Have you installed the “devtoolset-1.1”?

By the way, which component of SPDK are you trying to enable on the old linux kernel 2.6.32 here?

Have you checked whether scl can work? If it is workable, the scl-utils-build may be not required.

I can install scl-utils now, but for scl-utils-build,  I could not
#yum install scl-utils scl-utils-build -b current
Loaded plugins: bestyumcache, branch, fastestmirror, security
Loading mirror speeds from cached hostfile
Setting up Install Process
Package scl-utils-20120927-9.el5.x86_64 already installed and latest version
No package scl-utils-build available.
Nothing to do

Could you tell me where I could go to download this scl-utils-build?
 Great Thanks

Hi Pan,

Try below command before running the “make” command:

scl enable devtoolset-1.1 bash

You may replace "bash" with their preferred shell.

Thanks,
Gang

Hi All,

I met an error when I tried to compile spdk under linux kernel 2.6.32, and gcc version is 4.9.2:
$make DPDK_DIR=../dpdk/build/
  CC lib/bdev/bdev.o
bdev.c:1: error: bad value (native) for -march= switch
bdev.c:1: error: bad value (native) for -mtune= switch
make[2]: *** [bdev.o] Error 1
make[1]: *** [bdev] Error 2
make: *** [lib] Error 2
bdev.c:1: error: bad value (native) for -march= switch

Could you give me some help?

Thanks very much!
Pan
