我在 Centos.EL7 上编译 meshlab-2016.12 时遇到问题。
我得到了一些方法。
将 QT 更新为 Qt-5.9.1，因为 Centos 上的最新版本是 Qt 版本 5.6.1 - 我之前安装过
sudo yum install qt5-qtbase
sudo yum install qt5-qtx11extras
sudo yum install qt5-qtbase-devel
但是，meshlab 至少需要 Qt5.7
然后设置这些环境。变量
setenv QTDIR /usr/local/Qt-5.9.1
setenv QTINC /usr/local/Qt-5.9.1/include
setenv QTLIB /usr/local/Qt-5.9.1/lib
setenv PATH /usr/local/Qt-5.9.1/bin:$PATH
setenv PATH /usr/local/bin:/usr/local/Qt-5.9.1/bin:$PATH
然后按照测试机器上的说明安装到 /opt/TESTING
将 vcglib 安装到 /opt/TESTING
将 meshlab-2016.12 下载到 /opt/TESTING 并在那里解压
跑了以下
qmake-项目
（这会选择正确版本的 QT）
qmake src/external/external.pro
（制作外部库 - 包括 jhead-2.95
gmake
gmake install
（制作外部库 - 包括 jhead-2.95 ）
qmake src/meshlab_mini.pro
（使用最少的插件集构建 meshlab ）
这就是失败的地方，如下所示；
../../vcglib/vcg/complex/algorithms/clean.h:1789:0:

所以说ld找不到ljhead。编译的其他部分似乎确实可以找到它，例如
-I../src/external/glew-1.7.0/include -I../src/external/jhead-2.95
看着ld
/bin/ld -V
GNU ld version 2.25.1-22.base.el7

在这一点上，任何建议都会很有用。希望我只是错过了一些东西
更新：尝试了下面 William Brown 的解决方法，取得了一些进展。后来失败了
