Hello, A new question has been asked in "Client libraries" by olivierf77: -------------------------------- Hello, I have installed MariaDB 5.6 , and its works perfectly. Thanks to all the MariaDB team. I also installed (by *.msi) mariaDB_client-1-0-0_win64 in c:\L\SQLClient\mariadb_client-1.0.0-win64\ + added paths as follow in project properties: INCLUDE DIRECTORIES = C:\L\SQLClient\mariadb_client-1.0.0-win64\mariadbclient\include;$(IncludePath) LIBRARY DIRECTORIES = C:\L\SQLClient\mariadb_client-1.0.0-win64\lib;$(LibraryPath) However, when trying to use it even with the most simple programs, compilation is OK, **BUT** linking fails: --- my minimal c++ program (c++ console under Visual Studio 2012 --- #include "stdafx.h" #include int _tmain(int argc, _TCHAR* argv[]) { MYSQL *my; my = mysql_init(NULL); } -- end of program -- BUILDING PROJETS -> following error msg: 1>------ Build started: Project: cppconMariaDB02, Configuration: Debug Win32 ------ 1>cppconMariaDB02.obj : error LNK2019: unresolved external symbol _mysql_init@4 referenced in function _wmain 1>c:\users\olivier\documents\visual studio 2012\Projects\cppconMariaDB02\Debug\cppconMariaDB02.exe : fatal error LNK1120: 1 unresolved externals ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== Every mysql function gets the same "unresolved external symbol" error, even though I believe I did specify the path to the directory containing the 3 files "libmariadb.dll, libmariadb.lib & mariadbclient.lib", which I even tried (for testing purposes only, and with no better results) to copy into windows/system32. I have spent a lot of time on this issue, with no success. I did see that this question was asked several times on several programming sites, but it never gets any answer. As additional info, here is my directory for the c mariadb_client client: Directory of c:\L\SQLClient\mariadb_client-1.0.0-win64 <DIR> .. docs examples html lib libmysql mariadbclient mysql_config unittest zlib I hope that the above information (and question) is clear and complete, but not over verbose, and that someone in your team will have a few seconds to answer my query, even though the answer may be trivial (at least for him). And once again, many thanks for a very nice product. Sincerely yours Olivier, Paris, France PS And hello to Michael 'Monty' Widenus, whom I met in Paris six months ago. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/mariadb_client-1-0-0_win64-in-visual-studio-2012/
