PKG_CONFIG_BMDA_Windows

gistfile1.txt

I decided to roll back the BMDA testing to a minimum configuration, involving VSCode, PowerShell, and MSYS2 shell was stepping into areas with their own learning curve and challenges.

So, I went with the simplest of shells, the Windows (formally DOS) Command Line (cmd.exe).

First I checked the "PKG_CONFIG_PATH" variable value in the shell, I found what appeared to be a couple of errors in the environment variable "PKG_CONFIG_PATH". First, the variable doi not have a drive specification, I thought this was a good idea since all my working folders are on a secondary drive. Second, at some point we decided to use the UCRT64 toolchain and had not changed "PKG_CONFIG_PATH" to reflect this. With these corrects the variable looks like:

D:\DataRoot\Projects\blackmagic\src>echo %PKG_CONFIG_PATH%
c:/msys64/ucrt64/lib/pkgconfig

Browsing the MSYS2 installation folder to that folder reveales the libusb-1.0.pc and libftdi1.pc files required by "pkg-config." Note that the "hidapi" library is not installed at present, however, that is not the basic issue at hand.

"pkg-config" fails to find these files:

D:\DataRoot\Projects\blackmagic\src>pkg-config --modversion libusb-1.0
Package libusb-1.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libusb-1.0.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libusb-1.0', required by 'virtual:world', not found
