were referring to?

Are all of them needed?
isn't it enough to add the -lwx_gtk2u_aui-2.9 -lwx_baseu-2.9 ?

it seems that the new wx-config --libs got a bit different input
in 2.8 aui is included by default and in 2.9 only if you add wx-config --libs aui
it seems to add the aui libs.
Can someone confirm if that a feature or a gentoo bug?

I rebuilt using LDFLAGS="-lwx_gtk2u_aui-2.9 -lwx_baseu-2.9" as suggested and that does work fine. I tried again with just LDFLAGS="-lwx_gtk2u_aui-2.9" and that also works, so as you suggested in your last comment, the missing aui seems to be the problem.

On Gentoo I see the behavior you describe regarding --libs and aui. The only other system I have available with semi-easy access to wxGTK 2.9 is an Arch system. I'm currently building wxGTK on it and will let you know what it reports for --libs to compare against Gentoo.

Whew, that took its sweet time. :-) I see the same behavior regarding aui on both Gentoo and Arch. For reference, here's what I see on both systems:

arch-2.9 $ wx-config-2.9 --libs
-pthread -lwx_gtk2u_xrc-2.9 -lwx_gtk2u_html-2.9 -lwx_gtk2u_qa-2.9 -lwx_gtk2u_adv-2.9 -lwx_gtk2u_core-2.9 -lwx_baseu_xml-2.9 -lwx_baseu_net-2.9 -lwx_baseu-2.9

arch-2.8 $ wx-config --libs | grep -i aui
-pthread -Wl,--hash-style=gnu -Wl,--as-needed -lwx_gtk2u_richtext-2.8 -lwx_gtk2u_aui-2.8 -lwx_gtk2u_xrc-2.8 -lwx_gtk2u_qa-2.8 -lwx_gtk2u_html-2.8 -lwx_gtk2u_adv-2.8 -lwx_gtk2u_core-2.8 -lwx_baseu_xml-2.8 -lwx_baseu_net-2.8 -lwx_baseu-2.8

gentoo-2.9 $ wx-config --libs
-L/usr/lib64 -pthread -lwx_gtk2u_xrc-2.9 -lwx_gtk2u_html-2.9 -lwx_gtk2u_qa-2.9 -lwx_gtk2u_adv-2.9 -lwx_gtk2u_core-2.9 -lwx_baseu_xml-2.9 -lwx_baseu_net-2.9 -lwx_baseu-2.9

gentoo-2.8 $ wx-config --libs
-L/usr/lib64 -pthread -Wl,-O1 -Wl,--as-needed -L/usr/lib64 -lwx_gtk2u_richtext-2.8 -lwx_gtk2u_aui-2.8 -lwx_gtk2u_xrc-2.8 -lwx_gtk2u_qa-2.8 -lwx_gtk2u_html-2.8 -lwx_gtk2u_adv-2.8 -lwx_gtk2u_core-2.8 -lwx_baseu_xml-2.8 -lwx_baseu_net-2.8 -lwx_baseu-2.8

I guess the wx probing in the cmake should be changed to something like
FIND_PACKAGE(wxWidgets COMPONENTS base core aui)
Glen: What do you think?

nakeee: Yeah, this sounds right.
nitro322: Sorry. I should have marked this as low priority as you said.

Sometime I will have to install 2.9.1 to see what I can do.

2.9.1 works fine on OS X, though I am using the 2.9.2 trunk for some rather minor bug fixes. 2.9.0 was a bit of a disaster, but there has been much progress since then.

At some point I would like to upgrade Externals/wxWidgets so that the OS X build has no third party dependencies, but I am not sure if the right time is going to be 2.9.2 or 3.0 or what.

This won't affect Linux much, since a shared library is usually used there, but it would be useful if someone on Windows could do some testing with 2.9.[12].

Later revisions should link agains 2.9.1 now on linux. I get segmentation faults when trying to run it, but it compiles and links.

Perhaps this should be merged with http://code.google.com/p/dolphin-emu/issues/detail?id=4535&q=wxWidgets
