Box2d tests fail #90

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. make box2d
2.
3.

What is the expected output? What do you see instead?

I expect Box2d to build and test successfully. Instead I get the error message

What version of the product are you using? On what operating system?

I am running Debian Wheezy on a 64bit computer. I am trying to build the latest 
version of naclports with no success (I ran a gclient sync just now, which 
presumably updates everything, not that box2d has been changed recently). I am 
using the NaCl SDK for pepper 30

NACL_SDK_ROOT is set to /home/<user>/NaCl/nacl_sdk/pepper_30

Please provide any additional information below.

It appears that the signal 6 comes up no matter which library I try to build. 
For instance zlib gives this.

Could it be a problem with NaCl itself? naclsdk list shows

When I installed the SDK the last weekend, the install script pulled me version 
pepper_31 . What happens if you try to compile with that? Installing pepper_31 
as well and changing NACL_SDK_ROOT variable to point to it I mean.

The exact same thing happens with pepper 31.

We are not seeing this issue on the linux build machines:
http://build.chromium.org/p/client.nacl.ports/builders/linux-newlib-0/builds/466
/steps/x86_64%20newlib%20zlib/logs/stdio

I think that signal 6 is SIGABORT which is normally a signal sent from within 
the application (e.g. when malloc detects memory corruption).

Can you try a little debugging?  I would try the following:

1) cd out/repository/zlib-xxx/build-nacl-x86-64
2) edit the minizip script:
   - remove the initial line redirecting nacl logging to /dev/null
3) export NACLVERBOSITY=3
4) run ./minizip (pass the same args that the build.sh script does)

If that doesn't give you any more info, then edit the script again
and pass '-g'.  This will cause the sel_ldr to pause on startup so
you can attach a debugger.  You can then run "x86_64-nacl-gdb minizip.nexe"
and attach to the sel_ldr with "target remote  :4014".

For more information on debugging see: 
https://developers.google.com/native-client/devguide/devcycle/debugging

Also, if you want to build zlib (and minizip) with debugging symbols you can
export NACL_DEBUG=1 before building it.

There was no such directory, but I did find a script called minigzip inside the 
zlib-1.2.3 directory. Commenting out the second line and exporting 
NACLVERBOSITY=3 resulted in the following output.

Searching for the error message turned up another issue 
(https://code.google.com/p/nativeclient/issues/detail?id=1883) with the same 
error. However this was over two years ago and for ChromeOS, not Debian, so I'm 
not sure it helps.

I found these issues too, so it seems like it might be a problem on certain 
Linux distributions where /dev/shm is not mounted as executable. I'm just 
running plain Debian, so there shouldn't be anything fancy there. But the 
suggested fix of "sudo mount -o remount,exec /dev/shm", seems to have worked.

Closing this issue as it seems to be general NaCl issue, no naclports related.  
Please reopen if you disagree.
