Hi,

I just wanted to test logog. Created a win32 consolApp in vs2010.
Added the includes in Include, and libs in liibraries.

Called

logog::LogFile("D:\Testlog.log");

I get this error.

Error 1 error LNK2019: unresolved external symbol "public: virtual
__thiscall logog::LogFile::~LogFile(void)" (??1LogFile@logog@@UAE@XZ)
referenced in function _wmain D:\CVSSource\me_apm_components\apminsight
\source\dotnetagent\Solutions\TestLogog\TestLogog.obj TestLogog

What settings have I missed?

Hi jasper,

Not sure, but it might be related to the fact that LogFile and LogBuffer objects don't have virtual destructors.  I just fixed this; please get the latest code and try again.

Additionally, please use cmake when creating your project as per the getting started docs.

I just built it Release-x64. 

Made a test console app -> Release 64 -> included the libs and includes 

put this code in main 

LOGOG_INITIALIZE();

logog::LogFile errFile("log.txt");

INFO("Sample");

LOGOG_SHUTDOWN();

I got crash in node.cpp

From http://johnwbyrd.github.com/logog/quickstart.html:

"At this point, your Target object (in this case, the errOutput object) should be destroyed. Falling out of scope is the easiest way to achieve this."

Try

LOGOG_INITIALIZE();
{
logog::LogFile errFile("log.txt");
INFO("Sample");
}
LOGOG_SHUTDOWN();

It works perfect.

I have some questions

1. What if I want to adapt logog to for my logger. (Adaptor pattern). The "falling out of scope" will hold good? I did test this below sample and it worked without a problem. Still, I am skeptical about a crash, hence this question.

2. In the below code INFO(sMsg) gives error,  no suitable conversion function from "CString" to "const LOGOG_CHAR *" exists.

how to rectify this? CString is not supported, yes. But how to rectify it or what are the other options I can follow...? my logging can be in any language hence unicode is a must for me. Thats is why I use CString. (later on I will use string tables). 

class Logger

{

  Logger(){

  LOGOG_INITIALZE();

  logog::LogFile errFile(".Native.log");

 }

~Logger(){

  LOGOG_SHUTDOWN();

 }

 

void Info(CString& sMsg)

{

   INFO(sMsg);

1. The falling out of scope business was documented in the getting
started section.

http://johnwbyrd.github.com/logog/quickstart.html

2. You should read the documentation on Unicode that comes with logog.
