Apparently 32 MB is > not enough for a new kernel compilation. Remove the "-pipe" option from CFLAGS and COPTFLAGS in your /etc/make.conf file. That will serialize compiler stages that normally run in parallel, so it'll require less memory. Also make sure that no processes run that you don't need, i.e. kill cron, usbd, sendmail, ntpd and whatever else you don't absolutely need. I don't know if those measures will enable you to compile the kernel with 32 Mbytes, but it's worth a try. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co.
