I use cygwin on windows2000 server and I install arm-elf-gcc for cygwin. $ arm-elf-gcc -v Reading specs from /usr/local/cross-gcc/arm-elf//lib/gcc-lib/arm-elf/3.0/specs Configured with: ../gcc-3.0/configure= --prefix=3D/usr/local/cross-gcc/arm-elf/ --t arget=3Darm-elf --with-newlib --enable-multilib --with-gnu-as= --with-gnu-ld Thread model: single gcc version 3.0 when I link use arm-elf-gcc ,but it output nothing (neither error nor successful output) My command and result is: arm-elf-gcc -e _start -N -Tmy.link -nostdlib -Wl,--EB -o rom.bin abc.o timer.o abcd.o console.o p00.o kkk.o ... (with a lot of .o files) make: *** [rom.bin] Error 128 but when I use the same command in windows 2000 SERVER security mode with command line, arm-elf-gcc output correct result:it output rom.bin I think I maybe a error in gcc or make does anyone tell me how to solve this problem? ren donghua [EMAIL PROTECTED] 2002-07-16 nfzf)+-&jG+mj)`+Yb茄~螅
