makefile - 使用 -fPIC 重新编译

Question

我有 MPICH 3.0.4安装在我的机器上(Ubuntu 12.04)。我正在尝试安装一个名为 Qthreads 的库我之前使用过并成功安装过它(除了安装了 MPICH2 包)。配置工作正常:
./configure --prefix=/usr/local/qthreads --enable-multinode --with-multinode-runtime=mpi --with-portals4=/usr/local/portals4 --with-hwloc=/usr/local/hwloc :

...
...
...
System Characteristics:
       Target Style: unix
         Multi-node: yes, mpi
       Topology API: hwloc
        Qtimer type: clock_gettime
     Aligned_t size: 8 (aligned on 8 byte boundaries)
 Default Stack size: 4kB

Safety/Debugging:
   Sanity assert()s: no
    Check alignment: no
          Profiling: none
   Debugging Output: no
        Guard Pages: no

Speed:
          Scheduler: sherwood (multiworker shepherds)
         Sinc Style: donecount
      Barrier Style: feb
   Dictionary Style: simple
    Lazy Thread IDs: yes
       Pools/caches: memory, spawns
            RCRTool: no
Increments/CAS/FEBs: Compiler Builtin (both), lock-based hash

当我尝试运行时 make ，我收到以下错误:

  ...
  ...
  ...
  CCLD     libqthread.la
/usr/bin/ld: /usr/local/lib/libmpich.a(barrier.o): relocation R_X86_64_32 against `MPIR_ThreadInfo' can not be used when making a shared object; recompile with -fPIC
/usr/local/lib/libmpich.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
make[2]: *** [libqthread.la] Error 1
make[2]: Leaving directory `/home/alex/Downloads/qthread-1.9/src'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/alex/Downloads/qthread-1.9/src'
make: *** [all-recursive] Error 1

我有 looked around似乎显而易见的(也是唯一可能的)解决方案是按照编译器所说的去做:用 -fPIC 重新编译.但是，我对检查和编辑 Qthreads 的任何 Makefile 犹豫不决，因为它们又长又复杂。是否有一种简单的方法可以使用 -fPIC 重新编译?

请指教。我感谢任何输入。

在所有讨论之后，我用 --enable-shared 全新安装了 MPICH 3.0.4。是唯一给出的配置选项。出于某种原因，它成功编译和构建，尽管之前没有这样做。完成此操作后，无需任何额外选项即可成功配置和构建 Qthreads。
