c++ - 语法错误 : EOF in backquote substitution make: *** [mainwindow. o] 错误 2

Question

我正在尝试编译从 Git hub 下载的 Qt 项目。我在编译过程中遇到了以下错误。

/bin/sh: 1: 语法错误:反引号替换中的 EOF
make: * [mainwindow.o] 错误 2
****08:33:27:进程“/usr/bin/make”退出，代码为 2。
构建/部署项目 FiniteElements 时出错(套件:桌面)
执行步骤'Make'时******

我的.pro文件如下，

QT       += core gui opengl widgets
DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x000000`
TARGET = FiniteElements
TEMPLATE = app

LIBS += -lqwt

INCLUDEPATH += "/usr/include/qwt/"



SOURCES += main.cpp\
        mainwindow.cpp \
    FiniteElements.cpp \
    graph_plot.cpp

HEADERS  += mainwindow.h \
    FiniteElements.h \
    graph_plot.h

谁能帮帮我？

在安装了 qt5-default 5.5.1+dfsg-16ubuntu7 和 libqwt-qt5-dev 6.1.2-5 的 Ubuntu 16.04.1 LTS 上测试的说明:

克隆 repo :

$ git clone https://github.com/MKrishtop/FiniteElements.git

从 Qt 4 到 Qt 5 的端口:

$ cd FiniteElements/
$ find . -type f -exec sed -i 's/QtGui/QtWidgets/g' {} \;
$ find . -type f -exec sed -i 's/toAscii/toLocal8Bit/g' {} \;
$ sed -i 's/-lqwt/-lqwt-qt5/g' FiniteElements.pro
