Qt 5.5 - XCode building failed - Linking failed - Poppler

jsulm

@SGaist Yes , you're right. It looks so similar :-)

Lordful

Hum I will try to add these two libs in the library field and see what I get.

@SGaist It seems that QtCore & libpng are already inside of "Header Search Paths" inside of Poppler & Poppler-qt5

SGaist

The symbols that are missing comes from OS X/ iOS frameworks (e.g. CFArrayCreate) not Qt

Lordful

@SGaist Hum I will check that, should I add the path to Core in library ? (Anyway, I will try)

Lordful

@SGaist Isn't a problem of architecture ? It seems that XCode try to use some librarie which has been build for OS X and not for iOS.

SGaist

Did you apply the patch proposed in the bug report ? And re-configure / re-build the project ?

Not seeing the linker output I don't know if it get the framework for the wrong architecture or if they are just missing from the linker options.

Lordful

@SGaist Hum as I said earlier, it's no more a problem with gl.h but a problem on linking the two libraries.

Actually, the compilation of Poppler succeed but the compilation of Poppler-Qt5 fail when XCode try to link the two libs.

And before, I solved the problem of "gl.h" by downloading Qt 5.6 & check my path env to point to ios/bin.

SGaist

What about building it using Qt Creator just to ensure you use the right kit ?

Lordful

@SGaist Yes I tried.

But I can only run/compile for Desktop. When I try to add a Kit, if I choose to add a kit for iOS, there is no generator in CMake Wizard.

So ... it's strange.

Lordful

@SGaist I had update this topic and here is the actual error output from XCode when I try to build poppler-qt5 :

And there is more "referebced from" error. And this error appears when linking.

SGaist

How did you install Qt ?

Lordful

@SGaist Simply by installing with Qt Unified Mac (dmg).

Its seems to be a problem of lib, maybe ?

I'm trying to compile Poppler for iOS in 2 steps :

CMake
XCode building

But when you look at the error in XCode, it seems that lib aren't found. So weird.

@Lordful Hello , Did you managed to build Poppler for IOS ? I have been trying to do it for 2 days :(

Muhammet Ali Asan

@SGaist Lordful seems to have succeeded building Poppler with qt5 on ios . I could not hold the list of error I encountered.
I am trying to build fontconfig , openjpeg and freetype for ios because they are asked in cmake. If I get to Xcode project it fails with different errors. I am new to Ios, and mac os . Should I build the dependencies from source for ios ? If so some of them are harder than poppler
