protobuf-python26: error: 'google/protobuf/descriptor.h' file not found

[thekilon@…]

Macports can't install protobuf-python26 on Lion.

here is the log file

​http://www.pasteall.org/26232

I tried both my macs I am getting exactly the same error , both having Lion installed and of course the latest Xcode

Tried this

sudo port clean protobuf-python26
sudo port install protobuf-python26 configure.compiler=llvm-gcc-4.2

and this

sudo port clean protobuf-python26
sudo port install apple-gcc42
sudo port install protobuf-python26 configure.compiler=apple-gcc-4.2 configure.cxx=g++-apple-4.2

still the same error

another use that tries the same thing but from snow leopard does not have this issue

You are certain the error "error: 'google/protobuf/descriptor.h' file not found" is the same when using llvm-gcc-4.2? That file should have been provided by dependency protobuf-cpp (was it? -- check with "port contents protobuf-cpp") and I was going to guess the error was because you're using clang, and ​clang doesn't use CPATH / LIBRARY_PATH, but that wouldn't affect llvm-gcc-4.2.

Thanks, I can reproduce it. I have the package installed on Lion, but now it fails to compile.

Commenting out all the PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=cpp lines in the Portfile gets it to compile, but it should continue to work.

Found a fix, working on a patch now.

yes ryan the file does exist, and yes it reports the same error, don't know why it can't compile it. Maybe blair does ;) thank you both for responding so quickly.

I was trying to compile mypaint on Lion and came against this error but even if i try to install it separately again I get the error.

Fixed in r87096. Your next 'port -v sync' that updates your Portfiles should fix it.
