Hi everybody,
First, I'm not sure if the "dev" mailing-list is the right place as I
don't feel like I'm "participating". So please, forgive me if I'm at the
wrong place.
I'm currently trying to use Xerces by cross-compiling it with Mingw
(hosting on Debian Linux). The problem is that I get an "illegal
instruction" in XMLPlatformUtils::Initialize() when testing it on the
target host. I searched for hours on the web for this issue, but nothing
helped me.
Here the test code:
=====================================================================
#include <xercesc/parsers/SAXParser.hpp>
XERCES_CPP_NAMESPACE_USE
int main(int argc, char *argv[])
{
(void)argc;
(void)argv;
XMLPlatformUtils::Initialize();
{
SAXParser parser;
parser.setValidationScheme(SAXParser::Val_Always);
parser.setDoNamespaces(true);
parser.setDoSchema(true);
parser.setValidationSchemaFullChecking(false);
}
XMLPlatformUtils::Terminate();
return 0;
}
=====================================================================
And here is a gdb output on the target host:

What could be wrong?
Please note that I'm using mingw-cross-env for this purpose
(http://mingw-cross-env.nongnu.org/) and the thing builds Xerces
successfully.
Thanks in advance for your help.
