Protocol buffers are a language-agnostic method for serializing structured data that can be used as an alternative to XML or JSON in your iOS apps. * * * This is a companion discussion topic for the original entry at [https://www.raywenderlich.com/749-introduction-to-protocol-buffers-on-ios](https://www.raywenderlich.com/749-introduction-to-protocol-buffers-on-ios) ---

Could be more interesting with a full stack Swift solution 😉 Another solution is to use [flatbuffer](https://google.github.io/flatbuffers/index.html) ---

@frohmen yes haha it’s suppose to spit out all of that. I couldn’t find a way to not make the script verbose. sorry 😕 @tof yea could be cool! ---

I’m getting this error while running ./protoInstallation.sh : `libtool: link: cannot find the library Buffers/Starter/protobuf-3.1.0/src/libprotobuf.la or unhandled argument Buffers/Starter/protobuf-3.1.0/src/libprotobuf.la` The path looks wrong to me… As a result I don’t have `protoc` in my system. ---

@akonakov do you by any chance have a space in the root directory? Like the following **Starter** and **Starter 2**. If the root directory has a space like **Starter 2** it could be possible the script **./protoInstallation.sh** will not be able to find the path. As shown below: ![](https://raywenderlich-com-v3-forums.s3.amazonaws.com/original/3X/0/c/0c267410cb9c44c2f881637bbc78b9d436dc74ce.png) Another alternative is to try to install protoc manually with the following: ``` cd ./protobuf-3.1.0/ ./configure make make check sudo make install sudo ldconfig # refresh shared library cache. ``` Tried to make the script as robust as possible 😕 ---

Yes, the root directory initially had a space in its name - now I’ve renamed it, but still getting the same error. And I can’t find `ldconfig`. No luck for me ☹ ---

@akonakov 1. can you try deleting every single project you downloaded. 2. Clear your trash 3. Can you redownload a fresh copy. Make sure you don’t have duplicate names in the same directory. Spaces are bad with scripts 😃 I think it’s cached. ---

Yeah, it was cached somewhere. Eventually deleted everything unzipped before and extracted again. Now it looks to be OK, thanks, man! ---

@fbara, try looking into /usr/local/bin or /usr/local/bin to remove the protoc libs. ![](https://raywenderlich-com-v3-forums.s3.amazonaws.com/original/3X/a/7/a7490c2447894a68617b8ea941848c3653bd58f4.png) To uninstall flask you could try: > Hope this helps, thanks! ---

This tutorial is more than six months old so questions regarding it are no longer supported for the moment. We will update it as soon as possible. Thank you! :] ---
