xe2 bpl installation problem , need help

[mitchellhu]

Windows10
Delphi Xe2 update 4
libarary path is added
while installation Python_D150.bpl
IDE raise Error: [DCC Error] WrapDelphi.pas(2789): E2003 Undeclared identifier: 'TypeData'
and point to Error line: WarpDelphi.pas line 278:
if (RttiParam.ParamType = nil) or (RttiParam.ParamType.Handle = nil) or (RttiParam.ParamType.Handle.TypeData = nil) then
Exit;

I check out the Unit Sytem.Typinfo found a Strange place:

PPTypeInfo = ^PTypeInfo;
PTypeInfo = ^TTypeInfo;
TTypeInfo = record
Kind: TTypeKind;
Name: ShortString;
{TypeData: TTypeData}
end;

the TypeData section is be marked with a curly bracket in Delphi Xe2 !!!
I'm not sure if it makes trouble.

[pyscripter]

Does it help to replace

RttiParam.ParamType.Handle.TypeData

with

GetTypeData(RttiParam.ParamType.Handle)

The change needs to be applied to a couple of lines below.

[mitchellhu]

pyscripter ：
1.compile pass with Replace with GetTypeData(RttiParam.ParamType.Handle) and GetTypeData(RttiParam.ParamType.Handle).eltype.
2.But now IDE debugger shows : Can't load package Python_D150.bpl.
I can't find Python_D150.bpl. in the python4delphi-master.zip files,!!!
Where can I get the Python_D150.bpl.?
Thanks

[pyscripter]

Python_D150.bpl is the name of the compiled package file that Delphi is looking to load. It is not part of the distribution. The package file Python_D.dpk contains a series of IFDEFs with LIBSUFFIX directives, For XE2 the following should apply
{$IFDEF VER230}{$LIBSUFFIX '160'} {$ENDIF}
and the generated package should be called Python_D160.bpl
Can you check C:\Users\Public\Documents\Embarcadero\Studio\16.0\Bpl for Python_D*.bpl.

A workaround is to replace all the IFDEFS in the package file with {$LIBSUFFIX '160'} using an editor and then load and compile the package again.

Pyscripter:
I do not flow your instruction very clearly.
I found Python_D160.bpl in path C:\Users\Public\Documents\RAD Studio\9.0\Bpl。this path is a little different from your point out one.
I open the Python_D.dpk with NotePad++ , then it shows as below:
package Python_D;

{$R '......\Source\PythonEngine.dcr'}

end.

Should I replace all $LIBSUFFIX '120' with $LIBSUFFIX '160' then save it.
and load Python_D.dpk and compile it?
Sorry for my bad English ability.
Thanks

Yes that is what I was suggesting. It appears that the package is compiled to Python_D160.bpl but then Delphi tries to load Python_D150.bpl. Don't know why.

[mitchellhu]

pyscripter:
Even modify Python_D.dpk as below still does not work.
{$IFDEF VER090}{$LIBSUFFIX '160'} {$ENDIF}
{$IFDEF VER170}{$LIBSUFFIX '160'} {$ENDIF}
{$IFDEF VER160}{$LIBSUFFIX '160'} {$ENDIF}

While you load it, you will seed the Python_D150.bpl in the project manager.
I think the old versions may not be proved they can work fine!!!

[pyscripter]

Please replace all {$IFDEF VERxyz} with just one line

{$LIBSUFFIX '160'}

and try again.

[mitchellhu]

pyscripter:
still does not work, the bpl name does not change to Python_D160.bpl .
Why LibSuffix '160' does not work !!!!
change as below:
package Python_D;

{$R '......\Source\PythonEngine.dcr'}
{$IFDEF IMPLICITBUILDING This IFDEF should not be used by users}
{$ALIGN 8}
{$ASSERTIONS ON}
{$BOOLEVAL OFF}

end.

Libsuffix if probably set wrongly in the project file. You can either

• Change libsuffix in the project options or
• Delete all files in the package folder except Python_D.dpk and open the above file again in Delphi.

[mitchellhu]

pyscripter :

1. About the fisrt suggestion, I can not find any option with libsuffix.
2. Second suggestion works, it is Python_D160.bpl now, and can be installed. （Could you tell why, I want to lean some thing)
3. Test Demo1, but IDE shows [DCC Fatal Error] Unit1.pas(11): F1026 File not found: 'PythonEngine.dcu',
   How come? already set the lib_path D:\Components\P4D\Source and D:\Components\P4D\Source\vcl,
   This is a very strange problem to me.

[pyscripter]

3. already set the lib_path D:\Components\P4D\Source and D:\Components\P4D\Source\vcl,
This is a very strange problem to me.

Have you set it for all targets (32 bits, 64bits)?

[mitchellhu]

Pyscripter:
I set the libPath both 32 bits and 64bis. See. Pics as below.
source path:

32bits libpath:

64bits:libpath

[pyscripter]

Check Project, Options, Compiler, Unit Output directory.
Can you locate PythonEngine.dcu in the P4D subfolders?

[mitchellhu]

pyscripter:

1. I add unit Output directory and compile the project, then got an Error again,
   [DCC Fatal Error] Unit1.pas(11): F2048 Bad unit format: 'D:\Components\P4D\Source\PythonEngine.dcu' - Expected version: 23.0, Windows Unicode(x64) Found version: 23.0, Windows Unicode(x86) : see the picture as below
   

2. According to the Error. I switch the Target platform from 64bit to 32bit. then IDE seems to find those Pythonxxx.dcu files.
   but raise a new Error: Error 87: Could not open Dll "python33.dll", close the Error message,
   IDE raise another Error: python could not be properly initialized, We must quit;

3. Use Python IDLE to get Python running in 64 bit.

import struct
print(struct.calcsize("P")*8)
64

so, I try to compile Delphi Project Demo1 with 32bit platform, that is the reason why IDE can't find python33.dll. Is it right?
But, I can.t compile Demo1 in 64bit platform because IDE says the xxx.dcu file is not 64it format!!!
What a mess?

[pyscripter]

1. I add unit Output directory and compile the project, then got an Error again,
   [DCC Fatal Error] Unit1.pas(11): F2048 Bad unit format: 'D:\Components\P4D\Source\PythonEngine.dcu' - Expected version: 23.0, Windows Unicode(x64) Found version: 23.0, Windows Unicode(x86) : see the picture as below

You need to build the project to avoid this error.
