MySQL Connect/C++ 64 bit build error - c++

I am using Netbeans and MacoSX and installed 64bit connector. On building I am getting following errors:

In Netbeans I am linking libmysqlcppconn.dylib only.
What files am I missing?
Why is it asking for BOOST? and which Boost Libs do I need to install?

mysql_connection.h includes #include <boost/shared_ptr.hpp>, you could either use latest versions of boost or modify below lines mysql_connection.h to use std::shared_ptr instead:
update
#include <boost/shared_ptr.hpp>
boost::shared_ptr< NativeAPI::NativeConnectionWrapper > proxy;
to
#include <memory>
std::shared_ptr< NativeAPI::NativeConnectionWrapper > proxy;

Have you read the documentation entitled "21.4.2. Installing MySQL Connector/C++ from Source"? Read the entire page carefully, then look for links specific to MacOSX...

How to setup CMake to build code which contains path-includes like #include <libdir/lib>?

I am trying to migrate an old C/C++ sunstudio project to visual studio 2019. I need to build targets on a remote linux machine, so I cannot use the visual studio solution to build. After some unsuccessful attempts to use the old sunstudio makefiles, I have decided to use cmake to build the project.
The problem is that the code references includes with relative paths, like this:
(tkamain.cxx):
#include <ukernel/inc/U.h>
#include <monitor/inc/monitor.h>
I don't want to touch the code, so how can I setup CMake to build this project properly with these specific include statements?
The project structure looks like this.
tka
|-mod
||-monitor
||'-inc
||-feedutils
||'-inc
|'-ukernel
| '-inc
|-inc
||-foo.hxx
|'-bar.hxx
|-src
||-foo.cxx
||-bar.cxx
||-tkamain.cxx
|'-CMakeLists.txt (CMakeB)
'-CMakeLists.txt (CMakeA)
The CMakeLists.txt are newly created by me and are probably not correctly set up yet.
The CMakeA file contains this:
project(tka)
add_subdirectory(src)
The CMakeB file contains this:
include_directories(${PROJECT_SOURCE_DIR}/inc)
include_directories(${PROJECT_SOURCE_DIR}/mod)
add_executable(tkamain tkamain.cxx)
The commands in CMakeB seem not to be sufficient for my purposes, what am I missing? Or do I need more CMakeLists.txt files?
The errors I am getting look like this:

I have tried to give more specific include paths, like this, but that didn't help either:

include_directories(${PROJECT_SOURCE_DIR}/mod/monitor/inc)

condition variables c++ windows

I am trying to run some code copied from Windows Dev Center, but keep encountering an error over some unresolved identifiers. This maybe sound silly, but why would these lines cause this error:
CONDITION_VARIABLE BufferNotEmpty;
CONDITION_VARIABLE BufferNotFull;
And "not declared in this scope" on other lines similar to this:
SleepConditionVariableCS (&BufferNotFull, &BufferLock, INFINITE);
When I've included all the headers (or at least i think) necessary?
#include <mutex>
#include <condition_variable>
#include <cstdint>
#include <windows.h>
#include <stdlib.h>
#include <stdio.h>
#include <WinBase.h>
Running NetBeans with project configured to C++11 in case that changes anything. Thanks in advance if anyone has any suggestions!

What happens if you add
#include <SDKDDKVer.h>
Before the #include <windows.h>?
The CONDITION_VARIABLE definition should be brought in by <windows.h>, but only if building against Vista-or-newer. <sdkddkver.h> should ensure you're always building against the newest target supported by the SDK.
If that doesn't help, or if <sdkddkver.h> isn't found, then it means that your build environment is using a very old, very stale SDK. I don't know what NetBeans/mingw uses for its Windows SDK, so it's quite plausible that they use a stale version.
If this proves to be the case then I think your best option would be to use Visual Studio 2015 or 2017 Community Edition along with the current Windows 10 SDK.

I'm sorry for making a question so simple but I just don't find any answer for this.
Thanks a lot, any help would be greatly appreciated!
There are two things you need to do to make this work:
use the CUDA compiler driver nvcc to steer compilation of the code
rename hellowordcuda.cpp to hellowordcuda.cu when passing the code to nvcc
The second point is necessary because nvcc uses the file extension to steer compilation, and if you code has a .cc or .cpp file extension, it will just pass the code to the host compiler and the same compilation errors will result
In guide also below lines are mentioned,
$ nvcc hello.cu
$ a.out
Hello World!
Please change g++ to nvcc in your Makefile.
It appears you're building directly with g++. You need to use NVidia's compiler (nvcc) to use CUDA, and make sure it knows to process the file as CUDA C. This can be achieved by changing the extension to .cu, or by playing around with compilation options which specify the file & processing type. I recommend the former.

Compiling fbexport under FreeBSD 10

But cd /tmp/fbexport-1.90 && make generate error:

How can I understand these dreadful errors when building gcc-4.8.2?

I am trying to install the gcc-4.8.2 compiler on a remote Debian 7 system, to which I have no root privileges, but only a ssh access. I figured out that the simplest way would be to compile the compiler from source.
I am following this short installation manual from the GCC webpage.
Basically I did the most simple installation, which is summarized at the bottom of the page:
tar xzf gcc-4.8.2.tar.gz
cd gcc-4.8.2
./contrib/download_prerequisites
cd ..
mkdir objdir
cd objdir

with the small exception that I did not run the ./contrib/download_prerequisites script on the remote machine because of firewall restrictions. Instead I ran it on my local machine, then compressed the entire folder back into gcc-4.8.2.tar.gz and scp'd it to the remote machine. There I re-created the symbolic links to the prerequisite libraries (gmp,...) and ran make. After several seconds I receive incredible errors:

I am compiling with gcc 4.7.2-5 on Debian.
On the local machine there is Ubuntu 13.10 with gcc 4.7.3 and the build seems fine so far (still running).
Please, what could be the cause of these errors?
EDIT:
I checked the /home/mdrozdik/gccbuild/libcpp/config.log file. It is very longm but in two places there are these errors:
configure:3086: gcc -V >&5
gcc: error: unrecognized command line option '-V'
gcc: fatal error: no input files
compilation terminated.
configure:3097: $? = 4
configure:3086: gcc -qversion >&5
gcc: error: unrecognized command line option '-qversion'
gcc: fatal error: no input files
compilation terminated.
configure:3097: $? = 4
But the log continues for several pages nevertheless.
I had a similar problem (gcc 4.8.3) and this solved it: g++ 4.7.1 compilation error : conflicting types for ‘strsignal’
The solution was to unset a bunch of C compiler flags (CPATH, etc.)
https://stackoverflow.com/users/1224886/tsbertalan reported this worked for him (and it's what I used):
unset LIBRARY_PATH CPATH C_INCLUDE_PATH PKG_CONFIG_PATH CPLUS_INCLUDE_PATH INCLUDE
