Question

我正在尝试在Qt Creator中创建的应用程序中使用QJson库。操作系统是Ubuntu 12.04 32位。

我使用了synaptic来安装libqjson0（0.7.1-6）。该库已安装在

中

/usr/lib/i386-linux-gnu/libqjson.so.0
/usr/lib/i386-linux-gnu/libqjson.so.0.7.1

我尝试通过右键单击我的项目并选择“添加库...”将库添加到Qt Creator。当我输入上面显示的2个路径中的任何一个时，文件名为红色，表示它不正确。我创建了一个链接到libqjson.so.0.7.1的符号链接 libqjson.so 。我现在可以使用/usr/lib/i386-linux-gnu/libqjson.so路径添加库。

现在对于noob问题：在应用程序的顶部我添加了#include＆lt; parser.h＆gt;。我得到一个错误'parser.h：没有这样的文件或目录。我在/ usr / libs / i386-linux-gnu中搜索了parser.h并且没有返回任何结果。我需要在parser.h之前添加一些东西吗？还是我错过了其他东西？

Answer 1

您还需要 libjson-dev 包。基于deb的分发版通常在* -dev包中提供包含文件。

安装完成后，你会在/ usr / include / qjson中找到parser.h和其他标题。

Answer 2

.pro文件中缺少这些行：

INCLUDEPATH += folderwhereisinstalled/qjson/include

LIBS += -Lfolderwhereisinstalled/qjson/lib -lqjson

在Ubuntu下的Qt Creator中使用QJson库
