Обсуждение: RE: [HACKERS] libpq and libpgtcl in Windows

Hiroshi,
    I've got a bug report for you. On a Win95 machine running
Tcl/Tk 8.1, the dll does not load correctly. A "load libpgtcl.dll"
at the "wish81" console gives a :
<Couldn't load file "libpgtcl.dll": invalid argument>.
But it works file on Tcl/Tk 8.0 for Windows. Apparently the DLL
interface in Tcl/Tk 8.1 is a little different, I'm not sure what
it is. Are you using Microsoft Visual C++ or a Borland Compiler?
The DLLs that Borland puts out are a little different but for the
most part I have'nt to many problems with them. The Tcl that
Scriptics puts out is compiled in Microsoft Visual C++.

I'll look at your code this weekend.

D.

Hi all

I made dll's(libpq.dll,libpgtcl.dll) only for pgaccess.
It is a temporary solution for quick fix and the solution for general
use
is necessary.

I made libpgtcl.dll ignoring NOTIFY functionality(not used in pgaccess).
Sorry,I'm not a Tcl expert and can't provide proper code for NOTIFY
functionality in Windows.

Another problem exists between libpq and libpgtcl in Windows.
Libpgtcl references global data pgresStatus[] in libpq when using
pg_result -status command.
But in Windows libpgtcl doesn't reference pgresStatus[] in the same
way as UNIX and pg_result -status returns improper values.

Any ideas ?

In my temporary solution for pgaccess,I used a function interface
between libpq and libpgtcl instead of global data.

Thanks

If the version of Tcl is different,the name is different(tcl76.dll,
tcl80.dll,tcl81.dll etc).
The dll I provided is only for Tcl8.0(tcl80.dll).
For Tcl8.1 another dll is necessary.
The dll for Tcl8.1 is necessary ?

Tcl/Tk 8.1 is currently in beta stage, but a lot of programmers choose
to "taste" the new flavor of Tcl/Tk 8.1
If it's not so hard, maybe it would be better to deliver DLL for all
currently available versions.
