Win10 VS2015 syntax error at token '.field' in: .field static assembly initonly int64 [reopen] #220

chunyisong · 2016-05-27T02:16:34Z

Hi，it raises errors when i rebuild clrmodule.The build env and config is :
window10 Visual Studio 2015 , Release Win x86 , add "PYTHON35, UCS2" compilation symbols to both Python.Runtime and clrmodule projects
The error is:

I don't know much about C# and visual studio.Thank you very much for helping solving this problem.

chunyisong · 2016-05-27T02:19:46Z

I find the same issue #216 ,so close this .

den-run-ai · 2016-05-27T02:55:56Z

@chunyisong you can install PyPi wheels (pip install pythonnet), any reason why you need to recompile the source code locally?

Please re-open this issue, since your error is different from #216:

error : syntax error at token '.field' in: .field static assembly initonly int64

Next is did you add PYTHON35 compilation flag to both Python.Runtime and clrmodule projects? Right now you have to do this manually.

chunyisong · 2016-05-27T03:28:28Z

@denfromufa I add "PYTHON35, UCS2" compilation symbols to both Python.Runtime and clrmodule projects ,but same errors occur！
Now I am using pythonnet-2.1.0-cp35-cp35m-win32.whl from PyPi，but I want to build pythonnet myself。I don't kown much about C# and VS,so I wish someoen help solve the problem.
Thanks for help and for the pythonnet project!
I reopen the issue.

den-run-ai · 2016-05-27T03:36:05Z

@chunyisong can you try to update unmanaged exports to 1.2.7?

see here:

#206

also can you try to build pythonnet from python side (not in Visual Studio), see instructions here:

python.exe setup.py bdist_wheel

https://github.com/denfromufa/pythonnet/wiki/Troubleshooting-FAQ

den-run-ai · 2016-05-27T04:15:11Z

i tried building on windows 10, vs 2015 pro update 1, python35, release x86 and I do not get your error!

So please report: exact windows build number, vs 2015 full version number and license type (community, pro, express, etc.), .NET version.

chunyisong · 2016-05-27T06:23:36Z

@denfromufa
I update unmanaged exports to 1.2.7.In addition, I find 1.2.7 can work if I replace "UnmanagedExports.1.2.6" with "UnmanagedExports.1.2.7" in file clrmdule/clrmodule.csproj .Then I rebuild and get "syntax error at token '.field' " .The output is:

Ok, let me try with .net 4.6, did you actually change python project
settings from .NET 4.0 to 4.6?

Also I need to upgrade my VS 2015 to Update 2, not sure if enterprise
edition matters.

In the meantime, can you uninstall MSVC Compiler for Python 2.7 and try
again? Your VS 2015 already includes C compiler and mt.exe.

@denfromufa Actually my python project target framework settings is .NET Framework 4.
I will not use higher .net version if it is possible.

clmodule.il should not be used anymore in the build process. This is stated in comments for clrmodule projecy. Now unmanaged exports is automagically generating clrmodule.il and compiling to clr.pyd, but this is failing on you badly.

den-run-ai · 2016-05-27T20:51:09Z

I tried upgrading to VS 2015 Update 2 (not Enterprise, but Professional) on
Windows 10, and still do not see your error. Everything builds fine!

So do you mind installing git, add it to your %path% env. var. and try:

pip install git+https://github.com/pythonnet/pythonnet

I wonder if something is wrong with the source code that you downloaded.

@denfromufa I'm sorry for late to response.I try two works this weekend as follows:

First, I install pythonnet using github,then rebuild and the same error occurs. 2>H:\docs\python\pythonnet\packages\UnmanagedExports.1.2.6\tools\RGiesecke.DllExport.targets(42,5): error : Microsoft.Build.Utilities.ToolLocationHelper could not find ildasm.exe.
2>H:\docs\python\pythonnet\packages\UnmanagedExports.1.2.6\tools\RGiesecke.DllExport.targets(42,5): error : C:\Users\scy\AppData\Local\Temp\tmpDBCF\clrmodule.il(62) : error : syntax error at token '.field' in: .field static assembly initonly int64 'D43BE459642EEF2653B9DF1524152974360EA4C5' at I_00002BE0
Addition,the same error occurs when using cmd: python setup.py bdist_wheel.

Second,I unistall VS2015 Enterprise completely,and install VS2015 Professional,the same error ( descriped at First ....field static assembly initonly int64 ...) occurs when rebuilding in VS.
But when trying in cmd " python setup.py bdist_wheel" Rais a Different Error (" .field static assembly initonly int64 ") as follows:
H:\docs\python\pythonnet>g:\pythonEnv\carMgrPy351\Scripts\activate

Updating "UnmanagedExports.1.2.6" to "UnmanagedExports.1.2.7" can not solve the error. I'm confused。May be My windows Lack of some dependency lib?!
Thanks for helping.

perhaps @RobertGiesecke can explain what is wrong?

yajiedesign · 2016-09-02T08:27:32Z

i have same problem

yajiedesign · 2016-09-02T09:31:46Z

ok,I found and fixed the problem.
RGiesecke.DllExport does not support non English ILdasm generated IL file.
You can patch RGiesecke.DllExport with ilspy to fix it.
Find and change "// Code" to you system language.
It is in RGiesecke.DllExport.Parsing.Actions.DeleteExportAttributeParserAction.Execute
@denfromufa
@chunyisong

den-run-ai · 2016-09-02T12:03:33Z

@yajiedesign this is great finding, perhaps you can report this to @RobertGiesecke.

@chunyisong can you test this solution above?

den-run-ai · 2016-09-02T12:09:15Z

@yajiedesign I updated the troubleshooting wiki with your solution:

https://github.com/denfromufa/pythonnet/wiki/Troubleshooting-FAQ

chunyisong · 2016-09-05T01:15:45Z

@yajiedesign @denfromufa I'm sorry,I can not find which code to change! I'm new to .net, Can you tell me which file and line the code is. My ststem is Chinese

den-run-ai · 2016-09-05T03:47:31Z

@chunyisong you need to use ILSPY to open RGiesecke.DllExport.dll installed in pythonnet/packages/UnmanagedExports directory. Edit the code and recompile it with VS.

Alternatively here is a Visual Studio project/solution with Unmanaged Exports decompiled and maintained by @3F:

https://github.com/3F/DllExport

den-run-ai · 2016-09-05T03:48:32Z

here is the line you need to edit:

https://github.com/3F/DllExport/blob/7131da1304504bff6d2117f9fd94d578d9066433/RGiesecke.DllExport/Parsing/Actions/DeleteExportAttributeParserAction.cs#L17

den-run-ai · 2016-09-05T03:50:46Z

Alternatively you can change you system language like suggested here:

chunyisong · 2016-09-06T00:10:26Z

@denfromufa @yajiedesign I changed my win10 system language to english US,and all builds sucess,no error occurs!

In addition,I think there would be a better solution than change language!
Thanks !

den-run-ai · 2016-09-06T00:15:23Z

@chunyisong this solution is due to a problem in third-party library (Unmanaged Exports) not in pythonnet, and opened an issue for this:

3F/DllExport#7

AlexanderHuang · 2018-03-26T07:39:40Z

Hi @denfromufa , the "UnmanagedExports" already has 1.6 version. Is there plan to update the "UnmanagedExports" part to the new version? I am hoping the new version can fix the Chinese Win 10 version problem.

den-run-ai · 2018-03-26T16:02:35Z

@AlexanderHuang have you tested and confirmed that the latest dllexport fixes this issue?
