答案：
Since 3.2, LAPACK moved to fortran 90 standard, so you cannot use g77
to build the library anymore. gfortran, g95 are fine.
For more details on LAPACK 3.2 release, please read the
http://www.netlib.org/lapack/lapack-3.2.html
Let me know if you have any other question.
Sincerely
Julie Langou
You can not compile LAPACK with g77. (This is true since 3.2).
You can use gfortran for example.

最后重新下载安装了gfortran，就安装好了。

I.e. you might need libg2c.so (libg2c.a?) installed on your machine. [On
our 64 bit Fedora Core 6 (AMD Opteron) the rpm file is ‘compat-libf2c’.]
But once you have your code running you probably want to either
compile faster BLAS and LAPACK libraries or use ones provided by hardware
or compiler vendors: In this case you probably could use the MKL libraries
by Intel. Then you don’t need to bother with this issue of linking.
查看make的指令实际是这样的：
mpif90 -o /home/duanple/scalapack/scalapack-1.8.0/TESTING/xdscaex pdscaex.o pdscaexinfo.o /home/duanple/scalapack/scalapack-1.8.0/libscalapack.a /home/duanple/scalapack/BLACS/LIB/blacs_MPI-LINUX-0.a /home/duanple/scalapack/BLACS/LIB/blacsCinit_MPI-LINUX-0.a /home/duanple/scalapack/BLACS/LIB/blacsF77init_MPI-LINUX-0.a /home/duanple/scalapack/BLACS/LIB/blacs_MPI-LINUX-0.a /home/duanple/scalapack/lapack-3.2.1/lapack_LINUX.a /home/duanple/scalapack/lapack-3.2.1/blas_LINUX.a /home/duanple/intel/ict/3.0.1/mpi/3.0/lib/libmpi.a
一。这样添加上-lg2c
mpif90 -lg2c -o /home/duanple/scalapack/scalapack-1.8.0/TESTING/xdscaex pdscaex.o pdscaexinfo.o /home/duanple/scalapack/scalapack-1.8.0/libscalapack.a /home/duanple/scalapack/BLACS/LIB/blacs_MPI-LINUX-0.a /home/duanple/scalapack/BLACS/LIB/blacsCinit_MPI-LINUX-0.a /home/duanple/scalapack/BLACS/LIB/blacsF77init_MPI-LINUX-0.a /home/duanple/scalapack/BLACS/LIB/blacs_MPI-LINUX-0.a /home/duanple/scalapack/lapack-3.2.1/lapack_LINUX.a /home/duanple/scalapack/lapack-3.2.1/blas_LINUX.a /home/duanple/intel/ict/3.0.1/mpi/3.0/lib/libmpi.a
仍然有如下错误：

collect2: ld 返回 1
make: *** [pdscaex] 错误 1
二。原因有了，解决方案大概如下：
Hi,
I’m replying to my own message, as I have found a
dirty trick to bypass the problem.
At final linking stage of my code, I add the file
BLACS/SRC/MPI/INTERNAL/bi_f77_get_constants.o
to the list of object files and libraries.
Then the problem of the undefined reference is solved.
For some strange reason, this object file doesn’t make it into
the blacs library files.
简单来说就是链接时直接加上这个文件：bi_f77_get_constants.o
mpif90 -lg2c -o /home/duanple/scalapack/scalapack-1.8.0/TESTING/xdscaex pdscaex.o pdscaexinfo.o /home/duanple/scalapack/scalapack-1.8.0/libscalapack.a /home/duanple/scalapack/BLACS/LIB/blacs_MPI-LINUX-0.a /home/duanple/scalapack/BLACS/LIB/blacsCinit_MPI-LINUX-0.a /home/duanple/scalapack/BLACS/LIB/blacsF77init_MPI-LINUX-0.a /home/duanple/scalapack/BLACS/LIB/blacs_MPI-LINUX-0.a /home/duanple/scalapack/lapack-3.2.1/lapack_LINUX.a /home/duanple/scalapack/lapack-3.2.1/blas_LINUX.a /home/duanple/intel/ict/3.0.1/mpi/3.0/lib/libmpi.a /home/duanple/scalapack/BLACS/SRC/MPI/INTERNAL/bi_f77_get_constants.o
三。bi_f77_get_constants__没了，仍然有：
pdscaex.o: In function `MAIN__’:
pdscaex.f:(.text+0x4d): undefined reference to `blacs_pinfo_’
pdscaex.f:(.text+0xca): undefined reference to `blacs_get_’

pdscaex.f:(.text+0x114): undefined reference to `blacs_gridinfo_’
pdscaex.f:(.text+0x14a): undefined reference to `blacs_exit_’
pdscaex.f:(.text+0x590): undefined reference to `blacs_gridexit_’

Hi. I’ve been looking into this as well. I think the issue might simply
be with the default output bufferring in gfortran. I’d also like to know
what you are observing, but maybe you can simply try:
export GFORTRAN_UNBUFFERED_ALL=y
and then trying the tests? When building blacs, I also set the following
in my Bmake.inc file:
INTFACE = -DAdd_
TRANSCOMM = -DCSameF77
This was specifically for the case where I built MVAPICH2 0.9.8 with
F77=gfortran and F90=gfortran.
Does any of this help solve the problem you are having?

也就是要注意这几项设置。重新编译下blacs
实际上最根本的原因，是因为在编译BLACS LAPACK Scalpack的时候，没有设置相同的fortran编译器,开始lapack必须用gfortran编译器，但是编译blacs的时候使用了g77，最后编译scalapack的时候又使用了mpif90
后来重新调整了各个*.inc的设置，BLACS LAPACK均使用gfortran，scalapack是用mpif90,最后再在scalapack里make exe就没有出现任何错误了。
