pbx2pbd90 Failed!

[loafth]

I use Borland C++ compiler to try one PBNI example
"PNBIHello". I use comand line "bcc32 -WD pbnihello.cpp
pbx_hello.cpp" to created pbnihello.dll with 7 warning
message like "... Parameter 'xxx' is never used in function
__xxx ...", then I copy it to a new folder to create pbd by
using command "pbx2pbd90 c:\pb9\hello\pbnihello.pbd
c:\pb9\hello\pbnihello.dll", it return message:
"Can not get function(PBX_GetDescription) entry point.
Adding file: c:\pb9\hello\pbnihello.dll into
PBD:c:\pb9\hello\pbnihello.pbd ... Failed!"

Is this a compiler problem? I cannot use bcc32 here?

TIA

I tried using bcc before and had no luck. I was told to rebuild the pbni
libraries using the borland stuff, but I still never got it working and just
convinced the boss to get VC++. If you have any luck I for one would
appreciate it if you posted how you did it in here.

PBNI uses advanced template syntax that is not supported by all C++
compilers -- verify that the version of BCC that you're using supports
the latest ISO template syntax.

According to Borland C++ Compiler 5.5 doc, it should support
latest ISO syntax. ("The Borland C++ Compiler 5.5 (BCC) is
the foundation and core technology of C++Builder 5. Borland
C++ Compiler 5.5 is a blazingly fast 32-bit optimizing
compiler. It includes the latest ANSI/ISO C++ language
support including, the STL (Standard Template Library)
framework and C++ template support and the complete Borland
C/C++ Runtime Library (RTL). Also included in the free
download are the Borland C/C++ command line tools such as
the high performance Borland linker and resource compiler.")
I can use BCC32 command line to create dll but with warning
message as following:

Then, I run the pbx2pbd90 and it was failed:
----------
C:\pb9\hello>pbx2pbd90 c:\pb9\hello\pbnihello.pbd
c:\pb9\hello\pbnihello.dll

Can not get function(PBX_GetDescription) entry point.
Adding file: c:\pb9\hello\pbnihello.dll into
PBD:c:\pb9\hello\pbnihello.pbd ... Failed!

---------
looks like pbx2pbd90 cannot find the _main() of
PBX_GetDescription(). but compiler does not get this error.
Is this caused by compiling defects (warning)?

Use DependencyWalker (www.dependencywalker) to verify that you have a
function by that name exported from the DLL without C++ name mangling --
you may need to add a .def file to your project.

[Roy Kiesler [TeamSybase]]

Not sure what ___CPPdebugHook is doing... otherwise looks OK.

Can you provide your source CPP file?

Can you debug the DLL and see if you can trap the call the
PBX_GetDescription when pbx2pbd90 is invoked?

How to debug DLL? using Dependency? VCC?
By the way, did you get same problem by using bcc32? I guess
if I create dll without any warning, it may be fine. I am
trying to get another C++ compiler.

TIA

[Roy Kiesler [TeamSybase]]

You debug the DLL using your C++ debugger by attaching to the
pbx2pbd90.exe process. I'm not using Borland, so I can't really tell you
how its debugger works, but in VC++, you can start a debug session using
any executable that ends up loading the DLL you're debugging into memory
(you just put a break point in dllmain()

It should be a calling convention problem.   In pb source code, it used following ways to get the entry point.

                P_PBX_GetDescription registerPspp = (P_PBX_GetDescription)GetProcAddress(d_hinst,
                        "_PBX_GetDescription@0");


The exported function name is "_PBX_GetDescription@0" because it used __stdcall  calling convention.

[bluetlck]

you can create a fie named project1.def ,then add it to bcb
project.

the file's content is:
EXPORTS
_PBX_GetDescription@0 = PBX_GetDescription

Good Luck!
