Re: Including C code on A4GL

You cant include a C file based on a variable - so anything based on :

 LET l_path = "/some/other/directory/my_c_file.c"

isn't going to work - the variable usage is a runtime thing - whereas
the #include is done at compile time..

There are several ways to do what you want though.

First - include the file by using the absolute file name :

{!
code
#include "/path/to/c/file/my_c_file.c"
endcode
!}


Or specify the path on the compile line using the C compilers -I
(capital i) and the path :


{!
code
#include "my_c_file.c"
endcode
!}

and then

    4glpc -o somefile.4ae somefile.4gl -I /path/to/c/file


The final way - is not to include the file at all - but just link with it..


4glpc -o somefile.4ae somefile.4gl /path/to/c/file/my_c_file.c

Get your SQL database under version control now!
Version control is standard for application code, but databases havent 
caught up. So what steps can you take to put your SQL databases under 
version control? Why should you start doing it? Read more to find out.
