2)lttctl 0.64
3) lttv-0.12.10

cross compiled it for mips

my config option are CONFIG_LTT=y
CONFIG_LTT_FILTER=y
CONFIG_LTT_TRACEPROBES=y
# CONFIG_HAVE_LTT_DUMP_TABLES is not set
CONFIG_LTT_RELAY_ALLOC=y
CONFIG_LTT_RELAY=y
# CONFIG_LTT_RELAY_LOCKED is not set
# CONFIG_LTT_RELAY_CHECK_RANDOM_ACCESS is not set
CONFIG_LTT_SERIALIZE=y
CONFIG_LTT_MARKER_CONTROL=y
CONFIG_LTT_TRACER=y
CONFIG_LTT_ALIGNMENT=y
CONFIG_LTT_DEBUG_EVENT_SIZE=y
CONFIG_LTT_USERSPACE_EVENT=y
CONFIG_LTT_VMCORE=y
CONFIG_LTT_NETLINK_CONTROL=y
CONFIG_LTT_TRACE_CONTROL=y
CONFIG_LTT_STATEDUMP=y

now
ltt-armall
lttctl os running fine

but when i do
lttv -m textDump -t /tmp/trace1
The input data file /var/tmp/trace1/metadata_0 does not contain a trace
The input data file /var/tmp/trace1/block_0 does not contain a trace

tf->num_blocks)
/bin/lttv: line 15:   100 Aborted                 $0.real $*

this output is coming
so i checked /tmp/trace1 file , then i found the files are having 0 size
