"Core dumped" in 'async' mode

[mrayva]

For every example query, compiled into c++ ( options -F -O3 -F -COMPILE-WITH-STATIC )

"terminate called after throwing an instance of 'std::system_error'
what(): Unknown error -1
Aborted (core dumped)"

Please clarify: 1) which DBT release (linux, macos, win) is used; 2) which commands are used to generate code and compile.

Ubuntu 16.04 SCALA VERSION 2.10.7 SBT VERSION 1.1.1 gcc 5.4.0 20160609

Ok, so you're using the master branch of the backend. I assume you also set up the connection with the DBToaster frontend.

I cannot reproduce this problem on my machine (macOS); most likely the DBToaster runtime library (ddbtoaster/srccpp/lib/libdbtoaster.a) on your machine is compiled with a different version of gcc. Try running "make -C ddbtoaster/srccpp/lib clean; make -C ddbtoaster/srccpp/lib".

Also, DBToaster generates trigger functions (e.g., in bin/rs_example1.hpp). You can link that code with your application if preferred, no need to use the provided runtime library.

This is more or less how I build it under Ubuntu (a complete version attached)

The provided script (with some minor syntax modifications) generates and runs C++ programs without any problems in a similar Linux environment. The only difference is the version of g++ -- try upgrading to 6.x or 7.x. The generated C++ code uses inlining directives, which I remember were buggy in 5.4.0.
