[Mingw-users] Trying to develop some USB code - libhid.a issues

[Alex J L. <ajl...@or...>]

Hi,

I've been taking a look at MinGW to allow me to access some Human Interface
Device
(HID) USB clients.

I had a few problems with undefined symbols that seem to come down to an
"old" version
of libhid.a and associated export definitions.

e.g.

devices.o(.text+0x5d):devices.c: undefined reference to
`_imp__HidD_GetHidGuid@4'
devices.o(.text+0x1c3):devices.c: undefined reference to
`_imp__HidD_GetAttributes@8'
devices.o(.text+0x234):devices.c: undefined reference to
`_imp__HidD_GetAttributes@8'
devices.o(.text+0x2f2):devices.c: undefined reference to
`_imp__HidD_GetHidGuid@4'

I'm not 100% sure that was the original problem but the original libhid.a
doesn't
seem to include the HIdD_xxx() exports I need.

As a consequence I have built an include file with the additional exports
and a new import library from the .def to replace libhid.a. Things seem to
work ok now.

Is this something that I could contribute as a patch?
Who would be best to talk to about this?

(Apologies if there are docs on this I've missed)

Best,

Alex/
