在Ubuntu 16.04上构建最新版本的MUMPS 5.2.1

Question

按照tarball顶层目录中的安装文件中的说明，我执行了

cp Make.inc/Makefile.debian.PAR ./Makefile.inc

然后我运行make。但是，我遇到了以下错误。

make[1]: Entering directory '../MUMPS_5.2.1/examples'
mpif90 -O -fopenmp  -I. -I../include -I../src -c dsimpletest.F -o dsimpletest.o
mpif90 -o dsimpletest -O -fopenmp dsimpletest.o  ../lib/libdmumps.a ../lib/libmumps_common.a

//usr/lib/libblacs-openmpi.so.1: error adding symbols: DSO missing from command line

make[1]: *** [dsimpletest] Error 1
make[1]: Leaving directory '/.../MUMPS_5.2.1/examples'
Makefile:52: recipe for target 'dexamples' failed
make: *** [dexamples] Error 2

为了找出错误的根源，我依次尝试了每种精度

make s     # single precision real
make d     # double precision real
make c     # complex
make z     # double complex

他们中的每一个都跑到完成了。这只是没有编译的示例，下面的命令都不起作用。它们都由于相同的错误而失败。

make sexamples
make dexamples
make cexamples
make zexamples

常见错误：

mpif90 -o dsimpletest -O -fopenmp dsimpletest.o  ../lib/libdmumps.a ../lib/libmumps_common.a   
-L/usr/lib  -lmetis -L../PORD/lib/ -lpord -L/usr/lib -lesmumps -lscotch -lscotcherr -lscalapack- 
openmpi -llapack  -lblas -lpthread
/usr/bin/ld: ../lib/libdmumps.a(dend_driver.o): undefined reference to symbol 'blacs_gridexit_'
//usr/lib/libblacs-openmpi.so.1: error adding symbols: DSO missing from command line

我安装了所有包含blacs的包，但是仍然不能工作。

   sudo apt install libscalapack-openmpi1
   sudo apt install libscalapack-mpi-dev
   sudo apt install libblacs-mpi-dev
   sudo apt install libblacs-openmpi1
   sudo apt install blacs-mpi-test blacs-test-common

下一步要做什么？

Answer 1

tarball中的examples目录有自己的Makefile。它从toplevel目录导入Makefile.inc

原始的Makefile.inc

LIBBLAS = -lblas
LIBOTHERS = -lpthread

如果您已经安装了上面所有的blacs包，那么您的/usr/lib将如下所示

 find . -iname "*blacs*"
./libblacs-openmpi.so.1.1
./libblacsF77init-openmpi.a
./libblacsCinit-openmpi.so.1
./libblacsF77init-openmpi.so.1
./blacs
./blacs/fblacs_test_shared-openmpi
./blacs/cblacs_test_shared-openmpi
./blacs/fblacs_test_static-openmpi
./blacs/cblacs_test_static-openmpi
./libblacsCinit-openmpi.a
./libblacs-openmpi.a
./libblacsCinit-openmpi.so.1.1
./libblacsF77init-openmpi.so.1.1
./libblacs-openmpi.so
./libblacsF77init-openmpi.so
./libblacsCinit-openmpi.so
./libblacs-openmpi.so.1

将Makefile.inc中的行更改为

LIBBLAS   = -lblas
LIBOTHERS = -lpthread -lblacs-openmpi

一切都开始为我工作了。执行的编译器命令现在是

mpif90 -o dsimpletest -O -fopenmp dsimpletest.o  ../lib/libdmumps.a ../lib/libmumps_common.a    
-L/usr/lib  -lmetis -L../PORD/lib/ -lpord -L/usr/lib -lesmumps -lscotch -lscotcherr -lscalapack-
openmpi -llapack  -lblas -lpthread -lblacs-openmpi

..。与没有-lblacs-openmpi链接器命令的原始命令相反。

现在，examples目录包含了所有构建的可执行示例。
