Re: libusb harhat/eldk cross-compile problems

You will need to override the configure step for figuring out things via compilation and running. You will need to look at the configure script and see if you can override the sizeof char. (Similarly to how you overrode ac_cv_func_setvbuf_reversed on the command line.) If that is not possible, you will have to hack "configure" with the hard coded value. (To do it "right" you should modify configure.in, then run autoconf. However, that doesn't always work.) --Mark C Doyle wrote:
Hello all,
I'm trying to get the libusb to cross compile using hardhat development
kit. I've also tried it with ELDK but get the same error in the
./configure
script. Note the last line in the screen grab below......Does this mean I
will not be able to get it to work?? If anyone has got it to work can you
let me know what flags and/or compiler preprocessing you done? Thanks v
much
