Title: Not compiling before linking
Post by: urt on December 22, 2023, 11:43:17 am
Using Code::Blocks on Windows 10, trying AVR project. The code is fine, verified by other IDE, trying to build the project and getting these messages:

Code
avr-gcc.exe -LC:\WinAVR\avr\lib -o bin\Debug\TESDTS.elf obj\Debug\fuse.o obj\Debug\main.o  -mmcu=atmega328p -Wl,-Map=bin\Debug\TESDTS.map,--cref  
avr-gcc.exe: obj\Debug\fuse.o: No such file or directory
avr-gcc.exe: obj\Debug\main.o: No such file or directory

Feels to me that it doesn't compile them (no binary files to link into elf)
the compiler path is fine, any help?

This is the link log, post a full rebuild log so we can see what is failing when compiling.

I think it really doesn't compile, this is the full build log in HTML format

Did you a full rebuild log? The cleaning stage should be in the log... Please use code tags, as in the original post.

Have you set the compiler executable properly in the compiler properties?.

This page (https://carlossilesblog.wordpress.com/2020/04/29/install-avr-toolchain-with-code-blocks/) shows how executables should be configured:

    C compiler: avr-gcc.exe
    c++ compiler: avr-g++.exe
    linker for dynamic : avr-g++.exe
    linker for static: avr-ar.exe

Just finished following the guide, still not helping
It can't find fuse.o / main.o

I did re-build (CTRL+F11), this is the updated output of the log:

Can you attach the CBP file?

I think that the compiler is not working because there are no *.o files at the directory at all

This looks right to me, although I use Atmel Studio 7 for AVR developing instead of C::B.

Can you attach a screen capture of the Settings->Compiler->GCC compiler for AVR->Toolchain executables tab?
