I gather it is a fork of an early TOAD code base, which is Oracle specific.
I have been using it at work for some time, and configured a windows 
build environment in a vm earlier this year (since been deleted for 
reasons unrelated to TOra).
I am hoping that a linux based cross compile configuration can be 
established because the requirements for the windows compilation setup 
is quite large.
It currently compiles and runs fine as an ELF binary.

I have done that as well, with the same result.

I just checked, mxe does not have a libloki-dev.
TOra cmake file fails unless I point cmake at the installed header and 
include for the external setup.
I have been assuming the internal one is out of date :)

As part of the container I create, qt5 is built with mxe, however I 
still need to point cmake to the result, otherwise it does not work.

Thanks for the information, I will look into it.

Also, in CMakeLists.txt I had to change
SET(CMAKE_CXX_FLAGS_DEBUG "-O0 -fno-inline -rdynamic")
to
SET(CMAKE_CXX_FLAGS_DEBUG "-O0 -fno-inline ")
But then I ran into this problem.
However, I gather the rdynamic flag outputs functions as they are 
called, which is presumably why it is included for Debug releases.
