Zeos for Lazarus is officially ported! lazarus / 16-Databases ---------------------------------------------------------------------- Stevie · 2005-05-03 17:32 Hi everyone, the port to lazarus is done - fpc now has full support for variants and interfaces. Because the port is not "much more" than "a few" compiler directives, therefore the functionality is the same as it is on delphi or kylix. The sources you can get from the cvs on http://sourceforge.net/projects/zeoslib/ Regards, Stevie ---------------------------------------------------------------------- Anonymous · 2005-05-04 07:38 Could you give a little bit detailed download and build instructions ? ---------------------------------------------------------------------- Vincent Snijders · 2005-05-04 08:34 Stevie, may I suggest you create a zip with the needed sources and lazarus package? I think it would be great to have this component on Lazarus Code and Components page and available for download at the Lazarus CCR Files page. ---------------------------------------------------------------------- hombergs · 2005-05-04 08:58 @ Stevie: I reported a Patch for FPC/Lazarus under linux. Cause there are some functions missing. And I reported a bug. Cause under Linux the Firebird and SQLite driver will raise a range check error when you set the Connected propertie of the TZConnection to true. This will only happen when yyou set the propertie in  the IDE to true for testing. @Guest: You need a CVS client for getting this great piece of software. If you use Windows then try TortoiseCVS. The CVS server is: cvs.sourceforge.net Username: anonymous Repository Path: /cvsroot/zeoslib No password. Checkout the zeosdbo_rework (this is the actual Zeos). After checking out install the components in the following order: zcore.lpk zparsesql.lpk zplain.lpk zdbc.lpk zcomponent.lpk ---------------------------------------------------------------------- Vincent Snijders · 2005-05-04 09:07 I did some browsing through the cvs and have some questions/suggestions/remarks. The zcomponent package has a absolute path to the include files: If I understand the lazarus pacakge system correctly, the zcore, zparsesql, zplain and the zdbc package can be a runtime package only, because they don't install any components. Of course other packages can use it, and it still will be included in the lazarus executable. ---------------------------------------------------------------------- Stevie · 2005-05-04 12:49 @hombergs: I must confess that I only tested the windows version of Lazarus but this was only the first step. I try to setup a linux- system for testing and look for it, thanks! @vincent: Yes, you are right, but in the past the delphi-packages of zeos had to be installed too (I changed this already) I still am not very familiar with Lazarus but a few weeks ago I was not able to install only the component package without the others (maybe this behaviour changed? I will test this) ---------------------------------------------------------------------- Anonymous · 2005-05-04 14:38 Thank you, I will try it. The "zeosdbo_rework" was the missing info. I tired checkout zeosdbo, but all files seems very old. The rework seems far better :-) ---------------------------------------------------------------------- hombergs · 2005-05-04 15:09 @Stevie: I found the bug. FPC/Lazarus defines HMODULE as longint. But the dlopen function from libc returns sometimes a negative value. So I redifine HMODULE in ZCompatibility as longword now and it works. I uploaded a new patchfile. This include the changes that Vincent has suggested. ---------------------------------------------------------------------- Anonymous · 2005-05-04 15:46 I tired to compile it, but I've got the following error messages: Zeos.inc(42,2) Warning: Unsupported switch "$O" Zeos.inc(44,2) Warning: Unsupported switch "$W" Zeos.inc(42,2) Warning: Unsupported switch "$O" Zeos.inc(44,2) Warning: Unsupported switch "$W" Zeos.inc(42,2) Warning: Unsupported switch "$O" Zeos.inc(44,2) Warning: Unsupported switch "$W" Zeos.inc(42,2) Warning: Unsupported switch "$O" Zeos.inc(44,2) Warning: Unsupported switch "$W" /usr/lib/lazarus/zeos/src/plain/ZPlainLoader.pas(150,17) Error: Identifier not found "GetModuleHandle" /usr/lib/lazarus/zeos/src/plain/ZPlainLoader.pas(154,19) Error: Identifier not found "HMODULE" /usr/lib/lazarus/zeos/src/plain/ZPlainLoader.pas(181,5) Error: Identifier not found "FreeLibrary" /usr/lib/lazarus/zeos/src/plain/ZPlainLoader.pas(181,24) Error: Illegal expression /usr/lib/lazarus/zeos/src/plain/ZPlainLoader.pas(193,13) Error: Identifier not found "GetProcAddress" /usr/lib/lazarus/zeos/src/plain/ZPlainLoader.pas(199) Fatal: There were 5 errors compiling module, stopping The GetModuleHandle, etc seems WIN32 functions, I tired to compile it under linux (with the latest fpc binary snapshot). ---------------------------------------------------------------------- hombergs · 2005-05-04 16:17 Please apply the patch from the zeos patch tracker.

I just downloaded the latest CVS. Three questions: 1. I am trying to set a master-detail relation between two queries by using a Param in the SQL statement of the detail query. In Delphi this works but in Lazarus the detail query is empty. How can I solve this (I'd rather not use the 'Mastersource' option)? 2. Is there a problem with the Date type because all the years are displayed as 1899? 3. Is there ever going to be a Field Editor (like in Delphi)? Thanks, Edwin ---------------------------------------------------------------------- Anonymous · 2005-05-24 19:41 Hi, I've got a problem with using zeoslib with sqlite and mysql. Storing data works just fine, but to retrieve information from the database I have to use a construction with "ZQuery1.Open" which produces an exception regardless in what situation. The error code returned by the debugger is: "Project project1 raises exception class EZSQLException." Thanks in advance ---------------------------------------------------------------------- janhsh · 2005-05-25 22:38 I've got a problem with installing  zeoslib in zcompatiblity.pas  on line 170   LText := PChar(S); --> error "Illegal type conversion Shortstring to ^Char" Thanks in advance ---------------------------------------------------------------------- Stevie · 2005-05-27 07:08 Did you check out the lazarus-versions of packages also?

Best regards Romek ---------------------------------------------------------------------- Anonymous · 2005-06-07 15:19 Why is the master-detail relation through the Datasource property (so with a :Param in the SQL) of ZQuery not working? Thanks, Edwin ---------------------------------------------------------------------- Stevie · 2005-06-09 11:18 @romekf: This should be implemented by lazarus i.e. the lcl. @Guest: I think, this is also a problem with missing implementation within the lcl (db.pas) ---------------------------------------------------------------------- Edwin · 2005-06-09 15:07 @Stevie: Thanks for your reply. I don't think it is a problem within the lcl, because using UIB (with TFBDataset) it is working! Another thing: what is wrong with the Date field (everything is 30/12/1899)? By the way, I'm using Firebird 1.5.

Thanks, Edwin TField doesn't have a Editmask property yet, so the dbgrid implements an event that is called for each field OnFieldEditMask, however it is disabled because TCustomMaskEdit behaves different in windows and linux when using the editmask property. To enable the feature, recompile both grids.pas and dbgrids.pas with OPT="-dEnableFieldEditMask" option it will probably work ok in windows but expect problems in linux. ---------------------------------------------------------------------- Anonymous · 2005-07-29 17:14 I cant download zeosdbo_rework .
