Hi,
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

Code:
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 to 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?
