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

[Ralphxyz]

  I really do not know where even to begin.

I am a new user of Code:Blocks.

So far I have had a time getting my #includes "..." to work, but I have them working now.

But what about these errors:



This is using the C:\WinAVR-20090313 compiler.

Using the Atmel Toolchain I am able to build and compile my code without problems but that is using a different version of the AVR-GCC compiler.

How would I point Code:Blocks to the newer AVR-GCC compiler? Actually I cannot find the Atmel AVR Toolchain there is this notation in my Path C:\Program Files (x86)\Atmel\AVR Tools\AVR Toolchain\bin but that does not work for the Compiler's installation directory in Code:Blocks so I have to fix these undefined references problem.

Thanks for the help,
Ralph

Have you tried setting up a compiler in Settings -> Compiler?

Have you tried setting up a compiler in Settings -> Compiler?

Short answer "yes" now what?

I think that answers both of my replies, thank you.

The default installed AVR-GCC compiler gets these "undefined reference" errors pointing to the compiler libraries
nothing that I have control over.

You need to figure out what is missing.

Once, you do that it is likely someone can tell you where to add it.

If you want; the link below should help you fix it yourself.

Now this is just a default installation of Code:Blocks.

The problem is with the installation of Code:Blocks.

I guess my first thing to do would be to re-install code blocks.

I take it this is not a common error.

I re downloaded Code:Blocks and re-installed!!

I am still getting the same undefined reference to '__mulhi3' .



Now this isn't just a undefined reference to one of my libraries this is a compiler library!!

There definitely is a problem with the Windows 8 x64 install.

FYI: I am 99.99 % sure the problem is a Compiler or CB Toolchain configuration issue.

Feel free to keep re-installing Code::Blocks; it won't fix this problem.

You do not seen wish my help, so goodbye.

Have you tried to build from the command line? Does it work there?

Posting screen shots of the result is useless. Look at the "Build log" for clues.

[Ralphxyz]

If you installed the compiler on its default installation directory, there is nothing more to configure. Launch Code::Blocks and you 're all set

no I am not!!

I appreciate all of your help and I am trying to apply your help.

How do you run the Code:Blocks compiler from the command line.

I run fine from the command line but that is using a different compiler gcc version 4.3.2 (WinAVR 20090313).

Where is the build log? Like I said I am brand new to Code:Blocks.

Have you setup C::B to use the correct compiler?

[danselmi]

Can you post the full buildlog? Mmcu must be defined the same for compile and link phase.

I have not setup anything!! I just did a install. Actually I have hit the Auto-detect button a couple of times:

Again where is the build log?

Thanks for the help.

Are others running Windows 8 x64?

Again where is the build log?

Are you kidding ?
You have posted a screen shot, that shows a tab, that is named "Build log".
It might help to click on the tab, even if there are other ways to reach it.

[Ralphxyz]

Sorry I was not looking at anything but the error message.

Speaking of which the screen shot I posted essentially says the same thing as the the Build Log, which I have finally seen.
