As know is enough:
Quote
if (files.endsWith(".c") || files.endsWith(".cpp"))

and replace it with this line:
if (files.endsWith(".S") || files.endsWith(".c") || files.endsWith(".cpp"))

This was already added (I think) in Version 0017.
The topic you refer to is 2 years old!

Yes, arduino compiles ".S" file - I have set option "preproc.save_build_files=true" and find "ffft.S.o" in TEMP dir.

Here output with "build.verbose=true":
Code: [Select]

\avr\bin\avr-gcc -c -g -assembler-with-cpp -mmcu=atmega328p -DF_CPU=16000000L -DARDUINO=18 -I\arduino-0018\hardware\arduino\cores\arduino -I\arduino-0018\libraries\IRremote -I\arduino-0018\libraries\ffft -I\arduino-0018\libraries\ffft\utility \arduino-0018\libraries\ffft\ffft.S -o\Temp\build.tmp\ffft\ffft.S.o



But linker does not find functions in "ffft.S.o"!
Code: [Select]
\avr\bin\avr-gcc -Os -Wl,--gc-sections -mmcu=atmega328p -o \Temp\build.tmp\ColorMusic.cpp.elf \Temp\build.tmp\IRremote\IRremote.cpp.o \Temp\build.tmp\ffft\ffft.S.o \Temp\build.tmp\ColorMusic.cpp.o \Temp\build.tmp\core.a -L\Temp\build.tmp -lm

o: In function `loop':
\Temp\build.tmp/ColorMusic.cpp:45: undefined reference to `fft_input(int const*, _tag_complex_t*)'
\Temp\build.tmp/ColorMusic.cpp:46: undefined reference to `fft_execute(_tag_complex_t*)'

extern "C" {

// Put your function prototypes here

}

Ohh, thanks! It's worked!
I had not thought about C++ to generate names...
