dependencies - Get makefile to build two targets from the same file but with different flags -


i'm changing project makefile in order build executable same passing different flag compiler.

before changing it, makefile this:

    targets = elilo.efi      : check_gcc $(subdirs) $(targets)      elilo.efi : elilo.so      elilo.so : $(files)     elilo.o : elilo.c $(arch)/sysdeps.h     ...     $(subdirs): dummy         $(make) -c $@     ...     include make.rules

where:

  • $(subdirs) stores subdirs of project
  • $(files), store .o files must created in order link elilo.so
  • and check_gcc checks compiler version , exits if needed

additionally, make.rules contains general rules compile , link files:

%.efi: %.so      $(objcopy) -j .text -j .sdata -j .data -j .dynamic -j .dynsym -j .rel \            -j .rela -j .reloc --target=$(format) $*.so $@  %.so: %.o      $(ld) $(ldflags) $^ -o $@ $(loadlibes)  %.o: %.c         # rule number 1     $(cc) $(incdir) $(cflags) $(cppflags) -c $< -o $@ # rule .s %.o: %.s      $(cc) $(incdir) $(cflags) $(cppflags) -c $< -o $@

my try:

so far, i've tried following in order have new target , be able compile them both rule

targets = elilo.efi usb  : $(targets)  elilo.efi : check_gcc $(subdirs) elilo.so         touch $@.touch  elilo.so : $(files)  .phony : usb usb : check_gcc $(subdirs)     cflags += "-dboot64" $(make) boot64.efi     touch $@.touch  boot64.efi : elilo.so     $(objcopy) -j .text -j .sdata -j .data -j .dynamic -j .dynsym -j .rel \            -j .rela -j .reloc --target=$(format) $> $@

with make.rules:

%.efi: %.so      $(objcopy) -j .text -j .sdata -j .data -j .dynamic -j .dynsym -j .rel \            -j .rela -j .reloc --target=$(format) $*.so $@  %.so: %.o     $(ld) $(ldflags) $^ -o $@ $(loadlibes)  %.o: %.c usb.touch elilo.touch     # rule number 1     $(cc) $(incdir) $(cflags) $(cppflags) -c $< -o $@ ...

but doesn't change i've made rule number 1 stops when making $(subdirs), because rule general affects every object file in project directory , sub-directories...

basically, want is build boot64.efi elilo.efi passing flag -dboot64 compiler .c files change behaviour. tips on how that?

i think shoud rm elilo.so :

usb : check_gcc $(subdirs)     rm elilo.so     cflags += "-dboot64" $(make) boot64.efi     touch $@.touch

because if elilo.so build without "boot64" won't rebuild

javascript - Mootools wait with Fx.Morph start -

i trying var effect = new fx.morph(testmorph, { wait/delay 2 seconds before starting. ( fiddle here ) but when try .wait(2000) or .delay(2000) , or .wait(2000, effect) uncaught typeerror: object [object object] has no method 'delay' any ideas how working? code i'm using: var testmorph = document.id('testmorph'); var effect = new fx.morph(testmorph, { transition: 'back:out', duration: 900, link: 'chain' }).start({ 'top': 20, 'opacity': 1 }).start({ 'border-color': '#a80025', 'color': '#a80025' }); effect.delay(2000); you can use combination of chain() , delay() achieve desired effect. new fx.morph(testmorph, { transition: 'back:out', duration: 900, link: 'chain' }).start().chain(function(){ this.start.delay(2000,effect,{ //first }); }).chain(function(){ this.start({ //second }); }); the
