  • 0

I just got help in how to compile this script a few mintues ago on SO but I have managed to get errors. I am only a beginner in C++ and have no idea what the below erros means or how to fix it.

This is the script in question. I have read the comments from some users suggesting they changed the #include parts but it seems to be exactly what the script has, see this comment.

[root@localhost wkthumb]# qmake-qt4 && make
g++ -c -pipe -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fstack-protector --param=ssp-buffer-size=4 -m32 -march=i386 -mtune=generic -fasynchronous-unwind-tables -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -I/usr/lib/qt4/mkspecs/linux-g++ -I. -I/usr/include/QtCore -I/usr/include/QtGui -I/usr/include -I. -I. -I. -o main.o main.cpp

main.cpp:11: error: ‘QWebView’ has not been declared

main.cpp:18: error: ‘QWebSettings’ has not been declared
main.cpp:19: error: ‘QWebSettings’ has not been declared
main.cpp:20: error: ‘QWebSettings’ has not been declared
main.cpp: In function ‘int main(int, char**)’:

main.cpp:42: error: expected type-specifier before ‘QWebView’
main.cpp:42: error: expected `;' before ‘QWebView’
make: *** [main.o] Error 1

I have the web kit on my Fedora Core 10 machine:
qt-4.5.3-9.fc10.i386
qt-devel-4.5.3-9.fc10.i386

Thanks all for any help

    The error message indicates that the compiler cannot find what you’re trying to include, i.e. <QWebView>. The way to tell the compiler where to look is with the -I flag, to specify include directories (these are not recursive).

    Currently, you set the following include dirs:

    • -I/usr/lib/qt4/mkspecs/linux-g++
    • -I.
    • -I/usr/include/QtCore
    • -I/usr/include/QtGui
    • -I/usr/include

    You need to find where QWebView is located on your system, and add the include path to the commandline (or install QWebView into one of the above dirs).

    General note: When you get a lot of errors like this, focus on the first one or two. The later errors (such as ‘QWebView’ has not been declared) will probably be solved by fixing the missing-include error.
