Missing symbols such as ACE_OS::memset when linking in debug mode using Visual Studio 10

Subject: [linking errors for IDL-associated app lib]: [Missing inlined string function symbols from ACE_OS]

ACE VERSION: 6.1.6

HOST MACHINE and OPERATING SYSTEM:
MS-Windows version 7, 64 bit.
Version of Winsock is unknown.

TARGET MACHINE and OPERATING SYSTEM, if different from HOST:
COMPILER NAME AND VERSION (AND PATCHLEVEL):
Compiler is Visual Studio 10 version 10.0.30319.1

THE $ACE_ROOT/ace/config.h FILE [if you use a link to a platform-
specific file, simply state which one]:
#include "ace/config-win32.h"

THE $ACE_ROOT/include/makeinclude/platform_macros.GNU FILE [if you
use a link to a platform-specific file, simply state which one
(unless this isn't used in this case, e.g., with Microsoft Visual
C++)]:
include $(ACE_ROOT)/include/makeinclude/platform_win32_msvc.GNU

CONTENTS OF $ACE_ROOT/bin/MakeProjectCreator/config/default.features
(used by MPC when you generate your own makefiles):
I am not using MPC, I am using the Visual Studio 10 solution provided,
TAO_ACE_vc10.sln

AREA/CLASS/EXAMPLE AFFECTED:
My application library fails to link when building in debug mode.
The library just contains the code emitted by the TAO IDL compiler
for the IDL files I have in my application.

DOES THE PROBLEM AFFECT:
COMPILATION? No
LINKING? Yes
EXECUTION? No
OTHER (please specify)?
[Please indicate whether ACE, your application, or both are affected.]
ACE and TAO are fine, but my application library fails to link.

SYNOPSIS:
I have an application library which just consists of the code generated
by the TAO IDL compiler for the IDL that I have. This library builds fine
in release mode but it fails in debug mode with missing symbols.
All the missing symbols are from ACE_OS and look like string and memory
functions like strcmp, memset etc.

DESCRIPTION:
I get the link error LNK2019 from Visual Studio 10 when trying to link
my application library in debug mode. The library just contains the code
emitted by the TAO IDL compiler for my application.
Output from the linker is shown below.

I have seen other people report similar problems to this over the years.
Responses have suggested that it might be some sort of problem with the way
inlining is done. Unfortunately, that is not much to go on.

REPEAT BY:
I created the VS solution using an MPC file, as below:-

project(MyLibrary) {
staticname =
sharedname = MyLibrary

includes += $(BLD)
includes += $(ACE_ROOT)
includes += $(ACE_ROOT)/TAO

libpaths += $(ACE_ROOT)/lib
lit_libs += TAO_CosNaming TAO_PortableServer TAO_AnyTypeCode TAO ACE

Source_files {
*.cpp
}

Note that the MPC above does not containing anything telling it how to
compile the IDL. I do that by hand and then run MPC. The IDL compile
line I use is:
tao_idl -I . -hc C.h -hs S.h -cs C.cpp -ss S.cpp -aw -o . <filename>

SAMPLE FIX/WORKAROUND:
None that I am aware of.

I have just found a workaround. I was curious that the problem only occurs in debug mode, then I saw this in config-win32-common.h:

#if !defined(_DEBUG)
// If we are making a release, and the user has not specified
// inline directives, we will default to inline
# if ! defined (__ACE_INLINE__)
# define __ACE_INLINE__ 1
# endif /* __ACE_INLINE__ */
#endif

Adding macros +=__ACE_INLINE__=1 to my MPC file made the problem go away.

Please note that IMHO this is a workaround and the problem still needs to be addressed.

[Adam Mitz]

Hi Andrew,

This is by design. The application needs to be built with the same
inline setting used to build ACE. If the application uses MPC, the
provided base projects, and <ace/config.h>, it should work automatically.
