    @ronaldon said in PDFhummus error: PDFWriter.h: No such file or directory. I need help to use PDFhummus with QT Creator:

    pdfhummus error: PDFWriter.h: No such file or directory

    The same error for the others resources: #include <PDFWriter.h>, #include <PDFPage.h>, #include <PDFWriter.h>, #include <PDFPageInput.h>

    So where are these header files actually located, and what have you done about making your INCLUDEPATH include the directory so that the compiler can find them? I don't see anything in your .pro for this?

    @JonB ,
    I have build PDFHummus source code and add the PDFWriter.lib to my QT project througth: options -> add library -> external libraies.

      That seems to have no answer for what I asked you about where the header files are and how you have told the compile process to find them on include path. Repeating that you have built PDFWriter does not advance you any further.

        I think I understand now, I shouldn't use PDFWriter.lib, instead i should add to my project the PDF Hummus fonts. It is that true?

            Hi,

            As @JonB requested: where is the header of that library located on your hard drive ?

            That path is missing from your INCLUDEPATH variable.

              The header PDFWriter.h is in "D:\WORKSPACE\PDFWriter\PDFWriter" and my project is in "C:\Users\Usuario\Documents\QTProjects\TestPDFhummus"

                  Build the library properly and use it rather than trying to do it by hand like you do.

                          I'm sorry for the missing code tag, i made the correction. I don't know what MinGW will use. I started my first QT project theses days, i just need learn how configure the external library for develop my routine.

                            It's much better with the code tag! :)

                            I'm afarid this is not my area so you'll have to wait for someone else to comment, but: I do not think you are linking against the PDFWriter library.

                            unix:!macx: LIBS += -L$$PWD/./pdf_hummus/Build/PDFWriter/ -lPDFWriter
                            

                            I think you need that line, or similar, for your MinGW. And I assume that line is only applied if you are compiling for unix (and not macx), whereas as you are Windows.

                                  I would start by looking at the actual linker command line being executed during the build. All you show is the errors, without showing the command line.

                                      @ronaldon said in PDFhummus error: PDFWriter.h: No such file or directory. I need help to use PDFhummus with QT Creator:

                                      -L"C:\Users\Ronaldo Fernandes\Documents\QTProjects\TestPDFhummus\pdf_hummus\PDFWriter\debug\PDFWriter.lib" -lPDFWriter
                                      
                                      ld.exe: cannot find -lPDFWriter
                                      

                                      There is something wrong here. You have debug\PDFWriter.lib at the end of the -L argument. That is a file, and that is wrong. It should be a directory where -lPDFWriter is to find the PDFWriter library file.

                                      Compare against what else you have in the llinker line, like

                                      -L"C:\Users\Ronaldo Fernandes\Documents\QTProjects\TestPDFhummus\pdf_hummus\FreeType\debug" -lFreeType
                                      

                                      See how that -L only names the debug directory for the -lFreeType to search for it? That's how it should be.

                                      Additional to that you have PDFWriter.lib mentioned. But (so far as I know) .lib files are only used as library files for the MSVC compiler. You are using MinGW, its libraries should only be .a files, I believe.

                                      Go look at how the path ending in debug\PDFWriter.lib is being generated, and correct. And make sure what you have for PDFWriter is for MinGW, not for MSVC.

                                        @JonB, Is there a possibility of having a version of the Hummus PDF for MinGW, or do I have to somehow change the output of the compilation to the ".a" file? The PDF project Hummus was developed in the visual studio as far as I could see. What I need is to compile it and add it to my QT Creator project.

                                          You cannot link mixing compilers.

                                          MinGW produces .a libraries. MSVC produces .lib libraries. You need to pick one of the two compilers and compile both your own code and third-party code with the same compiler toolchain.
