I have some C code originally developed on linux, which makes use of gengetopts to parse the command line. I also want to build that code on cygwin.
(On linux I simply did "apt-get install gengetopt" and everything was fine.
I don't find any package that looks like gengetopt on cygwin, so I try to build from source as per the instructions.
But when I try:
I first get an error that I have to fix with dos2unix, and then this:
$ sh ./configure.ac ./configure.ac: line 18: dnl: command not found ./configure.ac: line 19: syntax error near unexpected token `GNU' ./configure.ac: line 19: `AC_INIT(GNU gengetopt,2.23)'
The relevant lines in the config file are:
dnl Process this file with autoconf to produce a configure script. AC_INIT(GNU gengetopt,2.23)
I did make sure that autoconf, bison, flex and m4 are installed. The default shell in cygwin seems to be bash. What is the problem? what is "dnl" - seems to be a linux built in. If so why is it not part of cygwin?
Is there an easier way to do this? it all looks like a bit of a compatibility mess. Is it generally this hard to install packages on cygwin?
