You can do that on your own system, but it's not a solution for
distributing your application (/usr/lib is off-limits to third
parties, and while you could use /usr/local instead it's just hackish).
The main problem to me seems that the database units are all very
rigid regarding how the database library should be found. There
appears to be no way at all to say where the library is or may be
located. And there also appears to be no way either to link to the
Firebird client libaries directly (e.g. by adding {$linkframework
Firebird} to your main program and embedding the framework in your
application bundle -- well, you can do that, but the firebird units
still won't work because they insist on having the library available
under a particular name and findable using dlopen).

This is not correct:
function InitialiseIBase60(Const LibraryName : String) : integer;
You can specify the full path if you want.

This is also not correct, there is a ibase60 unit which - contrary to the
ibase60dyn unit - is statically linked.
TSQLQuery and friends use the dynamically loaded version, for good reason:
they must be usable in circumstances where you don't know if the library is
present or not, as is the case in Lazarus, the database desktop and whatnot.

All you'd need to do is include the unit, I suppose. The dlopen() should
then probably return the already linked library ?

Re: [fpc-pascal] Changes in sockets unit

All the code was already deprecated since 2.0, but the "deprecate" function was only new in 2.2.0, and 2.2.0 had to be 2.0.4 compilable. Use the fp* versions of the functions as much as possible. They have standard errorhandling like documented by e.g. manpages. The older functions had their own conventions related to 1.0.x Linux unit behaviour, which is why they were deprecated. Since they don't hurt that bad it was decided to not remove them directly, but have a reasonable grace period. However 2.0.0 is now almost 4 years ago, and in 2.4 they will be removed. > Why are Sock2Text and Text2Sock deprecated? You know, they're very handy > (sometimes).

Thanks in advance!
[Any ideas why this works:
ExecuteName := (AppPathExe + 'Del2Pas.bat.lnk');
ExecuteShell; ]
[But this doesn't work:
ExecuteName := (AppPathExe + 'Del2Pas.bat');
ExecuteShell;
And doesn't give an error msg.]
Just trying an educated guess here, but I suppose .bat-files can only be
executed via command.com (cmd.exe). Something like "%COMSPEC% /c
Del2Pas.bat" could do the trick.
