Porting a library with no config.sub file or without configure script

[M. B.]

Hello,

Sorry if this is a silly question - I am just learning to use NaCl and I haven't found answers here that answer my question.

I am trying to port the C++ NTL library . The problem is, that although there is a configure script included, there is no config.sub file. 

Running 

TOOLCHAIN=glibc NACL_ARCH=x86_64 ~/webports/src/build_tools/nacl-configure.sh ./configure

from the packages' src/ directory fails with:

Failed to find patch 0 location in configure script: ./configure
Failed to find patch 1 location in configure script: ./configure
Failed to find patch 2 location in configure script: ./configure
Failed to find config.sub (./config.sub).
Please specify using $CONFIG_SUB.

Can you please point me in the right direction on how to proceed? 

Also, I have another library that doesn't even have a configure script, but has a Makefile. Will I still be able to port it?

Best regards,

M.B.

I believe the autotools will add config.sub for you. Often the generated files are checked in, but sometimes they aren't and automake will need to be run.

I found this link, which seems related: https://lists.gnu.org/archive/html/autoconf/2012-01/msg00001.html

Did you try adding CONFIG_SUB_MISSING=1 ?

you may also be able to (re)generate one with autoreconfig
