I a m getting some undefined references with the linking of static and dynamic libraries.
My goal is to get an executable with poco and uiohook libraries statically linked. In order to specify the static linking, I provide the direct path to the library, some as path/libName.a.
The following command:
/home/lrleon/LLVM-3.7/bin/clang -o collector -g -O2 -fno-strict-aliasing \
collector.o common-vars.o collector-events.o listeners.o \
active_window.o ../lib/libperfq-common.a \
/home/lrleon/aleph-w/libAleph.a /home/lrleon/poco/lib/libPocoNet.a \
/home/lrleon/poco/lib/libPocoFoundation.a /home/lrleon/uiohook/lib/libuiohook.a \
-lstdc++ -lX11 -lcairo -lgsl -lgslcblas -lpthread -lc
Gives me the following errors:

clang: error: linker command failed with exit code 1 (use -v to see invocation)
I do not understand why some symbols are not found. For example, ceil, floor are referenced by poco libraries, but these symbols would belong to c standard library. As I understand, these symbols should be resoluble because the c library is linked just at the end; that is after the poco libraries. Analogously with the references to X11 symbols which I believe are referenced with libuiohook and the linking order -lX11 is given afterward
Any idea about what am I doing wrong? Thanks in advance
The floor and ceil functions are defined in the Math library and I don't see you linking with libm by using -lm flag

I am attempting to link to a number of libraries in a very rudimentary manner (without the use of any Makefile or CMakeLists.txt), using the following clang++ command:
FILAMENT_LIBS="-lassimp -lbackend -lbluegl -lbluevk -lcamutils -lfilabridge -lfilaflat -lfilagui -lfilamat -lfilamat_combined -lfilamat_lite -lfilament -lfilameshio -lgeometry -lgltfio -lgltfio_core -lgltfio_pipeline -lgltfio_resources -libl -limage -limageio -limgui -lmatdbg -lmatdbg_resources -lmath -lmeshoptimizer -lrays -lshaders -lsmol-v -lutils"
clang++-7 -L../lib/x86_64/ ${FILAMENT_LIBS} -lpthread -lc++ -ldl -lSDL2 -I./ -I../include/ -I../app/ -I${RESOURCE_DIR} -Wno-extern-c-compat -std=c++14 -pthread ../suzanne.cpp ../app/Cube.cpp ../app/FilamentApp.cpp ../app/IBL.cpp ../app/IcoSphere.cpp ../app/Image.cpp ../app/NativeWindowHelperLinux.cpp ../app/Sphere.cpp -o suzanne
However, this gives the error FilamentApp.cpp:(.text+0x4d2): undefined reference to... followed by what must be every single one of the calls to functions in the aforementioned libraries.
To give some context, I am attempting to compile one of the sample apps provided by the rendering engine Filament. When this is compiled with the source code, everything works no issues, but when I attempt to link against the precompiled versions of the libraries, I get the above error.
Additionally, when I attempt to link against the same libraries with the tester main.cpp file and accompanying Makefile as described in the Filament documentation, everything links and compiles completely fine.
I have a feeling I'm doing something obvious wrong here, specifically with the clang command I am using, but I can't for the life of me see what it is. Any help would be much appreciated!

Edit 3
The variables referred to in the above errors are stored in the files
./generated/resources/resources.h and
./generated/resources/textures.h,
in relation to the clang++ directory of execution. The header file includes for these files look like this:
#include "generated/resources/resources.h"
#include "generated/resources/textures.h"
and I have included -I./ in the clang command, so surely clang should be able to see these files?
Here is textures.h:

