Dears,
unfortunely I am new in gcc compiler.
I wok on Windows XP Home - SP3.
I had a problem in AVR Toolchain, which uses gcc 4.5.1
It seems maybe they have an adapted gcc version
"gcc (AVR_8_bit_GNUToolchain_3.3.1_422) 4.5.1"
I also downloaded and installed cgwin. It contains gcc 4.5.3
Because of I am novice in gcc, at the moment I did not try to
reproduce the problems with the gcc 4.5.3 inside cgwin.
I have three problems :
- internal error in the linking phase (warning)
- function declared 'noreturn" has a 'return' statement
given on a function where no return statement appears
- a function call which disappears when the firmware is built
The same function call does not disappear if it is written
in an equivalent but different style.
At the moment I posted all details on AVR Freaks :
http://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewtopic&p=914857#914857
Please, let me know if you can help me to try to reproduce the problem
in gcc 4.5.3 in cgwin
I attach the Output of AVR Studio, which shows the make commands performed.
Best Regards,
Mauro.
