protobuf-compiler not including the protobuf compiler (in sdk)

[DAdolfsson]

Hi,
I recently attempted to assemble a sdk for one of my colleagues but we had problems.

The SDK was successfully built but no protoc compiler was included.
From what i can tell it was not included in the nativesdk-protobuf-compiler package.

I am far from an expert in this, and lots of the recipe goes above my head.
But, to resolve my issues i changed a single line that looked wrong in the recipe:

diff --git a/meta-oe/recipes-devtools/protobuf/protobuf_3.21.5.bb b/meta-oe/recipes-devtools/protobuf/protobuf_3.21.5.bb
index 0bc9cbedc..e7486857f 100644
--- a/meta-oe/recipes-devtools/protobuf/protobuf_3.21.5.bb

+PACKAGECONFIG[compiler] = "-Dprotobuf_BUILD_PROTOC_BINARIES=ON"
 
 EXTRA_OECMAKE += "\
     -Dprotobuf_BUILD_SHARED_LIBS=ON \

From my understanding of the precompiler, by adding the same variable twice with different values it will only respect the last one.

Best Regards

Can you test this patch instead ? and report back if it works

Thank you,

I it appears to have solved the issue for the generated SDK!

I did a clean-all on the proto* packages and the image.. Verified that the package files was gone and rebuilt..

Now the protoc compiler is present

Ah.. just saw that you already included it in master.

Thank you!
