我正在尝试使用 makefile 在 Linux+openmpi 上编译一个程序，但出现了这个错误：我已经查看了类似问题的答案，但仍然可以修复它。
/usr/bin/ld: outseis.o: undefined reference to symbol 'trunc@@GLIBC_2.2.5'
/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../x86_64-linux-gnu/libm.so: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
make: *** [sofi2D] Error 1
下面是 makefile：我怀疑它与缺少的库有关，但似乎找不到如何解决。
