[Mono-dev] Building a Mono RPM

2013-08-26 Thread Chris Tacke

Let me preface this with the fact that I’m pretty new to Linux.

I have pulled the Mono source and successfully built it on 32-bit Ubuntu.  I 
was able to successfully take the binaries generated from a “make install” and 
copy them to a different Linux distribution and actually run a Mono app on that 
target.  That seems like the wrong way to approach it though.  I suspect I 
should be distributing an RPM file.

So I decided to try to build the RPM file today, and I’m having very little 
success.  The first issue I had was that rpmbuild would give an “Unknown 
command: recommends” error.  So I went into the spec fiel and commented that 
line out, just to see where it went from there.  Now it complains that it can’t 
find mono-3.3.0-tar.bz2.  I can only assume that I need to generate this file, 
but I’m not sure exactly how.  Is there a script that will do it, or do I just 
tar up the installation?

Is there any documentation on how to build an RPM starting with just a clean OS 
build, or at least from a system where Mono has been compiled and installed?

Re: [Mono-dev] SGEN support when cross compiling

2013-08-26 Thread Bassam Tabbara

I tried that and I run into the following error when I run mono:

sgen is not supported when using --with-tls=pthread

Looking at the code here:

https://github.com/mono/mono/blob/master/mono/metadata/sgen-gc.h#L990

Seems like pthread is only supported on darwin and windows. I'm cross compiling 
to linux with with-tls=pthread.

sgen works fine on ARM and so does cross compiling to it.

Hi,

  It might be easier to compile on the device itself using distcc+a cross

I've fixed a few bugs with Mono (most around the ASP.NET routing
implementation) and I've found that the Mono developers are pretty good
with pull requests. If you do a good fix, it's very likely to make it into
a release of Mono. The 3.x series is having more frequent releases compared
to the 2.10.x series.

Almost the same thing just happened again. I got this error when calling

after "sudo service apache2 restart" everything continued to work properly.
Something causes the configuration to become messed up in (what looks 
like) random or heavy load situations and this makes everything go south.


Unfortunately it looks like this part of mono is not in the primary (or 
maybe in no) focus for the Xamarin team so my best bet here is to:
1. Use the open source way, find and fix it myself and hope that we will 
have this change in the official mono one day.
2. Move to a Windows server with IIS which I know is not a secondary 
focus for MS.

So probably WebServicesSection.Current.WsdlHelpGenerator.Href is 
returning null or 
ConfigurationManager.OpenMachineConfiguration().FilePath is returning 
null.


For the first case, as this is read from current configuration which 
can be reread from time to time as any part of the configuration 
chain changes it is possible that either some of those MonoTodos in 
https://github.com/mono/mono/blob/master/mcs/class/System.Web.Services/System.Web.Services.Configuration/WsdlHelpGeneratorElement.cs?source=cc are

[MonoTODO ("probably verifies the Href property here, after

protected override void DeserializeElement (XmlReader reader, bool

{
base.DeserializeElement (reader, serializeCollectionKey);

}
[MonoTODO]

protected override void Reset (ConfigurationElement parentElement)

{
base.Reset (parentElement);

}

or some locking is missing to avoid reading an incomplete current 
configuration instance...


As for the second case after much navigating through sources it comes 
down to calling an internal call 'string get_machine_config_path ()' 
which I don't have time now to try to explore...


Hope it helps,

Hey guys,

I have worked with mono for almost 7 years but I recently got
involved in a project that used mono web services and apache
together on Linux.

The problem is that as the load on the service started to rise we
started getting different errors which appear in random intervals.

One of the errors is described here:
https://bugzilla.novell.com/show_bug.cgi?id=522631 (not by me).
And attempting to fix it I added some configuration that caused
another error to appear once:
http://img577.imageshack.us/img577/4473/44in.png

The only common spot between the errors seem to be the
configuration. Looks like at some point it becomes invalid. This
sometimes happens after the service gets restarted, but sometimes
it happens while the service is running normally. A restart of
apache usually fixes the problem.

Does anybody else encountered something sim
