I tried to install MAGE with my CLang and GCC compiler (version 11).
However, the build failed. I suspect that the reason is the fact that I didn't add
#include <cstdint> to mg_utility/mg_graph.hpp.
Which compiler should I use to compile my own Memgraph query module?

I'm trying to write some code using the boost libraries on windows 10. To build the application I have chosen mingw64, which I have installed together with MSYS2.
After downloading and installing the boost libraries(1.76), I tried this example code (https://www.boost.org/doc/libs/1_76_0/more/getting_started/windows.html#build-a-simple-program-using-boost), which I built fine using this command:
g++ .\example.cpp -o test.exe -IC:\Users\Benelli\BoostLib\boost_1_76_0\boost_1_76_0
This example works on my system so I assumed that the boost libraries are installed correctly, although I did not build them, but I understood that the boost.test libary can be used as "header only".
I written a simple code following this tutorial:https://www.boost.org/doc/libs/1_76_0/more/getting_started/windows.html#build-a-simple-program-using-boost.
#define BOOST_TEST_MODULE const_string test
#include <boost/test/unit_test.hpp>
This code does not compile and I really do not get why. Is the boost.test library really "header_only"?
The command I used to build it was:
g++ .\boost_test_example.cpp -o boost_test.exe -IC:\Users\Benelli\BoostLib\boost_1_76_0\boost_1_76_0
Which gives this error message:
For the header only:
I think you need to use boost/test/included/unit_test.hpp as per the boost docs at https://www.boost.org/doc/libs/1_69_0/libs/test/doc/html/boost_test/adv_scenarios/single_header_customizations/multiple_translation_units.html
I had a similar winMain error and had to the define for BOOST_TEST_DYN_LINK to the top of the code (when i was linking against the libraries).
#define BOOST_TEST_DYN_LINK
#define BOOST_TEST_MODULE const_string test
#include <boost/test/unit_test.hpp>
When not using the header only for the undefined references link with the boost test library, eg -LC:/msys64/mingw64/lib -lboost_unit_test_framework-mt.
I have gcc 4.8.5 installed on a Red Hat 7.5 machine.
I wish to compile a software package on this machine.
In order to compile this package, I need to run "make".
However, when I run this, I see the following error message "error: ‘make_unique’ is not a member of ‘std’".
My understanding (possibly incorrect) is that this message originates from the fact that 4.8.5 uses C++11 and "make_unique" requires C++14. So I presume the way to compile this is to specify that C++14 should be used when I run "make".
How do I do this ?
I have tried to set the C++ to 14 as follows:
cmake -G "Unix Makefiles" -D CMAKE_CXX_STANDARD=14
And then I ran "make".
But this gave the same error message.
You are using compiler that does not support C++14. As stated in the documentation:
GCC supports the original ISO C++ standard (1998) and contains experimental support for the second ISO C++ standard (2011).
It is no surprise, since GCC 4.8 was originally released in 2013 so it would be weird if it implemented a standard introduced a year later.
To use C++14 or even C++17 you can compile it with RH Devtoolset 8. The built software would run on target OS w/o any additional effort due to the "nature" of DTS compiler: the symbols available in the OS-shipped libstdc++ gonna be resolved dynamically, while C++11 and above gonna be linked to you executable from the specially built static libstdc++.a provided by DTS.
I'm working on an embedded project which will be using an arm7-a (armhf) system on a chip running Debian Jessie.
This system includes GCC/G++ 4.9.2, which should be fully C++11 compatible.
However, I'm seeing issues like, std::mutex and std::condition_variable not being present in the std namespace. I believe this is because the _GLIBCXX_HAS_GTHREADS macro isn't defined. I've found this to be the case whether I pass -std=gnu++0x or -std=c++11.
Does anybody know if this is expected behaviour on this platform?
I'm trying to compile a library on windows with mingw, that uses boost.
I compiled boost with:
bootstrap mingw
b2 toolset=gcc
After that I build the library with cmake and mingw.
Building the dll itself works fine, but when I try to build the tests, I get:
C:/boost/boost_1_55_0/boost/test/utils/runtime/config.hpp:95:51: error: 'putenv'
was not declared in this scope
putenv( const_cast<char*>( fs.str().c_str() ) );
So the error comes from a boost header and I have no idea how to fix that.
The repo of what I'm trying to build: https://github.com/linges/daestruct
It uses c99 and c++11.
This seems to be a bug in boost. It has been happened to others, too:
https://github.com/BoostGSoC/boost.afio/commit/1b06855b6e20a01a3c4461c6d2d54e16eb3c8e21
The solution (or better: workaround) is to add the following lines before the inclusion of boost::test:
#ifdef __MINGW32__
// Mingw doesn't define putenv() needed by Boost.Test
extern int putenv(char*);
#endif
I am using Boost.Regex library to write a code for 10 digit mobile no. verification.I have compiled the Boost library using bjam.exe for msvc.
Now I want to run the same code for a BREW handset.For generating the executable (mod file) for the handset, I compile the C++ code using RVDS 3.0.The IDE used is Code Warrior 5.7
Can any body please tell me the way to compile boost library for RVDS 3.0.I am using armcc compiler.
You might want to rebuild the boost libraries with the appropriate compiler set to --toolset parameter of bjam. Here is the bjam reference: Boost Jam
