Re: [avr-gcc-list] Specifying crt*.o file

[Anton Erasmus]

Hi,

If I specify the crt file explicittely on the command line, I get 
"Duplicate Symbol" errors. It seems that the default crt file is still 
linked in as well. I cannot find the option, that tells gcc not to link 
in the default crt file.

The -nostartfiles option that reinhard jessich suggested, gives the 
warning "unknown option nostartfiles". 

For the moment I have edited the specs file to change the name of 
the default crt file, but this is a complete hack.

Regards
   Anton
