DLL Properties @ Windows7 using g++

Hi all,

I constructed a DLL @ Windows7 using g++ and Eclipse. I want to show the version of the DLL file at the properties:details windows in Windows Explorer (this way my client can see what version he is currently using).

How do I do this? (I am not using Visual Studio!)

You use a resource file, and resource compiler.

MS resource compiler | MinGW

VERSIONINFO resource (Windows)

gg

I'm guessing that you mean just to set the version so that it will show as one of the details? If you're not using Visual Studio, then you'll have to make this resource yourself (assuming MinGW with Dev-C++ or Codeblocks)

Create a file with a .rc extension. The resource name is VERSIONINFO.

so... a resource like...

Code:

1 VERSIONINFO FILEVERSION 1,0,0,0 PRODUCTVERSION 1,0,0,0

EDIT:: aww... beaten with a stick D:

DONE, but not working!

Code:

EDIT:: aww... beaten with a stick D:

Done! But nothing happened :tongue:. I followed these steps:

1.Created my .rc file

Code:

#define VER_FILEVERSION 3,10,349,0 #define VER_FILEVERSION_STR "3.10.349.0\0" #define VER_PRODUCTVERSION 3,10,0,0 #define VER_PRODUCTVERSION_STR "3.10\0" #define VER_COMPANYNAME_STR "MS" #define VER_FILEDESCRIPTION_STR "WORKINGDLL" #define VER_INTERNALNAME_STR "tdllinfo" #define VER_LEGALCOPYRIGHT_STR "2012" #define VER_LEGALTRADEMARKS1_STR "All rights reserved" #define VER_LEGALTRADEMARKS2_STR "legal trademarks 2" #define VER_ORIGINALFILENAME_STR "tdllinfo" #define VER_PRODUCTNAME_STR "dll" #ifndef DEBUG #define VER_DEBUG 0 #else #define VER_DEBUG VS_FF_DEBUG #endif VS_VERSION_INFO VERSIONINFO FILEVERSION VER_FILEVERSION PRODUCTVERSION VER_PRODUCTVERSION /*FILEFLAGSMASK VS_FFI_FILEFLAGSMASK FILEFLAGS (VER_PRIVATEBUILD|VER_PRERELEASE|VER_DEBUG) FILEOS VOS__WINDOWS32 FILETYPE VFT_DLL FILESUBTYPE VFT2_UNKNOWN*/ BEGIN BLOCK "StringFileInfo" BEGIN BLOCK "040904E4" BEGIN VALUE "CompanyName", VER_COMPANYNAME_STR VALUE "FileDescription", VER_FILEDESCRIPTION_STR VALUE "FileVersion", VER_FILEVERSION_STR VALUE "InternalName", VER_INTERNALNAME_STR VALUE "LegalCopyright", VER_LEGALCOPYRIGHT_STR VALUE "LegalTrademarks1", VER_LEGALTRADEMARKS1_STR VALUE "LegalTrademarks2", VER_LEGALTRADEMARKS2_STR VALUE "OriginalFilename", VER_ORIGINALFILENAME_STR VALUE "ProductName", VER_PRODUCTNAME_STR VALUE "ProductVersion", VER_PRODUCTVERSION_STR END END BLOCK "VarFileInfo" BEGIN /* The following line should only be modified for localized versions. */ /* It consists of any number of WORD,WORD pairs, with each pair */ /* describing a language,codepage combination supported by the file. */ /* */ /* For example, a file might have values "0x409,1252" indicating that it */ /* supports English language (0x409) in the Windows ANSI codepage (1252). */ VALUE "Translation", 0x409, 1252 END END

2. "Compiled" it:

Code:

windres myresfile.o myresfile.rc

Then my myresfile.o was created.

3. Included it on my build:

Code:

g++ -shared -p -pg -o tmydll.dll Sources\Comm.o Sources\Serial.o Sources\Protocols.o ..\..\Resources\myresfile.o

4. Everything went ok, but the properties of my DLL shows:
Attachment 11675
(sorry my Windows is in portuguese...)

5. I wanted something like:
Attachment 11676

Am I doing something wrong???

