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?

[jornh]

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.

[rover886]

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.

[jornh]

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

[rover886]

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.

[jornh]

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.

[rover886]

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

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.

[rover886]

@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.

[jankurianski]

So you are getting this error when building your C# solution? Could you post the full output of the build action? Debug menu > Windows > Output, then choose Show output from: Build.

[rover886]

Yes I am getting error while building C# solution. Here is build output :

I'd still strongly recommend using the Nuget package. If your having this much trouble building from source then it's likely to be the simplest solution.

@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.

Providing the build error for that problem is likely to be far more productive. I'd highly recommend reading https://github.com/cefsharp/CefSharp/wiki/Trouble-Shooting, specially the parts about AnyCpu are a good place to start.

[rover886]

Yes I also like that nuget will do all the stuff, but don't know why its' not working or where I am doing wrong.

I already read trouble shooting article and I have taken care that all projects are set to x86/win32. Hey I remember one thing, while opening solution file for the first time I changed targeting framework version to 4.0, is this the reason of getting fail or as @jornh said at #810 (comment) I need to build libcef_dll_wrapper.lib file for 2010 as from nuget only files for 2012 n 2013 are coming?

[amaitland]

What is the exact error your seeing?

[rover886]

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

I have updated my last comment.

[amaitland]

If your trying to build master or another branch under VS2010 then you'll need to compile cef-binary from source supporting VS2010, I don't recommend this unless there's no other choice.

If your just wishing to use CefSharp in either a WinForms or WPF application then you just need to use

https://www.nuget.org/packages/CefSharp.WinForms/
https://www.nuget.org/packages/CefSharp.Wpf

Examples of consuing the release Nuget packages can be found here at https://github.com/cefsharp/CefSharp.MinimalExample

For reference master is not version 37, it's version 39, which is in the -pre release phase and should be out shortly (it's a little behind schedule at this point in time).

[rover886]

Yes!!! 😄 Finally I am successful to build master in VS2010 hushhhhh!! don't know you may be feel I am over excited but so many things I have learned nuget,cefsharp's master branch, CefSharp for winform, cefsharp-cefbinary, building libcef_dll_wrapper.lib for VS 2010 using cefbinary etc

@jornh, @amaitland, @jankurianski you guys helped me a lot by giving proper direction time to time with immediate reply. Thnaks 😄 🎁. @jornh if you permit I will like to close this issue by writing small guide which will help other user to build master in VS2010 along with building and generating 'libcef_dll_wrapper.lib' file.

😄 😄 😄

[jornh]

Great! I think we can all relate to that feeling of needing to celebrate 👍

@amaitland and @jankurianski I guess there still might be value in being able to build from source for people wanting to step into our libs to help figure out how things work. (And it's our secret weapon to convert users into forkers and suddenly committers). But I realize the need to support VS2010 may be a lot less now with the VS2013 community edition available. Apparently @rover886 was the first to try this for a while - at least as a new user needing help.

Another possibility I'm pondering is if it would make sense to add a JustBuildTheExamplesMaam.sln they are important "documentation" and it should remove the need for cef.sdk matching the local VS version. Soon we will probably see someone not being able to build with VS2015 😄

Yes @rover886 by all means do share your experiences. It gets harder over time for us in the project to see things from the angle of a newcomer to the project. Personally I'm a bit curious about the NuGet.exe download issue in #810 (comment)? I think this is a point where build.ps1 maybe is a bit over engineered.

[jornh]

Oh well, guess I spoke too soon forgot entirely that the examples are now .NET 4.5 and this not appropriate for VS2010. Guess we should just encourage people to use VS2012+ and discourage VS2010 source builds. Dooh!

[rover886]

@jornh I am frustrated with download issue with nuget I don't konw it's just me who is facing this issue or what, I posted one question on other forum, also I contacted to you via nuget.

I am just thinking to post new question that is coming in my mind is about .NET version, is it really necessary to use .NET4.5 😄 hope so you will answer it 😄

[jornh]

Yes and I posted a comment to your question on http://stackoverflow.com/questions/28541343/cefsharp-winforms-nuget-download-issue so go there and look. Also pinging us on NuGet.org in addition won't do any good other than flooding our inboxes basically. Please understand CefSharp is just a spare time "hobby" for us.

.NET 4.5 only recently was added as a requirement to only the CefSharp.*.Example projects as witnessed by GitHub history fc65192. And only after a lengthy open debate in #381. All of the binary NuGets CefSharp.<something> we plan to keep on 4.0 for the foreseeable future. If you look in any other .csproj file including those in the CefSharp.MinimalExample repo you will see that.

[amaitland]

@jornh I am frustrated with download issue with nuget I don't konw it's just me who is facing this issue or what, I posted one question on other forum, also I contacted to you via nuget.

Make sure you have the latest Nuget package installed into VS2010. Otherwise you can download Nuget and use the commend line to restore. I don't beleive this issue has anything to do with CefSharp.

NuGet 2.8.3 Released
NuGet 2.8.3 was released on November 5th. For Visual Studio 2010, Visual Studio 2012 and Visual Studio 2013, upgrade now using the Visual Studio Extension Manager.

Make sure you have 2.8.3 installed

I am just thinking to post new question that is coming in my mind is about .NET version, is it really necessary to use .NET4.5 😄 hope so you will answer it 😄

As .Net 4.5 is supported on every current version of Windows, I don't see this being a problem personally. Specially as it's only the example projects that have that dependency.

[amaitland]

Closing due to lack of feedback.

Please note that I've also changed the Nuget Restore method as per http://blog.davidebbo.com/2014/01/the-right-way-to-restore-nuget-packages.html

It should be more reliable for our managed packages.

[tafia]

Trying to reopen the issue ...
We'd like to use CefSharp.WPF for an internal tool in our company (200+ users). Unfortunately VC++ 2012 is not installed per default (only VC++ 2010) on user systems.
As asking for all users to contact the support team to have VC++ 2012 is not a solution, is there a way we can build against VC++ 2010 only?

[rover886]

@tafia you can manually keep VC++ 2012 files in your application folder (files must be parallel to cefSharp DLLs).

Following files are needed:

msvcp120.dll
msvcr120.dll
vccorlib120.dll

I achieved this by adding all above files as module in setup and deployment project, so there is no need to install VC++ 2012 per machine. I hope this will solve your problem.

[amaitland]

@rover886 Excellent suggestion 👍

[tafia]

@rover886 thanks!
Let me try
