hi you, i use mips-linux-gnu-gcc 4.3.2 (Sourcery G++ Lite 4.3-51) and glibc 2.12.1-0ubuntu9 (libc6-dev) but when i build it error is: make ARCH=mips CROSS_COMPILE=mips-linux-gnu- http://old.nabble.com/file/p30366623/thientai.png CHK include/linux/version.h CHK include/linux/utsrelease.h CC arch/mips/kernel/asm-offsets.s arch/mips/kernel/asm-offsets.c: In function 'output_mm_defines': arch/mips/kernel/asm-offsets.c:232: error: invalid 'asm': invalid use of '%X' arch/mips/kernel/asm-offsets.c:233: error: invalid 'asm': invalid use of '%X' arch/mips/kernel/asm-offsets.c:234: error: invalid 'asm': invalid use of '%X' make[1]: *** [arch/mips/kernel/asm-offsets.s] Error 1 make: *** [prepare0] Error 2 http://ngosylien.edu.vn/forum/showthread.php?482-3-12-2010-Port-Gcc-for-Mips-to-Gcc-for-x86&p=589&viewfull=1#post589 hjksfw hjksfw wrote: > > Thanks very much. > I change glibc from 2.4 to 2.7 and the resulted cross-compiled > mips-linux-gcc 4.3.1 worked well for both kernel and dynamically > linked elf executables. > > å 08-9-3ïDavid Daney<ddaney@xxxxxxxxxx> åéï >> hjksfw hjksfw wrote: >> > Hi all, I have build mips-linux-gcc on debian i486 pc from following >> sources: >> > Gcc-4.3.1 >> > Binutils-2.18 >> > Glibc-2.4 >> > Kernel-headers-2.6.18 >> . >> . >> . >> > when I compile linux-2.6.18 from mips-linux-gcc 4.3.1, there is an >> error: >> > >> . >> . >> . >> > >> > the kernel compiled successfully.But mips-linux-gcc-4.1.1 have no such >> problem. >> >> Perhaps you should stick to gcc-4.1.1 for your kernel. >> >> > And the following is problems for dynamically linked elf. >> > A simplest test program: >> > #include >> > int main() >> > { >> > printf("hello mips\n"); >> > return 0; >> > } >> > >> > >> > mips-linux-gcc test.c ïo test-dyn >> > Mips-linux-gcc test.c ïo test-static ïstatic >> > >> > >> > $ file ./test-dyn >> > ./test-dyn: ELF 32-bit MSB MIPS64 executable, MIPS, version 1 (SYSV), >> > for GNU/Linux 2.0.0, dynamically linked (uses shared libs), not >> > stripped >> > $ file ./test-static >> > ./test-static: ELF 32-bit MSB MIPS64 executable, MIPS, version 1 >> > (SYSV), for GNU/Linux 2.0.0, statically linked, not stripped >> > >> > The strace results on the target mips board are following,(strace is >> > statically linked, so it can be executed): >> > Strace the program: >> > / # strace ./test-dyn >> > execve("./test-dyn", ["./test-dyn"], [/* 6 vars */]) = 0 >> > do_page_fault() #2: sending SIGSEGV to test-dyn for invalid read >> access from >> > 0002e258 (epc == 2aabf140, ra == 2aab4f70) >> > uname({sys="Linux", node="192.168.172.44", ...}) = 0 >> > old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, >> > -1, 0) = 0x2aac5000 >> > access("/etc/ld.so.preload", R_OK) = 0 >> > open("/etc/ld.so.preload", O_RDONLY) = 3 >> > fstat64(3, {st_mode=S_IFREG|0644, st_size=0, ...}) = 0 >> > close(3) = 0 >> > --- SIGSEGV (Segmentation fault) @ 0 (0) --- >> > +++ killed by SIGSEGV +++ >> > Process 98 detached >> > / # strace ./test-static >> > execve("./test-static", ["./test-static"], [/* 6 vars */]) = 0 >> > svr4_syscall() = 4122 >> > svr4_syscall() = 4045 >> > brk(0x494c98) = 0x494c98 >> > set_thread_area(0x49b460) = -2143376080 >> > brk(0x4b5c98) = 0x4b5c98 >> > brk(0x4b6000) = 0x4b6000 >> > fstat64(1, {st_mode=S_IFCHR|0646, st_rdev=makedev(5, 1), ...}) = 0 >> > ioctl(1, TIOCNXCL, {B115200 opost isig icanon echo ...}) = 0 >> > old_mmap(NULL, 131072, PROT_READ|PROT_WRITE, >> > MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2aaa8000 >> > write(1, "hello mips\n", 11hello mips >> > ) = 11 >> > exit_group(0) = ? >> > Process 100 detached >> > >> > I don't know what's wrong with the mips-linux-gcc 4.3.1, would you >> > help me please? >> >> I don't think gcc-4.3.x is supported by any version of glibc prior to >> 2.8.
