Hi!
I can't compile hidtool host application from example of hid-data usage (examples\hid-data\commandline).
That's what mingw says:


windows 7
mingw 3.81
v-usb 20090822

Plus if I try to rewrite the whole code in Code::Blocks, compiler returns "undefined reference to `usbhidOpenDevice(usbDevice**, int, char*, int, char*, int)'"

Well if you could provide the commandline used to invoke compiling?
Maybe you just forgot to specify the right make file?
The right command line would be

ya, I print "make -f Makefile.windows".
Also it doesn't compile if I edit makefile and run "make".

I found another way to compile the example using Code::Blocks IDE.
The solution is to add hiddata.h this way:

Your development environment seems to lack some of the USB driver libs. Did you try MinGW?

I use MinGW
Trere's no other compilers on my computer

I've looked at the error message again. This is an internal error of your gcc. The compiler frontend can't create a process for the preprocessor or another stage of the compiler chain. Your gcc installation seems to be broken.

I use MinGW that goes with Qt package.
Code::Blocks use the same MinGW.

Using codeclocks i can compile the example (I also tested it with MCU with hid-data example firmware), using Makefile.windows and (edited) Makefile - can't.

Then it's probably an issue with search paths (the environment variable PATH).

MinGWs dir name is added to PATH variable

You probably need MinGW's bin directory in PATH, not the MinGW directory itself.

bin path certainly.
"C:\Qt\2009.03\mingw\bin;"

OK. But it's still a kind of internal error: CreateProcess for gcc fails.

I rewrote the host side to fasm. You can find it at http://www.kot3245.ru
In addition, you can compile host side software under linux.
