[compatibility] undefined reference to `libusb_set_option'

Hi all,

I will try to compile the project on Windows 10 with MinGW-w64 without success.
The error is:
C:/stlink/src/sg.c:972: undefined reference to 'libusb_set_option'

My environement is:

• Windows 10
• texane/stlink 1.6.0 => This version requires the libusb-1.0.22.7z (downloaded manually)
• MinGW-w64 i686-8.1.0-posix-dwarf-rt_v6-rev0

Can you help me?

Complete log of the compilation: log.txt

Thank you in advance.

Please try the develop branch instead. I think there were some fixes related to libusb since Release v1.6.0.

The mentionned error isn't displayed but the compilation failed.

I want to add a remark.

The last log indicates that I have already libusb in my system.
-- Found Libusb: C:/Windows/System32/libusb-1.0.dll
Sure this version is old.

What is your opinion about this.

@purjus74 I think the problem with libusb, that you download manually.
Please remove it. Clear all builds. And try one more time.

Just to give more details:
Before to use your project, my system had already a libusb instance.

If I let the batch mingw64-build.bat to download the libusb-1.0.22.7z, the extraction fails:

...
-- Could NOT find Libusb (missing: LIBUSB_INCLUDE_DIR)
-- downloading libusb 1.0.22

It seems that the archive is file is corrupted :(

@slyshykO: You are right, I did not notice at first that an external libusb library was present.

I think this behavior (error during libusb-1.0.22.7z extraction) is due to my compagny protection :(
This f*#! protection creates the wanted archive file but it contains an error html page !!!

But I'm not sure that is a problem to download before the good libusb archive and put it inside the build folder.
My first log illustrates that the mingw64-build.bat finds the archive, extracts it and uses it:

-- libusb archive already in build folder

@purjus74: Does your whole compilation succeed now?
@slyshykO: I think we should add a note to the instructions on not to use external libusb packages when installing on windows, as this is not the first issue of its kind.
