Make libsdl3 NOT use Wayland #9726

I would like to be able to debug this, but, even with 40+ years in IT working on platforms many here have never heard of, I can't for the life of me figure out where to park a modified copy of this file Can someone please post a link with instructions on where to place an xmake.lua file for a package dependency so that xmake uses that one instead of the on it has in git? In the meantime I'm watching the world's slowest download of Debian 13 Mate so I can spin up that vm and and see if XMake has the same problem as VCPKG . . . only works with the distro that shipped 5 minutes ago. This could also just be MX Linux specific. Need to know that. |

Sorry, I haven't had much time to analyze it lately. You can create your own private repository to modify and debug libsdl3. https://xmake.io/guide/package-management/distribute-private-libraries.html#repository-management Of course, if you only need to debug the package configuration in the official repository, you can simply clone the xmake-repo source code and then run the script below to quickly test and verify the libsdl3 package configuration and installation. git clone ... xmake-repo
cd xmake-repo
-- edit libsdl3 xmake.lua
xmake l scripts/test.lua --shallow -vD libsdl3see https://github.com/xmake-io/xmake-repo?tab=readme-ov-file#test-a-package-in-local |
These configurations only cause xmake to attempt to find an existing Wayland package on the system, but they don't trigger an installation. However, according to the initial logs, the Wayland package was also installed. The system's Wayland package wasn't found. |

When I get to the office later this morning I will upload some logs. Starlink was taking a dump yesterday so could not upload. I set up a clean Ubuntu 24.04.5 VM. Made sure build-essential and curl were installed along with Guest Additions and a couple of editors. Build failed. Dependencies are really off. The CMake scripts couldn't find Alsa and a bunch of other stuff. They didn't fatal out, they just complained and kept going so I gotta believe the "test" doesn't actually test anything. I think the real problem is these builds aren't being tested in a sterile environment. I have no idea why, when building on MX Linux, it couldn't find the OS install expat.h Why is it xmake cannot find system packages on Linux? I would think that fundamental capability would have been the first thing developed. I'm not a LUA programmer, just C/C++ mostly these days. In your XMake world you are doing something like this are you? If you define the variables like they did, you override the system search paths. When tweaking environment variables one has to do it like this:
You can either append or prefix, but you must include the previous value too. Doing this
walks on the system include paths. I like the examples found here. They provide a more verbose C++ one as well Need to find a way to wedge both of those into the xmake universe of the build because I suspect the system search paths got walked on by an environment variable setting. On a clean Ubuntu 24.04.5 VM the building of libsdl3 most certainly does not work. It should be able to work in an empty VM that has nothing more than build-essentials and curl installed. I know the xmake build is missing both the Alsa and XML dependencies, will skim through the logs for others. The missing XML is fatal error due to missing header file. When Alsa is missing it appears the support is simply not built. Here is a fundamental question. Should xmake even be looking for system installed packages? In this thread I posted the manifest generated for SDL3 by xmake. It builds static. System installed libraries will most likely be dynamic. This is a complication for Debian/RPM/whatever packaging and distribution. Just thinking out loud here. Right now I don't know how the SDL3 package ever built. It failed the clean VM test. So, we have multiple problems.

I'm terribly sorry, life got in the way today and Starlink was being its usual unreliable self. Both files are here. Since the redirected log was large it was zipped. Some interesting things from the screen scrape From the log the following dependencies are either not part of the package or get pulled in at the wrong time. 2 | #include <zlib.h> 51 | #include <expat.h> Ah, here is the issue with expat. You don't have libexpat1-dev in your repos and you don't fail. I have no clue was to why wayland is being requested since I used the configuration options of no wayland, but, libwayland-dev isn't in your repos and it fails without aborting the job. Whatever you are using for vcpkg lookup is incorrect. Same with wayland I don't know how to read your logs. Around line 10312 you actually compile expat stuff I hope this helps. |

I tried it on linux. I don't see Wayland being installed; it has been disabled. It works for me. add_rules("mode.debug", "mode.release")
add_requires("libsdl3", {configs = {wayland = false}})
target("test")
set_kind("binary")
add_files("src/*.cpp")
add_packages("libsdl3")ruki@0865ad527ff9:/tmp/test$ xmake f -c

I don't know what you're trying to say. In the limited xmake.lua configuration you provided, I only saw the If the library you are compiling is an xmake target, then it is completely independent of testing the installation of libsdl3 and has nothing to do with it. Even if I change If you want a more accurate description of your environment, please provide a complete, minimal, reproducible project and its configuration. I don't have much time to guess and set up your environment. You can directly upload the complete project zip as an attachment to the issues. Or provide your Docker file or image. |
|
No guessing or zip required git clone https://roland_hughes@git.code.sf.net/p/basisdoctrina/code basisdoctrina-code switch to the xmake branch ./build-BasisDoctrina-local.sh I've tracked down most of the missing dependencies for libsdl3 in the xmake.lua you will find there. Commenting out of these two (for now) got around wayland (for now) One of them must be pulling it in. The building of sdl3 /x11 still has issues. |

Sorry Xmake 
|
|
I'm working around the issue now. Documentation was unclear with add_deps() vs. add_packages() to add dependencies. add_deps() of something in the repo, whether intended or not, forces a build. Please wait until morning unless you are looking to track that down. |

Okay, I did fresh push, I'm punting for evening. Man, Yocto builds for medical devices are easier than this. |
If you do not modify XMAKE_PKG_CACHEDIR, XMAKE_PKG_INSTALLDIR, glib still works for me. ruki@0865ad527ff9:/tmp/basisdoctrina-code$ ./build-BasisDoctrina-local.sh

The documentation says I can set those variables to stop the large scale pollution of my project tree. Glib and a few others appear to not work if you set those. They ASS-U-ME they are allowed to pollute the project source tree. This is indeed a bug. Polluting the project tree with build artifacts is never ever good. Bad design really. |

libsdl3 was still installed successfully, and no Wayland issues were found. I don't know what you changed, but I couldn't reproduce the problem. ruki@0865ad527ff9:/tmp/basisdoctrina-code$ ./build-BasisDoctrina-local.sh

What I changed was commenting out the other two SDL3 modules (that was the wayland bug which still needs to be resolved). Other build issues were tied up with add_deps() add_package() issues. Oh, and the fact glibmm isn't in the repos |
Uh oh!
There was an error while loading. Please reload this page.
I'm building a branch of the fledgling BasisDoctrina project, converting to XMake. Dev system is MX Linux VM to deliberately avoid all things Wayland.
Documentation for libsdl3 says all I should have to turn off is wayland_shared. Reading the .lua file on that page it appears there is also a wayland variable that is not documented as needing to be set.
In my xmake.lua I have the following:
When I run the build shell script I see
Then it dies here.
There is nothing more "verbose" at the end of that log.
I Ass-U-Me the expat. h error is somehow related to the Wayland issue. If not, does not matter, I will shoot that bug later. Main focus now is properly killing Wayland. I'm running X11 here.
The master branch uses CMake and builds fine.
So, my question is, what is missing from the libsdl3 documentation with respect to completely putting two behind Wayland's ear and leaving it in the woods?
