I have updated sources as of Oct 25 and I tried building world (7.0-BETA1 AMD64), but I keep receiving the same error (see below) and I'm not sure how to fix it. I tried removing my sources completely and getting a fresh copy as well as running make clean in /usr/src, but to no avail. Anyone have any ideas? echo libc.so.7: /usr/obj/usr/src/lib32/usr/lib32/libgcc.a >> .depend /usr/local/libexec/ccache/world-cc -O2 -fno-strict-aliasing -pipe -O2 -fno-strict-aliasing -pipe -s -mtune=nocona -I/usr/src/lib/libc/include -I/usr/src/lib/libc/../../include -I/usr/src/lib/libc/i386 -D__DBINTERFACE_PRIVATE -I/usr/src/lib/libc/../../contrib/gdtoa -DINET6 -I/usr/obj/lib32/usr/src/lib/libc -I/usr/src/lib/libc/resolv -DPOSIX_MISTAKE -I/usr/src/lib/libc/locale -DBROKEN_DES -DPORTMAP -DDES_BUILTIN -I/usr/src/lib/libc/rpc -DYP -DNS_CACHING -DSYMBOL_VERSIONING -Wsystem-headers -Wall -Wno-format-y2k -Wno-uninitialized -Wno-pointer-sign -c fork.S /usr/local/libexec/ccache/world-cc -fpic -DPIC -O2 -fno-strict-aliasing -pipe -O2 -fno-strict-aliasing -pipe -s -mtune=nocona -I/usr/src/lib/libc/include -I/usr/src/lib/libc/../../include -I/usr/src/lib/libc/i386 -D__DBINTERFACE_PRIVATE -I/usr/src/lib/libc/../../contrib/gdtoa -DINET6 -I/usr/obj/lib32/usr/src/lib/libc -I/usr/src/lib/libc/resolv -DPOSIX_MISTAKE -I/usr/src/lib/libc/locale -DBROKEN_DES -DPORTMAP -DDES_BUILTIN -I/usr/src/lib/libc/rpc -DYP -DNS_CACHING -DSYMBOL_VERSIONING -Wsystem-headers -Wall -Wno-format-y2k -Wno-uninitialized -Wno-pointer-sign -c fork.S -o fork.So /usr/local/libexec/ccache/world-cc -O2 -fno-strict-aliasing -pipe -O2 -fno-strict-aliasing -pipe -s -mtune=nocona -I/usr/src/lib/libc/include -I/usr/src/lib/libc/../../include -I/usr/src/lib/libc/i386 -D__DBINTERFACE_PRIVATE -I/usr/src/lib/libc/../../contrib/gdtoa -DINET6 -I/usr/obj/lib32/usr/src/lib/libc -I/usr/src/lib/libc/resolv -DPOSIX_MISTAKE -I/usr/src/lib/libc/locale -DBROKEN_DES -DPORTMAP -DDES_BUILTIN -I/usr/src/lib/libc/rpc -DYP -DNS_CACHING -DSYMBOL_VERSIONING -Wsystem-headers -Wall -Wno-format-y2k -Wno-uninitialized -Wno-pointer-sign -c read.S fork.S: Assembler messages: fork.S:2: Error: invalid character '_' in mnemonic *** Error code 1 fork.S: Assembler messages: fork.S:2: Error: invalid character '_' in mnemonic *** Error code 1 read.S: Assembler messages: read.S:2: Error: invalid character '_' in mnemonic *** Error code 1 3 errors *** Error code 2 2 errors *** Error code 2 1 error *** Error code 2 1 error *** Error code 2 1 error Thanks.
