Can't add library to my code

[craigyjp]

I successfully compiled your example and I'm flashing LEDs from a 595, however, I tried to integrate the library into my code and I'm failing miserably. The cmake works fine, but the nmake fails.

Hi, thanks for reaching out.

I've never used or even heard of Nmake but what it seems like is that it is not able to find the cstring standard library. Now, I don't see exactly where it is utilised in the code so the first thing you could try was removing the line altogether. For me it appears to compile, at least with cmake. Again, I don't quite know how Nmake works but if that doesn't work you should look into why the cstring library isn't in your nmake library paths or whatever equivalent it uses.

I am really sorry I couldn't be of any more help, but if you do find a solution I'd be interested in hearing it.

I hope you have a lovely new year's eve and a great year in front of you. Devnol

Many thanks for the speedy reply, I changed to cmake ../ and make, but the make fails now

Well that just says there is a syntax error in your makefile at line 32, doesn't seem to have anything to do with the other error.
