@Johann: Is the Readme.rst at https://github.com/hansiglaser/pas-libusb
up to date ?
It states that only the legacy version 0.1 of libusb is supported, but
the binary package for Windows on libusb.info is in version 1.0.22.
You can get source code for old versions of libusb on github but it
seems at first glance that there are no release of windows version
before 1.0.20 (14 sep 2015) (
https://github.com/libusb/libusb/releases?after=v1.0.21-rc4 ).
I tried to compile TestFirmware.pas on windows, I made a few
modifications. I join the diff files.
In ezusb.pas I replaced the dependency to Errors unit by a quick and
dirty rewrite of StrError function, just to allow compilation.
In paslibusbutils.pas I replace the call to fpGetTimeOfDay by a call to
DateTimeToUnix(Now), I'm not sure may be the result of DateTimeToUnix
is truncated to seconds where fpGetTimeOfDay gives a result in microseconds.
In usb.pas I duplicated some constant definitions from errno.inc
included in unit BaseUnix: ESysETIMEDOUT, ESysEAGAIN...
I also replaced the call to fpSelect(0,Nil,Nil,Nil,100) by Sleep(100)
which should do the same thing, waiting for 100 milliseconds.
@James: Now, I just get the two final errors "Import library not found
for c" and "Import library not found for usb".
For now I haven't found which library to use for c.
I'm preparing another mail for this.
