Compiling OpenTTD for Raspberry Pi: help please

[HermitTurtle]

This is my first post to these forums so let's start off with a 'Hello world!'

Before getting in to the issue let me say I'm very new to linux. I ran a Mandrake webserver from my home some 15 years ago, and got along ok,
but haven't touched it since. That is until I picked up the Raspberry Pi, which was yesterday! So please, when explaining something, assume very
little beyond reading comprehension.

My setup
Raspberry Pi model B+
Raspbian / Wheezy
GCC 4.6

What I'm doing
I want to run the OpenTTD dedicated server on a Raspberry Pi.
I downloaded the source and combined the information from several tutorials (mainly: this one and this one) to compile it.
I installed a bunch of libraries, one of them manually cause the Raspbian repository didn't have an up to date version.
I've gotten to the point where I have what seems like a working binary but the compiler is still giving me some error messages.

The problem

When compiling the OpenTTD source I'm getting several errors:

[SRC] Compiling cpu.cpp
/home/openttd-workspace/openttd-1.4.3/src/cpu.cpp:74:2: warning: #warning "(non-fatal) No support for rdtsc(), you won't be able to profile with TIC/TOC" [-Wcpp]

I think this is because the Pi doesn't have a RealTimeClock. It says 'non-fatal', should I worry? If so, how can I fix it?

This is followed by about a page's worth of error messages just like it. I'll post the full compilation-output below. I tracked this issue down on google all the way in to the code and found the following comment:

00138 /* In case GCC warns about the following, see GCC's PR38509 why it is bogus. */
00139 free(p);

I'm not sure what that means. So again the question: should I worry? If so, how can I fix it?



I think those are all the problems I've run in to. In the end the compilation process did complete and produced what seems to be a working binairy.
But common sense dictates compilation errors can't be good, and hence I am here.

Thanks in advance for any help!

It's a shame no one replied!

Did you get it to work? How does it perform? Because I don't have a Raspberry Pi yet, but I had the same idea as you. Running an OpenTTD server on a Raspberry Pi!

[HermitTurtle]

Yes, despite the errors during compiling, the binary seems to work fine. The performance seemed to be fine as well, though I didn't get a chance to test it with more than 4 players.

Give it a shot Robstar. If nothing else it's a fun little project

The point is: there is no error. All I see are compiler warnings.

Additionally, those warnings are issued without reason - as explained by the OpenTTD code comment which you uncovered yourself. the referenced bug in GCC now here linked for you:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=38509
http://gcc.1065356.n5.nabble.com/PATCH- ... 19327.html
This bug was fixed in gcc 4.7 and you're using gcc 4.6 which still exhibits this bug.

[HermitTurtle]

Thanks for clearing that up Planetmaker

This was the first time I ever tried to compile anything myself. All I saw was the compiler complaining about something I didn't fully understand.

I'll see if I can upgrade Raspbian's GCC to 4.7 and try again.

I think this is because the Pi doesn't have a RealTimeClock. It says 'non-fatal', should I worry? If so, how can I fix it?

No need to worry unless you want to do some profiling.
