“libtypec” is aimed to provide a generic interface abstracting all platform complexity for user space to develop tools for efficient USB-C port management. The library can also enable development of diagnostic and debug tools to debug system issues around USB-C/USB PD topology.

linux build issue on x86_64 #1

Closed satmandu closed 2 years ago

satmandu commented 2 years ago

I had to make some edits to get the utils build to start:

sed -i 's,CMAKE_CURRENT_LIST_DIR}/../..,CMAKE_CURRENT_LIST_DIR}/..,g' utils/CMakeLists.txt
sed -i 's,PROJECT_ROOT}/libtypec/bin,PROJECT_ROOT}/bin,g' utils/CMakeLists.txt

But even then I get a build error:

cmake CMakeLists.txt && make

resolved please confirm

That fixed the build issue.

Running it however gives lstypec - ERROR - Failed in Initializing libtypec. strace reveals that it can't find /sys/class/typec on my system. Is there a kernel version/module requirement?
