HAPPY NEW-YEAR to everybody on this Newsgroup,
Please can anybody help me to discover my Error in reasoning, I still =
do?
I have "condensed" my Problem from the big Project to nearly its smallst =
Size, but
I'm still not able to get over my mistake:
- Do I miss a Library? OR
- Have I not given the correct "Link"/""Reference-File" to =
Compiler/Linker? OR
- Do I still missing the correct Idea, to solve the Problem? OR
- ........?
Your HELP is very appretiated !!!!!!
First, How the Project is organised:
Second, The source code: (It's contained in 3 files):
If I compile, I get 4 Errors with the identical Header:
undefined reference to `std::basic_string<wchar_t, =
std::char_traits<wchar_t>, std::allocator<wchar_t> >::basic_string()'
As you can see in the following Consol-Windows, the Errors appear, in =
the LINKER part:

Peter,
It looks like you have a problem with gcc not finding the default
locations for the include and library files. The -I option in the gcc
command specifies this. The CDT tries to help by locating the directory
they are supposed to be in but it is up to the programmer to make sure
they are correct.
What you need to do is look at he first error message and try to
determine why it failed. Sometimes fixing the first error corrects all
of the errors as it is a waterfall effect.

E:/Development/Dev.-IDE's/GCC-MinGW/Version0345/bin/../lib/g cc/mingw32/3.4.5/../../../../mingw32/include "
The first error (above) I see is that an include folder is non-existent.
Trace back in your directory path using the file manger on your system
and determine if the directory truly exists.

Dear Ray,
As first, a very extraordinary Thanks for you, and your soon replay !!!
Re-initiated by your answer, I checked the the path for maybe the 10the =
time, visually,
and "found" it "must be correct".
After a while, a thought, YOU must be correct, and now I tested it =
MANUALY!
I opened a CMD-Window on E:, entered the command "cd ", and copied the =
path from the
console to the "cd " command, and now I found the mistake:
It's the last part of the path: "../mingw32/include", exactly the =
finale "include" directory is missing.
Do it Visually, I ended on an absolutely different place !!!
Only for a Test, I created the directory, and compiled again, and now =
the result looks different, but
(maybe - of course!!) NOT better!!!=20
I copied the new, and relevant part below:
.......
ignoring nonexistent directory "/mingw/include/c++/3.4.5"
ignoring nonexistent directory "/mingw/include/c++/3.4.5/mingw32"
ignoring nonexistent directory "/mingw/include/c++/3.4.5/backward"
ignoring nonexistent directory "/mingw/include"
ignoring nonexistent directory "/mingw/include"
ignoring nonexistent directory "/mingw/lib/gcc/mingw32/3.4.5/include"
ignoring nonexistent directory "/mingw/mingw32/include"
ignoring nonexistent directory "/mingw/include"
#include "..." search starts here:
#include <...> search starts here:
E:/Development/Dev.-IDE's/GCC-MinGW/Version0345/bin/../lib/g cc/mingw32/3.=
4.5/../../../../include/c++/3.4.5

E:/Development/Dev.-IDE's/GCC-MinGW/Version0345/bin/../lib/g cc/mingw32/3.=
4.5/../../../../mingw32/include
End of search list.
........
As you may realise, the first error line disappeared, but only to be =
re-incorporated, just before "End of search list." message!
So I searched in the meantime a lot for additional Information, not =
only, how I could maybe change the "CDT general" path=20
for all the different includes, libs, and so on, but I did not succeed =
in any way!!!
=20
Now I hope, you will me allow a few following up questions, because the =
most important for me is all the time, to understand!:
1.) Why is it even important for the Linker to know the "includes" =
again, if compilation before succeeded, and when corresponding=20
".o" files already exist?
2.) Do I really not only miss the correct "include" directory, and of =
course, its content, or is the whole stuff only misplaced.
(Please inspect the three "directory tree" -dumps below for any =
indication).
3.) In case, I'm missing the stuff, to which packages I did not pay =
enough attention? Is there a complete List available for C++?
4.) Or in the other case, that I misplaced the required stuff, is there =
a List about the required directories, there content, and=20
there relative path?
5.) Where is the place to change Directories CDT-wide, and where may I =
find the command to do it?
6.) Finally, at least for the moment:=20
You may have also seen, that the NEW first Error message is =
something absolutely IMPOSSIBLE on MY Computer !!!
a.) I absolutely NEVER created a directory on my Computer with =
the name: "mingw" ANYWHERE, because I NEVER
install any program, other then the OS on its DEFAULT =
place.
So the only directory/program on my whole (on any =
partition) computer is the directory I found in the Deep of the=20
Start-Menu !!!
b.) The CDT declares the missing directories, maybe identically =
with the "other" missing directories, which EXISTS!!,
as APSOLUTE paths, but without any drive/partition, what, =
at least in my opinion, never can be true!!! But why?
Thank you in advance, for all the patience and effort it may require =
from you !, - but the newsgroup is for the moment my=20
only place to get any possible help!
=20
Here my dumps of the relevant Eclipse/CDT directory part for =
inspection/control:
=20
Part 2:
And Part 3:
Thank you once again for all, what you are doing!
Kind Regards=20
Peter.

