‘make gcc elf2flt gdb-host’error in nios2-linux-20120802

Honored Contributor II

Hi, everyone!  

I have download the files of the nios2-linux-20120802 


There's no errors! Then extra the nios2gcc-20080203.tgz to the 'home/nios2-linux/toolchain-build/build/nios2/bin' 


nios2-linux-uclibc-gcc -v 

# nios2-linux-uclibc-gcc -v Reading specs from /home/nios2-linux/toolchain-build/build/nios2/lib/gcc/nios2-linux-uclibc/3.4.6/specs Configured with: /home/nios2-linux/toolchain-build/../gcc3/configure --prefix=/home/nios2-linux/toolchain-build/build/nios2 --target=nios2-linux-uclibc --enable-languages=c --with-sysroot=/home/nios2-linux/toolchain-build/build/sysroot/ --disable-__cxa_atexit --enable-target-optspace --with-gnu-ld --disable-shared --disable-nls --enable-threads --enable-multilib --enable-cxx-flags=-static Thread model: posix gcc version 3.4.6

I have never faced these problems in the nios2-linux-20100602,but I faced it in  

the nios2-linux-20120802 under the CentOS 5.6. 

The error occured when I input the command 

cd toolchain-build gcc --version git clean -f -x -d # clean on restart make gcc elf2flt gdb-host  

by following the URL: 

make: Entering directory `/home/nios2-linux/uClibc' make: `conf' is up to date. CC libpthread/linuxthreads.old/wrapsyscall.o libpthread/linuxthreads.old/wrapsyscall.c:101: error: redefinition of 'msync' ./include/sys/mman.h:97: error: previous definition of 'msync' was here make: *** Error 1 make: Leaving directory `/home/nios2-linux/uClibc' make: *** Error 2 #
