Problem with COINES v2.7.0 libusb on macOS (arm64)

[oggyshooy]

Hi, 

I've successfully got COINES v2.7.0 to build (all the included examples) on a Windows machine, using Cygwin. I need it to also run on my macbook (M1 chip, arm64), which should be supported, but I keep hitting a problem with libusb. 

It seems COINES only comes with a libusb-1.0.a for mingw (x84 and x64). So, I cloned the libusb from Github and built the .dylib specifically for "All Mac" as per the guidelines here: https://github.com/libusb/libusb/wiki/FAQ/4dcab89c98a65c1151537d4949dca477119e1128#does-libusb-suppo...

I then copied the built libusb-1.0.0.dylib into the libusb-1.0 folder of COINES, and tried to recompile but I still get the same error: 

ld: library not found for -lusb-1.0

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Disclaimer: I'm not a software engineer, have limited DIY experience with makefiles. 

Best wishes,

Oliver

Hi oggyshooy,

Do you mean you installed COINES_v2.7.2_MacOS_Beta(download from https://www.bosch-sensortec.com/software-tools/tools/coines) and compiled Coines example code, and got the following error information?
ld: library not found for -lusb-1.0
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Hi BSTRobin

Yes, indeed I downloaded the shell script from that link you posted. After running, it actually installs on my system as "COINES v2.7.0", even though I can see the install shell script says 2.7.2.

I just tried reinstalling, and I guess the default install location path has not been updated in the install shell script. Nonetheless, running the shell script fails with this output:

[ MAKE ] coines-api
[ AR ] libcoines-pc.a
[ LD ] app_switch
ld: library not found for -lusb-1.0
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [app_switch] Error 1
COINES installed successfully!

I guess the problem is that COINES doesn't come with libusb for macOS, only mingw. Perhaps there's a way to force it to use my system's installation (I definitely have libusb installed via homebrew).
