I use CFLAGS="-O1" while executing configure
But I get below message
  CCLD   lttng-consumerd
/media/sdb2/toolchain/arm/arm-v7a8v4r3-20131011/bin/../lib/gcc/arm-v7a8v4r3-linux-gnueabi/4.7.4/../../../../arm-v7a8v4r3-linux-gnueabi/bin/ld:

../../../src/common/.libs/libconsumer.a: could not read symbols: Bad value
collect2: error: ld returned 1 exit status
make[3]: *** [lttng-consumerd] Error 1

is that related to optimization?

appreciate your help,
