How to build on Alpine Linux

[bestpika]

I tried to compile DosBox-X on Alpine Linux by referring to the AUR on Arch Linux.
But I found a lot of problems with the compilation process. I would like to ask what packages should be installed to compile and package DOSBox-X on Alpine Linux.

You certainly don't need physfs. Dosbox-X is not linked to this external library in any case.

It all depends on what you need. A lot of dependencies are optional. You want screenshots - you will need libpng, you want to be able to record video in mpegts format with x264 codec, you need ffmpeg. Etc.

You have to be much more specific.

It would be nice if there was a list of libraries that I could select by function, but I don't seem to see such a list.

[grapeli]

Such a list exists for ubuntu, fedora.

It will be different for each of the Linux distributions.
It will be different depending on whether you will be building on SDL1 or SDL2.

@grapeli
Thank you so much, it is hidden here.
I'll try to check the Alpine Linux package list to see if there is a library for it.

[grapeli]

These are the standard libraries available in every distribution. Of course, they usually have different names, they can have different versions, they are sometimes packed differently (more fragmented).

Okay. I've done it.

prepare() {
  default_prepare
  sed -i "s/sys\/perm.h/sys\/io.h/i" "$builddir/src/libs/porttalk/porttalk.cpp"
}

build() {

  # SDL2
  # ./build-debug-sdl2
}

package() {
  make DESTDIR="$pkgdir" install
}

Fast progress.
A few cosmetic fixes. You certainly don't need sdl-dev. Even if you would build on the basis of SDL1, it is rather only with the attached library.
Likewise, nasm is redundant. Even up to SDL1. For example, in Archlinux.

As of Alpine Linux 3.19, musl libc no longer contains separate fopen64(), fseeko64(), or ftello64() functions, which causes the build to fail. On modern libcs, there is no need for separate lfs64 functions because the normal functions are already 64-bit.

configure already outputs checking for gcc option to enable large file support... none needed. So I'm not really sure why these functions are still being used here.
