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?
