Build scripts for the PDFium library.

PdfiumBuild

This project contains a build script to build PDFium for Windows. The process to build PDFium used here is described at https://github.com/pvginkel/PdfiumViewer/wiki/Building-PDFium. Basically it does a standard build, except that a .dll is build.

The main purpose of this project is to automate building the pdfium.dll support library and NuGet packages for the PdfiumViewer project. However, unmodified versions of the PDFium library are also provided.

Archived

I regret to announce I'm archiving this project. I haven't been able to spend any real time on this for a long time now, and must face the fact I'm not in a position to properly support this project.

I'm archiving this project together with the PdfiumViewer project for which this build project was created. Have look there for a bit more background and information.

I'm also shutting down the build server. The Builds folder in this project contains some archived built DLL's that may be of use. See the README there for more information on them.

I've had a great time developing this project and helping you out using this project, and I'm sad I have to now close this down. I hope PdfiumViewer and PdfiumBuild have been of value to you. The source code and NuGet packages won't be going anywhere, so keep using them if they're of value to you.

NuGet packages

Besides, the pdfium.dll files, NuGet packages are automatically build and published by the build server.

The following NuGet packages are available:

NuGet package	Architecture	V8 support	XFA support
PdfiumViewer.Native.x86_64.v8-xfa	64-bit	Yes	Yes
PdfiumViewer.Native.x86_64.no_v8-no_xfa	64-bit	No	No
PdfiumViewer.Native.x86.v8-xfa	32-bit	Yes	Yes
PdfiumViewer.Native.x86.no_v8-no_xfa	32-bit	No	No

These NuGet packages contain the PDFium DLL and a MSBuild properties file to copy this to the correct folder in your output directory.

Depending on your needs, you can choose the NuGet package(s) you need. The ones with V8 and XFA support are bigger, but support more features. Also, the V8 version does not support Windows XP so if you need support for Windows XP, you need to choose one of the libraries that does not contain V8 support and include an updated version of the dbghelp libraries. These can be found in the Support\dbghelp directory.

The version numbers of these packages are determined automatically and are composed of the current date and the build number from the Jenkins build server.

The build server

A build server has been setup to compile PDFium weekly. The results can be downloaded from https://assendelft.webathome.org/Pdfium/. Please note that this is a personal server, which may be down at any time.

The URL points to a website that gives a view over the build output. It shows what builds succeeded and what builds failed and provides access to the build results.

Builds can fail for a number of reasons. For example, at some point the builds failed because issue v8:6068. This specific issue has been solved by now, but new issues can arise.

Feel free to create an issue if the builds are failing.

Adding build scripts

If you'd like to have a specific configuration of PDFium build, please provide a pull request. In the project, the Scripts directory contains scripts to configure a PDFium build. In such a directory, there is a args.gn file and optionally a contrib directory. The args.gn file configures the GN build tool and the contrib directory contains source files to be included in the compilation. If you want to have a configuration added, please submit a pull request with a new sub directory under the Scripts directory.

Building PDFium yourself

Alternatively you can use the application to build PDFium yourself. Building PDFium can take quite a while. To speed this up, you should remove all configurations under the Scripts directory that you don't need to be build before running the build script.

pdfiumbuild's Issues

Could not add to solution

First of all, thanks for the work you did creating this dll and the porting to C# of Pdfium.

I'm trying to add native dll to my project via NuGet but I get this error:

Could not install package 'PdfiumViewer.Native.x86_64.v8-xfa 2018.2.11.249'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.7', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.

I also tried to target to:

• .NETFramework 4.6.1
• .NETFramework 4.6
• .NETFramework 4.5
• .NETFramework 4.0

but still the same issue.

I'm on Ubuntu 17.10 and I'm working with MonoDevelop
How I can fix this?

successfully built dlls from https://assendelft.webathome.org/Pdfium/ did not work, they are broken

Dear Van Ginkel,

first of all, thank you very much for your great PDF Projects.

i have tried to use the pdfium.dll from your builtserver https://assendelft.webathome.org/Pdfium/ for a project of mine.
The problem is, that the build seems to be built successfull, but when i try to put it into my project references it says that the .dll is corrupt.

For example: all builts from the 2018-01-07 are corrupt.

is it maybe possible that you upload a current working version of the pdfium.dll?

Thanks you very much,

Andreas Greiff

The build server is not generating the pdfium.dll

The build server https://assendelft.webathome.org/Pdfium/ is not generating pdfium.dll from mid of May 2017. Could you please resolve the issue?

Build server builds are failing

Just looked and the last build that succeeded was on 2018-04-08
https://assendelft.webathome.org/Pdfium/

Could not copy "\packages\PdfiumViewer.Native.x86_64.v8-xfa.2017.12.4.236\build\x64\pdfium.dll" to "bin\x64\pdfium.dll". Exceeded retry count of 10. Failed.

I have found the issue in MsBuild scripts. When package added to the WebSite project then IIS locking file bin\x64\pdfium.dll.

Build script tries each build copy pdfium.dll.

To resolve this issue you need to change:
<CopyToOutputDirectory>Always</CopyToOutputDirectory>
to
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>

in PdfiumViewer.Native.*.props files

Bug found - Env.cs

WebClient.DownloadFile is called before CreateDirectory is called and an exception is raised - CreateDirectory must be called first

Can you explain how to provide arguments.

I tried you steps provided in the below link but i try to run this project arguments are null. Can you please explain to provide the arguments to this project?https://github.com/pvginkel/PdfiumViewer/wiki/Building-PDFium

build server: x86 builds are failing

The x86 builds are failing since 2017-12-17.

(This is a great project, thank you for that.)
