Re: linking a C++ lib to an objc tool.

Well that was a colossal waste of time. Interestingly, I found I cud get rid of the other dependencies, SDL1 and Freetype, as they are no longer needed by the main binary. So the ONLY requirement is poppler-cpp, so shuffling it is pointless.

Here's the contents of the make files (if it helps):

Main GNUMakefile

include $(GNUSTEP_MAKEFILES)/common.make

TOOL_NAME = WindowServer
TOOL_INSTALL_DIR = /usr/lib/GnuStep

WindowServer_OBJC_FILES = hash.m \
tree.m \
stack.m \
WSFeedback.m \
WSComponent.m \
WSModule.m \
WSModuleManager.m \
WSDisplayModule.m \
WSKeyboardModule.m \
WSPointerModule.m \
WSMiscModule.m \
WSEvent.m \
WSWindowManager.m \
WSConfigurationReader.m \
WSServerCore.m \
WSWindow.m \
main.m

WindowServer_OBJC_HEADERS = WSFeedback.h \
WSComponent.h \
WSEvent.h \
WSModule.h \
WSModuleManager.h \
WSDisplayModule.h \
WSKeyboardModule.h \
WSPointerModule.h \
WSMiscModule.h \
WSWindow.h \
WSWindowMAnager.h \
WSConfigurationReader.h \
WSServerCore.h \
Algorithm/hash.h \
Algorithm/stack.h \
Algorithm/tree.h

WindowServer_CC_FILES = rendering.cc

WindowServer_CC_HEADERS = rendering.h

SUBPROJECTS = Modules/Display \
Modules/Input \
Modules/Misc

CC=${CXX}

after-all::
    #strip obj/$(TOOL_NAME) || strip obj/$(TOOL_NAME)
    chmod 0555 obj/$(TOOL_NAME) || chmod 0555 obj/$(TOOL_NAME)

(I put the 'after-all::' rule a long time ago, not sure why I had to leave it like that, pay it no mind).

Hmm, I must admit I hadn't even thought about that. I'll give it a go
and see what happens.

It worked before adding the PDF rendering requirement (I was
concentrating on other parts of the system).

Not as of yet, hold your horses! :P
