Build 在Ubuntu 16.04上构建最新版本的腮腺炎5.2.1

按照tarball顶部目录中安装文件的说明， 我执行

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

然后我跑去做。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

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

他们每个人都跑完了。只有示例没有编译 以下命令均无效。他们都失败了，但都有相同的错误

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-

/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

我安装了所有这些包含blacs的软件包，但仍然不起作用

   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

---

接下来要做什么？

tarball中的examples目录有自己的Makefile。 它从顶级目录导入Makefile.inc

原始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。 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目录包含所有构建的可执行示例
