Cross compiling for PowerPC

[Tergeist P]

Hi,

I'm using protobuf-2.4.1 and I would like to make cross compiling for PowerPC. I've a linux box (Linux 2.6.10). So :

./configure --host=powerpc-405-linux-gnu CC=powerpc-405-linux-gnu-gcc CXX=powerpc-405-linux-gnu-g++

make

=> protobuf/src/protoc :line 136: /protobuf/src/.libs/lt-protoc :cannot execute binay file
=> protobuf/src/protoc :line 136: /protobuf/src/.libs/lt-protoc :success
=> make: ***[unittest_proto_middleman] Error 1

Would you mind helping me please?

Best regards,

Tergeist P.

you have to use the '--with-protoc' option when configuring, please have a look at readme.txt (line 80).

enjoy,

Hi,

Thanks, I hadn't seen the "Note for cross-compiling" in the README! But now, I have a new problem :

./configure --host=powerpc-405-linux-gnu CC=powerpc-405-linux-gnu-gcc CXX=powerpc-405-linux-gnu-g++ --with-protoc=protoc

make

make install

=>No problem. But then I try to use protoc cross-compiled :

protoc Data.proto

     =>tools/bin/protoc: 1: Syntax error: word unexpected (expecting ")")


Would you mind helping me please? I'm using google protocol buffer since several months without any problem but it's the fisrt time
I try to use protoc in cross-compiling so i have some dificulties...

Thanks,

Tergeist P.

Hi,

I try again with a make check this time and I have some errors :

make uninstall

./configure --host=powerpc-405-linux-gnu CC=powerpc-405-linux-gnu-gcc CXX=powerpc-405-linux-gnu-g++ --with-protoc=protoc

make

make check

=>some errors :
