Hello,
I installed MinGW on Debian. And the compiler reported warnings and
potential bugs.
I fixed most of the warnings. See the pull request [1].
The remaining warnings are:
../../libusb/os/windows_usb.c: In function 'windows_init':
../../libusb/os/windows_usb.c:879:18: warning: cast from function call
of type 'uintptr_t' to non-matching type 'void *'
[-Wbad-function-cast]
../../libusb/os/windows_usb.c: In function 'windows_get_device_list':
../../libusb/os/windows_usb.c:1318:2: warning: missing initializer
[-Wmissing-field-initializers]
../../libusb/os/windows_usb.c:1318:2: warning: (near initialization
for 'dev_info_data.ClassGuid') [-Wmissing-field-initializers]
The line
SP_DEVINFO_DATA dev_info_data = { 0 };
may be missing some initializers
../../libusb/os/windows_usb.c: In function 'winusbx_claim_interface':
../../libusb/os/windows_usb.c:376:30: warning: 'dev_info' may be used
uninitialized in this function [-Wuninitialized]
../../libusb/os/windows_usb.c:2672:11: note: 'dev_info' was declared here
This may be a real bug.
dev_info is set only if (_index <= 0) in the previous lines.
Maybe a else statement is missing?
../../libusb/os/threads_windows.c:137:1: warning: '__inline' is not at
beginning of declaration [-Wold-style-declaration]
../../libusb/os/threads_windows.c: In function 'usbi_cond_timedwait':
../../libusb/os/threads_windows.c:190:2: warning: nested extern
declaration of 'epoch_time' [-Wnested-externs]
Bye
