[Mono-list] Crashes setting properties on DataGridView Column Headers?

Until 2.4 mono had an implementation that depends on polling. rt_sigsuspend is used by the GC machinery.

Please fill a bug report with a small test case that shows the difference. You can use the profiler we ship with mono to find the hotspots and point them on the bugreport.

No, mono-common will be in the dependency tree somewhere. Just
install the pieces you need and let the package manager do its magic.

If, after installing Mono, you can run apps using "./app.exe" instead
of "mono app.exe" then it's working. Note that the binary will need
to be executable ("chmod +x app.exe") before the first method has a
chance of working.

You'll need the core 2.0 framework libraries, as well as any others that your assembly depends on. It's not possible for us to extract that information from just the filename.

[Mono-list] Mono, PHP and .NET library on Ubunty Hardy?
I'm running a rails app and PHP at my SliceHost Ubuntu Hardy Heron vps
server. I've a PdfProcess.exe module built upon ASP.NET (.NET 2). I've one
PHP file which uses a passthru("PdfProcess.exe ..") function which loads
a pdf template and outputs a new processed pdf file and sent to browser. The
combination of PdfProcess.exe and PHP passthru(...) function works on my
Windows Apache/PHP server in my development system.
Now I got to use this in my Ubuntu Hardy. I googled on how to run a .NET app
using Mono in Ubuntu and I found http://mono-project.com/Main%5FPage Mono .
And I've been trying to install Mono 2.0.1, 2.2 since 2 days, still figuring
out the installation error and I'm getting no-where. So, before spending
anymore time on it I want to know what are the things to install to make
work the PHP passthru(...) function and PdfProcess.exe work together??
Only installing Mono will work or do I have to install XSP and MCS as well??
And which version of Mono is required to run this PdfProcess.exe .NET 2
based module??

Assuming by shared hosting you mean you only have FTP access, then if you find out what platform and system the server is running on, you could compile Mono on a comparable box (or virtual machine) with corresponding paths and try to misuse Mono as a CGI binary. ;) For anything else you either need support from the hosting provider or shell access on the webserver.

Because mono is huge, and they don't want to "waste" that much space for unused packages. For example, mono on openSUSE includes the 1.0 profile, which is split into separate packages on Debian & Ubuntu, and is NOT installed by default (as most apps don't need the 1.0 profile).
