bgd.dll

[czerny]

I am trying to make a working import library for 'bgd.dll', a precompiled version of the gd-library.

In the following I have reduced the output to two typical functions to reduce the material.

Code: [Select]

>podump /EXPORTS bgd.dll

Dump of bgd.dll

File type: DLL

There seems to me cdecl functions (gdFontGiant) and stdcall functions (gdFontGetTiny) in this dll.

Code: [Select]

polib bgd.dll /MACHINE:X86 /makedef:bgd.def

POLIB: fatal error: Corrupt library: 'bgd.dll'.

This command does not work as expected!
So I first made an import library with:

Code: [Select]

polib bgd.dll /MACHINE:X86 /out:bgd.lib

and afterwards

Code: [Select]

polib bgd.dll /MACHINE:X86 /makedef:bgd.def /out:bgd.lib

which produced

Code: [Select]

LIBRARY "bgd.dll"
EXPORTS
"gdFontGetTiny@0" ; bgd.dll
"_gdFontGiant" DATA ; bgd.dll

than I in got

Code: [Select]

podump /IMPORTS bgd.lib

Dump of bgd.lib

File type: LIB
bgd.dll: gdFontGetTiny@0 (gdFontGetTiny@0)
bgd.dll: gdFontGiant (_gdFontGiant)

SUMMARY
      14 .idata$2
      14 .idata$3
       4 .idata$4
       4 .idata$5
       8 .idata$6

all this looks a little inconsistent to me. And it does not work

Code: [Select]

POLINK: error: Unresolved external symbol '_gdImageCreateTrueColor@8'.

I tryed all variants of PeExp2Def

Code: [Select]

(function)
LIBRARY bgd.dll
EXPORTS
gdFontGetTiny@0
gdFontGiant

("function")
LIBRARY bgd.dll
EXPORTS
"gdFontGetTiny@0"
"gdFontGiant"

(function = function@x)
LIBRARY bgd.dll
EXPORTS
gdFontGetTiny = gdFontGetTiny@0
gdFontGiant

(function@x ordinal)
LIBRARY bgd.dll
EXPORTS
gdFontGetTiny@0 @10
gdFontGiant @11

But that does not work too.

What I am doing wrong?

gdFontGetTiny@0 -> __stdcall decorated name takes zero arguments (0 bytes)
"_gdFontGiant     -> __cdecl.

I'm not sure that you can use that library if you don't have a full header.

What I am doing wrong?

That dll seems to be for MinGW.
gdImageCreate@8 isn't normal __stdcall function name in win32,  _gdImageCreate@8 or gdImageCreate is for win32.
_gdFontGiant is for data.
__declspec(dllimport) in header also means to use gdImageCreate

EDIT: some bgd.dll depends too much msvcrt.dll, so it can be useless with PellesC (different FILE struct?).

I have the header files. Problem is to create a working import library.

with a def file

Code: [Select]

_func@x = func@x

the code compiles. But than 'func' (not 'func@x') is searched for and not found.