#define TEXTURES_H_
#include <stdint.h>
extern "C" {

Put all libraries last on the line when compiling:
clang++-7 -stdlib=libc++ -L../lib/x86_64/ -I./ -I../include/ -I../app/ -I${RESOURCE_DIR} -Wno-extern-c-compat -std=c++14 ../suzanne.cpp ../app/Cube.cpp ../app/FilamentApp.cpp ../app/IBL.cpp ../app/IcoSphere.cpp ../app/Image.cpp ../app/NativeWindowHelperLinux.cpp ../app/Sphere.cpp -o suzanne ${FILAMENT_LIBS} -lSDL2 -ldl -pthread
Also, use only -pthread (remove -lpthread). There's no need for both.
You may also want to remove -lc++ and replace it with -stdlib=libc++ (which does not need to be towards the end of the line).
What happens when linking your program is that when the linker encounters a symbol (function) that has not been encountered before, it puts it on a list of unresolved symbols. For every library it examines after that, the unresolved symbols are checked. If it encounters symbols that exists in libraries already examined, linking will fail.
The ordering of the filament libraries is also important so try:
FILAMENT_LIBS=-lfilament -lbackend -lbluegl -lbluevk -lfilabridge -lfilaflat -lutils -lgeometry -lsmol-v -libl
as stated in the documentation. Note that I removed the non-filament libraries from FILAMENT_LIBS. Put those libraries in a separate variable and place that before the FILAMENT_LIBS variable when compiling.
If SDL2 uses filament, you should put -lSDL2 before the filament libraries, otherwise, leave it where it is.
If it's still failing, you can, as a last resort, wrap the filament libraries in a library group to make it resolve the internal filament dependencies:
-Wl,--start-group $(FILAMENT_LIBS) -Wl,--end-group
This is however not what you want since it's slow, but, it's an option.
An even more desperate option would be to wrap all libraries inside the -Wl,--start-group ... -Wl,--end-group pair just to verify that it compiles and that you have all the libraries and object files needed.

Maybe it is important, the IDE don't understand
#include node.h
and I have to change it to #include node/node.h
It seems, that compiler sees only node and v8 headers and cannot find their sources.
Can somebody help me to fix that? How to make compiler to see node and v8 sources?
PS. My CmakeLists.txt file
cmake_minimum_required(VERSION 3.3)
project(test4)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES addon.cpp main.cpp myobject.cpp myobject.h)
add_executable(test4 ${SOURCE_FILES})
If you follow the README and use node-gyp with the -v flag, you can see that compilation looks like this:
g++ '-DNODE_GYP_MODULE_NAME=addon' '-D_LARGEFILE_SOURCE' '-D_FILE_OFFSET_BITS=64' '-DBUILDING_NODE_EXTENSION' -I/home/yannick/.node-gyp/5.9.0/include/node -I/home/yannick/.node-gyp/5.9.0/src -I/home/yannick/.node-gyp/5.9.0/deps/uv/include -I/home/yannick/.node-gyp/5.9.0/deps/v8/include -fPIC -pthread -Wall -Wextra -Wno-unused-parameter -m64 -O3 -ffunction-sections -fdata-sections -fno-omit-frame-pointer -fno-rtti -fno-exceptions -std=gnu++0x -MMD -MF ./Release/.deps/Release/obj.target/addon/myobject.o.d.raw -c -o Release/obj.target/addon/myobject.o ../myobject.cc
So it's a tad more complex that just specifying a few sources : there are several include dirs to be used, that seems specific to the node version you are running, and include an external dependency (libuv)
Why don't you use the build methods suggested by the README ?

It would appear these are internal linking errors? How do I go about finding the source of these errors?
you need to compile all the files and link them together. It's either missing a cpp file or library
This might be the problem. You need to use -L to specify where library files are. -I is to specify where included files are located.
g++ "-IC:\\Users\\Jesse\\Documents\\Work\\Research\\FiberTracking\\Software\\mrtrix\\source\\mrtrix-0.2.11\\lib" "-IC:\\Users\\Jesse\\Programs\\gtk+\\lib" "-IC:\\Users\\Jesse\\Programs\\gtk+\\bin" "-IC:\\Users\\Jesse\\Programs\\gtk+\\include\\glib-2.0" "-IC:\\Users\\Jesse\\Programs\\gtk+\\lib\\glib-2.0\\include" "-IC:\\gtkmm64\\include\\glibmm-2.4\\glibmm" "-IC:\\gtkmm64\\include\\glibmm-2.4" "-IC:\\gtkmm64\\lib\\glibmm-2.4\\include" "-IC:\\gtkmm64\\include\\sigc++-2.0" "-IC:\\gtkmm64\\lib\\sigc++-2.0\\include" "-IC:\\Program Files (x86)\\GnuWin32\\include" "-IC:\\Program Files (x86)\\GnuWin32\\include\\gsl" -O0 -g3 -Wall -c -fmessage-length=0 -o "src\\mrconvert.o" "..\\src\\mrconvert.cpp"
I think some of them shouldbe changed to -L. for example
"-IC:\\Users\\Jesse\...lib"
Should be
-L"C:\\Users\\Jesse\...lib"
And should go on the linkage line. i.e. The second line where you link everything.
