Problem with Build

Hi Folks,

I just installed Code::Blocks version 8.02 today, and it seems great so far, except for this problem when I try to build a project:


--- Quote ----------------- Build: Debug in RobostixStabilitySystem ---------------

Linking console executable: bin/Debug/RobostixStabilitySystem.elf
/usr/lib/libm.so: file not recognized: File format not recognized
Process terminated with status 1 (0 minutes, 0 seconds)
0 errors, 0 warnings
--- End quote ---

I'm using the AVR-GCC compiler version 4.3.2 in Ubuntu version 9.04, and am compiling for the ATmega128. Any suggestions?

Thanks!

Read the FAQ and turn on full compiler logging.
Verify the project is using correct compiler with proper project settings.

Thanks for the reply!

I turned on full compiler logging and now I get the following output:

A wild guess from a windows user; but, does "/usr/lib" contain the proper libraries for the embedded AVR compiler?

Jenna:
Is your system 64- or 32-bit ?

I'm not sure whether the avr-cross-linker should link against the systems libm.so, but it might be correct.
But if you have a 64-bit and need 32 it will not work.

In this case you need the 32-bit libs also, the package you need in this case is most likely ia32-libs-dev.
And you should use /usr/lib32/ as linker-searchpath in this case.

Please be aware, that all I posted is only correct, if the cross-compiler uses the systems libc6 and is 64-bit.

Most likely all wrong.

I just looked into the debian package list.
Do you have avr-libc installed ?
