[Ironpython-users] Changing the version information of ironpython .dll assembly

Tue Feb 16 05:08:21 EST 2016

Thank you Andrew.

I am not a programmer so sometimes obvious things to try are not really something I know how to do.

Yes, I installed my IronPython 2.7 from .msi.

I changed the location of the pythonDll.dll file. I copied it into the IronPython installation folder, like so:

C:\>"D:\Program Files\Microsoft\ILMerge\ILMerge.exe" "C:\Program Files\IronPytho
n 2.7\pythonDll.dll" /ver:1.2.3.4 /out:"C:\Program Files\IronPython 2.7\pythonDl
l2.dll"

Now the previous error message disappeared. This one:

Unresolved assembly reference not allowed: IronPython.

But a new error message appeared:

An exception occurred during merging:
Unresolved assembly reference not allowed: System.Core.

   at ILMerging.ILMerge.Merge()
   at ILMerging.ILMerge.Main(String[] args)

I tried googling, and found this topic which describes the same error message:

http://stevemichelotti.com/ilmerge-unresolved-assembly-reference-not-allowed-system/

Indeed I have the same .NET version, like in that topic: 4.0.30319

I created the ILMerge.exe.config file in the same folder where ILMerge.exe is:

<configuration>
    <startup useLegacyV2RuntimeActivationPolicy="true">
        <requiredRuntime safemode="true" imageVersion="v4.0.30319" version="v4.0.30319"/>
    </startup>
</configuration>

Now when I run the ILMerge.exe from the command line, the following error message appears:

Process is terminated due to StackOverflowException

Any suggestions on what to do?

Thank you.
Didier.

This is the error message I got:
An exception occurred during merging:

I always try something before suggesting it and it worked fine for me when I tried it on a dll I made with clr.CompileModules. Are your IronPython dlls in the GAC? i.e is IronPython installed from the msi? The only thing I can think of is that IronPython.dll is not accessible for some reason.

Thank you for the replies both Andy and Slide.

@ Slide:

I am currently bound to use ironpython 2.7.

Can you provide a link or an explanation for this part please:

       "You could also compile from the 2.7 mainy branch and get it from there. Ipyc replaces pyc.py."

@ Andy Graham:

I downloaded the ILMerge utility v2.12.0803<https://www.microsoft.com/en-us/download/confirmation.aspx?id=17630> and tried to use the same syntax you gave me:

C:\>"D:\Program Files\Microsoft\ILMerge\ILMe

rge.exe" D:\dlls\pythonDll.dll /ver:1.2.3.4 /out:D:\dlls\pythonDll2.dll

You can do this now with ipyc, which should be in the next version. It allows you to set many more things than pyc.py. You could also compile from the 2.7 mainy branch and get it from there. Ipyc replaces pyc.py.

Thanks

ilmerge mycode.dll /ver:1.2.3.4 /out:mycode.dll

ILMerge is available via NuGet in Visual Studio or from the Microsoft Download center

http://www.microsoft.com/en-gb/download/details.aspx?id=17630

Last time I looked the

version on NuGet is 2.14.1208 while the download is the earlier version 2.12.0803.

Subject: [Ironpython-users] Changing the version information of ironpython .dll assembly

Hello,

I have the following issue with ironpython 2.7: I would like to compiles the .py file to .dll. Here is a nice example<http://blogs.msdn.com/b/srivatsn/archive/2008/08/06/static-compilation-of-ironpython-scripts.aspx> on how this can be done with clr.CompileModules method.
The problem is that the File Version of the compiled .dll is always: 0.0.0.0.

How can I change that?
I posted a question about this issue on stackoverflow.com<http://stackoverflow.com/questions/35073738/changing-the-version-information-of-ironpython-dll-assembly>. Even there there stands that the issue is solved, it isn't. the person who tried to help me (D. Alveno) really gave a lot of effort to do that. So this is why I marked his answer as the solving one. But in reality the issue is still not solved.

D. Alveno suggested using ipy.exe pyc.py<http://stackoverflow.com/a/35137830/3137724> instead of clr.CompileModules method. In the end this again resulted in getting a .dll file with File Version: 0.0.0.0.

I also tried a couple of other methods (those three ones mentioned on stackoverflow.com<http://stackoverflow.com/questions/35073738/changing-the-version-information-of-ironpython-dll-assembly>), but all of them failed, as they do not seem to be made for ironpython .dll assemblies, but probably C# and VB.NET<http://VB.NET>.

I would welcome any kind of advice.

Thank you in advance.

With kind regards,
Didier Bernard
