I’m trying to compile mira 3.4.1 on a cluster computer with suse 10 Linux system. We’ve upgraded boost and flex to the latest version before compiling. Since I do not have the administrator authority, necessary libs were installed under $Home/software. The locations of the newly-installed libs were informed using option switches as listed below: “./configure --prefix=/public/home/zhaozengfang/software/mira --with-boost=/public/home/zhaozengfang/software/boost148/ --with-boost-libdir=/public/home/zhaozengfang/software/boost148/lib/ --with-tcmalloc-dir=/public/home/zhaozengfang/software/gperf/lib --enable-64=yes --enable-mirastatic”. It seems OK for this step说明: http://seqanswers.com/forums/images/smilies/smile.gif. The system reported that everything looks good. However, during make step, several errors occurred.说明: http://seqanswers.com/forums/images/smilies/confused.gif I failed to install mira on the cluster computer.

I’ve tried my best to fix the problem including add the new libs into environmental variables, but still failed说明: http://seqanswers.com/forums/images/smilies/mad.gif. The config.log are ready, I will email it to you if needed. I’m grateful if you can give me some help. By the way, how to activate MPI mode in Mira. I’d like to use 20 cpus for assembling as my dataset is really huge. Thanks a lot!
