wx-config symlink with wxGTK 2.4 AND 2.6

Message

This one has been puzzling me today: I had wxGTK 2.4 already installed, and went to install 2.6 too. Once emerged, I discovered that I couldn't compile applications that required the very same wxGTK 2.6 that I had just installed (one of these was the Catapult frontend from http://openmsx.sourceforge.net/, which is not in portage).

After some research, I discovered that the problem was that the symlink wx-config was still pointing to the 2.4 config script, and that the one for 2.6 was called wx-config-2.6. OK, I could change the symlink making it point to wx-config-2.6, but this seemed a bit hackish for me; actually I thought that something was wrong in the ebuilds.

So I downloaded both source tarballs for wxGTK 2.4 and 2.6, and compiled them in order in my home directory, making them "overlap" on purpose. At the end of this process, it turns out that wx-config is pointing to 2.6 script (as I expected).

Unemerging both 2.4 and 2.6 and reemerging only 2.6 makes wx-config pointing to 2.6 script too (obviously, since there is no 2.4 installed).

Could this be a bug in the ebuild, or somewhere on gentoo's side? Moreover, am I the only one suffering of this problem?

Pass --with-wx-config=wx-config-2.6 --with-wx-config-path=/usr/bin to configure -- or see how e.g. the vlc ebuild does it.

btw: portage does not tolerate overlaps between packages, which is why the 2.6 wx-config is renamed.

As for vlc, I have trouble now with 0.8.4-r1 ebuild.

Code: Select all

# emerge -upv media-video/vlc

These are the packages that I would merge, in order:

As you can see, I have installed two versions of wxGTK.

Code: Select all

# emerge -Cp x11-libs/wxGTK

>>> These are the packages that I would unmerge:

 x11-libs/wxGTK
    selected: 2.4.2-r3 2.6.2-r1
   protected: none
     omitted: none

The relevant parts inside the ebuild are...

Code: Select all

pkg_setup() {
    if use wxwindows; then
        WX_GTK_VER="2.6"
        need-wxwidgets unicode || die "You need to install wxGTK with unicode support."
    fi

and....

Code: Select all

src_compile () {
    use nsplugin && myconf="${myconf} --with-mozilla-sdk-path=/usr/$(get_libdir)/gecko-sdk"

Yes, but then it says:

!!! $FUNCNAME: /usr/lib/wx/config/gtk2-unicode-release-2.6 not found
!!! $FUNCNAME: /usr/lib/wx/config/gtk2-unicoded-release-2.6 not found
!!! You need to emerge wxGTK with unicode in your USE

(or it should, anyway). Emerge wxGTK-2.6 with unicode in USE and try again.

ecatmur · Post by **ecatmur** » Mon Dec 12, 2005 11:19 am

btw, when you're writing your ebuild you may or may not need unicode; if not use need-wxwidgets gtk2 rather than need-wxwidgets unicode.

ecatmur · Post by **ecatmur** » Mon Dec 12, 2005 11:21 am

Or, if it really doesn't matter, set WX_CONFIG=/usr/bin/wx-config-2.6 and it will use whatever is installed.

I tried reemerge wxGTK with unicode useflag for the first time after that.
That fixed the problem! (mixing 2.4 and 2.6 versions do not seem to trouble to me.)
Thanks!
