I am trying to compile the new version of a port I maintain and have
trouble related to std::vector. The code producing the error can be
boiled down to the following test case, which compiles as 64bit but
fails as 32bit.
#include <stdlib.h>
#include <vector>
int main(int argc, char *argv[])
{
int num_layers = 3;
std::vector<const char *> layers (num_layers, NULL);
exit(0);
}
So that should create a vector containing 3 items initially set to NULL.
10.0 compiles ok - both 32 and 64 bit. (libc++)
8.4, 9.2 and 9.3 compiles 64bit but fails on 32bit. (libstdc++)
Using the above code
clang++ -m32 test.cpp
fails with
/usr/include/c++/4.2/bits/stl_algobase.h:641:15: error: assigning to
'const char *' from incompatible type 'const int'
I often get the following with the test case - not the real code.
error: 'operator new' takes type size_t ('unsigned int') as first parameter
I have tried changing num_layers to unsigned int, size_t, std::size_t
How do I fix this to work on 32 and 64 bit?
