the troubles begin :roll:

I generate a DLL "operations_x86.dll" as well as the file "operations_x86.lib"
here is the code of my DLL

Code: Select all


 ; ; ; 
 ;  ; Code "operations.dll "  a compiler en DLL
     ProcedureDLL.i AttachProcess(Instance)
     EndProcedure   
     ; Called when the program release (free) the DLL    ;
     ProcedureDLL.i DetachProcess(Instance)
     EndProcedure   
     ; Both are called when a thread in a program call or release (free) the DLL    ;
     ProcedureDLL.i AttachThread(Instance)
     EndProcedure  
     ProcedureDLL.i DetachThread(Instance)
     EndProcedure
     ; ********************************************
      ProcedureDLL.i A(a,b)
  	 ret=a+b
      		ProcedureReturn ret
      EndProcedure
      ProcedureDLL.i s(a,b)
  	 Ret= a-b
      		ProcedureReturn Ret
      EndProcedure
      ProcedureDLL.i d(a,b)
  	 Ret=a/b
      		ProcedureReturn Ret
      EndProcedure
      ProcedureDLL.i M(a,b)
  	 Ret=a*b
      		ProcedureReturn Ret
      EndProcedure

the 4 basic operations in procedures, nothing very complicated!

then I test with this code:

Code: Select all


    ; 
     ; 
      Import "operations_x86.lib"
      		a(a,b)
      		s(a,b)
      		d(a,b)
      		M(a,b)
      EndImport 
      
   
   
    ;   Utilisation
   debug a(5,8)
   debug S(8,2)
   debug d(10,8)
   debug M(5,8)

it does not work ! Any ideas ??

the import of the file Lib beside its DLL, must work, out, it does not work ...
contrary to what the Doc says .

Is there a special writing to respect ??

Dll Exports/Imports are case sensitive.

Import "operations_x86.lib"
A(a,b)
s(a,b)
d(a,b)
M(a,b)
EndImport

Thank you I corrected the Case sensitive , But

but it does not work better because in fact the code does not even launch
I have a POLINK error
Error: LinkerPOLINK: error: Unresolved external symbol 'a'.
POLINK: error: Unresolved external symbol' .
.....
.....
fatal error : 4 unresolved external (s).

Thanks

Have you choose the same compiler for dll and for exe?
If so what version are you using?

avec le compilateur et le Flag "/Import"+chr(34)+name_file.s+chr(34)
je genere un fichier d'importation ..... . ( a partir d'un fichier PB source d'une DLL )

mais, ou dois t'on le mettre, pour qu'il soit reconnu par PB ??
comment dois t'on s'y prendre, pour s'en servir ?

la doc dit :

-i, --import, /IMPORT "Fichier": crée un fichier d'importation au nom de fichier donné. Seulement un seul bloc Import/EndImport autorisé dans le fichier. Les fonctions importées seront chargées automatiquement pour tous les projets de PureBasic.

comment faire pour que mes projets puissent se servir de ce fichier d'import ?

Google translate :

with PBcompiler and Flag "/Import"+chr(34)+name_file.s+chr(34)
I generate an import file ..... (from a source PB file of a DLL)

but, or should you put it, so that it is recognized by PB ??
how should we go about it, to use it?

the doc says:

-i, --import, / IMPORT "File": creates an import file for the given file name. Only one import / endImport block allowed in the file. The imported functions will be loaded automatically for all PureBasic projects.

how to make my projects use this import file?

This is what I use to create import files for missing API functions... Just adapt to your own DLL

(Run from IDE and restart afterwards)
