protobuf3-cpp version 3.6.1 conflicts with opencv @3.4.1_2+contrib+python27

Reported by: jtressle Owned by: stromnov (Andrew Stromnov)
Priority: Normal Milestone:
Component: ports Version: 2.5.3
Keywords: Cc:
Port: protobuf3-cpp opencv


Latest version of Opencv with contrib and python27 no longer compiles with protobuf3-cpp.

protobuf3-cpp 3.6.1 causes issues because PROTOBUF_CONSTEXPR is unknown.

Last version of protobuf3-cpp (3.5.1) worked.

I just now was able to build and install opencv+contrib+python27 by downgrading protobuf3-cpp to version 3.5.1.

Any update on this? Same issue has happened on Opencv 3.4.3.

While this gets fixed, I managed to get around this bug by replacing -DBUILD_PROTOBUF=NO with -DBUILD_PROTOBUF=YES in /opt/local/var/macports/sources/, then rebuilding opencv :

sudo port clean opencv
sudo port install opencv +contrib+java+python27+python36+qt5

Before doing so, make sure protobuf3-cpp is installed so that you have the command protoc to generate the headers compatible with your protobuf library version:

sudo port install protobuf3-cpp

Hope this helps
