Неопределенная ссылка на __cxa_atexit с Matlab/CUDA MEX

Я компилирую некоторые CUDA/C для запуска в качестве библиотеки MEX в Matlab, и я получаю следующую ошибку:

Error using mex
/usr/lib/x86_64-linux-gnu/libc_nonshared.a(atexit.oS): In function `atexit':
(.text+0x12): undefined reference to `__cxa_atexit'
collect2: error: ld returned 1 exit status

Я предполагаю, что это означает, что мне нужно связать какую-то дополнительную библиотеку, но что?

Моя текущая команда компиляции:

mex -L/usr/local/cuda/lib64 -lcudart -I./ A.cpp B.cpp C.cu D.cpp

У меня есть несколько ядер, которые нужно скомпилировать в mex, и что интересно, некоторые из них работают, а некоторые нет. Я не сразу вижу, в чем разница между ними - я, конечно, нигде в своем исходном коде не вызываю atexit.

Вот вывод подробного мекса:

Verbose mode is on.
Neither -compatibleArrayDims nor -largeArrayDims is selected.
     Using -compatibleArrayDims. In the future, MATLAB will require the use of
     -largeArrayDims and remove the -compatibleArrayDims option.

Мне интересно, стоит ли мне попробовать использовать другую версию g++ или библиотеки C++? Я не уверен, как изменить переменную CPPLIB_DIR... В 2014a Matlab усложнил работу с настройками mex.

Спасибо за любые мысли!
