Hello,Xudong<br> I tried to install mpich2 serveral days ago,I think I got similiar problems:<br><br># mp32-mpicc <br>/usr/lib/gcc/i386-redhat-linux/4.3.0/../../../crt1.o: In function `_start':<br>(.text+0x18): undefined reference to `main'<br>collect2: ld 返回 1<br><br> I asked the question at another website(redhat bugzilla),who told me that it's just ok and I do not need to worry about it. Indeed when I try to use it to compile and run a simple test program,it seems work fine. I also want to make sure whether it's true or not.<br>------------------------------------------------------------<br><br><div>&nbsp;</div><div>&nbsp;</div><div>&nbsp;</div><div>&nbsp;</div><pre>在2008-06-04，"倪旭东" &lt;xd_ni@seu.edu.cn&gt; 写道：<br>>Hello,mpich-discuss:<br>> I'm a beginner of MPICH,and after I install MPICH.
