Hi!
I've compiled a Atari ST emulator that can record video. The one I've
compiled the emulator crashes when the recorded video reaches a certain
size and from what I can gather it's because off_t is 32bit, even if the
the compiler is x86_64.
Using built-in specs.
COLLECT_GCC=/opt/cross-mingw-w64/bin/x86_64-w64-mingw32-gcc
COLLECT_LTO_WRAPPER=/opt/cross-mingw-w64/bin/../lib/gcc/x86_64-w64-mingw32/7.3.1/lto-wrapper
Target: x86_64-w64-mingw32
Configured with:
/home/solskogen/mingw-w64-builder/trunk/bin/gcc/configure
--prefix=/home/solskogen/obj/cross-mingw-w64
--libexecdir=/home/solskogen/obj/cross-mingw-w64/lib
--target=x86_64-w64-mingw32 --disable-nls --enable-fully-dynamic-string
--enable-libstdcxx-time=yes --enable-languages=c,c++
--disable-libstdcxx-pch --enable-checking=release --enable-lto
--disable-dw2-exceptions --enable-libgomp --enable-threads=posix
--disable-multilib --with-sysroot=/home/solskogen/obj/cross-mingw-w64
mingw-w64 is from the 5.x branch of mingw-w64.
With the compiler I used I get this with a small program:
sizeof off_t: 4 bytes
While on Linux
sizeof off_t: 8 bytes
solskogen@friend:~/temp$ cat test.c
#include <stdio.h>
int main(int argc, char *argv[])
{
printf("sizeof off_t: %lu bytes\n",sizeof(off_t));
return 0;
}
