Re: Foundation-Linux i386 barfs on build- pthread and NSZombieObject?

Ahh...seems I better do this stuff first?

Hi all,

Been having great success with Cocotron,building stuff for windows, want to try Linux. Foundation keeps giving an error on build, NSZombieObject can't find <pthread.h> and subsequent errors because of this. pthread.h is in the Windows build headers but not in the Linux build ones. Am I missing something? Looked around to do due diligence, Using XCode 4.6, turned "Find Implicit Dependencies" off as per Chris' instructions.

Thanks for any and all.

That link is a *great* resource--yes, if there is anything in those instructions that you haven't yet done, then that's most likely the issue. The only change I see is that InstallCDT is now included with the Cocotron source, so you needn't download it separately.

[Dave Sopchak]

I tried moving the files over from a flash disk boot of Ubuntu 12.10, some of the lib files were not there, replaced by links...I tried doing the linky thing once things were moved over. 

Ran ./install.sh Linux i386 from the InstallCDT (I already have cocotron windows install working fine) and make gave me the following below errors

Is it better to toss Developer/Cocotron folder and start from scratch? Also, I'm doing an install of Ubuntu and will see if the files I need to move have changed, maybe they were a little on the light side for the flash drive boot. I didn't want to install unless I was sure I could compile this stuff.

Thanks for any and all, and I'll post my progress or lack thereof.

Hi all,

Looked at the cocotron page:

http://www.cocotron.org/Tools/Platform_Interface/?path=Tools/Platform_Interface

where Chris sez to put /usr/include in as well, this got me further, but updating XCode 4.6 tools and a reboot (suggested remedies) didn't get me any further, it barfs on

More detail below. I'm kind of clueless at this point. Any help greatly appreciated.

[Luca Lutterotti]

If you check the config.log you will see the problem will be probably due to one of the include file not found. The problem can be that you have some symlink not set or not working, in particular for the gnu, the sys, asm or other.
Try the following:
- delete the folder /Developer/Cocotron/1.0/Linux
- go to /Developer/Cocotron/1.0/PlatformInterfaces/i386-ubuntu-linux/include
- if the folders gnu, bits, sys, asm are present, delete them or rename to something like yyy_or
- create the following symlinks:
ln -s i386-linux-gnu/asm asm
ln -s i386-linux-gnu/gnu gnu
ln -s i386-linux-gnu/bits bits
ln -s i386-linux-gnu/sys sys

these should be the correct include paths. Start again the install.sh Linux i386

Hope it works, it did for me as the I had to recreate all the symlinks also in the lib.

I believe the problem is that /lib/cpp doesn't exist anymore on OS X. I think the quickest way to fix it is just symlink /lib to /usr/bin/, where cpp actually resides.

[andyvn22]

Also--I've never had any trouble with re-running the install script after (many) failures, so I doubt any of your problems would require starting from scratch.

Building the platform interface is always a little difficult, but worth it--keep at it!

[Dave Sopchak]

Hi Luca!

Thanks a lot. Looks like your trick got me farther:

/Developer/Cocotron/1.0/Linux/i386/gcc-4.3.1/i386-ubuntu-linux/bin/ld: cannot find /lib/i386-linux-gnu/ld-linux.so.2

collect2: ld returned 1 exit status

make[2]: *** [libgcc_s.so] Error 1

make[1]: *** [all-target-libgcc] Error 2

make: *** [all] Error 2

I'll see if I can put in another link and fix this,but the errors are getting to the point where I think I can understand them ;)

[Dave Sopchak]

Luca,

BTW, I didn't have any gnu, bits, sys or asm folders. I put in your sym links. I re-did all my sym links as well in /lib, and thought they worked- here's how ls -l lists the one in question:

-rwxr-xr-x  1 dave  admin   134376 Feb 15 09:50 ld-2.15.so

lrwxr-xr-x  1 dave  admin       10 Feb 15 09:55 ld-linux.so.2 -> ld-2.15.so

...kind of makes me wonder if I should create a link to /lib in /lib: ln -s  lib/i386-linux-gnu i386-linux-gnu

..but couldn't that cause some recursion trouble? I need to think about this some more.

[Dave Sopchak]

Hi Andy,

Thanks for your reply. Are you saying I should put a link to /usr/bin (root level) on my machine in the /lib folder in platformInterfaces in linux in Cocotron? I'm not the greatest with links at the moment, but I'm willing to learn.

Dave

[andyvn22]

I'm saying that the cpp "sanity" issue can be caused by a complete failure to find the file--check to see if /lib/ (root level) exists at all on your machine. If it doesn't, and you run into that same cpp-related "sanity check" error, then (from root level) ln -s /usr/bin lib is a quick hack to make sure that when the script goes looking for /lib/cpp, it finds /usr/bin/cpp, which actually exists. (This is a problem I ran into on newer versions of OS X. If *your* /lib/cpp already exists, or if you never run into that "sanity check" error message again, then lucky you!)

[Dave Sopchak]

Hi Andy,

thanks. Yes, I have /usr/bin. I'll give it a try! Thanks for the clarification.

[Dave Sopchak]

Hi folks,

After following Luca's and Andy's advice and putting in some sym links in, along with another of my own which allowed the install.sh to complete:

ln -s

/Developer/Cocotron/1.0/PlatformInterfaces/i386-ubuntu-linux/include/i386-linux-gnu /usr/lib/i386-linux-gnu

...whether or not this is correct it allowed the CDT tools install to complete for Linux i386.

Now I'm back to trying to build Foundation, and it gives me the same error-

/Users/dave/Projects/cocotron/Foundation/NSObject/NSZombieObject.m:13: Pthread.h: No such file or directory

If I put in a specific path to pthread.h like

#include "/Developer/Cocotron/1.0/Linux/i386/gcc-4.3.1/i386-ubuntu-linux/include/pthread.h"

it will take this but gives me a million other "cant find xxx.h" errors, so am I specifying the wrong search path?

Closer than ever...thanks for any advice.

Dave
