QT "Compiler Setup" worked before. Why not now? Options

[ClintReese]

Hi.

History:
First, I followed the directions at this group for "Compiler Setup" under development how-to's on one of my PCs. With some time, effort, and help from other Linux users, they worked. It compiled the example application for the x86 and the arm. They both worked. The arm one worked on the Z. Then, I struggled with getting Linux connectivity set up. In the process, I recompiled so many kernels and reinstalled the OS so many times that I removed my old QT compiler setup. "That's ok," I thought. "I've recorded exactly what I did." With help from people on this group, my Linux connectivity now works.

However, when I do what I did the first time to get the compiler set up, it doesn't work this time. I've tried reinstalling the original OS I used and following the instructions 3 times. I seem to keep getting the same errors. Here are the steps I performed, copied from my screen:

OK, QT people, what did I not do these 3 times that I did the first time that I got it working? It worked before. These error messages indicate to me that the string.h header file can't be found, but you can see where redhat told me that the header file packages were installed. What is going on here?

My first thought is to give up on buying QT and try Squeak, but I don't know if Squeak will work in real-time.

Any ideas, anyone?

I neglected to mention my distribution and system information. The OS which I reinstalled 3 times was Red Hat 9. I got the CD's from "The Red Hat 9 Bible."

System information (with IP address erased):

[clint@xxxxxxxxxx clint]$ uname -a
Linux xxxxxxxxxx.com 2.4.20-8 #1 Thu Mar 13 17:18:24 EST 2003

Firstly, why are you running as root (other than for rpm)? Sounds dangerous to me.... anyway onwards:

Looks like this is the problem you're having with your x86 build

> stddef.h: No such file or directory

Possibly because you can't install the native version of GCC 2.95. I don't know how to make this work, sorry, I don't ever compile stuff for x86 so I'm not sure I even have a native GCC 2.95.

Try cross compiling the same thing and see whether that works. BTW you can't run 'make clean' if the Makefile doesn't still exist to tell 'make' what to do for 'clean'.

Thanks for the reply.

I'm running as root because I just reinstalled the OS 3 times, and typed what you see in the post. If I corrupted the system by typing something wrong in the post, I'll just reinstall the OS again. I didn't want the screen littered with "permission denied" when I posted. Thanks for the concern.

That's what it looked like to me too.

These dependencies for GCC are interesting, aren't they? Red Hat 9 ships with a version of GCC which supposedly won't work with the QT cross compiler. So, I just searched the internet for RPMs. The installed RPM's worked before, I think. Maybe I should just download the sources from GNU and learn how to install it manually?

Hehe. Yes, I knew that. But, I wanted to post EXACTLY what I typed after reinstalling the OS, so that there was no confusion

Thanks again for the fast reply Simon. Any other input from you is welcome, too. Does anyone else have any ideas?

I CAN'T explain why, I just know what worked for me.
I have Fedora Core 1 which is pretty much RedHat 9 as I understand it. I followed how-to's with all the gcc2.95 references and had several errors, but then found I DID NOT HAVE TO DO the backward compatible gcc rpms. Just used what came with default install of Fedora. Everything worked. Maybe this will give you a clue to your problem.

Thanks! That makes sense. Now that you mentioned it, I think that I did downloaded QT directly from Tolltech's site last time.

I intend to try it.

Thanks again!

Sorry for starting a new thread. I just found out that I should have looked under "Linux Issues" instead of QT/Qtopia. I should have looked under both before posting.

The second link which you gave describes EXACTLY the problems which I've been having. I'm just a month late.

I seem to be at the point where markb was when he was getting the errors about the JPEG stuff. Onward!

Anyway, thank you for posting so helpfully. I'll start posting on the right thread now, if I have trouble.
