Basic context: # freebsd-version -ku; uname -apKU 11.0-CURRENT 11.0-CURRENT FreeBSD FBSDG5C0 11.0-CURRENT FreeBSD 11.0-CURRENT #1 r279514M: Sat Mar 21 05:15:23 PDT 2015 root_at_FBSDG5C0:/usr/obj/usr/srcC/sys/GENERIC64vtsc-NODEBUG powerpc powerpc64 1100062 1100062 The problem: Summary of the details that are listed later. Both of the following exist: /usr/src/sys/netinet/sctp.h /usr/include/netinet/sctp.h The first can be newer than the 2nd during buildworld. The buildworld compile of /head/lib/libc/net/sctp_sys_calls.c from an updated /usr/src can/does end up using the second instead of the first, at least for the powerpc64-xtoolchain-gcc style of buildworld activity that I am trying. The recent addition of SCTP_MAX_CWND ends up with its definition missing because of this: during the build /usr/include/netinet/sctp.h ends up being the file included and the compile fails from the missing additional definition. Either the #include paths in /head/lib/libc/net/sctp_sys_calls.c or the command line arguments should force the /usr/src/sys/netinet/sctp.h vintage file to be found. The 3 netinet/ relevant includes are shown below... > ... > #include <netinet/in.h> > #include <arpa/inet.h> > #include <netinet/sctp_uio.h> > #include <netinet/sctp.h> More than sctp.h might have such issues since there are 3 netinet/ include paths in /head/lib/libc/net/sctp_sys_calls.c . I have not checked for other .c files with similar issues for <netinet/...> usage during buildworld. The problem details: /head/lib/libc/net/sctp_sys_calls.c -r279859 added: > case SCTP_MAX_CWND: > ((struct sctp_assoc_value *)arg)->assoc_id = id; > break; and head (20150325 r280598) contains it. But the SCTP_MAX_CWND reference blocks buildworld (for at least /usr/local/bin/powerpc64-portbld-freebsd11.0-gcc (powerpc64-xtoolchain=gcc) use): > /usr/local/bin/powerpc64-portbld-freebsd11.0-gcc -fpic -DPIC -O2 -pipe -I/usr/src/lib/libc/include -I/usr/src/lib/libc/../../include -I/usr/src/lib/libc/powerpc64 -DNLS -D__DBINTERFACE_PRIVATE -I/usr/src/lib/libc/../../contrib/gdtoa -I/usr/src/lib/libc/../../contrib/libc-vis -DINET6 -I/usr/obj/usr/src/lib/libc -I/usr/src/lib/libc/resolv -D_ACL_PRIVATE -DPOSIX_MISTAKE -I/usr/src/lib/libc/../libmd -I/usr/src/lib/libc/../../contrib/jemalloc/include -DMALLOC_PRODUCTION -I/usr/src/lib/libc/../../contrib/tzcode/stdtime -I/usr/src/lib/libc/stdtime -I/usr/src/lib/libc/locale -DBROKEN_DES -DPORTMAP -DDES_BUILTIN -I/usr/src/lib/libc/rpc -DYP -DNS_CACHING -DSYMBOL_VERSIONING -DSYSCALL_COMPAT -std=gnu99 -fstack-protector -Wsystem-headers -Wall -Wno-format-y2k -Wno-uninitialized -Wno-pointer-sign -c /usr/src/lib/libc/net/sctp_sys_calls.c -o sctp_sys_calls.So > > /usr/src/lib/libc/net/sctp_sys_calls.c: In function 'sctp_opt_info': > /usr/src/lib/libc/net/sctp_sys_calls.c:386:7: error: 'SCTP_MAX_CWND' undeclared (first use in this function) > case SCTP_MAX_CWND: ^ Looking to see where usage and definitions might be in /usr/src for -r280598 ... > # pwd > /usr/src > $ find . \( -type d -name .svn -prune \) -or \( -type f -exec grep SCTP_MAX_CWND {} \; -print \) | more > case SCTP_MAX_CWND: > ./lib/libc/net/sctp_sys_calls.c > case SCTP_MAX_CWND: > case SCTP_MAX_CWND: > ./sys/netinet/sctp_usrreq.c > #define SCTP_MAX_CWND 0x00000032 > ./sys/netinet/sctp.h And looking at the list of includes in /head/lib/libc/net/sctp_sys_calls.c for -r279859 shows: > #include <sys/cdefs.h> > __FBSDID("$FreeBSD$"); > > #include <stdio.h> > #include <string.h> > #include <errno.h> > #include <stdlib.h> > #include <unistd.h> > #include <sys/types.h> > #include <sys/socket.h> > #include <sys/errno.h> > #include <sys/syscall.h> > #include <sys/uio.h> > #include <netinet/in.h> > #include <arpa/inet.h> > #include <netinet/sctp_uio.h> > #include <netinet/sctp.h> That there was no complaint about sctp.h being missing suggests that a <netinet/sctp.h> was found but did not contain a SCTP_MAX_CWND definition: so a different one than the above find/grep reported.
