configure get error in AIX(ksh)

[poohRui]

While I run this commond in parallel-netcdf-1.10.0

./configure --prefix=/gza/u/xiaohui/g6/code_test/PnetCDF --host power

I got this error

checking if Fortran compiler is NAG... ./configure[28135]: conftest.ver: bad file unit number

and can not get makefile so on I wonder how to solve it Thank you!

The error message indicates your MPI Fortran compiler has a problem with command-line argument -V. Please provide the link to your config.log file and I will take a look.

I have never tested PnetCDF on ksh. It appears that ksh's stdout and stderr redirection is different from bash.

I think you mean this file. Here is the link: https://github.com/poohRui/someIssues/blob/master/acinclude.m4

Yes.

It appears ksh does not work well with automake. A bug report of configure hanging can be found in https://lists.gnu.org/archive/html/bug-automake/2015-04/msg00000.html

[poohRui]

Thank you! After I changed the shell to bash, The error disappeared.

Close this issue, as ksh is not supported. It can be reopened, if ksh is to be supported in the future.
