#247 'Unresolved External' in thread_test with VC7

[Anonymous]

Hi,

I just downloaded and compiled log4cplus using the
latest version of MS VC NET (7). To do this I loaded
the msvc6/log4cplus.dsw project (which was converted),
and told it to build. Everything compiles file and
most links fine too. Just the thread_test fails to
link, with the following error messages:

thread_test error LNK2019: unresolved external symbol
"__declspec(dllimport) public: __thiscall
log4cplus::helpers::SharedObjectPtr<class
TestThread>::~SharedObjectPtr<class TestThread>(void)"

I have tried defining _WIN32, and suchlike, but to no
avail.

I'm stuck. I would like this to work, so I would
appreciate any tips that might help.

Thanks,

Adam Crowther.

Go to pointer.h and find the line:
"class LOG4CPLUS_EXPORT SharedObjectPtr {"
and remove the LOG4CPLUS_EXPORT macro.
Template-Classes cannot be exported in VC7!

Did anyone resolve this? I currently have the same problem.

I too was having a linking problem with
log4cplus::helpers::SharedObjectPtr

Thanks for the help!

There was a problem and it has been fixed in the 1.0.3.
