PsySc0rpi0n Posted July 12, 2018 at 10:32 PM Report #611296 Posted July 12, 2018 at 10:32 PM Boas.

bsccara Posted July 13, 2018 at 11:13 AM Report #611303 Posted July 13, 2018 at 11:13 AM Os erros aparecem porque estás a tentar 'linkar' duas vezes o mesmo ficheiro objecto 'debounce.o'; verifica a linha de comandos usada para 'linkar' o ELF. Quanto ao motivo para isso, usa uns '@echo' no Makefile para verificar o conteúdo das variáveis ALL_CFLAGS e OBJ e procura a segunda referência ao ficheiro. 1 Report

PsySc0rpi0n Posted July 17, 2018 at 09:18 PM Author Report #611375 Posted July 17, 2018 at 09:18 PM Neste caso foi mesmo ignorância. Ao adicionar um assembly file à lista de ficheiros a gerar pelo 'make', estava implicitamente a obrigar o compilador a criar o file debounce.o pela segunda vez. Mas como não preciso do assembly file, retirei-o da configuração do Makefile e já funcionou! 1 Report Kurt Cobain - Grunge misses you Nissan GT-R - beast killer
