I am trying to follow and convert [this][1] Googletest tutorial to work in windows and use Make for building. I am also trying to add a more typical directory structure.

When I run this I get the following error:

make: *** [makefile:19: obj/tests.o] Error 1
The way I thought this would run would be for Make to see the Rule for runTests requires tests.o, which does not exist, then drop down and use the Rule for creating that object file. After that, return to the Rule for runTests and complete.
The output looks like Make is combining the two rules together into some kind of amalgamation with -c and .cpp files combined. Which I believe is causing this error to occur.
I am confused as to why Make is doing this.
Check this:
GTEST=D:\myWorkspace\Gtest\googletest-release-1.11.0\googletest\include\
LIBGTEST=D:\myWorkspace\Gtest\googletest-release-1.11.0\lib\libgtest.a
By having a backslash at the end of the GTEST variable assignment you've continued that line to the next line, so GTEST contains the variable assignment on the next line as well (and LIBGTEST is not set).
You've basically written this:
GTEST=D:\myWorkspace\Gtest\googletest-release-1.11.0\googletest\include LIBGTEST=D:\myWorkspace\Gtest\googletest-release-1.11.0\lib\libgtest.a
You should not, in general, use backslashes in makefiles. You should use forward slashes for directory separators.
If you do want to use backslashes at the least you should not add them at the end of variable assignments.
In MSYS2, I tried to intall a Chicken egg with::

It looks like this is a bug in the mathh egg. I've asked its author to take a look and he's published a new version. Can you try again?
from http://www.davidegrayson.com/windev/msys2/ it appears the MSYS2 -mwin32 gcc option is needed to define _WIN32. mathh uses defined(_WIN32) to trigger expansion of the q&d implementations of log2, etc. for windows.
the mathh egg mathh.setup file can be modified to supply compile-options. see the definition of mathh-compile-options in mathh.setup.
ex: (define mathh-compile-options '(-local -no-procedure-checks -mwin32))
I've just released http-client version 0.16 where I ripped out the overly complex md5 dependency, and replaced it with the new simple-md5 egg.
This should be much easier to install. It should appear on the egg mirrors shortly.

make: *** [inet] Error 2
I am using an up to date Ubuntu 16.04 LTS, compiling with cmake 3.9.6, building Veins and Vanetza worked without issue. Omnet++ Version is 5.2. The code lines, the Error is referring to are:
203 namespace inet {
204
205 Define_Module(RoutingTableRecorder);
206
207 #define LL INT64_PRINTF_FORMAT // for eventnumber_t
However expecting a ")" before line 207 makes no sense to me.
Also, this Error did not appear when building Artery on a different System (Same OS) a few weeks earlier. Using an earlier revision of the source had no effect either.
You are using OMNeT++ 5.2.
This seems to be the problem because the API has changed slightly.
INT64_PRINTF_FORMAT isn't available anymore in OMNeT++ 5.2.
Changing back to OMNeT++ Version 5.1 should resolve your error!
fprintf(routingLogFile, "%s %" LL "d %s %d %s %s %d %s\n",
^
inet/networklayer/ipv4/RoutingTableRecorder.cc:332:13: warning: spurious trailing ‘%’ in format [-Wformat=]
);
This is just a simple syntax error. Go through the path Inet/src/inet/networlayer/ipv4/ and open the RoutingTableRecord.cc file and edit at "fprintf(routingLogFile, "%s %" LL "d %s %d %s %s %d %s\n", " line and remove LL including the double quotes that is around the LL. There are two of them with in this C code. So make sure they are both corrected like the following line: fprintf(routingLogFile, "%s %d %s %d %s %s %d %s\n", .
You might also need to comment out #define LL INT64_PRINTF_FORMAT // for eventnumber_t at line number around 270.
Then save and Clean only the inet project. Then Build also only the inet project.
I am a newbie in CUDA and want to compile my first programms on a Jetson TK1.
I have searched the Internet and also this Site but dont found something, that was helpful for me.
I have found this example
http://bikulov.org/blog/2013/12/24/example-of-cmake-file-for-cuda-plus-cpp-code/
and tried to compile the CUDA example oceanFFT which runs with the sample Makefile.
http://developer.download.nvidia.com/compute/cuda/1.1-Beta/x86_website/samples.html#oceanFFT
I have changed this CMakeLists.txt a little bit, but I dont know if I did this correct.

so, not linked to this Libraries.
What did I wrong?
My problem with the sample Makefiles is, that they are to complicate for my.
I have also tried to make the sample Makefile easier.

Is their anything else, I can make easier or shorter?
I have less experience in creating makefiles and looking for a general way to create some for CUDA. I hope you can help me.

I am trying to link a static library while creating my program executable using the below makefile..
IDIR =../inc
CC=g++ -g
CFLAGS=-I$(IDIR)
WFLAGS=-Wall -W
OFLAGS=-O3
DLINUX=-D_LINUX
ODIR=obj
LDIR =../lib
LIBS=-lm
_OBJ = testclient.o
OBJ = $(patsubst %,$(ODIR)/%,$(_OBJ))

$(ODIR)/file2.o: file2.c

testclient: $(OBJ)
$(CC) -o $# $^ $(LIBS) -lccn -pthread
.PHONY: clean
clean:
rm -f $(ODIR)/*.o *~ core $(INCDIR)/*~
I have tried everything available from changing the order of the '-lccn' parameter to checking whether the function exists in the library (nm libccn.a gives the required function ccn_create() in it). The error returned is :
obj/testclient.o: In function `main':
/root/testClient/src/testclient.c:91: undefined reference to `ccn_create()'
The library libccn.a is in /usr/local/lib. I have also tried changing the directory path and then using -L flag to look in that location. Doesn't work either. :( ..Any ideas as to how can i make it work ?
My guess is that libccn.a is a C library and the header that you use are not designed to be imported by a C++ compiler (there is no extern "C" { } block surrounding the function definition).
C++ supports function overloading by mangling name of function. When you put a function in a extern "C" { } block, C++ disable name mangling (and thus disable overloading). Here, in your error message, the function mentioned is ccn_create(). Notice the (), this means that the function type is known, and thus the named looked up was a mangled name.
When you do nm libccn.a you see the real name, and it is ccn_create. That is not a mangled name. So to fix this, you'll need to surround the function definition in a export "C" { } block. The easiest way to do that is to surround the #include in such a block.
BTW, you can reproduce the error by doing this.
$ echo 'void ccn_create();' > ccn.h
$ echo '#include "ccn.h"
void ccn_create() { }' > ccn.c
$ echo '#include "ccn.h"
int main () {
ccn_create();
return 0;
}' > main.cc
$ gcc -o ccn.o -c ccn.c
$ g++ -o main main.cc ccn.o
