Hi, I failed to compile gzip with my gcc, error log is here: sh-3.2# /usr/local/bin/powerpc-none-linux-gnuspe-gcc -std=gnu99 -DHAVE_CONFIG_H -I. -O2 -mcpu=8548 -mspe -mabi=spe -mhard-float -mfloat-gprs=double -MT utimens.o -MD -MP -MF .deps/utimens.Tpo -c -o utimens.o utimens.c utimens.c: In function 'gl_futimens': utimens.c:123: warning: implicit declaration of function 'futimesat' utimens.c:123: error: 'AT_FDCWD' undeclared (first use in this function) utimens.c:123: error: (Each undeclared identifier is reported only once utimens.c:123: error: for each function it appears in.) But after installing another "gcc" which was built to support java, this issue disappear. The difference between the two "gcc" is only "--enable-languages", the good gcc support java, but the bad one not. After investigation, I found that: 1. bad "gcc" uses "/usr/local/lib/gcc/powerpc-none-linux-gnuspe/4.3.2/include-fixed/featur es.h", which doesn't contain "__USE_ATFILE" 2. good "gcc" uses "/usr/include/features.h", which contains "__USE_ATFILE" My question is: 1. since there is /usr/include/features.h, why bad gcc select "/usr/local/lib/gcc/powerpc-none-linux-gnuspe/4.3.2/include-fixed/featur es.h"? 2. why bad gcc removed __USE_ATFILE when it was compiled without java? I don't know whether attachments are allowed(previous mail was sent, but didn't received), if needed, I can send out the preprocessed utimens.c. B.R. Harry
