ORBConcurrency thread-per-connection

create file hello_svc.conf with the following content according to this document:
static Resource_Factory “-ORBResources global -ORBReactorType select_mt”
static Server_Strategy_Factory “-ORBConcurrency thread-per-connection”
start naming server:
tao_cosnaming -ORBListenEndpoints iiop://localhost:9999
start servant:
taohelloserver -ORBInitRef NameService=corbaloc:iiop:localhost:9999/NameService -ORBSvcConf ~/workspace/taohelloserver/hello_svc.conf

The document says that it can also be configured by code instead of file:
TAO::ORB::default_svc_conf_entries //TAO_Internal::
(NULL, NULL, “static Server_Strategy_Factory \”-ORBConcurrency thread-per-connection\””);
but I got link error:
/home/onega/workspace/taohelloserver/Debug/../taohelloserver.cpp:21: undefined reference to `TAO::ORB::default_svc_conf_entries(char const*, char const*, char const*)’
collect2: ld returned 1 exit status

[onega@localhost Debug]$ nm –demangle $ACE_ROOT/lib/libTAO.so | grep “default_svc_conf_entries”
000efa80 t TAO::ORB::default_svc_conf_entries(char const*, char const*, char const*)

There is a post recommended adding TAO_Export to default_svc_conf_entries() in TAO_Internal.h, but I still got the link error after rebuild TAO.

IE7 compatibility issue

An application used wininet.dll works properly on system with IE6 installed, but failed to allocate 800MB memory on system with IE7 installed. The address space is fragmented by the following 2 DLLs

3d930000 3da01000   WININET  C:\WINDOWS\system32\WININET.dll

3dfd0000 3e015000   iertutil C:\WINDOWS\system32\iertutil.dll

This issue is fixed by /DELAYLOAD linker option.

MinGW and boost

On windows 7 enterprise 64bit OS
install mingw-get-inst-20111118
d:\src\boost_1_49_0>bootstrap.bat mingw
d:\src\boost_1_49_0>.\b2.exe –build-type=complete –toolset=gcc stage

when using boost library, define BOOST_THREAD_USE_LIB to fix undefined reference error as the following:
**** Build of configuration Debug for project boostprocess1 ****

**** Internal Builder is used for build ****
