hbmk2 bug ?

[Felix Pablo Grande]

Hello,

when creating an import library with mingw, the library created is the same size as the dll used. On the other hand, with Borland it is not like that.

Is it a hbmk2 bug with mingw?

I have used unrar.dll http://www.winrar.es/descargas/32/descargar-unrar-dll-para-windows-en-ingles

Running the following command: hbmk2 -hbimplib unrar.dll

With MinGW: UnRar.dll size(262Kb) libUnRar.a size(262Kb)

With Borland: UnRar.dll size(262Kb) UnRar.lib(2Kb)

Thanks in advance !

Best regards,

Hello Felix Pablo,

You should use another tool for your conversion from the dll to a library file.

I've converted this dll with Lib2A tool successfully.

With MinGW: UnRar.dll size(261Kb) libUnRar.a size(10Kb)

My unrar.def file is below:

LIBRARY "UnRAR.dll"

EXPORTS

RARCloseArchive@4

RARGetDllVersion@0

RAROpenArchive@4

RAROpenArchiveEx@4

RARProcessFile@16

RARProcessFileW@16

RARReadHeader@8

RARReadHeaderEx@8

RARSetCallback@12

RARSetChangeVolProc@8

RARSetPassword@8

RARSetProcessDataProc@8

HTH,

Hi Grigory,

we can generate def file with MinGW gendef.exe

gendef UnRar.def

;
; Definition file of UnRAR.dll
; Automatic generated by gendef
; written by Kai Tietz 2008
;
LIBRARY "UnRAR.dll"
EXPORTS
RARCloseArchive@4
RARGetDllVersion

RAROpenArchive@4
RAROpenArchiveEx@4
RARProcessFile@16
RARProcessFileW@16
RARReadHeader@8
RARReadHeaderEx@8
RARSetCallback@12
RARSetChangeVolProc@8
RARSetPassword@8
RARSetProcessDataProc@8

After this, we can use dlltool to create libunrar.a

dlltool.exe -d UnRar.def -D UnRar.dll -k -l libUnRar.a

Thanks for your time and help.

Hi Klas,

sorry but I think hbmk2 has an error when creating import libraries with MinGW.

hbmk2 -hbimplib unrar.dll

Because of this I have published the post.

Sorry for the inconvenience.

Hi,

as far as I remember, MinGW is capable to use .dll files as lib files.
You need just copy .dll to .a file. Try byte compare these files to
check the assumption (fc /b filename1 filename2).
Not space efficient, but useful. It should not make any influence on
size of the final executable.
