Fixed that problem. Then I got this:
/usr/bin/ld: cannot find -lsqlite3
collect2: ld returned 1 exit status
make[1]: *** [BASIC256] Error 1
make[1]: Leaving directory `/home/jardogbox/basic256_1.0.0.7'
make: *** [debug] Error 2
COMPILING.txt needs to be updated and
mention that sqlite3 is required as well.
Installed sqlite3 so now I get this:
tmp/obj/Interpreter.o: In function `Interpreter::execByteCode()':
/home/jardogbox/basic256_1.0.0.7/Interpreter.cpp:5232: undefined reference to `QSqlDatabase::~QSqlDatabase()'
collect2: ld returned 1 exit status
make[1]: *** [BASIC256] Error 1
make[1]: Leaving directory `/home/jardogbox/basic256_1.0.0.7'
make: *** [debug] Error 2
A whole big string of undefined ref to QSqlDatabase happens.
