cefsharp 37 build getting failed with VS2010, what to do?

[rover886]

I have downloaded cefSharp-master.zip and oped in VS2010 downloaded packages from nuget. When I build solution I get errors as follows:

error LNK1104: cannot open file 'libcef_dll_wrapper.lib
error LNK1181: cannot open input file 'libcef_dll_wrapper.lib

What can I do?

You can do this: With VS2010 for building CefSharp from source you need to provide a cef.sdk NuGet built for that version yourself. See under requirements in https://github.com/cefsharp/CefSharp/wiki/Building-CefSharp

The reason is core CefSharp developers currently only have VS2012 and VS2013.

NuGet Restore is completed at my side. packages/ folder contains cef.redist.x64.3.2171.1979, cef.redist.x86.3.2171.1979, cef.sdk.3.2171.1979. still on Build Solution I am getting the error.

If you look inside the packages\cef.sdk.3.2171.1979\ folder from the official NuGet you will see lib's for VS2012 and 2013, but nothing for 2010. That's why you need to prepare a cef.sdk for yourself for VS2010.

It's a matter of:

1. Downloading the right CEF version from http://cefbuilds.com
2. Use the awesome build.ps1 in our cef-binary repo to repackage to a VS2010 cef.sdk. Before running it adjust comments at https://github.com/cefsharp/cef-binary/blob/master/build.ps1#L373 to enable 2010 and disable the other compiler versions
3. Setup a local NuGet package source with your new package according to nuget's doc or manually extract/unzip the NuGet into your CefSharp packages folder in place of the official

I am so sorry because asking you so basic things. But I have done first two steps. I downloaded cefbinary from https://github.com/cefsharp/cef-binary changed build.ps1 as you told in step 2. but I am not getting anything about step 3. I mean how can i download and build files for vs2010. I am so sorry.

No problem! Both writing and understanding stuff like this just via short text descriptions is hard. But I'm sure we'll succeed in the end 😄 Now it's me who is confused about what you write ...

So I'm not sure how far you got? Did you run build.ps1 and now have your own .nupkg files, including cef.sdk - but now don't know how to use it to build CefSharp - or did building cef.sdk fail?

If build worked and you're stuck with step 3. then googling for "NuGet local package" should give https://docs.nuget.org/Create/Hosting-Your-Own-NuGet-Feeds#creating-local-feeds as one of the first hits.

Thanks for your such a nice motivation 😄 :P. well as you said I run build.ps using power shell but I am continuously getting following error:

PS C:\Users\amoghs> E:\Downloads\cef-binary-master_V37\cef-binary-master\build.ps1
Exception calling "DownloadFile" with "2" argument(s): "The remote name could not be resolved: 'www.nuget.org'"

•     $Client.DownloadFile <<<< ('http://nuget.org/nuget.exe', $Nuget);

I have checked with connectivity, firewall as well as proxy server. it's all seems fine.

[jornh]

You're welcome. You know ... we try ... 😄

Hmm, some time since I actually have used that script. And because I already have that file I won't experience any download problem/hit that line in the code. Does downloading http://nuget.org/nuget.exe and manually placing it into your %LOCALAPPDATA%\nuget\ folder bring you past that step?

[amaitland]

@rover886 Are you building a custom version of CefSharp with some modifications? Far as I'm aware the stock standard nuget packages will work just fine under VS2010 long as you have VC++ 2012 Redist installed. (I could be totally mistaken, as it has been a very long time since I tried VS2010)

[rover886]

@amaitland no I am not building custom version of CefSharp. I have just downloaded CefSharp-master and wanted to run and then use in my application by adding some code, like custom schemes and etc. VC++2013, VC++2010 is installed in my machine. still do i need to install 2012 version?

[amaitland]

You can use the CI Builds if you need the latest master

https://github.com/cefsharp/CefSharp#nuget-packages

Official versions require VC++ 2012, which is independent of VS 2012 and can be used with VS2010, VS2012 and VS2013.

VC++ 2012 being Visual C++ 2012.

You can use VS2013 to build a master version of your own, you just need to make sure you compile in Release mode and that VC++ 2013 is installed on your target machines.

@amaitland i installed VC++2012 and tried to build but it's still giving me build error

error LNK1104: cannot open file 'libcef_dll_wrapper.lib
error LNK1181: cannot open input file 'libcef_dll_wrapper.lib

[jankurianski]

This is a C++ build error. So it seems you are still trying to build CefSharp. Why not use NuGet?

[rover886]

@jankurianski By nuget I get message as Finished configuring this solution to restore NuGet packages on build. and when I build solution i build error.
