Here is how to build GNU autoconf for MPE/iX
--------------------------------------------

Create the IX account, if it does not exist yet...

 :hello manager.sys

 :newacct ix,mgr ;pass=dontknow

 :altacct ix ;cap=+ph
 :altuser mgr.ix ;cap=+ph

 :altgroup pub.ix ;access=(r,x:any;w,a,l,s:AL)


Create symbolic link for HFS name to the "home" of autoconf/iX...

 :hello lars,manager.sys

 :newlink /usr/local/autoconf , /IX/AUTOCONF


Create user and MPE group to provide autoconf/iX "home" setup...

 :hello lars,mgr.ix

 :newgroup autoconf.ix ;access=(r,w,a,l,x,s:GL)

 :newuser autoconf.ix ;pass=dontknow

 :altuser autoconf.ix ;home=autoconf ;cap=+ph,gl


Logon as AutoConf.iX user to unpack files and perform build...

 :hello lars,autoconf.ix

 (optionally copy some helpful .exrc and .profile files here)

 :/bin/sh -L


First unpack the original GNU autocinf 2.12 distribution...

 shell/iX> gunzip -c /tmp/autoconf-2.12.tar.gz | tar xvof -


And then add the MPE specific files (into separate mpe subdir)...

 shell/iX> tar xvzopf /tmp/ac-mpe.tar.Z

 shell/iX> cat ReadMe


Now have the setup script replace/adjust the MPE specific files...

 shell/iX> sh mpe/setup


Finally perform the configure, make and make install steps...

 shell/iX> cd autoconf-2.12

 shell/iX> ./configure --prefix=/usr/local/autoconf

 shell/iX> make

 shell/iX> make install

 shell/iX> make distclean

 shell/iX> cd ..


Optionally create a subdirectory with HTML docs (needs texi2html)...

 shell/iX> umask 0022   
 shell/iX> mkdir public_html
 shell/iX> cd public_html

 shell/iX> texi2html -verbose -split_chapter ../autoconf-2.12/autoconf.texi

 shell/iX> texi2html -verbose -split_chapter ../autoconf-2.12/standards.texi

 shell/iX> cd ..


That's all (you'd also have this state by unpacking ac-all.tar.Z)

 shell/iX> exit
