>Description:
After about two weeks of being harrassed by a programmer on one of
my boxes, I started to dig into it myself. He's been trying to use
gprof and the profiling stuff (built with gcc -pg), and its been
giving him the error:
cc -pg -g -O -Iinclude -Imodules -Lmodules grammar.o coldcc.o
[..lots of objects..] shs.o crypt.o -lm -o coldcc
ld: -lc_p: no match
*** Error code 1
A few frustrating hours later I finally figured out the problem is I
didn't install the 'Profiling Libraries' when I did the base OS
install/upgrade. This is a problem, because none of the docs on
gprof, or cc -pg, or anywhere else say they need to be installed (and
infact I only barely remembered seeing the option in the installer).
>How-To-Repeat:
Just install an OS without the profiled libraries, then try to compile
and link some code using the -pg option.
>Fix:
This is a serious frustration factor... IMHO, one of two things needs to
be done:
1) update the man page on anything regarding profiling to say in
big letters that 'this will not work unless the profiling
libraries are installed'
2) pull all profiling commands out of the base install and wrap
them in with proflibs as a generic 'Code Profiling Libraries
and Utilities' module, and change it so cc -pg will error out
if they are not installed (rather than simply dying with an
error of not being able to find libc_p).
