Here is how to build NetPBM (pbmPlus) 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 netpbm/iX... :hello lars,manager.sys :newlink /usr/local/netpbm , /IX/NETPBM Create user and MPE group to provide netpbm/iX "home" setup... :hello lars,mgr.ix :newgroup netpbm.ix ;access=(r,w,a,l,x,s:GL) :newuser netpbm.ix ;pass=dontknow :altuser netpbm.ix ;home=netpbm ;cap=+ph,gl Logon as NetPBM.iX user to unpack files and perform build... :hello lars,netpbm.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/tiff-v3.4-tar.gz | tar xvof - And then add the MPE specific files (into separate mpe subdir)... shell/iX> tar xvzopf /tmp/lt-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 tiff-v3.4 shell/iX> ./configure shell/iX> make shell/iX> make install shell/iX> make distclean shell/iX> cd .. That's all (you'd also have this state by unpacking lt-all.tar.Z) shell/iX> exit :bye
