Hi,
I'm trying to change some avr-gcc options without success. Changing and copying the makefile has no effect.
I took a look at the arduino IDE source. It looks like the compiler settings are "hard-coded":
static private List getCommandCompilerC(String avrBasePath, List includePaths,
String sourceName, String objectName) {
List baseCommandCompiler = new ArrayList(Arrays.asList(new String[] {
avrBasePath + "avr-gcc",
"-c", // compile, don't link
"-g", // include debugging info (so errors include line numbers)
"-Os", // optimize for size
"-w", // surpress all warnings
"-ffunction-sections", // place each function in its own section
"-fdata-sections",
"-mmcu=" + Preferences.get("boards." + Preferences.get("board") + ".build.mcu"),
"-DF_CPU=" + Preferences.get("boards." + Preferences.get("board") + ".build.f_cpu"),
}));
So how can I change compiler options, e.g. -Os --> -O2; without changing the IDE source code? Are there any tricks I have missed?
Best regards,
