Compilation error on master

[Dimitar Misev]

I'm not able to compile current master (g++ version 4.9.2):

[HOSTCXX] Compiling src/compiler/csharp_generator.cc

Here's the configure command:

./configure --prefix=/home/dimitar/projects/rasdaman/community/install --with-pic --with-netcdf --disable-java --with-debug-symbols --with-default-basedb=sqlite --with-filedatadir=/d/rasdata

The repo is a fresh clone.

You might have a previous protobuf version installed on your computer. GRPC first tries to use the global one. It might help to uninstall the global one.

You're right, I found some stuff in /usr/local/. After removing them now I have this problem. Btw do I need protoc from packages or not?

You shouldn't need anything global related to grpc or protobuf. GRPC comes bundled with protobuf and we build it statically so there shouldn't be any need for any linux library.
Not sure about this error, are you sure there's no header somewhere else in the include path?
I've been building it for OSGeo twice yesterday and today and it worked fine for me.

@atoader: Can we force grpc to use the protobuf it comes bundled with? It seems quite problematic for users that install from source, what if he installs some other package that puts protobuf in the global include paths?

[Alex Toader]

Make sure to remove GRPC and Protobuf from your system or install the version we are using on your system.
I will present a more comprehensive solution to this problem at our next group meeting. But, if you have time, you can implement a check in third_party/Makefile.am which checks for Protobuf on the user's system and stops the build if it encounters a version older than 0.12.

[Dimitar Misev]

Ok it worked after really removing anything in /usr I found related to '*protobuf*' and '*grpc*'.

We should put this in the wiki:FAQ or really make sure that the local ones are used as Alex suggested.

[Dimitar Misev]

I added an entry in the FAQ
