Hello lists, I download the newest squid version of "squid-2.6.STABLE6" and try to compile it with arguments below: ./configure --prefix=/home/squid --enable-async-io=32 --enable-removal-policies=heap,lru --with-maxfd=65535 --enable-epoll --with-large-files --enable-snmp --disable-cache-digests --disable-poll --disable-ident-lookup --disable-wccp --disable-select --enable-dlmalloc --enable-referer-log But the 'configure' command can't get continued,it reported the errors below and exit. checking for void *... yes checking size of void *... configure: error: cannot compute sizeof (void *), 77 See `config.log' for more details. My OS is Linux kernel 2.6.19. Please help,thanks.
