Dear Hari,
sounds like an error message difficult to find the origin for...
Does the file
/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../x86_64-linux-gnu/libdl.so
exist on your system, or does it point to a valid library?
Did, for any reason, you build parts of the code for 32bit instead of
64bit?
Can you compile any program with dynamic linking on your system? Try
e.g. test.cpp
/* test.cpp */
#include <cmath>
#include <iostream>
int main() {
double d = std::sqrt(3.141);
std::cout << d << std::endl;
return 0;
}
/* end test.cpp */
with 'g++ test.cpp -lm -otest'
Regards,
Tim
