@TheAceBlock I see, thank you.

@dimich This is likely the source of the zip file update: https://github.com/espressif/esp-idf/issues/15697#issuecomment-2769105465

Does anyone know what was changed in release archive? Such changes look suspicious for me after the incident with xz.

Looks like the release zip file for the 5.4.1 release was recently updated, and the checksum changed.

It's now d78e49aafe46e35d34bc8804b64f23cd0a6cabdfe221876ba59f68b4534f0839.

In addition, the folder extracted from the zip now has the version in the path, requiring a small change to both cd ... lines.

Here's my patch to get it working:

        unzip -o ${pkgname}-v${pkgver}.zip
 }

 build() {
-       cd "$srcdir/${pkgname}"
+       cd "$srcdir/${pkgname}-v${pkgver}"
        git submodule update --init
 }

 package() {

+       cd "$srcdir/${pkgname}-v${pkgver}"
        mkdir -p ${pkgdir}/opt/esp-idf
        cp -R . ${pkgdir}/opt/esp-idf
 }

I'm getting an error running the install script:

ERROR: tool openocd-esp32 is found in PATH, but has failed: non-zero exit code (127) with message: openocd: error while loading shared libraries: libcapstone.so.4: cannot open shared object file: No such file or directory

The script exits fine afterwards.

Looks like there's a dependency on capstone=4?

Hum, now I'm seeing a lot of

fatal: not a git repository (or any of the parent directories): .git
fatal: not a git repository (or any of the parent directories): .git

when building projects, so maybe we can't get away with dropping the .git directory.

... ah, but that won't work because it does a git submodule update in the build step.

We need to remove the .git directories after that. This can be done with

find . -path \*/.git/\* -delete -o -name .git -delete

That will remove the .git directory from the submodules, too.

So, this:

build() {
    cd "$srcdir/${pkgname}-v${pkgver}"
    git submodule update --init
    find . -path \*/.git/\* -delete -o -name .git -delete
}

Which gives us a ~80MiB package, at around 450MiB when installed.

FWIW, you can skip extracting the .git directory altogether by adding the following at the end of the unzip command the prepare function:

... -x \*/.git/\*

So:

prepare() {
    unzip -o ${pkgname}-v${pkgver}.zip -x \*/.git/\*
}

Am I talking to myself or what

Is the .git folder needed for anything? It takes up a gigabyte.
