Summary: log4cplus and lnk2001 errors

Initial Comment:
Hi,

I am trying to use log4cplus in a larger project. I need to use the static version of log4cplus under windows using visual studio 2008. I have already added the lib path, the lib itself and the include directory to my project. After adding the "#include" line in my source file I thought I would be able to use log4cplus, but that isn't the case. I am ending up with lnk2001 (__declspec) errors which say that even the ctors can't be found. I have been looking through the unicode options of my project as well - with no success. I also tried different versions of log4cplus ...

What am I doing wrong?

Hi,

I have tried log4cplusS.lib, log4cplusSD.lib and log4cplusUSD.lib.
I have also tried to set the lib and the project to unicode by using the
project properties in visual studio.
Still no success.

I also thought about mixing release and debug builds up - but that wasn't
the case.

Thank you for your reply.

Typically, problems like this are caused by mix of log4cplus compiled with

Summary: Buffer overrun with Hello World example

Initial Comment:
I'm attempting to use logforcplus in my first c++ project in over ten years, so please assume I might have done something simple wrong.  I cannot get the Hello World example working without buffer overrun errors.

I downloaded log4cplus-1.1.0-rc10. I used VS2010 to open the sln in msvc10 folder, set log4cplus project to Debug_Unicode, and compile.
I created a new project directory log4cplusDemo, with subdirectories bin, include, lib, and src.  "Bin" contains log4cplusUD.dll and pdb, "include" contains include\log4cplus, and "lib" contains log4cplusUD.lib.

I used VS2012 to create a new C++ Win32 exe in the "src" directory.  Project Properties..Configuration Properties..General..Character Set is Unicode.  Configuration Properties..C/C++..General..Additional Include Directories has a reference to "include".  Configuration Properties..Linker..General..Additional Library Directories has a reference to "lib". Linker..Input..Additional Dependencies has a reference to "log4cplusUD.lib".

Trying the hello world example resulted in a buffer overrun error. I was able to expand the macro and isolate the failing line.  Replacing it with a hardcoded string works, but causes a buffer overrun when main() exits.  What am I doing wrong?

#include "stdafx.h"

#include <log4cplus/logger.h>
#include <log4cplus/loggingmacros.h>
#include <log4cplus/configurator.h>

using namespace log4cplus;

int _tmain(int argc, _TCHAR* argv[])
{
    BasicConfigurator config;
    config.configure();
    
    Logger logger = Logger::getInstance(LOG4CPLUS_TEXT("main"));
    
	// This causes buffer overrun on this line
	// LOG4CPLUS_WARN(logger, LOG4CPLUS_TEXT("Hello, World!"));
	
	// This works (by commenting out original call to .str() and sending a string directly),
	// but buffer overflow error occurs on return statement.

            _log4cplus_buf << LOG4CPLUS_TEXT("Hello, World!");

AFAIK, you cannot do that. Trying to combine VS 2010 built library and VS
2012 compiled executable, in general, does not work. Build log4cplus using
VS 2012 as well. I have not tried but there should be no problem opening
the VS 2010 solution in VS 2012 and building it there.

Assuming that both logVar1 and logVar2 point to the same logger instance
(same logger name "foo.bar.baz"), then it is sufficient to change the
log level through just one of the two variables.

You do not have to use a property file to change log level for one or
two loggers. You can just call
logVar1->setLogLevel(log4cplus::OFF_LOG_LEVEL) and nothing will be
logged through logVar1 any more.

[Log4cplus-devel] FW: change level for different loggers

From: Tobias A. <tob...@ho...> - 2012-09-21 21:23:09






Hey im very new to log4cplus and woundering following:

logger logVar1;
logger logVar2;

if i have two different logger in my code and i want to change the level to be logged for only one off. I want to do this from the property file. how should i solve this? I have read examples on doing this for only one logger variable but not for 2 separeatly.
I want to change the levels during run time and therefore i have to use the property file. 

Thanks in advance!

Summary: Compilation of liblog4cplus 1.0.5 (HEAD) failed on Solaris 8

Initial Comment:
libtool: compile:  CC -DHAVE_CONFIG_H -DINSIDE_LOG4CPLUS -I../include -I../include -DNDEBUG -DUNICODE -D_REENTRANT -g +w -library=stlport4 -library=Crun -D_REENTRANT -c stringhelper.cxx  -KPIC -DPIC -o .libs/stringhelper.o
"stringhelper.cxx", line 360: Error: towupper is not a member of file level.
"stringhelper.cxx", line 378: Error: towlower is not a member of file level.

To build the library I have to launch ./configure CFLAGS=-DUNICODE CPPFLAGS=-DUNICODE
and include <wchar.h> for towupper and towlower functions in stringhelper.cxx.

Is it possible to make UNICODE an option as it is for REENTRANT (enable-threads) ?

Message:
As for the -DUNICODE, I have thought about it in the past and I have
decided not to do it. You might want to use single copy of headers with
separate binaries for both wchar_t and char versions of the library. The
REENTRANT define does not leak into the user space, its situation is
slightly different.

Hmm. I think that what needs changing are the bodies of toupper_func and
tolower_func, removing the inner #ifdef. I have committed the change in
revision 1521. Please try to compile it now.

Hi,
when i tried compile helloworld app there was error message:
error C2665: 'log4cplus::Logger::getInstance' : none of the 2 overloads could convert all the argument types

to fix this you have to replace 
    Logger logger = Logger::getInstance("main");
to
    Logger logger = Logger::getInstance(L"main");

The examples are very basic. You should use LOG4CPLUS_TEXT("main") instead

Summary: Using cmake is impossible on Linux withtout configure step

Initial Comment:
I just tried to use cmake to build the product on Linux and got errors (see below). After "./configure" command cmake works. The package does'nt contain  log4cplus/config/defines.hxx but only  log4cplus/config/defines.hxx.in. Thus configure step is mandatory now. Is it possible to fix that (cmake feature is cool)!

Summary: PatternLayout: printing just the file name

Initial Comment:
Right now, when using %F in a pattern, the filename as seen by the compiler gets used. This can include parts of a relative path, especially for headers (but also when an out-of-tree build was used while compiling the source). This looks ugly.

I have two suggestions:
- Change %F (and %l) to just print the substring after the last directory seperator ("/" or "\", depending on OS).
- Add new modifiers that do the above.

Please let me know if you see this as an issue that should be fixed and which fix you would prefer.

Thanks,
Uli

This is already implemented using %b specifier at least on trunk. .
