Eu instalei o conjunto de ferramentas de compilação de código de barras para arquitetura mips32 no meu WINince. Eu quero primeiro compilar um simples binário 'fatorial' para o meu roteador que é baseado no MIPS32. De pouca pesquisa na internet, descobri que é baseado no MIPS32 big-endian.
#cat /proc/cpuinfo

# cat /proc/version

O diretório LIB do roteador contém:

Eu tentei os seguintes parâmetros de compilação:
mips-linux-gnu-gcc -mips32 -muclibc -o factorial factorial.c Quando eu corri o binário de saída na caixa MIPS, ele apenas imprimiu "não é possível carregar a biblioteca 'libgcc_s.so.1'".
mips-linux-gnu-gcc -muclibc -mips32 -static-libgcc -s -o factorial factorial.c Quando eu executo sua saída, ela imprime 'sigsegv'.
O que está errado aqui? Qual parâmetro do compilador devo inserir? Por favor me ajude.
UPDATE : adicionada mais informações.
