That means that if PKGBUILDs do actually define different src_platforms (although the main use case I can think of for that is where you're actually downloading a binary), to get them to build on pentium4 architecures, as well as adding 'pentium4' to the arch variable, you also need to rename src_i686 as src_pentium4.
]]>Of course, straight i686 code with no sse/mmx instrcuctions will work on pretty much any post-pentium pro machine, but it may not run quite as well.
]]>1. Change the line from makepkg.conf to:
CFLAGS="-march=i686 -mtune=generic -O2 -pipe -fno-plt"etc
2. edit the PKGBUILD:
arch=('i686' 'pentium4')
After that he makes a Pentium4 package which I can install.
Thanks for the food for thought!
