Hi Tomoki,
Did you happen to run into this issue compiling the test program?
[mdroth@vm qemu-build]$ ls ~/w/vsssdk/inc/win2003/
vdslun.h vsbackup.h vscoordint.idl vsmgmt.idl vsprov.idl
vss.idl vsswprv.idl
vdslun.idl vscoordint.h vsmgmt.h vsprov.h vss.h
vsswprv.h vswriter.h
[mdroth@vm qemu-build]$ cat test.c
#define __MIDL_user_allocate_free_DEFINED__
#include <inc/win2003/vss.h>
int main(void) { return VSS_CTX_BACKUP; }
[mdroth@vm qemu-build]$ gcc -I ~/w/vsssdk/ -o test test.c
In file included from test.c:2:0:
/home/mdroth/w/vsssdk/inc/win2003/vss.h:25:17: fatal error: rpc.h: No
such file or directory
compilation terminated.
I can't seem to locate any mingw or microsoft package that provides that.
It's also not present anywhere on the Wine filesystem I installed the
VSS SDK to.
