I see it, thank's but have only signature, not code.
By the way 'out/debug/pdfium_test --png /home/a/mozilla.pdf' runs ok and produce images.
So i must find the pdfium_test code to see how it works.

But i am emotionally connect with wxWidgets framework for all this job have done, so i'd like to use wxPDFView in my project.
BTW *buildtools is the folder that gn.py uses for making args.gn file (gn args out/debug) in out/debug dir.
If we clone from github there is not this folder. So we must use instructions as above exactly and download from google-git. I write those things to remember and for anyone that will help.
Thank's again.
Jim

Hmm, maybe there: https://pdfium.googlesource.com/pdfium/ ... um_test.cc or https://github.com/hfiguiere/pdfium/blo ... um_test.cc or https://gist.github.com/bnagy/ef5a14ff8f22532c857c

Oh, thank's, i have study ... ok, very well :) .
Before of that i will try to make the wxPDFView lib, for study.
I'd like to learn new things, it is very pleasant.
Now i have all libs in obj dir, and all in out/debug dir of PDFium.
What command must give to terminato to make the lib?
Just cmake?
As i see libs that want FindPDFium.cmake are
fpdfapi, fpdfdoc,fpdftext,fxcodec,fxcrt,fxedit,fxge
fx_agg,fx_freetype,fx_lcms2,libjpeg,fx_libopenjpeg,fx_lpng,fx_zlib,icui18n,icuuc,javascript, pdfium,pdfwindow, v8_libbase, v8_libplatform, v8_snapshot.
PDFium libs are
drm.a, formfiller.a, fpdfapi.a,fpdfdoc.a,fpdftext.a,fxcodec.a,fxcrt.a,fxge.a,fxjs.a, image_diff.a, pdfium.a,pwl.a,test_support.a
How i made lib?

I don't know Ninja, so I can't help, but reading this https://github.com/pvginkel/PdfiumViewe ... ing-PDFium and this https://stackoverflow.com/questions/296 ... pplication I think it should be built at the step you are... And after this, you have to link it with your own project (eg. as did this guy there: https://stackoverflow.com/questions/296 ... pplication).

If your project is using CMake, this could be of some help: https://groups.google.com/forum/#!topic ... C-VO8ieaaU

But, frankly for the PDFium specificities, you should be better to join https://groups.google.com/forum/#!forum/pdfium and be back here for the wxWidgets related topics...

I played around with wxPDFView under Windows about a year ago. I just looked into the sample project and it links all the different pdfium libraries individually.

In sample can i insert all .h and .cpp files from wxPDFView like i did with wxPDFDocument?
To do not make lib but only insert sources?
Add if yes, must some source not be insert to project?
For example dirs bellow must inser .h and .cpp files?
wxPDFView/art/
wxPDFView/include/private/
Thank's
Jim.

Ok red letters are for developers. So with options>'Suppress dev warnings' red letters disappear.
Truin to Configure, ok, and the Generate, ok.
Then in terminal with make i have problems.
First of all "/home/a/wxPDFView/include/private/PDFViewBookmarks.h" the #include "fpdfdoc/fpdf_doc.h" does not exist in home/a/repo/PDFium/..., only #include "fpdf_doc.h" at "include/private/PDFViewBookmarks.h".

Making comment the line...

Code: Select all

#ifndef PDFVIEW_BOOKMARKS_H
#define PDFVIEW_BOOKMARKS_H

#include "PDFView.h"
#include "fpdf_doc.h"
//#include "fpdfdoc/fpdf_doc.h"

class wxPDFViewBookmarks
{
public:
	wxPDFViewBookmarks(FPDF_DOCUMENT doc);

	const wxPDFViewBookmark* GetRoot() const { return m_root.get(); };

private:
	CPDF_BookmarkTree m_tree;
	wxSharedPtr<wxPDFViewBookmark> m_root;
};
That's ok, but with make compiler says ...
a@a-desktop ~/wxPDFView/libs $ make
[ 7%] Building CXX object CMakeFiles/wxPDFView.dir/src/PDFView.cpp.o
In file included from /home/a/wxPDFView/include/private/PDFViewImpl.h:27:0,
from /home/a/wxPDFView/src/PDFView.cpp:11:
/home/a/wxPDFView/include/private/PDFViewBookmarks.h:25:2: error: ‘CPDF_BookmarkTree’ does not name a type

^
make[2]: *** [CMakeFiles/wxPDFView.dir/src/PDFView.cpp.o] Error 1
make[1]: *** [CMakeFiles/wxPDFView.dir/all] Error 2
make: *** [all] Error 2
Any advice?

There are chances that CPDF_BookmarkTree belongs to PDFium. So, your project have to be able to reach the PDFium headers.

On https://github.com/TcT2k/wxPDFView, I read:
Use the included CMake file in your project and link wxPDFView lib (will link the required pdfium libs)
Or contact the author for detail (it's always the same: better to ask to the right person, dkaip).

Thanks eragon, but cmake-gui already has wxPDFView.cmake file and generation is ok.
Now i must see how to construct lib. As i see none use linux for construct libs.
I wiil try myself.
