Readme is not clear enough

[socketpair]

I'm newbie in cross-compiling for macos.

https://github.com/tpoechtrager/osxcross?tab=readme-ov-file#installation says:

Place your packaged SDK in the tarballs/ directory.

So, what IS SDK ? I mean what form it should look like ? A dir, files ? archive ? .dmg ? what ?

okay, going deeper to the link:

From Xcode Command Line Tools

1. Download Command Line Tools as described above
2. Install: clang, make, libssl-devel, lzma-devel, and libxml2-devel
3. Run: ./tools/gen_sdk_package_tools_dmg.sh <command_line_tools_for_xcode>.dmg
4. Move the SDK to the tarballs/ directory

(1), (2), (3) - all done.
(4) How to do it ? What should I move ?

Please fix the doc, or tell me the answers, and I will.

"Apple SDK", just type that into google
, send you to https://developer.apple.com/ , and SDK is at the bottom. Is that so hard to find?

[socketpair]

Very hard. I still can not. Every time you google it, everyone explain what is SDK in general. But no one explains what files they mean.
I have downloaded command line tools .dmg. Run tools/gen_sdk_package_tools_dmg.sh. But what it does exactly ? Generate what? Where ?

Sorry for stupid questions, but I really don't understand. I'm not joking. Just don't have any experience in specific Apple development.

https://developer.apple.com/download

Okay, and ?

But I already downloaded these command line tools. And gave this file to the script mentioned in doc. I.e. point 1,2 and 3. How to do step 4 (from the first message)?

4. Move the SDK to the tarballs/ directory

What IS the sdk ?

[socketpair]

@HinTak I found. In "in MacOS" section it is described. In "on Linux" is not. So answer is simple: SDK is single *.tar.* file that appears after running script.

Very simple, but is not obvious. Since I work on Linux, I just skipped MacOS section .

1. Download Xcode as described above --> Xcode image needed for SDK creation
2. Install: clang, make, libssl-devel, lzma-devel, and libxml2-devel --> Dependencies
3. Run: ./tools/gen_sdk_package_pbzx.sh .xip --> Generates the SDK & even lists the generated SDKs
4. Move the SDK to the tarballs/ directory --> Move the generated SDK(s) into the tarballs directory

What exactly is unclear? I mean, I could add another step explicitly mentioning that the MacOSXXX.tar.* files should be moved, but that should be obvious. Some basic knowledge is expected when working with a toolchain like this. ;)

[socketpair]

@tpoechtrager only step 4. For me it was not obvious at all. Again, in "on MacOS" section it is described. In "on Linux" is not. Since I came to the project to crosscompile, I did not even read MacOS section.

And I obviously have zero knowledge with these toolchain. And the more interesting, that I asked AI and google, and did not get answer. Only general things like "what is sdk"
