undefined references #2

Hi Marcus,

I tried it on ubuntu 12.04 with clang and libusb installed, but received lots of undefined references. First I thought something is wrong with linking the libusb but it looks allright. What else am I missing? Thanks in advance! David

Hi David,

that looks like it has problems linking against both libstdc++ and libusb. What's your version of them as well as of clang?

Update: also you could try the fork at chrstn-hntschl/k290-fnkeyctl@a40bf6b63 which has been modified to work in Ubuntu.

Thanks for the quick reply!

libstdc++.so.6.0.16 libusb-0.1.so.4.4.4 and clang: Ubuntu clang version 3.0-6ubuntu3 (tags/RELEASE_30/final) (based on LLVM 3.0) Target: x86_64-pc-linux-gnu Thread model: posix

Hello again, the problem for me was the -std=c++11 flag. When I used -std=c++0x instead it compiled. Thanks a lot! it is working properly. David

Great to know, thanks for the feedback! Maybe I should write a proper Makefile after all... :smirk:
