Hi,
I want to know about limit program size.
Because I met error at build phrase about this. (collect2.exe: error: ld returned 1 exit status)
Remove some routine and build I get this result.
text data bss dec hex filename
4764 4 448 5216 1460 RS486_t1.axf

My target board use LPC11U14(LPC11U14FBD48). (Flash 32kb , SRAM 6kb)
code_red info say.
the flash consumption of your application will then be text + data.
the RAM consumption of your application will then be data + bss.

I think still enough memory exist.
Please tell me about cause of the error.

Best Regards,
Fumio Yoshizawa, from Japan.

What are the error messages emitted by the Linker?

Probably you are linking the wrong C library...

I had the same problem with a copied project (create new project and then copy src files) and after following the FAQ found I had C->Misc as Redlib(auto) and Assembler->Arch as Redlib(auto), BUT in the Linker->Manged Linker Script I had Redlib(none), I changed it to Redlib(no host) and all was well.
