Link problem on Red Hat 9

Hi all,

I'm moving my application from red hat 7.2 to red hat 9 and I'm facing probleme to get it compiled.

Here is the code

#include <util/PlatformUtils.hpp>

int main(int argc, char * argv[])
{
	//std::string str="Trying to compile some XML stuff";
	//std::cout << str << std::endl;
	// Initialize the XML4C2 system
	try
	{
		xercesc::XMLPlatformUtils::Initialize();
	}
	catch (const xercesc::XMLException & toCatch)
	{
		//std::cout << "Got an error" << std::endl;
	}
}

Here is how I try to compile it
g++ -I/usr/include/xercesc testXML.C -lxerces-c -o testXML

I've installed xercesc 2.2.0 (rpm version)
% rpm -qa | grep xerces
xerces-c-devel-2.2.0-2
xerces-c-2.2.0-2

The library is in /usr/lib and available to the linker
% grep xerces /etc/ld.so.cache
Binary file /etc/ld.so.cache matches

Here are the the errors when compiling (in fact this is the linking that makes problems.)
%g++ -I/usr/include/xercesc testXML.c -lxercesc -o testXML
/tmp/ccmHwbd8.o(.text+0x14): In function `main':
: undefined reference to `xercesc_2_2::XMLUni::fgXercescDefaultLocale'
/tmp/ccmHwbd8.o(.text+0x19): In function `main':
: undefined reference to `xercesc_2_2::XMLPlatformUtils::Initialize(char
const*)'
/tmp/ccmHwbd8.o(.gcc_except_table+0x10): undefined reference to `typeinfo for
xercesc_2_2::XMLException'
collect2: ld returned 1 exit status

I don't quite understand what's going on. Any hint to solve that ?
Thanks

Steel

Shouldn't you use also -L/usr/lib/xercesc (use the path where xerces-c.so 
is found)?

Hi There,

	Your missung the using namespace xercesc;

That should then compile.

Thanks

Pete

Hi all,

I'm moving my application from red hat 7.2 to red hat 9 and I'm facing
probleme to get it compiled.

Here is the code

#include <util/PlatformUtils.hpp>

int main(int argc, char * argv[])
{
	//std::string str="Trying to compile some XML stuff";
	//std::cout << str << std::endl;
	// Initialize the XML4C2 system
	try
	{
		xercesc::XMLPlatformUtils::Initialize();
	}
	catch (const xercesc::XMLException & toCatch)
	{
		//std::cout << "Got an error" << std::endl;
	}
}

Here is how I try to compile it
g++ -I/usr/include/xercesc testXML.C -lxerces-c -o testXML

I've installed xercesc 2.2.0 (rpm version)
% rpm -qa | grep xerces
xerces-c-devel-2.2.0-2
xerces-c-2.2.0-2

The library is in /usr/lib and available to the linker
% grep xerces /etc/ld.so.cache
Binary file /etc/ld.so.cache matches

Here are the the errors when compiling (in fact this is the linking that
makes problems.)

const*)'
/tmp/ccmHwbd8.o(.gcc_except_table+0x10): undefined reference to `typeinfo

xercesc_2_2::XMLException'
collect2: ld returned 1 exit status

I don't quite understand what's going on. Any hint to solve that ?
