- - UCPP Error (http://www.chiefdelphi.com/forums/showthread.php?t=98930)

Hi, I'm having some problems with the ucpp project. I'm running arch linux, with wine version 1.3.35 and no programs installed into it except for whatever ucpp did. Here's what I did:

I downloaded the zip file from https://github.com/nikitakit/ucpp, unzipped it, then moved it to /home/adam I added /home/adam/ucpp/ucpp to my path, installed wine and wine_gecko (using pacman), then went to the directory where my c++ project is. There are three header files, two with constants and one is the header file for main, and main.cpp; and two directories with other classes. I typed:

Code:

$ ucpp setup -t 3238

$ ucpp configure

and got an error about bash not recognizing commands in ucpp_gen_makefile.py, so I added

Code:

#! /usr/bin/env python2

to the top of both that file and the gen_wpilib_makefile file.
I ran

Code:

$ ucpp configure

with no errors, and then I ran

Code:

$ make

which outputted the normal things that make does ("building... "), but an error message window popped up and said that nmppc had a serious error and crashed. On the terminal window, the error was:

Code:

make: built targets of /home/adam/team3238/2011robotcode/cpp/2011-12-19-0/PPC603gnu

A few seconds later, after the next prompt had showed up, I got another error message:

Code:

err:ntdll:RtlDeleteResource Deleting active MRSW lock (0x111f64), expect failure

The first problem shows up only when everything compiles with no errors (it shows up when there are warnings though). It doesn't show up when everything is already compiled (ie make doesn't do anything). The second problem appears to show up randomly.

Since I don't have a cRIO handy, I'm not sure if this is actually affecting the outputted code or the deploy function.

Hopefully I can get an answer to what the problem is or help the developer fix something.

Can you post the code that you were building?

My guess is that Wine had a regression. Can you try another version of Wine?

Keep this thread up to date, and we/I will do our best to help. If you are having problems, then it isn't perfect yet.

Here's the code. It has a few warnings, sorry about that. I'll see if I can downgrade, but it would be pretty tricky.

Let me start with the doozey. Not a make export, and defiantly not a wine expert.

Now here is what I think

almost all of that is a wine error, thanks to some googling and and a ubuntu forumhttp://ubuntuforums.org/showthread.php?t=820855(the section where they examine an error similar to yours is near the bottom of the page). I dont know if that is correct but seems like a reasonable answer. Sifting through the memory address I do see that it tries to call Windriver file, and would lead me to ask is Windriver installed? Based on the ubuntu forum I would wonder if that is the issue. a casual glance through you code brought no gapping errors to my attention.

ucpp installs the compiler suite for Windriver automatically from a set of tools that NI puts out for free on their website. (Don't have the link handy, but you can read it from the source.) This smells like a wine regression to me, or a bug in nmppc triggered by something odd happening in wine.

It may take a day or so for me to poke at it, but I'll try my best to get back to you. (PM me or something if I forget...)

Just thought that it may be useful to try compiling my code on the "real" windriver and comparing it to what compiled on my machine and see if they're the same file.

Windriver itself is not installed; I'm running linux and have never put the DVD in. However, it may be that I tried to remove and redownload ucpp several times. When I did that, I would remove the downloaded ucpp folder and ~/.ucpp, plus whatever extra stuff was put in the project's directory -- is there another place that could be conflicting?

Thank you!

EDIT: Downgrading wine to 1.3.8 seemed to have fixed the problem. I assume you'll want to submit a bug report to the wine developers

Glad to hear it!

The regression still exists in wine 1.4

With the lastest version of ucpp and wine, everything compiles successfully and I get no errors (and I don't have to modify the files I said in the last post). I have not tried downloading code to a robot, though.

Thanks for all your hard work! It's great to even check for syntax errors without getting errors about "CANJaguar is not a type"
