How to build CefSharp ?

[pattie103]

Hello, 

I've been following the building guide of CEFSharp ( https://github.com/chillitom/CefSharp/wiki/Building-CefSharp ) and i'm stuck on where i should place the libcef.lib, libcef_dll_wrapper.lib and libcef.dll  in the CEFSharp project to be able to build.

Currently i have CEFSharp v1.19 and CEF branch 1180, both of them go with Chromium version 21.0.1180.18.

Can anyone give me some instructions on how to go on from the last point in the guide ?

Thanks.

The instructions on the chillitom fork wiki are out of date, here are my more recent instructions:

https://github.com/ataranto/CefSharp/wiki/Building-CefSharp

The .lib and .dll files are checked into the CefSharp repo, just replace them with the updated files genereted by your CEF build, or use the included script.

Also, note that my 1.19 release branch is based on CEF branch 1084, _not_ 1180. This may be the cause of your problems.

Thank for the information.

Yes, I just haven't made a binary release from that branch yet.

Will touch scrolling work in CEFSharp if i set EnableTouch true in the CEF build ? i'm trying to get touch events in the browser, but i'm not sure if it will work if i do it this way.

Thanks.

I've build the CEF files needed to build CEFSharp and used update_from_cef.sh to get the correct files from CEF.

But when i start building i succeed in building the cefsharp project, cefsharp.wpf project, cefsharp.wpf.example project after setting .net to 4 and cefsharp.example after setting .net to 4.

but when i try to start cefsharp,wpf.example in debug mode i get this error:

I read a little on the internet and found that this may be and win32 / x64 problem.

Also the libcef.dll file i build in the CEF project is 127.467 KB, its and lot bigger than any other libcef file i have seen in the CEFSharp projects.

Can you help me with this ?

I haven't spent any time trying to build for .NET 4. A few public forks on github have converted to .NET 4.0, you may be interested in looking at their changes.

Also the libcef.dll file i build in the CEF project is 127.467 KB, its and lot bigger than any other libcef file i have seen in the CEFSharp projects.

Not sure what you mean by this, libcef.dll is > 20MB .

What you've found is problably the cause of the problem. This usually happens when a 64-bit process tries to load/execute 32-bit code. I guess your main executable (examples.wpf.exe) is compiled for AnyCPU and you run it on 64-bit machine. This makes it a 64-bit process and thus cannot load 32-bit cef. Try setting the debug build of the main exe project to compile only for x86. This should force everything to run in 32-bit mode. 

About the size - you probably meant 127.467 MB not KB. From my experience, the debug build of libcef is about that size (the pdb file is even bigger). However as Anthony mentions the release version is much smaller and you could you it in both debug and release builds of CefSharp.

Hope this helps.

I tried your sugestion, and it works.

Thank you very much.
