Centos 7.4 #47

undefined reference to `cnpy::npz_load(std::cxx11::basic_string<char, std::char_traits, std::allocator >, std::cxx11::basic_string<char, std::char_traits, std::allocator >)'

I'm taking a project that compiles and runs on Ubuntu 16.04 to CentOS 7.4. For some reason, CentOS is not detecting the cnpy library. I've done the make/make install on the device and copied the libcnpy.a/.so everywhere I can think.

Anyone have an idea of why it is still having trouble finding the library?

Thanks

Hi Tony,

I'm having the same issue, and it's kind of driving me up the wall. Did you ever figure it out?

Best regards, Tynan

EDIT: The issue seems to have been either an outdated or mismatched GNU compiler. GNU 7.2.0 was installed on the system, but cmake was using GNU 4.8.5

Hello Zening-Li,

Yes, I did figure out what the problem was, at least on my machine. I was unintentionally running cmake with an outdated GNU compiler. Once I directed it to the updated version, everything worked properly. Hopefully that’s all you need to do too!

Best regards, Tynan
