Describe the bug

Hello! I am filing this as one omnibus bug rather than submitting a PR or breaking it down into individual bugs because I'm not a developer on this project and it is a large and complicated process and I think if I try to do everything "in progress" I will make mistakes and will cause more harm than good. I hope that the folks who are developers on the project will be able to put this information to good use; if not then please feel free to simply close the bug, and I'm sorry for bothering you.

I attempted to use the kinetic AppImageLauncher deb on Debian Bookworm and it failed:

 appimagelauncher : Depends: libappimage0 (>= 0.1.6) but it is not installable

I decided to try building it from source by cloning it from the master branch here and following the build instructions, and I ran into a number of issues. I managed to work my way through them all and get it to build and install, so I wanted to share my work with you because I hope you will be able to use what I discovered to improve things for everyone.

I've appended below the exact script I ended up writing to get it to build. I describe each of the fixes I had to make in more detail in the following bullet points.

• The version of libappimage that you're cloning into the source tree and building is using a URL for boost that no longer exists. I replaced it with a different URL that does exist. This may not be the right fix; the right fix might be to use a newer version of libappimage that has already been fixed to use a different URL for boost. It might also be appropriate to upgrade to a newer version of boost (which you might want to do for another reason described below) which is downloadable from a different URL. All I'm doing here is pointing out the solution, not suggesting what I think the best solution is. ;-)

• As you can see in the script, I used apt build-dep appimagelauncher to get the build dependencies. I was able to do this because I installed the deb-src PPA repo. However, that didn't grab all of the necessary build-dependencies, and I had to install some separately with sudo apt install libssl-dev xxd qtdeclarative5-dev patchelf. I suppose the files used to build the deb package need to be updated to include these additional dependencies.

• The boost library version that you're using is incompatible with current glibc because PTHREAD_STACK_MIN is no longer a preprocessor symbol. This is fixed in newer boost versions, so the right fix here is probably to upgrade the build to use a newer version, but I didn't want to do anything that drastic so I made it build by making the small patch shown below.

• There are dependencies missing in the main AppImageLauncher build config, so make -j fails. I didn't bother to fix it; I just did the final build sequentially rather than in parallel. But it would be nice to flesh these out and fix them to make it possible to build faster.

I hope this is useful!

Sorry, one more thing... make install doesn't install libappimage.
