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:

 prepare() {
        unzip -o ${pkgname}-v${pkgver}.zip
 }

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

 package() {
-       cd "${srcdir}/${pkgname}"
+       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.

@alex.henrie Are you sure dependencies are not missing anything? The official docs https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/linux-macos-setup.html list other dependencies.
