* GNUInstallDirs is the only Kitware-supported
way to change the default directories. Most
distributions have hooks for changing these
directories, which makes integrating wesnoth
easier and more consistent with the rest of
the CMake ecosystem.
* Make build system perfectly out-of-source
compatible. The build system should never
touch files in the source tree.
work around the symptom of issue #1741https://github.com/wesnoth/wesnoth/issues/1741
This is only a workaround and needs to be handled by the one doing the
next pot-update somehow. Maybe something needs to be changed in the
scons recipe if this was used for the last pot-update?
This is intended to be used instead of the Game Version dialog's
clipboard text report in the event that Wesnoth cannot reach the
titlescreen or the dialog for some reason.
Unlike the --version info dump, it performs various calls to the
filesystem API which have potential side-effects on the environment
(namely, creating a user data directory structure if none existed before
running the command). It seems highly improper for a program's --version
switch to perform any actions other than printing text to its parent
terminal, hence I thought it would be better to add a new switch with a
more active phrasing, also reflected in its accompanying documentation.
Ultimately, this and its UI counterpart should be used by 1.14 players
as part of the bug reporting process, preferably as a mandatory step
before submitting new reports on GH or the forums.
This does several things:
- Make the formatting consistent, using underline instead of <angle brackets> for all arguments
- Add many missing switches; some experimental/dev ones are still not listed though
- Ensure all switches are listed in alphabetical order
- Fix some inaccurate details
- Minor fixes to the output of --help
In addition, the following additional switches now force a console on Windows:
--nogui
--logdomains
--path
--render-image
--screenshot
--data-path
--userdata-path
--userconfig-path
--version
Cross-compiling to Windows with MXE [1] requires providing custom
CMAKE_MODULE_PATH variable for CMake:
$ cmake -DCMAKE_MODULE_PATH=/file/provided/by/mxe.cmake
As Wesnoth's CMakeLists.txt resets CMAKE_MODULE_PATH, the effect of
CMAKE_MODULE_PATH provided by MXE is disabled and the build fails
with linking errors [2].
This commit changes CMakeLists.txt to respect the value of
user provided CMAKE_MODULE_PATH, so both MXE and Wesnoth
customizations of CMake variables are applied.
