Thread: DTrace compiler warnings

DTrace compiler warnings

From
Bernd Helmle

I'm just seeing these kind of compiler warnings in current HEAD:

pgstat.c: In function ‘pgstat_report_activity’:
pgstat.c:2276: warning: passing argument 1 of
‘__dtrace_probe$postgresql$statement__status$v1$63686172202a’ discards
qualifiers from pointer target type

There are more of them (e.g. postgres.c), all passing a const char pointer.

Platform is Snow Leopard, 10.6.2, gcc 4.2.1

Hmm, const is also problem on solaris. dtrace generates probe.h file and
eats const. It generates following noise on solaris build:

"postgres.c", line 554: warning: argument #1 is incompatible with
prototype:prototype: pointer to char : "../../../src/include/utils/probes.h",
line 582argument : pointer to const char

IIRC, it was discussed. I cc Robert. He should know answer why const is
ignored.

Have you dug into this further?