| Re: Quiz!!:: Find My Error in reasoning: GCC C++ Linker: undefinde reference .... [message #181815 is a reply to message #181800] |

ARGOS,
Actually I'm confused here. Your first post shows compiler errors and
linker errors. Something in your makefile is not right because the first
compilation, AWCharT.cpp, should have aborted the build.
It should not have invoked the gcc to compile HWorld.cpp nor should it
have invoked the linker.
The linker output is complaining about missing functions from the std
library.
I generally concentrate on eliminating all warning and error messages
from the compiler build before I proceed to invoking the linker.
Here are my answers:
> 1.) Why is it even important for the Linker to know the "includes"
again, if compilation before succeeded, and when corresponding

[rhurst]
Only the compiler cares about the location of include files. The linker
cares about the location of library files.
> 2.) Do I really not only miss the correct "include" directory, and
of course, its content, or is the whole stuff only misplaced.

indication).

[rhurst}
I inspected the directory trees and decided there wasn't enough
information there to determine the problem. You also need to show the

following error is confusing:

It shows that gcc is trying to look for include files starting at the
root directory /mingw. I don't believe you have them installed there.

enough attention? Is there a complete List available for C++?
[rhurst]
The real issue here is that the linker cannot find the std library. It
may be as simple as adding the location of the library to the build.
To do this do the following:
MyProject -> Properties -> C/C++ Project Paths -> Add External Library
Browse to the location of the std library and add it.

I am not sure of this one. Typically directories are specified on a per
project basis. However, CDT does get the info from you GCC build and
pre-populates you project with the location of the default directories.

yeah...I mentioned this above too.
Determine the default directories of your gcc build by typing:
gcc -print-search-dirs
This should display the default directories that gcc will search on
every build. Which has nothing to do with CDT. If the default
directories are not correct you can fix it by going to question 3.
Whew...that was quite a bit. I hope it helps.

Dear Christian,
Thank you for your Hint, but it's not the case if you inspect my =
directory-hirarchy.
The directory: "Development" is located directly below the "root" on =
this particular partition.
Dear Ray,
Thank you very much to have answered so many questions from me.
And a special Thank you for "putting" my nose on the correct trace, at =
least for finding=20
the TRUE cause for all my problems.
Your really first answer to my initial question was not absolutely =
correct, as I know now,
in that sense, that the whole thing was only a secondary problem at all.
The real Problem is covered in the picture below:
=20
(As you may note, it's not very much different to the first =
version!)
The Line Number 19 is nothing else as the copied typedef for wstring but =
now called myString.
The Line Number 20 is a similar typedef for wstring but now with int =
instead of wchar_t, also called myString.
AND NOW:=20
IF we comment out Line 20, and invoke Line 19, we have exactly the =
same situation as when I started my "Quiz".=20
- We get exactly the same four missing references during the final =
Linker Step.
BUT, if I comment out Line 19, and invoke Line 20 instead, You won't =
believe: IT WORKS!!!
What's the conclusion of all that?: "libstdc++.a" is NOT knowing =
'wchar_t' !!!!
No, it's true, even if it's hard to belief!
So I started again to search in the Internet, and yes, now I found it:
You can find it under the headline: Compilation fails under =
OpenBSD-current:
( lists.kde.org/?i=3D200504152111.50187%20()%20giezet =
)
The problem got resolved in OpenBSD-current (Apr 15 2005) - =
wchar_t support in libstdc++ was=20
missing - taglib also went into the ports tree.=20
-- Lukas Ratajski - ratajski at gmxpro.net =
<https://mail.kde.org/mailman/listinfo/taglib-devel> .
Or the version for gcc 3.2: gcc 3.2 string<wchar_t> link problem:
( www.cygwin.com/ml/cygwin/2003-02/msg00312.html )
=20
On one side, It's nice to know the cause, but I don't know how to solve? =
And it's indispensable for
the required support of UNICODE !!!Is the source code of the library =
available and if, where?=20
Has somebody else enough experience to do such an improvement?=20
For me it will be for sure not a normal task, in case such could be =
possible.
So once again, Thank you very much for all your effort.
Kind Regards
Peter.
