如何在qt中添加taglib库？ubuntu环境下

[apoorcowboy]

我先对库运行了
sudo ./configure
sudo make
sudo make install

然后如何在qtcreator的工程中引用这个库？
也就是说如何修改.pro文件
和如何包含这个库的头文件？

求解阿，救命啊

自己解决，散分

Ok, I seem to have got this figured out. We need to include the location of the header files in the compiler options. Effectively we need to have something like

g++ something something -I /usr/include/taglib yada yada.

i.e. in the Makefile. We also need to have -ltag included as a link.

Effectively, in the Makefile, this is what it translates to:

CXXFLAGS = -pipe -I /usr/include/taglib -I /usr/include/taglib-extras -g -D_REENTRANT -Wall -W $(DEFINES)
LIBS = $(SUBLIBS) -L/usr/lib -ltag -lQtGui -lQtCore -lpthread

(note the -ltag in the LIBS variable, taglib-extras in CXXFLAGS might not be required)

and if you compile it now with make, you'll find everything compiling fine.

In qt-creator, these values can be set by editing the .pro file of your project and adding in the following variables:

QMAKE_CXXFLAGS += -I /usr/include/taglib -I /usr/include/taglib-extras
QMAKE_LIBS += -ltag

This will make the necessary modifications to the Makefile when you build the project.

I hope someone finds this useful. It took me a day of googling, searching on ubuntu forums and a helpful dev at #qt-creator on freenode to figure this out.

Cheers!

你那个库安装不知道合不合格啊，我记得我以前安装libnet库时貌似需要加一个--prefix=/usr选项的
在库已近装好之后，.pro文件中加入LIBS+=库名即可
