Hi All,
I trying the mysql connector (v 1.1.0, included with the mysql installer I used on my machine), and I am having a hell of a time with it.
I am trying to follow the example here: http://blog.ulf-wendel.de/?p=215#hello
No matter what I do, I get LNK:2001 Unresolve external symbol get_driver_instance()
Here's what I have and have done:
I am using Visual Studio 2008 on Windows 7 X64
I have configured my project initally exactly as described in the blog twice, once statically and once dynamically linking. Both times I get the same unresolved external
I have installed the boost libraries as directed in another forum post, and they are being referenced properly
I have tried defining mysqlcppconn_EXPORTS as mentioned at one point for static linking, which did not work, and for good measure, I also tried this for the dynamic link, which did not work either (as I expected it wouldn't, but I wanted to be thorough) this was also tried with CPPCONN_PUBLIC_FUNC= defined and not defined (for both builds in both debug and release) same result
I have added the directories for the libraries to the linker settings under additional library directories, did not help.
I have tried both debug and release for both builds, same result.
I did try adding using namespace sql::mysql; as directed in another forum post
My compiler command line settings are:
/O2 /Oi /GL /I "C:\Program Files\MySQL\Connector C++ 1.1.0\include" /D "WIN32" /D "NDEBUG" /D "_CONSOLE" /D "mysqlcppconn_EXPORTS" /D "_UNICODE" /D "UNICODE" /FD /EHsc /MT /Gy /Yu"stdafx.h" /Fp"Release\mysql test.pch" /Fo"Release\\" /Fd"Release\vc90.pdb" /W3 /nologo /c /TP /errorReport:prompt
My linker command line settings are:
/OUT:"f:\mysql test\Release\mysql test.exe" /INCREMENTAL:NO /NOLOGO /MANIFEST /MANIFESTFILE:"Release\mysql test.exe.intermediate.manifest" /MANIFESTUAC:"level='asInvoker' uiAccess='false'" /SUBSYSTEM:CONSOLE /OPT:REF /OPT:ICF /LTCG /DYNAMICBASE /NXCOMPAT /MACHINE:X86 /ERRORREPORT:PROMPT kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib
I know I am either missing something or I do not have something set properly but I can't for the life of me figure out what.
