don't fail fatally if qtrace can't be loaded
Helps with p9 public mambo on fedora at least
Fixes:
if { [file exists $env(LIB_DIR)/perf/qtrace.tcl] == 1} {
- source $env(LIB_DIR)/perf/qtrace.tcl
+ if { [catch {source $env(LIB_DIR)/perf/qtrace.tcl} issue ] } {
+ puts "QTrace not available: $issue"
+ }
proc start_qtrace { { qtfile qtrace.qt } } {
QTrace::Initialize p9 mysim
