What at the original gtk+, for which the "gtk" flag was probably |
| 15 |
originally invented? |

There is a way to specify a GUI... |
| 33 |
|
| 34 |
[i3][waltdnes][~] grep "^\(X \|wayland \)" /usr/portage/profiles/use.desc |
| 35 |
X - Add support for X11 |
| 36 |
wayland - Enable dev-libs/wayland backend |
| 37 |
|
| 38 |
If overloading the meaning of USE="gtk" is the problem, the better |
| 39 |
solution would be to use "X" or "wayland" or whatever to indicate the |
| 40 |
GUI you need. "gtk" is a relic from the days of gtk+-1.x, when there |
| 41 |
were no other versions of gtk. With the advent of multiple versions, we |
| 42 |
arguably need "gtkn" useflags for every version in the tree, where "n" |
| 43 |
is the major version #. |
| 44 |
|
| 45 |
While we're at it, why are there 23 occurences of the "X" useflag in |
| 46 |
/usr/portage/profiles/use.local.desc when it exists in |
| 47 |
/usr/portage/profiles/use.desc ??? I'm talking about stuff like... |
| 48 |
|
| 49 |
app-misc/vifm:X - Add support for X11 |
| 50 |
dev-libs/m17n-lib:X - Builds the Graphical User Interface API and |
| 51 |
utilities for the package. |
| 52 |
dev-libs/wlc:X - Enable X11 backend and XWayland support. |
| 53 |
dev-python/PyQt4:X - Build bindings for the QtGui module |
| 54 |
dev-python/pyside:X - Build QtGui and QtTest modules |
| 55 |
