please help how to compile libsub-1.0 ?

[dony71]

I want to cross compile this utility below, but it needs libusb-1.0
https://github.com/nekromant/pl2303gpio

I check brcm-arm toolchain, but doesn't have ready to use libusb-1.0.so
Anybody can tell me how to cross compile this?

Not sure you're on the right forum. Try https://libusb.info/?

I checked further and found out in fact libusb-1.0 is already available in ~/asus-merlin.ng/release/src/router/libusb10
however this is not the same source like in https://libusb.info
There is no function libusb_get_port_number()

I think I found libusb-1.0 to use which is in directory
asus-merlin.ng/release/src/router/arm-uclibc/install/libusb10/usr/lib
then I manage to compile pl2303gpio / cp2103gpio successfully
however executing pl2303gpio, got segmentation fault
I try to debug using valgrind and show this below
Anybody can help what it means?
