Re: [avr-gcc-list] avr-libc

[Kaan Akşit]

I have also noticed during avr-gcc compile; there is this warning appearing from time to time:

limits.h: present but cannot be compiled

I have export a path before I install avr-gcc. I noticed that I have set PREFIX for avr-binutils as /usr but for avr-gcc it is /opt/toolchain/avr so I have recompiled everything from the scratch. Now it seems avr-libc is compiling! Thanks Senthil

But now I receive this during the make process of avr-libc :(

Clearly, it's not the AVR assembler that's running.

Did you build avr binutils and avr gcc as per the procedure outlined in http://www.nongnu.org/avr-libc/user-manual/install_tools.html? In particular, did you add the installed binutils directory to the PATH environment variable before building avr-gcc?

Senthil
