Subject: [Boost-build] Jamfile setup for load on demand DLLS
From: Robert Ramey (ramey_at_[hidden])

Here is a small piece of code which is part of one of my serialization
tests:
HINSTANCE hDLL; // Handle to DLL
hDLL = LoadLibrary("dll_polymorphic_derived2.dll");
BOOST_CHECK_MESSAGE((0 != hDLL), "Failed to find/load
dll_polymorphic_derived2" );
save_exported(testfile);
load_exported(testfile);
FreeLibrary(hDLL);
This runs successfully when I test from the msvc ide where the file
"dll_polymorphic_derived2.dll"
has been placed in the same directory as the executable. So far so good.
When I update my Jamfile.v2 with
lib dll_polymorphic_derived2_lib
:
polymorphic_derived2.cpp
../build//boost_serialization
:
<link>shared
;
...
[ test-bsl-run test_dll_plugin : : dll_polymorphic_derived2_lib :
<runtime-link>shared ]
It's not clear to me where the dll is located. That is, should the
following be changed?
hDLL = LoadLibrary("dll_polymorphic_derived2.dll");
and if so to what?.
Also, I make a new version of the above code for *nix which uses dlopen,
dlclose, etc.
But again, I'm not sure what the path names should be.
Any help appreciated.
