Protobuf compiler version 3.0.0 doesn't match library version 2.6.1 - Aspera Transfer SDK

Have downloaded Transfer SDK from here:

https://api.ibm.com/explorer/catalog...k/doc/overview

Have installed protobuf-2.6.1 from source. Default protobuf that comes with Ubuntu is of higher version.

Code:

    ~$ protoc --version

    libprotoc 2.6.1

cmake .. result:

Code:

    /aspera/transfer-sdk/linux-amd64/connectors/cpp/build$ cmake ..

    -- The C compiler identification is GNU 7.5.0

    -- Configuring done

    -- Generating done

    -- Build files have been written to: .....work/aspera/transfer-sdk/linux-amd64/connectors/cpp/build

It is detecting protobuf 2.6.1 but make doesn't want this version of protobuf.

Code:

    $ make

    Scanning dependencies of target asperatransfer

    [ 14%] Building CXX object CMakeFiles/asperatransfer.dir/transfer.pb.cc.o

    #error regenerate this file with a newer version of protoc.

According to the errors of make I am not sure which version of protobuf does it want?

What more information should I provide here?
Please help.

I am attempting to compile the sample programs from this tar ball: https://api.ibm.com/explorer/catalog...k/doc/overview

What does this error message mean? How am I supposed to upgrade libprotobuf.so found in /usr/local/lib?

Does this mean I am supposed to download and compile protobuf by source? Currently I installed it through apt-get.

I am on Ubuntu 18.04.

Code:

    ~$ which protoc

    /usr/bin/protoc

    

    ~$ protoc --version

    libprotoc 3.0.0

Protobuf is in cmake. If there's a protobuf in your download, there could be a version mismatch. With the typical linux 3 figure versions package-x.y.z, in increment in a number means as follows

z+1 = bug fix
y+1 = feature addition
x+1 = compatability break.

So somehow protobuf-2.n.n is being asked to talk to protobuf-3.n.n and they're incompatible.

I realized that:

Quote:

Found Protobuf: /usr/local/lib/libprotobuf.so;-lpthread (found version "2.6.1")

What should be done to install version 3 of libprotobuf.so?

It should be in cmake. If not find out if your (undisclosed) distro installs it se[paraltely. You mat want to check the lib is found by stuff also.

I deleted this .so manually, and manually installed version 3.13.1.
That solved this problem.
