after using cmake on my opencv build folder, I used cmd to run mingw32-make and got the following error.

Please how do i solve this, and what is LogLevel?.
At first i was using Mingw then i ran into a "mutex" issue.So i changed to Mingw64 to solve it, the I arrived at this problem. Is there a library I'm missing cause I havent found what LogLevel is.
My macOS version is 10.14
Xcode version is 10.2
To write the plugin for clang. I just install the llvm and clang from Github with following commands.
git clone https://github.com/llvm/llvm-project.git
cd llvm-project
mkdir build
cd build
cmake -G "Unix Makefiles" -DLLVM_ENABLE_PROJECTS="clang;libcxx;libcxxabi" ../llvm
Then with clang --version, it shows:
clang version 10.0.0 (https://github.com/llvm/llvm-project.git 73f702ff192475b27039325a7428ce037771a5de)
Target: x86_64-apple-darwin18.6.0
Thread model: posix
InstalledDir: /Users/kim/GitHub/llvm-project/build/bin
Now, I just try to compile very easy Hello World program:
#include <iostream>
using namespace std;
int main() {
cout << "Hello World!" << endl;
return 0;
}
with command clang++ test.cpp -o test
But unfortunately, it can't compile with error:

I have tried adding -std=c++11, -stdlib=libc++, but there are same errors.
I was getting this error while attempting to build and debug C++ code in VSCode.
For me the answer was found here:

TLDR;
xcode was configured to use the developer tools
▶ xcode-select -p
/Applications/Xcode.app/Contents/Developer
Switching to the command line tools resolved the problem.
sudo xcode-select -s /Library/Developer/CommandLineTools
It can be compiled through

I have built an instrumented libc++ as described here. I have set the flags as the above site suggests:
MSAN_CFLAGS="-fsanitize=memory -stdlib=libc++ -L/path_to/llvm-build-msan/lib -lc++abi -I/path_to/llvm-build-msan/include -I/path_to/llvm-build-msan/include/c++/v1"
and tried to build this:
#include <string.h>
#include <stdio.h>
int main(){
char str[] = "This is a sample string";
char * pch;
printf ("Looking for the 's' character in \"%s\"...\n",str);
pch=strchr(str,'s');
}
with: clang++ ${MSAN_CFLAGS} m.cpp. I got:

I also tried to build a memory sanitized clang++ using the same method as to build libc++, but I got:

Any suggestions how to compile the above code?
Of course, clang++ m.cpp works, but in this case the executable is linked to libstdc++.
Found the solution here:
compile with uninstrumented clang with -fsanitize=memory
link with the above MSAN_CFLAGS (you can omit the include paths), adding -Wl,-rpath -Wl,/path_to/llvm-build-msan/lib/
I'm trying to compile a simple c++ file that is suppose to use the mariadbc++ connector. For some reason I ran into alot of trouble with that. I get strange error messages. I neither understand them, nor do I know how to fix them.
I did a lot of research, but either nobody else ran into these problems or I just cant find them.
I installed following packages:
mariadb-client
mariadb-client-5.5
mariadb-server
libmariadbclient18
libmysqlclient18
libmysqlcppconn7
libmysqlcppconn-dev
libmariadbclient-dev
libmariadb-dev
I'm on a x64 Ubuntu 14.04 System (well Pinguy OS, but I guess, that doesn't matter)
I tried to build following programm:
#include <my_global.h>
#include <mysql.h>
#include "mysql_driver.h"
int main(int argc, char **argv)
{
sql::mysql::MySQL_Driver *driver;
sql::Connection *con;
sql::Statement *stmt;
driver = sql::mysql::MySQL_Driver::get_mysql_driver_instance();
con = driver->connect("tcp://localhost:3306","root", "herein");
if (!con->isValid()) exit(1);
stmt = con->createStatement();
stmt->execute("use testtb");
stmt->execute("INSERT INTO Testtable(id, label) VALUES (1, 1)");
delete stmt;
delete con;
return 1;
}
And I tried this command:
g++ -lmysqlcppconn -g src/test_mariadb.cpp -o bin/test_mariadb $(mysql_config --cflags) $(mysql_config --libs)
where under in src/ my source files are and in bin/ my binaries.
And finally the Compile Errors I get:

}
A header you have included has defined preprocessor macros named min, max and test. These have then conflicted with identifiers used (e.g. for method names) in other header files you have included.
Assuming that those macros have been defined in one of these headers:
#include <my_global.h>
#include <mysql.h>
you could add #undefs before you include mysql_driver.h, e.g.:
#include <my_global.h>
#include <mysql.h>
#undef min
#undef max
#undef test
#include "mysql_driver.h"
You could also consider re-arranging the order in which you include the files, or look into what headers are defining these and see whether the definition of these macros can be disabled.
From google I can't seem to find clear answers, But I don't know what to do. I suspected there might be a problem in a larger program I was writing with the array C++11 library for g++ and wrote a test program. I am using g++ 4.8.1.
main.cpp:
#include <iostream>
#include <array>
int main()
{
std::array<int,5> vector;
return 0;
}
My test command line compile is:
g++ main.cpp -std=c++11
with errors..

And clearly from the error, there is a lot of reference to the std::array file that i have included which seems to be the source of the error. What do I do?
Thanks in advance.
EDIT: added compilation commands and g++ version.
Turns out somehow a typo made its way into OP's <array>. What should have been
template<typename _Tp, std::size_t _Nm>
struct array
{
became
template<typename _Tp, std::size_t _Nm>
struct Array
{
Causing a bazillion compiler errors as it tries to process the rest of <array>.
This is a valid C++11 program.
The error you got is most probably due to dialect selection: the C++98 mode does not provide std::array container. See the docs at http://en.cppreference.com/w/cpp/container/array
Specifically, your error comes down to the following:
main.cpp: In function 'int main()':
main.cpp:5:2: error: 'array' is not a member of 'std'
std::array<int,5> vector;
^
main.cpp:5:13: error: expected primary-expression before 'int'
std::array<int,5> vector;
^
main.cpp:5:13: error: expected ';' before 'int'
So, just add -std=c++11 to the command line and things should work.
unable to reproduce with g++ 4.8.1 at Ideone:
the error messages are consistent with not providing option -std=c++11
add that option to the command line
