undefined reference to '__mulhi3' In function 'vfprintf': and 'calloc'

<< < (5/9) > >>

Ralphxyz:
I am running:

 GNU Make 3.81

and I do not believe I am running the same compiler from the command line as I do in Code::Blocks

From the command line I am running:

gcc version 4.3.3 (WinAVR 20100110)

The Code:Blocks is running something from WinAVR-20090313

I do not know how to see the version in Code::Blocks.

So look at your makefile where the compiler is installed and make sure the avr toolchain im C::B uses the same compiler.

I have gone completely through the Code:Blocks Toolchain pointing to the C:\WinAVR-20100110 folder instead of the default C:\WinAVR-20090313 folder but still get the same errors looking in the WinAVR-20090313 folder.

The WinAVR-20090313 is persistent, in fact there is lots of persistents in the Code::Blocks install if you uninstall and reinstall it still remembers your prior projects, I even went through regedit removing all references to CodeBlocks and a new install still knew about prior projects.

So finally I Googled "undefined reference to `__mulhi3'" and see that there has been a lot discussion on fixing this problem.

One of the most common fixes was to use the -lm flag but how? I do not see anywhere to set the flags.

Now if I was building Code::Blocks from the source files I'd understand this error but seeing as I am just trying to run a default install I just do not understand why I am getting this Compiler Linking error, if that is what it is.

Thanks so much for all of the help.

I will try changing the command line compiler, if I knew how would help.

 :D Solution

I renamed the C:\WinAVR-20090313 folder to zWinAVR-20090313.

Then I ran the Code::Blocks Compiler/Toolchain executables Auto-detect.

Now it found C:\WinAVR-20100110 and instantiated it.

TaDah, it works!!

Here is the Build Log:

Strange no "unused -i" warnings but maybe that is covered in the compile.

Now to move on to my next question!!

Thanks again for the help.

LETARTARE:
hello,
what is :

--- Code: ----LC:\WinAVR-20090313\avr\lib
--- End code ---
since this directory does not exist ?
Cordially.
