I'm researching an issue when started regedit.exe
fails to export registry. This started to happen after
Alexandre's patch which included "config.h" in the
regedit source file.
I found out this problem was triggered by declaration
#define _FILE_OFFSET_BITS 64
in config.h. The test case:
********************************************
/* Set this to 64 to enable 64-bit file support on
Linux */
#define _FILE_OFFSET_BITS 64
#include <stdio.h>
#include <windows.h>
void test_write(void)
{
FILE *f = fopen("1.reg", "w");
printf("sizeof FILE: %d\n", sizeof(FILE));
fputs("DEBUG1\n", f);
fclose(f);
}
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE
hPrevInstance,
LPSTR lpCmdLine, int nCmdShow)
{
test_write();
exit(0);
}
********************************************
Comment out the macro definition and it works, with
macro it creates file of 0 length.
With the defined macro many file functions are defined
as functions for 64-bit access and are linked to the
native platform calls instead of msvcrt ones.
Differences in precompilation output:
Without macro:
# 203 "/usr/include/stdio.h" 3
extern FILE *fopen (__const char *__restrict
__filename,
__const char *__restrict __modes)
;
With macro:
# 211 "/usr/include/stdio.h" 3
extern FILE *fopen (__const char *__restrict
__filename,
__const char *__restrict __modes)
__asm__ ("" "fopen64");
The same happens for some other file functions.
What is the correct fix for this problem?
