Failing build from subversion repository
by Keith Dart 13 Dec '05

13 Dec '05

I obtained a subversion copy of libsmi, and try to build it (on two machines), I get the following: gcc -DHAVE_CONFIG_H -I. -I. -I.. -g -O2 -MT parser-smi.lo -MD -MP -MF .deps/parser-smi.Tpo -c parser-smi.c -o parser-smi.o >/dev/null 2>&1 make[2]: *** No rule to make target `parser-smi.tab.h', needed by `scanner-smi.c'. Stop. make[2]: Leaving directory `/u01/home/kdart/src/libsmi/trunk/lib' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/u01/home/kdart/src/libsmi/trunk' make: *** [all] Error 2 But I have flex and bison: 403 !$ bison --version bison (GNU Bison) 1.875 404 $ flex --version flex version 2.5.4 It looks like the Makefile does not include a rule for this, after all. -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Keith Dart <kdart(a)kdart.com> public key: ID: F3D288E4 =====================================================================

Libsmi 0.4.3 memory fault (Linux/gcc)
by Allen McIntosh 03 May '05

03 May '05

The libsmi parser memory faults when parsing mibs/ietf/DOT12-RPTR-MIB. Repeat by running smilint mibs/ietf/DOT12-RPTR-MIB after installing libsmi. This happened to me under RedHat 9 (gcc 3.2.2/x86) and RedHat 7.3 (gcc 2.96/x86). The parser usually runs off the rails thus: $ gdb /usr/local/bin/smilint [stuff omitted] (gdb) run mibs/ietf/DOT12-RPTR-MIB Starting program: /usr/local/bin/smilint mibs/ietf/DOT12-RPTR-MIB mibs/ietf/DOT12-RPTR-MIB:36: revision for last update is missing mibs/ietf/DOT12-RPTR-MIB:151: warning: use Integer32 instead of INTEGER in SMIv2 Program received signal SIGSEGV, Segmentation fault. 0x40037b15 in checkObjects (parserPtr=0xbffff5f0, modulePtr=0x80559a0) at parser-smi.y:220 220 if (objectPtr->nodePtr->parentPtr && (gdb) where #0 0x40037b15 in checkObjects (parserPtr=0xbffff5f0, modulePtr=0x80559a0) at parser-smi.y:220 #1 0x4003a26c in smiparse (parserPtr=0xbffff5f0) at parser-smi.y:1641 #2 0x40031021 in loadModule ( modulename=0xbffff841 "mibs/ietf/DOT12-RPTR-MIB", parserPtr=0x0) at data.c:3792 #3 0x40035110 in smiLoadModule (module=0xbffff841 "mibs/ietf/DOT12-RPTR-MIB") at smi.c:416 #4 0x080492f2 in main (argc=2, argv=0xbffff6f4) at smilint.c:314 #5 0x42017589 in __libc_start_main () from /lib/i686/libc.so.6 (gdb) print objectPtr->nodePtr->parentPtr $1 = (struct Node *) 0x62696d2f Running with ElectricFence and EF_PROTECT_BELOW on turns up a problem, if that helps. I can provide details if that would help.

Does not smiInit() read config ?
by KUBOTA Takaya 08 Mar '05

08 Mar '05

Hi all, I'm a newbe and using libsmi for parsing COPS PIB files. I have a question about smiInit(). manual smi_config(3) says: The smiInit() function should be the first SMI function called in an application. It initializes its internal structures. If tag is not NULL, the global configuration file and (on UNIX systems) a user configuration file are read implicitly, if existent. All global statements and those statements with a tag (a ``tag: '' prefix) that matches the tag argument are executed. (see also CONFIGUュ RATION FILES below). smiInit() returns zero on success, or otherwise a negative value. However, source code smi.c (smiInit()) dose not seem to read a global configuration file when tag is NULL. Should I call smiReadConfig() by myself or did I some mistakes ? Thanks in advance for your time. regards -- KUBOTA,Takaya@NTT SOFTAWARE CORPORATION <takaya(a)po.ntts.co.jp>
