Hello,
I'm trying to use gperftools to profile the Chapel code, but simply link
the profiler library doesn't produce the profile file, so I need to
explicitly call two external C functions within my Chapel code, here's what
I did:
1. in my chapel module:
extern proc ProfilerStart(name: c_string);
**it suggested me to use c_string instead of string
exetern proc ProfilerStop();
then in proc main, I called this two functions
2. recompile my chapel program:
chpl -g myCode.chpl -I../include/ -o myCode -L../lib -ltest
But I got this error :
/_main.c:30:0:
/Hui.c: In function ‘chpl_user_main’:
/Hui.c:160:1: error: implicit declaration of function ‘ProfilerStart’
[-Werror=implicit-function-declaration]
/Hui.c:160:1: error: nested extern declaration of ‘ProfilerStart’
[-Werror=nested-externs]
/Hui.c:163:1: error: implicit declaration of function ‘ProfilerStop’
[-Werror=implicit-function-declaration]
/Hui.c:163:1: error: nested extern declaration of ‘ProfilerStop’
[-Werror=nested-externs]
cc1: all warnings being treated as errors
make: *** [/tmp/chpl-hzhang86-15966.deleteme/experiment.work.funh.tmp]
Error 1
error: compiling generated source [mysystem.cpp:43]
Should I just ignore these warnings ? but how to disable this warning as
error option?
Or am I doing it wrong ?
Thanks
