[fpc-pascal] linking to dll still fails
Hi,
I still have no success in linking against a dll on windows.
The dll import source looks like this:
...
{$linklib 'hdf5'}
...
function H5open:herr_t;{$ifdef BSD}cdecl{$endif}{$ifdef
Win32}stdcall{$endif};external;
function H5close:herr_t;{$ifdef BSD}cdecl{$endif}{$ifdef
Win32}stdcall{$endif};external;
...
and compiles okay.
The demo program used for testing does the obvious:
...
uses {$ifdef FreeBSD} BaseUnix { size_t an friends }, {$endif}
hdf5;
...
and uses functions normally as declared in the unit hdf5.
On FreeBSD this works as expected, on window it doesn't. Using -vv gave
(shortened, can be posted in full lenght):

...
I have only adjusted some basic functions to use stdcall instead of
cdecl on windows, so ignore the lines about undefined symbols having an
underscore at the start.
The dll is in the program directory. And it does get found. Another
issue might be:
in the units target dir there are three files:
-rw-rw-rw- 1 user group 77104 Jun 7 05:45 hdf5.o
-rw-rw-rw- 1 user group 154410 Jun 7 05:45 hdf5.ppu
-rw-rw-rw- 1 user group 8 Jun 7 05:45 libimphdf5.a
If I assume the libimphdf5.a is the missing import library and look at
it:
!
That's in there, nothing else (8 bytes).
What's going wrong here, how can I make it work?
TIA,
Marc

[fpc-pascal] code speed and size on various platforms
I would like to create a shot overview of the code quality of FPC. Please help to complete the list: Under i386 code size and speed is similar to Delphi and gcc (except for some synthetic benchmarks). Under x86_64 pentium code size and speed is similar to gcc (exc...). Under x86_64 amd code size and speed is similar to D and not that far away from gcc (exc...). Under arm code size and speed is similar to ? (exc...). Under powerpc code size and speed is similar to ? (exc...). Under sparc code size and speed is similar to ? (exc...).

Have a look at the documentation for formatdatetime and the comments in the

ScanDateTime('?MM?dd?hh?nn?ss',str); // seems to work fine here.

Re: [fpc-pascal] Date conversion question
I would say the easiest would be to extract the different parts: Year, Month, Day, Hour, Min, Sec and then use EncodeDateTime() to return a TDateTime type. I have implemented (with unit tests) the last format (ISO 8601) in the tiOPF project. I use that for storing my dates in a database. See the tiUtils.pas unit in the tiOPF project on SF.net: http://tinyurl.com/69a5nf See the following functions: tiDateTimeAsIntlDateStor tiDateTimeAsIntlDateDisp tiIntlDateStorAsDateTime tiIntlDateDispAsDateTime Hope this helps...

[fpc-pascal] Date conversion question
Hello, I have a little project in which I need to convert various string encoded in various date format to TDateTime. For the same date, I'll have: '2008-05-10 21:49:21' '2008:05:10 21:49:21' '2008-05-10T19:49:21Z' I am no expert with date manipulation so I am asking: For the first type of string; DateSeparator:= '-'; ShortDateFormat:= ':MM:dd'; StrToDateTime(str_date); //gets converted. For the second type of string; ShortDateFormat:= ':MM:dd'; DateSeparator:= ':'; StrToDateTime(str_date); // will trigger an exception Is that intented or normal? Is there a method available except replacing the ':' by '-' in the date part? For the third type of string; Should I convert the third string and remove the T and Z chars or are there any others methods available? Thanks in advance. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
