Google protobuf and symbian

I need to transfer data between c++ and java. I have decided to use Google's protobuf.

I made installation process and I got: bin > protoc.exe lib > libprotobuf.a libprotobuf.la libprotobuf-lite.a libprotobuf-lite.la libprotoc.a libprotoc.la and include folder

I've link library in .pro file

QT       += core gui network webkit

TARGET = MWOP
TEMPLATE = app

LIBS += -LC:\msys\1.0\local\lib\ -lprotobuf
INCLUDEPATH += C:\msys\1.0\local\include

SOURCES +=
...

HEADERS  += 
...

FORMS    += 
...

CONFIG += mobility

MOBILITY += bearer systeminfo

symbian {

    TARGET.UID3 = xxxxx
    TARGET.CAPABILITY += ReadUserData NetworkServices
    TARGET.EPOCSTACKSIZE = 0x14000
    TARGET.EPOCHEAPSIZE = 0x020000 0x800000

}

RESOURCES += Resources/Registration.qrc

in simulator everything seems t开发者_如何学JAVAo work fine and project builds but when I want to deploy application on phone I've got compilation error: :: error: No rule to make target \NokiaQtSDK\Symbian\SDK\epoc32\release\armv5\LIB\protobuf.dso, needed by \NokiaQtSDK\Symbian\SDK\epoc32\release\gcce\urel\MWOP.exe. Stop.

How can I fix that?

The DSO file you need is the ARM compiled protobuf library. I expect that the libs you list (libprotobuf.a etc) are windows/x86 binaries, so no use for running on target. You need to either:

• get hold of the protobuf source code and build it yourself for ARM
• find pre-compiled ARM binaries for the protobuf library

An alternative is to use the Nokia APIbridge, which can achieve the same thing
