    @Lordful Seems like you are not linking some base framework and libraries like libpng and CoreFoundation.

    @jsulm nop, it's not amd64 it's arm64 ;)

      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

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

            @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.

              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.

                @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.

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

                    @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.

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

                        How did you install Qt ?

                          @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 :

                          1. CMake
                          2. XCode building

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

                              @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
