the wxGTK problem thread

[RlC]

hi,

most troubles in passed days i have had with wxGTK. there are several programs (amule, audacity) that actually won´t work for me. i get errors that say prototypes wouldnt match, and i know this is due the versions of wxgtk.

for example, i want to compile the beta of audacity (acutally 1.3.0), and i have installed both 2.4 and 2.6 of wxgtk. i think there are problems for configure with getting the right path of the header files, and i couldn´t find a way to avoid this. once there are apps that need 2.4, then there apps that need 2.6. is there a suitable workaround for getting both kind of programs to work?

this is probably the most annoying thing since i use gentoo (ok, i didnt really use other distros)

and just another question:
windows users can install amule/audacity, they get usually binaries
do they need headers? in the meaning of: if i would install a precompiled package (eg from debian), would they work (or at least should they work)?

at the time i am running amule, but not audacity (not even the stable one in portage [1.2.1])

i guess/hope i am not the only one with problems on wxGTK, so i hope there will be some help
thanks

could you try changing the 2.4-ebuild to:

Code: Select all

src_compile() {
	local myconf
	export LANG='C'
	filter-flags -fvisibility-inlines-hidden
	myconf="${myconf} `use_with opengl`"
	myconf="${myconf} --with-gtk"
	myconf="${myconf} `use_enable debug`"
	myconf="${myconf} --libdir=/usr/$(get_libdir)"
	myconf="${myconf} --enable-soname"

i mean adding the last line to src_compile and test if this could help you, I don't use 2.4 anymore, but this could be your problem. As if you mix the both and 2.4 libraries do not get versioned as currently is the case, this could lead to problems in the resolution.

I assume you are in x86, in which case the solution for audacity is to unmask the ebuilds from portage, so you get wxGTK 2.4.2-r4 (or later), and wxGTK-2.6.2 or later, which are slotted. You can then put audacity-1.2.4b-r1 or audacity-1.3.0b on top without problems.

The trick is that you can tell the configure script for the application which wx version to use by changing which wx-config binary get's run during configure. These live in either /usr/bin (for 2.4) or /usr/lib/wx/config/ (for 2.6). Simply find the right binary, and set the WX_CONFIG environment variable to point to it (at compile time).

ebuilds have an eclass to do this stuff for them.
