Bitcode support

[Studiosus]

Hey! Many thanks for the project, it's great!
Wanted to ask is it possible to add bitcode support?

[vfr]

Bitcode support is possible - one just needs to build PDFium with the right compiler flags and set the framework bitcode build option. I'll put together instructions for building PDFium from source for iOS shortly so you can do this.

Thank you, +1 for tut on PDFium compiling, or please compile a bitcode enabled build.

Hi,

I made a repository with instructions to build it. It is working very well. But i need solve some problems related here:

paulocoutinhox/pdfium-lib#1

Thanks in any help.

Sorry to bug you, @vfr, but you seem to be the only person on the internet that knows how to compile PDFium for iOS correctly. It would be incredibly helpful if you could write out how exactly you managed to compile the binary.

Hi,

It is working. If anyone wanna, it is building on travis and all instructions is here:

Hi,

I make a project to build pdfium master branch for iOS.

It is working fine for arm, arm64 and macos.

There is only one problem on ios simulator (os=ios and cpu=x64).

I post the issue on project here:
paulocoutinhox/pdfium-lib#5

Can anyone help me solve this pls.

Thanks.

@PRSolucoes I tried the prebuilt binary with bitcode enabled, got this error:

Undefined symbols for architecture arm64:
  "_FPDFDest_GetPageIndex", referenced from:
      -[UXReaderDocument actionForDest:] in UXReaderDocument.o
      -[UXReaderDocumentPage actionForLink:] in UXReaderDocumentPage.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Any idea what's wrong?

use FPDFDest_GetDestPageIndex instead of FPDFDest_GetPageIndex

@paulocoutinhox Can you enable Bitcode support for this repo? I just had a try but to no avail.
