Yes, Only n64. I got a mips64(mipsIII) computer, but it's slow, so I'm trying to cross build a n64 bit gentoo for it, the first step is a n64 gcc and glibc. I've successfully build a multilib cross toolchain manually on a x86_64 host, it support o32, n32 and n64. but I prefer a n64 only toolchain, and then a n32/o32 only toolchain. > > 1. set PORTATE_OVERLAY in /etc/make.conf > > > > echo "PORTDIR_OVERLAY=/usr/local/portage" >> /etc/make.conf > > OK > > > 2. emerge crossdev > > > > emerge -av crossdev > > OK > > > 3. select CTARGET (mips64el for instance here), Setup 'categories', set > > proper package/use mask > > why did you install crossdev only to turn around and not use it ? all of > these manual steps you invoked crossdev does for you. in fact, it's > obvious you read the file on my dev.g.o space but completely ignored the > first paragraph which said *use crossdev, dont do this by hand*.
I used to use crossdev but it always fail, so this time I'm doing it step by step, also I need tune some important USE flags (such as n32,n64, or altitec), and I'm not sure how to do it using crossdev. Thanks for your great document:) BTW: even I edit /etc/profile/* mannually, crossdev will still append to that file and sounds like ignore my settings. > please undo the things you've done by hand, unmask the n64 flag in > your /etc/portage dir like you showed, and then just run: > crossdev -t mips64el-unknown-linux-gnu I've did `crossdev -s4 -S -t mips64el-unknown-gnu', and I expect it will produce a n64 (could do -mabi=64) toolchain and libc, but it could only produce 32bit binary, and I'm not sure it's n32 or o32. > if you want specific versions, then use the options to crossdev > -mike Thanks very much for help.
