source pack在unbuntu安装问题

[CjjJoy]

大家好，我之前尝试在unbuntu系统上安装source pack 遇到点问题，后来我按照https://openfoam.org/download/5-0-ubuntu/链接中的办法成功安装了openfoam5,之后在src/regionModel中做了些小改动编译也没有问题。
现在我尝试将reactingParcelFilmFoam中的reactingCloud改成sprayCloud生成一个新的求解器，编译的时候出现了以下错误，与之前source pack安装的错误一致：

     -lm -o /opt/openfoam5/platforms/linux64GccDPInt32Opt/bin/sprayFilmFoam

make: *** [/opt/openfoam5/platforms/linux64GccDPInt32Opt/bin/sprayFilmFoam] Error 1

不知道大家有没有什么建议？谢谢！

我猜测你这个是源代码没写对，或者拷贝复制的时候丢了代码，undefined reference这种错误只是在编译类后捆绑到求解器的时候函数没定义导致。可能你代码里面有些函数代码块丢失了。

以上只是猜测，因为不清楚你安装的详细过程不能确诊。
