我正在跟着本Webtoolkit教程:https://www.webtoolkit.eu/wt/doc/tutorial/wt.html
我正在虚拟机上的Rasbian / Debian上运行所有这些程序,并且正在使用C ++ 14
我决定将hello.cpp代码复制粘贴到我的桌面上,并在终端上像这样编译它,因为我面临链接错误,因此在教程中跟随命令行示例:
g++ -std=c++14 -o hello hello.cpp -I/usr/include -L/usr/lib
但是我仍然得到:
hello.cpp:1:29: fatal error: Wt/WApplication.h: No such file or directory
#include <Wt/WApplication.h>
我的Wt文件位于/ usr / include和/ usr / lib中,这就是我使用它们的原因。
此stackoverflow无法解决我的问题:How to Install Wt into a Custom Folder Without "fatal error: Wt/WApplication: No such file or directory"
编辑:我能够运行/ usr / lib / Wt / examples中Wt文件夹中的示例文件,但无法在桌面上运行,我按照教程中的命令行示例链接错误>
编辑2:如果有帮助,请使用cpp代码,与教程相同,只需复制粘贴即可:
#include <Wt/WApplication.h>
#include <Wt/WBreak.h>
#include <Wt/WContainerWidget.h>
#include <Wt/WLineEdit.h>
#include <Wt/WPushButton.h>
#include <Wt/WText.h>
class HelloApplication : public Wt::WApplication
{
public:
HelloApplication(const Wt::WEnvironment& env);
private:
Wt::WLineEdit *nameEdit_;
Wt::WText *greeting_;
};
HelloApplication::HelloApplication(const Wt::WEnvironment& env)
: Wt::WApplication(env)
{
setTitle("Hello world");
root()->addWidget(std::make_unique<Wt::WText>("Your name, please? "));
nameEdit_ = root()->addWidget(std::make_unique<Wt::WLineEdit>());
Wt::WPushButton *button = root()->addWidget(std::make_unique<Wt::WPushButton>("Greet me."));
root()->addWidget(std::make_unique<Wt::WBreak>());
greeting_ = root()->addWidget(std::make_unique<Wt::WText>());
auto greet = [this]{
greeting_->setText("Hello there, " + nameEdit_->text());
};
button->clicked().connect(greet);
}
int main(int argc, char **argv)
{
return Wt::WRun(argc, argv, [](const Wt::WEnvironment& env) {
return std::make_unique<HelloApplication>(env);
});
}

Wt包含文件在某些操作系统上不具有.h扩展名。
尝试while True:
collectEyesBlade = raw_input(
"\nEnter desired blade number: ")
if collectEyesBlade in [range(0,9)]:
break
elif collectEyesBlade.lower() == 'q':
return
else:
print "\nInvalid input. Enter value between 0 and 9, or 'q' to quit"
continue
#include <Wt/WApplication>
答案 1 :(得分:0)
因此无需扩展名即可使用:
#include <Wt/WApplication>
答案 2 :(得分:0)
尝试:
g++ -std=c++14 -o hello hello.cpp -I/usr/local/include/Wt -L/usr/local/lib64/
OR
g++ -std=c++14 -o hello hello.cpp -I/usr/local/include/Wt -L/usr/local/lib/
