1 | * How to cross compile libftdi-1.x for Windows? * |
2 | 1 - To cross-compile for Win32 with mingw, you need to | |
3 | have libusb-1.0 for Windows. libusbx is a fork of libusb-1.0 | |
4 | project which has gained popularity under Windows and Linux. | |
5 | Therefore the instruction here uses libusbx. The process to | |
6 | use libusb-1.0 from libusb.org is similar but take note it | |
7 | does not offer Windows binary as of Jan 09 2013. | |
8 | ||
9 | 2 - Get libusbx Windows release binary from Sourceforge. | |
10 | http://sourceforge.net/projects/libusbx/files/releases/ | |
11 | ||
12 | 3 - The release version is libusbx-1.0.14-win.7z (706.2KB) | |
13 | as of Jan 09, 2013. | |
14 | ||
15 | 4 - Alternatively you can also build form the release source tar ball | |
16 | or the git source tree following standard cross compile process | |
17 | ||
18 | 5 - Copy include/libusbx-1.0/libusb.h to the include directory of your | |
19 | cross compiler, eg., | |
20 | /opt/cross/i386-mingw32msvc/include/ | |
21 | ||
22 | 6 - Copy MinGW32/static/libusb-1.0.a and MinGW32/dll/libusb-1.0.dll.a | |
23 | to the library directory of your cross compiler, eg., | |
24 | /opt/cross/i386-mingw32msvc/lib/ | |
25 | ||
26 | 7 - Create a build directory like "mkdir build-win32", e.g in ../libftdi/ | |
27 | ||
28 | 8 - edit Toolchain-mingw32.cmake to reflect your cross compiler location. | |
29 | ||
30 | 9 - cd into the build directory and run | |
31 | "cmake -DCMAKE_TOOLCHAIN_FILE=../Toolchain-mingw32.cmake .." | |
32 | ||
33 | 10 - Copy src/ftdi.h to the include directory of your cross compiler, | |
34 | eg., /opt/cross/i386-mingw32msvc/include/ | |
35 | ||
36 | 11 - Copy build-win32/src/*.a to the library directory of your cross compiler, | |
37 | eg., /opt/cross/i386-mingw32msvc/lib/ | |

40 | * How to run libftdi-1.x under Windows * | |
41 | ||
42 | libusbx (or libusb-1.0) Windows backend will rely on a proper driver to run. | |
43 | Please refer to the following wiki page on the instruction of | |
44 | installation of the proper driver. | |
45 | https://github.com/libusbx/libusbx/wiki/Windows-Backend#wiki-How_to_use_libusbx_on_Windows | |
46 | ||
47 | As of Jan 09 2013, libusb-1.0 Windows backend only supports WinUSB | |
48 | and libusbx's support of libusb0.sys and libusbk.sys are considered less | |
49 | mature than WinUSB. Therefore, WinUSB driver installation using Zadig | |
50 | is recommended. | |
51 | ||
52 | Take note once you replace the original FTDI driver with WinUSB driver, | |
53 | you can no longer use the functionality the original FTDI driver provides | |
54 | (eg. Virtual Serial Port or D2XX). |
