Compiler Error Messages

FreeBASIC

During the program compilation three types of errors can arise:

Compiler Warnings:

The warnings don't stop the compilation, just alert the user some non-recommended and error-prone operation is attempted in the code.
Sometimes one of these operations is coded deliberately to achieve a result, in this case the warnings can be disabled by setting the -w 1 option at the command line.

1 Passing scalar as pointer
2 Passing pointer to scalar
3 Passing different pointer types
4 Suspicious pointer assignment
5 Implicit conversion
6 Cannot export symbol without -export option
7 Identifier's name too big, truncated
8 Literal number too big, truncated
9 Literal string too big, truncated
10 UDT with pointer or var-len string fields
11 Implicit variable allocation
12 Missing closing quote in literal string
13 Function result was not explicitly set
14 Branch crossing local variable definition
15 No explicit BYREF or BYVAL
16 Possible escape sequence found in
17 The type length is too large, consider passing BYREF
18 The length of the parameters list is too large, consider passing UDT's BYREF
19 The ANY initializer has no effect on UDT's with default constructors
20 Object files or libraries with mixed multithreading (-mt) options
21 Object files or libraries with mixed language (-lang) options
22 Deleting ANY pointers is undefined
23 Array too large for stack, consider making it var-len or SHARED
24 Variable too large for stack, consider making it SHARED
25 Overflow in constant conversion
26 Variable following NEXT is meaningless
27 Cast to non-pointer
28 Return method mismatch
29 Passing Pointer
30 Command line option overrides directive
31 Directive ignored after first pass
32 'IF' statement found directly after multi-line 'ELSE'
33 Shift value greater than or equal to number of bits in data type
34 '=' parsed as equality operator in function argument, not assignment to BYREF function result
35 Mixing signed/unsigned operands
36 Mismatching parameter initializer
37
38 Mixing operand data types may have undefined results
39 Redefinition of intrinsic

Compiler Error messages:

The error messages stop the compilation after 10 errors (see the -maxerr command-line option to change that default value) or a fatal error occurred, and require a correction by the user before the compilation can be continued. The compiler signals the lines where the errors have been found, so the correction can be done quickly. In a few cases the place pointed at by the error messages is not where the errors can be found, it's the place where the compiler has given up in waiting for something that should be somewhere.

Third party programs errors

These errors occur after the source has been compiled into assembler, they come from the auxiliary programs FB requires to compile a source into an executable: the linker, the assembler and (for Windows programs) the resource compiler.

If an IDE or a make utility are been used, additional errors can arise. These errors are outside the scope of this help.
