Hi all,
I'm trying to use __HrLoadAllImportsForDll with delay loading DLLs, but
I have not been able to make it work. I wonder if anyone could help me
please?
It seems that gcc makes an empty "Delay Import Directory" entry in the
data directory, so __HrLoadAllImportsForDll just fails with 8007007e
(The specified module could not be found).
Is there a way of convincing gcc to make this section? Is this a bug?
(I have "gcc.exe (rubenvb-4.6.3) 4.6.3").
Here's a way to reproduce the problem:
$ cat dll.c
int f(int x) {
return x + 3;
}
int g(int x) {
return x + 4;
}
$ gcc -c dll.c
$ cat delaydll.def
LIBRARY "dll.dll"
EXPORTS
f
g
$ dlltool -d delaydll.def -y delaydll.lib dll.o
$ gcc dll.o -o dll.dll -shared
$ cat test.c
#include <stdio.h>
#include <Windows.h>
int f(int x);
int g(int x);
int main(int argc, char **argv) {
unsigned int i;
i = __HrLoadAllImportsForDll("dll.dll");
if (FAILED(i)) {
printf("Delayed load failed %x\n", i);
exit(1);
}
printf("Result: %d\n", f(5));
printf("Result: %d\n", g(6));
return 0;
}
$ gcc test.c delaydll.lib -o test
$ ./test
Delayed load failed 8007007e
$ objdump -p test.exe
