1. 方式一

• 在 Qt 项目名称上右键，选择 Add Library，弹出以下界面，手动选择 Library file和 Include path；

• 配置完成后，.pro文件相关内容如下：

LIBS += -lX11

unix:!macx:
LIBS += -L$$PWD/../../../../../../../../opt/halcon/lib/x64-linux/ -lhalcon
LIBS += -L$$PWD/../../../../../../../../opt/halcon/lib/x64-linux/ -lhalconc
LIBS += -L$$PWD/../../../../../../../../opt/halcon/lib/x64-linux/ -lhalconcpp
LIBS += -L$$PWD/../../../../../../../../opt/halcon/lib/x64-linux/ -lhalconcppxl
LIBS += -L$$PWD/../../../../../../../../opt/halcon/lib/x64-linux/ -lhalconcxl
LIBS += -L$$PWD/../../../../../../../../opt/halcon/lib/x64-linux/ -lhalconxl
LIBS += -L$$PWD/../../../../../../../../opt/halcon/lib/x64-linux/ -lhdevenginecpp
LIBS += -L$$PWD/../../../../../../../../opt/halcon/lib/x64-linux/ -lhdevenginecppxl

INCLUDEPATH += $$PWD/../../../../../../../../opt/halcon/include
INCLUDEPATH += $$PWD/../../../../../../../../opt/halcon/include/halconcpp
DEPENDPATH += $$PWD/../../../../../../../../opt/halcon/include

• 后面使用的时候直接 copy 过去即可。

2. 方式二

将 halcon 添加到环境变量，在 ~/.bashrc中添加如下内容：

HALCONARCH=x64-linux; export HALCONARCH
HALCONROOT=/opt/halcon; export HALCONROOT
HALCONEXAMPLES=${HALCONROOT}/examples; export HALCONEXAMPLES
HALCONIMAGES=${HALCONROOT}/examples/images; export HALCONIMAGES
PATH=${HALCONROOT}/bin/${HALCONARCH}:${HALCONROOT}/FLEXlm/${HALCONARCH}:${PATH}
export PATH
if [ ${LD_LIBRARY_PATH} ] ; then
LD_LIBRARY_PATH=${HALCONROOT}/lib/${HALCONARCH}:${LD_LIBRARY_PATH}
export LD_LIBRARY_PATH
else
LD_LIBRARY_PATH=${HALCONROOT}/lib/${HALCONARCH}; export LD_LIBRARY_PATH
fi
if [ "x${FLEXID_LIBRARY_PATH}" = "x" ]; then
FLEXID_LIBRARY_PATH="${HALCONROOT}/FLEXlm/${HALCONARCH}/flexid9:/usr/lib"
export FLEXID_LIBRARY_PATH
fi

在.pro文件中直接配置：

INCLUDEPATH += "$HALCONROOT/include"
INCLUDEPATH += "$HALCONROOT/include/halconcpp"

unix:LIBS += -lhalcon -halconcpp -lX11
