undefined reference to `setdefaultif' in network examples

[a_barvar]

Hi,
this is a compile error for network examples: " undefined reference to `setdefaultif' ", when I try compile each example for symbian device by Qt creator 2.0.0 in NokiQtSdk v1.0.
so what's or where's my wrong?

this is fortunserver.pro for example
------------------------------------------------------------------
HEADERS = server.h
SOURCES = server.cpp \
main.cpp
QT += network

# install
target.path = $$[QT_INSTALL_EXAMPLES]/network/fortuneserver
sources.files = $$SOURCES $$HEADERS $$RESOURCES $$FORMS fortuneserver.pro
sources.path = $$[QT_INSTALL_EXAMPLES]/network/fortuneserver
INSTALLS += target sources

symbian {
TARGET.UID3 = 0xA000CF71
include($$[QT_INSTALL_EXAMPLES]/symbianpkgrules.pri)
HEADERS += $$[QT_INSTALL_EXAMPLES]/network/qftp/sym_iap_util.h
LIBS += -lesock -lcommdb -linsock # For IAP selection
TARGET.CAPABILITY = "All -TCB"
TARGET.EPOCHEAPSIZE = 0x20000 0x2000000
}

hi,

check if your missing the header and lib
#include <net/if.h>
libc.lib

Well. It's qt example. so #include <net/if.h> is added in sym_iap_util.h and I add libc.lib in .pro but it didn't solve problem.

"undefined reference" generally means it failed in the link step -- the linker couldn't find the compiled version of the referenced item. This would generally mean you're missing something in SOURCES or missing a DLL/LIB.

Yes, I think it's about linker. But it's an example of NokiQtSdk v1.0 and I think it must be compile without error!!. Setdefaultif is open C function that it's used in sym_iap_util.h and I added libc.lib in .pro as "-llibc" and also "-Lc:\NokiaQtSDK\Symbian\SDK\epoc32\release\armv5\lib\libc.lib" but nothing happend.

HEADERS = server.h
SOURCES = server.cpp \
main.cpp
QT += network

# install
target.path = $$[QT_INSTALL_EXAMPLES]/network/fortuneserver
sources.files = $$SOURCES $$HEADERS $$RESOURCES $$FORMS fortuneserver.pro
sources.path = $$[QT_INSTALL_EXAMPLES]/network/fortuneserver
INSTALLS += target sources

symbian {
TARGET.UID3 = 0xA000CF71
include($$[QT_INSTALL_EXAMPLES]/symbianpkgrules.pri)
HEADERS += $$[QT_INSTALL_EXAMPLES]/network/qftp/sym_iap_util.h
LIBS += -lesock -lcommdb -linsock -llibc -Lc:\NokiaQtSDK\Symbian\SDK\epoc32\release\armv5\lib\libc.lib # For IAP selection
TARGET.CAPABILITY = "All -TCB"
TARGET.EPOCHEAPSIZE = 0x20000 0x2000000
}

I'm no expert at this, but I THINK you should drop the "libc.lib" from your -L. As I understand it that just specifies a search directory, not the specific file.

[a_barvar]

Ok. Yes sorry for my mistake writting, I used -L without libc.lib

LIBS += -lesock -lcommdb -linsock libc.lib -Lc:\NokiaQtSDK\Symbian\SDK\epoc32\release\armv5\lib

By the way, qmake generate .mmp file and all libs are exist.

transferserver_0xA000CF71.mmp:


LIBRARY insock.lib
LIBRARY commdb.lib
LIBRARY esock.lib
LIBRARY libstdcpp.lib
LIBRARY QtGui.lib
LIBRARY QtNetwork.lib
LIBRARY QtCore.lib
LIBRARY libc.lib
LIBRARY libm.lib
LIBRARY euser.lib
LIBRARY libdl.lib
STATICLIBRARY qtmain.lib

it seem all of thing is correct but the linker error still is exist.

[danhicksbyron]

Could be a C/C++ thing -- name mangling.

Thanks for replay. I think I found the problem. It's about NokiaQtSdk v1.0. Open C used in NokiaQtSdk is older also header files have setdefalultif (if.h) but the library (libc.lib) hasn't this function. This function is exist in openC 1.6.
