CC name mangling confusion

kovalMar 20 2012 — edited Mar 22 2012

While compiling QtCreator using Solaris Studio I have come across to an interesting issue with name mangling:
Class QmlDesigner::AbstractView contains method

ModelNode createModelNode(const QString&, int, int, const PropertyListType&, const PropertyListType&, const QString&, ModelNode::NodeSourceType);

It is exported from the implementation file abstractview.cpp and used in qmlstate.cpp file linked to the same library
nm -C applied to the resulting shared object gives:

I have marked characters which are different (7 replaced with rk5 and 8 with 9B)

Demangled output shows the same prototype but manglings are different (11 coming from abstractview.cpp and UNDEF from qmlstate.cpp)

I guess if the function were mangled same in both cases the linker would resolve it and the resulting shared object would not have undefined symbols

Is there any document describing mangling rules of CC compiler? I have once read an article at Oracle sites about ABI stability which mentions publishing such a document but I cannot google it anywhere.

Where does the difference come from? is it a bug in mangler or demangler?
I think mangling should be a 1-to-1 function not allowing two different codings for same prototype. Maybe the demangler does not correctly decode the small difference in the symbols above which decoded properly would indicate what the compiler "thought" of the function in while exporting and using as extern

I have noticed the same difference in mangling for Sun Studio 12 (CC: Sun C++ 5.9 SunOS_sparc Patch 124863-01 2007/07/25)
Solaris Studio 12.2 (CC: Sun C++ 5.11 SunOS_sparc/i386 2010/08/13)
and Solaris Studio 12.3 (CC: Sun C++ 5.12 SunOS_i386 2011/11/16)

the path to the wlserver_10.3\server\lib folder is wrong. It should be

C:\oracle\Middleware\jdeveloper\wlserver_10.3\server\lib

if your properties are right.

Timo

Tony007

where must i set the path to the wlserver_10.3

Timo Hahn

Check the build.properties. This is all you need to do.

# Base Directory for library lookup
jdeveloper.home=C:\oracle\Middleware\jdeveloper

should be

# Base Directory for library lookup
jdeveloper.home=C:/oracle/Middleware/developer

and check if this is reals the path where you installed jdev.

Timo

Tony007

the path i install jdeveloper is C:\oracle\Middleware\jdeveloper

Tony007

i change my build path to
# Master Ant properties file for Fusion Order Demo
# All build files refer to this master list of properties
# Continuous builds override these settings
# $Id: build.properties 812 2007-02-20 07:14:33Z lmunsing $

OK, I have a typo in my last post. I delete the 'j' from jdeveloper.

# Base Directory for library lookup
jdeveloper.home=C:/oracle/Middleware/jdeveloper

Please see that I use '/' instead of your '\' you use. I tested the scripts an they work if you set the properties to the correct values.

Looks like you have not used three right credentials for the SYSTEM user of the db.
Check if you have the right password and try again.

Timo

Tony007

i did use the right password because when i run drop all i get this massage but when i run buildall all i get the other error

Not sure what went wrong but

[sql] java.sql.SQLSyntaxErrorException: ORA-00911: invalid character>
points to an error in your set up or your properties.

Which db are you using?

User,
this is not going further if you don't try to find out what is responsible this invalid 'character error'. It is definitely something on your machine as I can run the buildAll target without any error.
If our are sure us used the right credentials, check that you did not add a special (may be invisible) character to the FOD user or password.
Again I'll ask fro information about the db you are using?
Do you use any special language settings?

Timo

Tony007

the db is oracle enterprise 11g if i may ask where is the detail of user FOD the password how is this created

You changes the defaults so now the script can't log in into the new schema.

What are we doing wrong or it as usual will not work as it says in readme and promo? :)))
