[fpc-devel]gdb issue
Hi, i tried to view integer variable value in binary mode using gdb (5.2.1, windows, fpc1010 ) command "p /t i". But it shows nothing. Does anyone else come across this issue or i am doing something wrong?

[fpc-devel]Fixes for interbase/db
Hi all,
i have some fixes for the database implementation in FCL.
Changes in interbase.pp:
* Removed unused Fprepared
* Changed the error message 'database connect string not filled
in' to 'database connect string (databasename) not filled in'
* Preparestatement and execute now checks if transaction is
assigned (in stead of crashing if it isn't) and if the
transaction isn't started, it calls starttransaction.
Changes in dataset.inc:
* In DoInternalOpen the buffers are now initialised before the
dataset is set into browse-state
Changes in database.inc and db.pp:
* If the dataset is created from a stream, the database is opened
after the dataset is read completely

It does, but they don't overwrite the units installed by your release (not under *nix anyway, I don't know about the win32 version). As such, the new compiler is probably still trying to use old units. Jonas ___ fpc-devel maillist - [EMAIL PROTECTED] http://lists.freepascal.org/mailman/listinfo/fpc-devel
Re: [fpc-devel]Fixes for interbase/db
i have some fixes for the database implementation in FCL.
Ok, since my development-machine had no internet-connection i've made
the patch files myself, but the database.diff wasn't correct. Here are
the right ones.

[fpc-devel]CVS Broken?

[fpc-devel]MySQL component installation
I have been trying to install the MySQLLaz package into my Lazarus system. It compiles OK, but on linking I get the following errors: ...undefined reference to `mysql_connect' ...undefined reference to `mysql_create_db' ...undefined reference to `mysql_drop_db' error while linking This is because I have MySQL v4 installed in my Linux distro (SuSE 9.0 or 9.1) and also WinXP, and the library no longer recognises these calls. I pointed out in my tutorial on the WiKi http://lazarus-ccr.sourceforge.net/index.php?wiki=LazarusDatabase that changes had to be made to the fpc mysql unit (I used a re-named unit mysql_ver4) when creating simple applications to access late versions of MySQL. Although there are files for access to ver 3.3.2 and ver 4 in subdirectories of ($sourcepath)/fcl/packages/base/mysql, the units in component packages that use mysql have no mechanism to distinguish between the different versions. There is a file in each of the directories called mysql_version, but it only defines the version as a string, and doesn't do anything to modify the function calls. In Version 4 of MySQL the function mysql_connect has been replaced by mysql_real_connect (now with 8 parameters instead of 4); mysql_create_db and mysql_drop_db have been deprecated in favour of issuing explicit SQL statements to perform the same function. I think the mysqldb unit needs to have some conditionals (to take account of MySQL versions) inserted into the section of the implementation dealing with these functions (unless I am missing something that is already there?). I am prepared to have a go at making the necessary modifications, but am reluctant to do so if there is already some mechanism in place to cope with changes in version of MySQL, or if one of the original developers can do it better and faster. We need to be able to define the version of MySQL - usually this is only done at link time by selecting the appropriate library. We are probably going to have to ask the user what version he's using before we compile. Can I have some guidance please from the FPC developers?
