Compiling wkhtmltopdf

[Mark Thomson]

I'd like to try to compile wkhtmltopdf locally so I can take a closer look at some of the seg fault errors I've been getting. However when I try to follow the instructions here - http://code.google.com/p/wkhtmltopdf/wiki/compilation I get a lot of errors like this one -

../lib/pdfconverter_p.hh:97:50: error: class ‘wkhtmltopdf::PageObject’ does not have any field named ‘headerReserveHeight’

Looking at the source, it appears that the problem is that the preprocessor symbol __EXTENSIVE_WKHTMLTOPDF_QT_HACK__ is not defined. 

When/how/where is this supposed to be defined?

Ok so I added __EXTENSIVE_WKHTMLTOPDF_QT_HACK__ to the defines in src/lib/Makefile, and that got me past the immediate hurdle, but now I've run into the stuff below.

Any advice? 

BTW, I'm on a linux mint box, and I went through the process of installing QT by hand as described in the instructions before trying to compile wkhtmltopdf.

Hmm... there is a QWebPrinter class defined as part of wkhtmltopdf-qt (src/3rdparty/webkit/WebKit/qt/Api/qwebframe.h). Are those files meant to be included in the compilation process? Would appreciate some help.

Hello. Yes you are suppose to use my version of qt, if you want all
the features.

For now use this branch
https://qt.gitorious.org/~antialize/qt/antializes-qt/commits/4.8.2, as
it works with wkhtmlopdf master, and is a never qt version. I am still
in the process of getting this new qt version working propperly,
currently there are still some issues with wkhtmltopdf running very
slowly with this new qt.

After checking out the qt branch, remember to run the bin/syncqt, then
run configure, you can exclude some stuff so the compilation will be
faster, but the default values are generally ok. Remember to set the
-prefix though

Thanks Jakob! It's all working fine now (The only very small issue was that I needed sudo on make install). The seg faults that I had previously been seeing with wkhtmltoimage seem to have been resolved as well.

Mark.

[Jakob Truelsen]

Yes in general, a non static build, like the one you just did, seems
work much better then a static build, however it is very platform
specific, and hard to distribute.

Hi Jakob,

Is there any way in which we can build a static binary now? I have posted to the group about the errors I am receiving: https://groups.google.com/forum/#!topic/wkhtmltopdf-dev/eDRiYdy2fRs. Regular compilation works. Just the static binary build fails.

I am sure a lot of people would appreciate being able to get a static build which can be transferred to other machines without having to recompile every time. Or else, once compiled on a machine, if you can just tell us which files are to be transferred to another machine for it to work, that would be a huge help as well.

Thanks.

Anjan
