Bug ID: 91966
Summary: LibreOffice 5 (64-bit) cannot load a UNO component
on Windows OS
Product: LibreOffice
Version: 5.0.0.0.beta1
Hardware: x86-64 (AMD64)
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: LibreOffice
Assignee: libreoffice-***@lists.freedesktop.org
Reporter: ***@gmail.com

The 64-bit version of LibreOffice 5 cannot load a UNO component on Windows OS.
LibreOffice 5 display the following message «cannot get environments». The
problem doesn’t appear on the 32 bits version of LibrerOffice 5. My code uses
«CPPU_STRINGIFY( msci )» to set the name of the environment.

How about beta3, does it still have the problem
http://dev-builds.libreoffice.org/pre-releases/win/x86_64/
It's about half way through the list,

The problem still there with LibreOffice 5.0.0.4.

Is it possible to install an extension with a UNO componant generated with C ++
code in LibreOffice 5 (64-bit)?

The problem seems to be that LibreOffice does not recognize the "MSCI"
environment.
Reference: export function component_getImplementationEnvironment

Here tested conguration
- Windows 7 (64 bits)
- Visual Studio 2013
- LibreOffice 5.0.0.4 (64 bits)

The problem is still there with LibreOffice 5.2.1.2.

testdruide's diagnostic is not quite right though. The problem is not that
LibreOffice does not recognize msci, rather that msci is not the right value.
The right value for windows_x86_64 happens to be mscx. The
CPPU_CURRENT_LANGUAGE_BINDING_NAME should the correct value at any time but in
the 64 bit sdk for Windows its value is msci instead of the correct mscx.

For the time being I have been able to fix my extensions changing the
component_getImplementationEnvironment function from this:

SAL_DLLPUBLIC_EXPORT void SAL_CALL component_getImplementationEnvironment(
const sal_Char ** ppEnvTypeName, uno_Environment ** ppEnv )
{
*ppEnvTypeName = CPPU_CURRENT_LANGUAGE_BINDING_NAME;
}

to this:

SAL_DLLPUBLIC_EXPORT void SAL_CALL component_getImplementationEnvironment(
const sal_Char ** ppEnvTypeName, uno_Environment ** ppEnv )
{
#if _WIN64
*ppEnvTypeName = "mscx";
#else
*ppEnvTypeName = CPPU_CURRENT_LANGUAGE_BINDING_NAME;
#endif
}

My guess is that simply changing the -DCPPU_ENV=msci to -DCPPU_ENV=$(CPPU_ENV)
in odk/settings/settings.mk might help

tdf#91966: In SDK, set CPPU_ENV=mscx for 64-bit Windows

If someone confirms that that (blind) fix to the SDK's settings/settings.mk
actually helps, it can be backported to 5.1.6/5.2.2.
