Qt Creator + adding external libraries = " ld: symbol(s) not found for architecture x86_64 "

joinee

Hi all,

I just start working with Qt, and have problem. I were trying to find some post with similar issues but didint find any solution.

All is going about reading data and printing pdf from it. I decided to use:

Qt to make some friendly enviroment,
libxl - library to read .xls files (http://www.libxl.com) ,
pdflib - library to print .pdf files (http://www.pdflib.com) ,

After dowloading libxl library, i found an examples inside of package. One of them was addapted to Qt. I used it and it works good.

#include "mainwindow.h"

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();

return a.exec&#40;&#41;;

}@

and some mainwindow.ui which probably isnt important.

Next i try to add second library - pdflib. In this package were examples for c, cpp, c obj. Only in c example was folder /lib where was libpdf.a . I imported library to Qt project by right mouse clicking in .pro file and choosing add library -> appropriate options. Then to .pro file was added:
@
macx: LIBS += -L$$PWD/../../../bind/c/lib/ -lpdf

INCLUDEPATH += $$PWD/../../../bind/c/include
DEPENDPATH += $$PWD/../../../bind/c/include

macx: PRE_TARGETDEPS += $$PWD/../../../bind/c/lib/libpdf.a@

Afterwards I added to mainwindow.cpp little bit of code to try if it works:
@
...
#include "pdflib.h"
...
void MainWindow::generateExcel()
{
...
PDF * p;
/* create a new PDFlib object */
if ((p = PDF_new()) == (PDF *) 0) {
// comment
}
...
}
...@

Finally i tried to compile project but error occurred:
"symbol(s) not found for architecture x86_64"

All output in next post.

Checked file libpdf.a in terminal and it returned:
@libpdf.a: Mach-O universal binary with 2 architectures
libpdf.a (for architecture i386): current ar archive random library
libpdf.a (for architecture x86_64): current ar archive random library
@

I tried to change include in mainwindow.cpp to:
@extern "C" {
#include "pdflib.h"
}@
But didnt help.

Adding to .pro file:
@
CONFIG += x86_64
@
changed nothing to.

I tried include .h files from both (c, cpp) versions of library (pdflib) without importing it by Qt, but result was the same.
I attempted also using other libraries for making .pdf files (e.g. libharu) without success.
By reading other threads I learned that it is a linking program.

More info:
Mac OSX 10.7.4
Qt 5.0.2
Qt Creator 2.7.0
libxl 3.4.1.4
pdflib 8.0.5

If anything more will be needed just say.

Spend last 6 h while trying to find solution and fix this issue.

Thanks for any hints!
