LIB from Visual C++ cannot link to UPP package [message #5677]

Hi!

Is it basically possible to create a library with Visual C++ and then use it in a UPP package?

I tried and copied the lib-file and header-files into the package folder and then included it in the package. I also change the settings und 'Build Methods' to include the path to my lib-file, but I always get problems during linking. Some unresolved references.

Thanks for any help.

Isn't it possible that your lib contains some references to other libs?

That might be possible. I thought libs are statically linked and so should include everything, but I will check it this area.

Thanks for the super fast answer.

Well, you decription of the process is a little bit fuzzy to me.

The right simple way how to use external library is to add it in package organizer to the package that needs it - right click to the right pane and choose "Add library...".

That's exactly what I did and when linking I get a nice message:

Linking...
\mingw\lib\gcc\mingw32\3.4.2\..\..\..\..\mingw32\bin\ld.exe: cannot find -llibboost_filesystem-mgw-s-1_33_1.lib
collect2: ld returned 1 exit status

And I have added the c:\upp\myapps\mysqldemo dir in Package Organizer->Link Options

-Lc:\upp\myapps\mysqldemo

Hi,

If you are using MinGW in Ultimate++, there will be problems when linking Visual C++ libs with your project. This is because the MinGW .a library files are not compatible with Visual C++'s .lib files.

If you use MSC7.1 or MSC8 in Ultimate++, there should be no problems.

Hope this helps.

Best Regards,
Yeoh

Actually, I built Boost using both mingw and VC so I have two different libs. But the same error is displayed in VC also.

Linking...
LINK : fatal error LNK1104: cannot open file 'libboost_filesystem-vc71-sgd-1_33_1.lib'

Hint: There is "Verbose" option in Setup menu. Activate that to see which commandline options are actually send to compiler and linker.

Fastest way how to figure out what is wrong.

Hello,

Sorry about my incorrect assumption earlier.

From your linker error, it looks like the linker cannot find the .lib file. Is the file libboost_filesystem-vc71-sgd-1_33_1.lib created? And in which folder is it in? You'll probably need to re-check your libraries path.

Best Regards,
Yeoh

From the error message I get, that's the assumption I made too.

Checked and re-checked the paths and filenames (copy/paste) but still getting the same message, no matter if I use the mingw or the VC .lib

Here is what I do:

a) Build-Methods-> LIB-directories for lib files-> Copy & Paste the path from my explorer window.
C:\Dev-Cpp\include\boost\bin\boost\libs\filesystem\build\lib boost_filesystem.lib\mingw\release\runtime-link-static
b) Package Organizer->New Libraries-> Copy & Paste the lib filename from the previous explorer window.
libboost_filesystem-mgw-s-1_33_1.lib

F7 (Build)

I Even tried to put the full path and filename in Package Organizer, but I get the same message.

That's all

(Same logic works in Dev-C++)

Have you tried the verbose mode to see what is happening?

Yes, I did, nothing helpful, the -lc:\...\boost...lib parameter is included but I get the same error.

Then the problem is most likely with library format or name.

As the first thing I would try to rename the file to some shorter name (just as experiment).

Thanks, but already tried it.

This is very strange.

Have you tried to generate a makefile in Dev-C++ and in U++ and compare the compiler and linker settings?

That's beyond my skills.

In order to build the boost libraries I followed the boost build instructions and used the "bjam" utility. Afterwards I just included the lib in my Dev-Cpp project and it just worked.

uses
	CtrlLib,
	MySql,
	Sql;

options
	-IC:\Dev-Cpp\include\boost,
	-Ic:\upp\myapps\mysqldemo;

file
	MysqlDemo.h,
	main.cpp charset "windows-1253",
	MysqlDemo.lay;

mainconfig
	"" = "GUI";

That's my upp file, I don't see any linker options in here. Should they be included?

If "Be verbose" is enabled then I can see the -L flag appended which means that the library dirs are included.

I think I suspect where the problem is...

You have added -l option to the build method compiler options. But that is not right, those options are just to compile the file, not for linking. (Please check if in verbose mode there is -l in _LINKING_ step).

You should add it in package organizer as "Add library...".

Well, you are showing settings for mingw build method, but in your package organizer, there is .lib extension for the library.

That cannot work.
