Compiler flags

[spasmous]

Can someone point me to a website that lists the compiler flags for the
Linux c++ compiler. Yes, I know it's called c++ but I am using it to
compile .c files.

There's a chap called Google who can be contacted at
http://www.google.com - he knows all about that sort of thing.

That's like claiming that Mr Yellow Pages knows all about how to clean
drains, bake bread, drive taxis, and issue passports.

Google is a search engine, not an oracle. It doesn't know anything about
Linux, C++, or compiler flags. In fact, it knows little more than which
words appear on which Web sites. An intelligent Googler is well aware that
there is an awful lot of misinformation on the Web, for which Google cannot
reasonably be held responsible. Caveat surfer.

<OT>
The usual default compiler on Linux is gcc (it's actually a collection
of compilers for several languages, with a shared backend). There's a
command called "g++" that invokes it as a C compiler. Typically "cc"
and "c++" are installed as aliases for "gcc" and "g++", respectively.

If you want to compile C code, use a C compiler: either "gcc" or "cc",
not "g++", or "c++".

All this is explained in gcc documentation, which you can see by
typing "info gcc" or by doing a Google search for "gcc documentation".
</OT>

If you have any more questions about gcc (that aren't answered by the
documentation), try gnu.gcc.help. If you have questions about Linux,
try one of the many Linux newsgroups, or perhaps comp.unix.progr ammer.
If you have questions about the C language itself, this is the right
place.

We must do something. This is something. Therefore, we must do this.

You should learn to read the documentation.

Just write:

info gcc
or
man gcc

and the associated documentation will tell you ALL compiler
flags, and what they do.

Thanks - I didn't realize c++ was an alias of gcc. Sometimes, you know,
you have to compile someone else's programs on a platform that you
don't know. man c++ was my first try, then google on Linux c++ compiler
flags. Neither produced anything obviously useful.

Next was look for the group with most hits on my google search and post
there. Which is what I did. Sorry your NG is not pure enough for you
guys - but thank you for your suggestions.

Assuming you mean gcc, the appropriate flags are here (from Richard
Heathfield at some point in the past):
gcc -W -Wall -ansi -pedantic -Wformat-nonliteral -Wcast-align
-Wpointer-arith -Wbad-function-cast -Wmissing-prototypes
-Wstrict-prototypes -Wmissing-declarations -Winline -Wundef
-Wnested-externs -Wcast-qual -Wshadow -Wconversion -Wwrite-strings
-Wno-conversion -O3

Jacob Navia recommends adding -Wextra for the latest version of gcc.

Rather unfortunately, you have to fix the spacing yourself.

-Wextra is a newer name for -W. "info gcc" for details.

No, this set is from "those who know me have no need of my name" - all I did
was pinch it. (And he's been looking for it ever since.)

Here is my set, implemented via an alias:

-W -Wall -ansi -pedantic -Wwrite-strings -Wfloat-equal -gstabs+ -O1
