Can't resolve "input file"

What is the source of this file?  Meaning, what software download did you use to obtain this example?  Please indicate the link.

the call to the linker does not linst any single input file. So the linker does not know what to link.

If you're using an IDE, maybe you didn't add the source file as project source file but just as a normal  file (or not at all). Then the IDE does not know that it needs to be compiled and linked. And since there are no other files to be compilerd and linked, the compiler does nothing and the linker fiinds nothing to link. The compiler won't complain if it isn't invoked at all (because there's nothign to compile), but the linker does, as it IS invoked and there's still nothing to link.

Hi,

I am working through this tutorial: http://software-dl.ti.com/trainingTTO/trainingTTO_public_sw/MSP430_LaunchPad_Workshop/LaunchPad.pdf

When building the project, I get this error:

**** Build of configuration Debug for project Test ****

Any help would be appreciated!!!

When you compile a C program, the linker implicitely adds soem default functions. Those functions copy the init values for your variables from flash to ram or handle integer multiplication/division etc.

In your case, the linker expects the library that contains this code at C:/Program Files (x86)/Texas Instruments/ccsv4/tools/compiler/msp430/lib/libc.a .

This file, however, cannot be found there (wrong path) or is in a wrong format (wrong compiler or wrong version).
Or, which seems to be the case here, the correct version of this file cannot be determined since the linker for some reason cannot determine any input file to link and therefore not detect which version (MSP430/MSP430X/X2, hardware multiplier ot not etc.) is required.

It may have to do with the location of the files:

testabc.c is in ../testabc.c (the parent folder), but the object file seems to be expected in ./testabc.obj (the current folder).
Eclipse is very pickery about what is placed where. Try moving the source file into the project folder or tell the compiler (if this is possible) to output the generated object file to th ecorrect location.

I forgot to save my source file with ".c" at the end.   Once I added this it compiled perfectly.
