[Dev-C++] compiler options

[Site R. <sit...@fl...>]

hi,

  I don't know if this is a known bug, or not. If I go to tools - =
compiler options, and go to the settings tab, or similarly if I go to =
project options and click on the compiler tab, you see that list there =
with a few options, like


C compiler
C++ compiler
code generation
...


Well in any of those, if I try to change the option, I get a message =
that there was an attempted access to memory at some address, that =
wasn't allowed. For instance, if I go down to either (I forget which) =
the third or fourth item down, where it says "generate profiling =
information", right now it says "Yes". If I try to write "No" in there, =
it gives me that error. It does that for any of the options.


This would not bother me, but I don't want profiling information, and I =
have no way to change that.

Hi, 

Could someone tell me what are the compiler options "optimize", "best 
optimization", " a number of minor optimizations" do (dev-c++)? 

Thanks

They set the options -O1, -O2, -O3 and -fexpensive-optimizations when 
calling gcc.
Go read the onlinedocs from gcc.gnu.org.

Hint: use Google. This search sring is useful: "site:gcc.gnu.org 
onlinedocs thestringyouwanttosearch"


PS: the -O3 seems to be broken in MinGW/GCC 3.3.1. The last GTK+ binary 
release had to be recompiled with -O2 because of this.
