RE: [libsmi] import problem

Standard MIB SNMPv2-CONF has a import clause: IMPORTS ObjectName, NotificationName, ObjectSyntax FROM SNMPv2-SMI; and then during ObjectSyntax is imported, there is an error (CheckImport function returns a value 1), because cannot import ObjectSyntax and I don't know why. Maybe this is unimportant. Please, short answer. Regards Tom Styczynski

import problem
by miksiu 20 Dec '04

20 Dec '04

Hi all! During working with libsmi library (0.4.1) I detect some problems. There is a CheckImport() function in data.c file, which returns a integer value. This value is equal to number of not imported items. This function is using in parser-smi.y file. I add some code and functions to libsmi to control this returned value and it works ok (my code return names of items which can't be imported or names of not existing modules). It allowed me to detect import error during importing ObjectSyntax item from SNMPv2-SMI module. I don't know why this error appears. I need some sugestions how can I repair this error. When I use oryginal code of 0.4.1 library and when in my lib file is : IMPORTS ObjectSyntax FROM SNMPv2-SMI the "n" variable in CheckImport() function equals 1, but normally there is no checking this returned value in parser-smi.y file. Please help me. Regards Tom Styczynski

libsmi to C++
by Apostolos Manolitzas 14 Dec '04

14 Dec '04

Hello, reading through the library I discovered that it can genarate java and c modules from the MIB. Is it possible to generate c++ objects from a PIB? Has anyone achieved that? thanks for your time, Apostolos -- Apostolos Manolitzas | amanol(a)nospam.iit.demokritos.gr NCSR Demokritos | Telecommunications Engineer mob: +30 6972 172547 | tel: +30 210650 3000 ext.3167 pgp key at: http://www.ist-athena.org/~amanol/pgp.asc

Python interface
by Keith Dart 02 Dec '04

02 Dec '04

In case anyone is interested I now have complete Python wrapper/interface for the libsmi. Well, the user/programmer interface is actually very different, but it does use the libsmi underneath. Let me know if you are interesting in it. It is part of my pyNMS package and you can download it from sourceforge. http://www.sourceforge.net/projects/pynms -- \/ \/ (O O) -- --------------------oOOo~(_)~oOOo---------------------------------------- Keith Dart <kdart(a)kdart.com> vcard: <http://www.kdart.com/~kdart/kdart.vcf> public key: ID: F3D288E4 URL: <http://www.kdart.com/~kdart/public.key> ============================================================================

Re: smilint remembers named number in OID value assignment

Thanks to all who contributed to this issue. I've just comitted a new revision to the libsmi SVN repository that handles OID and identifiers in the "NameAndNumberForm" more acurately, and also emits warnings such as... ./XXX-MIB:165: warning: object identifier for label `snmpDot3MauMgt' does not match previous label usage ./XXX-MIB:40: info: previous definition of `snmpDot3MauMgt' ./XXX-MIB:165: warning: label `snmpDot3MauMgtXXX' does not match previous label `snmpDot3MauMgt' for same object identifier ./XXX-MIB:40: info: previous definition of `snmpDot3MauMgt'

parser compilation problem
by miksiu 29 Nov '04

29 Nov '04

Hello! I'm working with libsmi-0.4.1 and I have one problem. I don't know what options was used to compile parser-smi.y file. I compiled this file with command (I didn't make any changes in this file): bison -d parser-smi.y and after this I have two files: parser-smi.tab.c 294KB parser-smi.tab.h 7KB Size of these files is different than size of original files in libsmi-0.4.1 (in turn: 292KB and 1KB). In addition when I try to compile whole libsmi library with original parser files, everything is allright, but with these files which I got as a result of bison's work I have error: NMAKE : fatal error U1077: 'cl' : return code '0x2' To compile library I use makefile file from win directory as it is shown in README.win file. Maybe the original files were compiled with other options or I do some mistakes during compilation parser-smi.y file. Help me, please! Tom

using libsmi
by miksiu 22 Nov '04

22 Nov '04

Hi all!! My name is Tom and i'm from Poland. I'm new at this lists. I have one question about libsmi. When I compile and install the library into for example: C:/smilib-0.4.1 I have to files in C:\smilib-0.4.1\ : libsmi.a 798kB libsmi.la 1kB What should I do now in my main program. I wrote (Visual C++ 6.0): #pragma comment(lib, "C:\\smilib-0.4.1\\lib\\libsmi.a") but it doesn't work and there are linker errors for example: libsmi.a(data.o) : error LNK2001: unresolved external symbol __imp___ctype_ Other older versions of my program used other lib files. In the install library directory were two files after installing: smiDEBUG.lib 775kB smi_MT.lib 566kB and it works without problems. Please for any requests as soon as possible!!! Regards!!! Tom

libsmi-svn related changes (generic and win related)
by Erik Nase 06 Oct '04

06 Oct '04

Hi, appended is a diff against the latest svn repository about some common and some win related issues: common stuff: * lib/smi.c: changed smiAsprintf() calls to format SMI_LANGUAGE_UNKNOWN as decimal value. comment: SMI_LANGUAGE_UNKNOWN is defined as 0 in lib/smi.h.in, so putting it as a format-string parameter to smiAsprintf() will fail. but i guess, replacing ``smiAsprintf(&s, SMI_LANGUAGE_UNKNOWN)'' by ``smiAsprintf(&s, "%s", "<language unknown>")'' would be more helpful. * tools/dump-cm.c: explicit casting of double precision calculation to float. comment: something like ``(float) val / 2.0'' results in a double value, because the float cast only belongs to val. so a ``(float) (val / 2.0)'' is better; but in ages of processor integrated math-units using double values should be no problem anyway. * tools/dump-sizes.c: win-platform support and int64 abs calculation fix. comment: the abs(3) function from stdlib.h takes and returns a integer, leading to possible precision loss with int64 values. at least linux has a llabs() call, but at least vc6 does not support it, so introducing this local m_abs() macro should be a good way to go. * tools/dump-svg.c: unused variable cleanup comment: this just cosmetic. * tools/dump-xsd.c: win-platform support and use of predefined UINT64_MAX values instead of local hardcoded constants. constants: likewise used in other modules this is for portability, especially windows, only. and these explicitly win related changes: * win/makefile: add dump-svg module. * win/win.h: include limits.h for 64bit limits. * win/Makefile.mingw: add dump-svg module and make linux cross-compile the default setting well, at least the smiAsprintf() change in lib/smi.c and the m_abs() macro in tools/dump-sizes.c seems to be a real bugfix and should be worth to be included. have fun, Erik ---------------------------------------------------------------------- diff -d -u -r libsmi-svn-2004-10-05-orig/lib/smi.c libsmi-svn-2004-10-05/lib/smi.c --- libsmi-svn-2004-10-05-orig/lib/smi.c Tue Oct 5 14:44:57 2004 +++ libsmi-svn-2004-10-05/lib/smi.c Tue Oct 5 22:49:06 2004 @@ -1768,7 +1768,7 @@ if (!