>> Windows is in portuguese...
You added an English version info block. Add a Portuguese block.

Change
BLOCK "040904E4"
to
BLOCK "041604E4"

Change
VALUE "Translation", 0x409, 1252
to
VALUE "Translation", 0x416, 1252

0x416 is the LangID for "Portuguese (Brazil)".

gg

Just a guess, but maybe the G++ linker is throwing out the resource object because it appears to be unreferenced.

Language correction

Language corrected! I noticed that before, I wanted this thing working before writing real values to the Resource File... :tongue:

What?? Well, g++ goes not give me any error at all, at the end of build. What do you mean by unreferenced?

My command is something like

Code:

g++ -shared -p -pg -o tmydll.dll Sources\Comm.o Sources\Serial.o Sources\Protocols.o ..\..\Resources\myresfile.o

where myresfile.o is the object file created by a windres compilation.

Any clue?

If you are still having problems, I suggest opening your DLL in a resource editor and compare its version resource with one from a DLL that "works".

Why would it? Having unreferenced stuff is not an error.

[B]What do you mean by unreferenced?

Suppose you have a .obj file that contains a symbol called "Foo" but absolutely nothing in your program/DLL refers to Foo. In this case the linker may silently discard the entire .obj because nobody is using it. I was speculating that this might be happening here, because a resource object does not contain any referenced symbols and so a naive linker might toss it out.

Of course, looks like you discovered that it was a language problem.

Not exactly!

Not exactly! This was not the solution (sorry I made you misunderstand), but I managed to find a way to make it work. I'll explain in my next post.

Solved!

I managed to make it work, but I don't know what I did right...
(I think the trick is including the windows.h header) I used the ResEdit software on a random DLL I took from C:\Windows\. Using that one as example, I composed the following .rc file:

Code:

#include <windows.h> // // Version Information resources // // Further references: // http://msdn.microsoft.com/en-us/library/windows/desktop/aa381058(v=vs.85).aspx // // LANGUAGE LANG_PORTUGUESE, SUBLANG_PORTUGUESE_BRAZILIAN 1 VERSIONINFO FILEVERSION 1,0,0,0 PRODUCTVERSION 1,0,0,0 FILEOS VOS_NT_WINDOWS32 FILETYPE VFT_DLL FILESUBTYPE 0 FILEFLAGSMASK VS_FF_PRIVATEBUILD FILEFLAGS 0x00000000 { BLOCK "StringFileInfo" { BLOCK "041604E4" { VALUE "Comments", "commmented" VALUE "CompanyName", "myCompanyName" //Required values: VALUE "FileDescription", "BlahBlahBlah" VALUE "FileVersion", "1.0.00" VALUE "ProductVersion", "1.0.00" VALUE "InternalName", "filename.dll" VALUE "LegalCopyright", "Copyright © 2012" VALUE "LegalTrademarks", "2012" VALUE "OriginalFilename", "filename_original.dll" VALUE "ProductName", "product" VALUE "PrivateBuild", "pb" } } BLOCK "VarFileInfo" { /* The following line should only be modified for localized versions. */ /* It consists of any number of WORD,WORD pairs, with each pair */ /* describing a language,codepage combination supported by the file. */ /* */ /* For example, a file might have values "0x409,1252" indicating that it */ /* supports English language (0x409) in the Windows ANSI codepage (1252). */ VALUE "Translation", 0x416, 1252 } }

Next, I used the windres(from the MinGW suite) command to build the .o object file:

Code:

windres ../Resources/resources.rc ../Resources/resource.o

Then I compiled it:

Code:

g++ -L../../Libs -shared -o myDll.dll Sources\a.o Sources\b.o Sources\c.o Sources\d.o ..\Resources\resource.o -lmylib

After that, the file information was filled at my O.S.:wink:

See Ya!:cool:
