Error installing zeos components lazarus / 16-Databases ---------------------------------------------------------------------- gelinp · 2015-11-02 18:09 Hi, Installing zeos zcomponent v7.2 component,  I've got the error message (in french) : ZDbcAdo.pas(136,21) Fatal: Impossible de trouver l'unité ZDbcAdoMetaData utilisé par ZDbcAdo du paquet zdbc. I don't understand because Lazarus show me zdpc component is already installed... May be Lazarus need to recompile and link one more time. Also zdbc compile withour any problem, but I can't desinstall it because of the same problem... So what is the problem and where do I find ZDbcAdoMetaData unit ? My configuration is Linux Debian Jessie, and Lazarus 1.4.4 with FPC 2.6.4 Thank you for your help ! ---------------------------------------------------------------------- miab3 · 2015-11-02 19:17 ADO is possible only in the Windows 32/64. In Linux to connect by ZEOS to MSSQL, you can use freetds. Michal ---------------------------------------------------------------------- gelinp · 2015-11-03 06:04 Finaly Zeos run under linux. But I had to compil starting lazarus with kdesudo, because of lazarus installation under /usr/... root only directory. ---------------------------------------------------------------------- mangakissa · 2015-11-04 07:58 Why install in this directory? Are there more people who works with the same linux server. ---------------------------------------------------------------------- gelinp · 2015-11-04 13:51 I don't remember how I installed lazarus, may be it was a debian package and I couldn't choose the location... I suppose I din't choose this repository, because I Install often tiers applications into /opt directory. ---------------------------------------------------------------------- gelinp · 2015-11-11 08:14 What is ADO exactly ? A framework used by zeos to connect databases ? Do I need to install a specific ADO package in order to compil zeos for windows target (there is no ADO files into zeos/lib directory) ? What to do if would like to use freetds ? For Freetds I can read into readme file into zeos/lib directory : Code: Pascal  [Select][+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i All Lazarus controls assume all strings are UTF8Encoded which the MsSQL Servers do not understand.So we need a compiled FreeTDS version with libiconv2.dllDownloadlink: ftp://ftp.freepascal.org/fpc/contrib/windows/Use TZConnection.LibraryLocation := 'dblib.dll'; to load the right library.Actually we are looking for somebody who can compile the FreeTDS lib with the StoredProc functions. Actually we do NOT support Strored procedures/functions with the FreeTDS library. So, it looks like freetds is not delivered with zeos...
