Anyone building pdfium for ios/ios simulator?

[Adam Schepis]

Having issues getting this all squared away so that i can link it into my iOS app. Anyone having luck with this?  Basically it comes down to adding more architectures, i think.

[Adam Schepis]

I've done the work to get pdfium working in iOS.  It involves removing v8 when os==ios (so you can't load pdfs with scripts) and doing a couple other minor things to properly detect iOS in the code.  I'm wondering what the best way to contribute this back is.  Is using `git-cl` etc as state here (http://dev.chromium.org/developers/contributing-code) going to work or do i have to point it at a different code review server?

Adam,

Did this ever get integrated? If not, I'd love to know how to get the working since I also need to target iOS.

Thanks,

joe

More specifically I have already had to do the work to strip v8 out of the library but figuring out how to get it to configure and guid for iOS would be great.

Joe, 

I did get it building and working in my iOS app. you can see my fork here:

https://github.com/aschepis/pdfium

I never heard back about how best to contribute back but I need to find the time to just put a patch together and send it along

Awesome, thanks! You saved me a lot of time and frustration figuring out how to get GYP to work for this.

 

How do you build for iOS with this? Does the generated xcodeproj now have an iOS target in it or do you have to add a command line parameter to GYP to get it to generate an iOS specific xcodeproj?

Right, I’m not sure if thats 100% correct, but its in a “works for me” state and since those top level projects don’t produce any artifacts it seemed alright to me.

Lifesaver... thank you! I've had a hell of a time getting help in the mailing list and the GYP documentation is rather vague on this part of the gyp magic.

Happy to help!

Yep. Thanks. You truly did save me a lot of grief as I didn't even realize it would be that easy.i was trying to set up configurations and targets and grasp.

No, i haven’t run into that. What version of Xcode? What device? What other libraries/frameworks are you linking?

Have you run into any problems linking PDFIUM when building iphonesimulator?

 

Specifically: 

Undefined symbols for architecture x86_64:

  "_opendir$INODE64", referenced from:

I did this via my hawkish shell script.  excerpt below (tried to remove unimportant stuff while still keeping it working. When building for IOS just set the PLATFORM var:

PLATFORM=apple-ios ./script.sh

I didn’t include it in the gyp files since it was just as easy to set the variables via xcodebuild params.

#!/usr/bin/env bash

: ${PLATFORM:="apple-darwin"}

ROOT_DIR=$(git rev-parse --show-toplevel)

case $PLATFORM in

"apple-darwin")

    DEVELOPER=$(xcode-select -print-path)

    LIPO=$(xcrun -sdk iphoneos -find lipo)

Looking at your changes I don't see anything that would produce output for the simulator. Do you compile in Xcode at all and try ti run in the simulator?

Hi,

I finished my script to build the PDFium to iOS. All is here with manual patchs:

https://github.com/prsolucoes/mobile-pdfium

But i have some issues after compile. All issues is described here:

https://github.com/prsolucoes/mobile-pdfium/issues/1

Can you help me?

[Dimuthu Upeksha]

Thanks, Paulo for coming up with build scripts. Is this work being used in any serious project and is it up to date with the recent Pdfium version?
