本文主要是介绍centos7 Qt5.9.1 opencv静态库报grfmt_exr.cpp错误，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

错误：

grfmt_exr.cpp:-1: error: undefined reference to `Imf::Chromaticities::Chromaticities(Imath::Vec2<float> const&, Imath::Vec2<float> const&, Imath::Vec2<float> const&, Imath::Vec2<float> const&)'

grfmt_exr.cpp:-1: error: undefined reference to `Imf::globalThreadCount()'

1.centos7 编译opencv2.4.13静态库的方法参考：http://blog.csdn.net/sz76211822/article/details/75592973

2.环境配置：

2.1在终端里面输入 locate libIlmImf

将libIlmImf.a 拷贝出来。如下面的“工程目录”

2.2将opencv Include文件夹以及静态库从 /usr/local/lib 拷贝出来.

工程目录：

静态库目录：

3.Qt5.9.1 配置Opencv静态库

INCLUDEPATH += -L$$PWD ./Opencv/include \-L$$PWD ./Opencv/include/opencv \-L$$PWD ./Opencv/include/opencv2 \LIBS +=-ljpeg \
-lpng \
-ljasper \
-ltiff \
-ldl \
-lz \
$${PWD}/Include/Sqlite3/libsqlite3.a \
$${PWD}/Include/Opencv/lib/libopencv_core.a \
$${PWD}/Include/Opencv/lib/libopencv_highgui.a \
$${PWD}/Include/Opencv/lib/libopencv_imgproc.a \
$${PWD}/Include/Opencv/lib/libIlmImf.a \

重新编译，错误就没有了
