[poppler] Error: Couldn't find a font for 'Helvetica'

[LOPEZ OLIVIER]

Thank you for your answer, after reading so much thing about my problem.
I identifiate the problem that came from fonts.conf.
It's not present on windows or I just don't know where I have to put in because it's not my own libpoppler-qt4.dll.
It's certainly works in linux for my application. The big problem it's to compilate the library for windows.
In any case thank you for your helping.

Poppler has worked with Helvetica for a very long time.  On Windows, it should be mapped to the arial fonts.  I don't know why it's failing in your case, but you could compile the source yourself and step through the code to find why it's not working.  I would start with SplashOutputDev::doUpdateFont in the file poppler/SplashOutputDev.cc since I think that's where that error message comes from.

And no, we don't distribute binaries ourselves, only the source.  I don't have much experience compiling things on Windows so I probably won't be able to help with any compilation errors.  I understand cmake is involved and lots of fiddling with dependencies, but not much else.
