xa v2.3.5中使用#include出现语法错误，求助排查原因

Hey there, let’s work through this #include syntax error you’re facing with xa v2.3.5. I’ve spent plenty of time tinkering with xa for 6500-series assembly, so let’s break down the most common pitfalls that might be tripping you up—since man pages can sometimes be a bit cryptic!

Common Causes to Check #

1. Quotation Marks vs. Angle Brackets #

Unlike C compilers, xa only recognizes double quotes for include directives. If you’re using <> like #include <myfile.inc>, that’s almost certainly the issue. xa expects the syntax to be:

#include "myfile.inc"

The man page might mention include paths but gloss over this syntax detail, which is easy to miss.

2. Missing Include Path or Incorrect File Location #

If your include file isn’t in the same directory as your main assembly file, you need to tell xa where to look with the -I flag. For example, if your includes are in a includes/ subfolder, compile with:

xa main.s -Iincludes/ -o output.bin

Without this, xa might fail to find the file and throw a misleading syntax error instead of a "file not found" message—super confusing, I know!

3. Syntax Issues in the Include File #

Sometimes the error isn’t with the #include line itself, but with invalid code inside the included file. xa will report the error as being on the #include line in your main file, even though the actual problem is in the included .inc/.s file. Try simplifying your include file to something trivial (like TEST = $40) and see if the error goes away.

4. Trailing Spaces or Syntax Typos #

Older versions of xa (like 2.3.5) are strict about whitespace in directives. Make sure there’s no extra space between #include and the quoted filename. For example:

• ❌ Wrong: #include "myfile.inc" (extra spaces)
• ✅ Correct: #include "myfile.inc"

Quick Test to Isolate the Problem #

Create two minimal files to rule out other variables:

1. test.s:

   #include "test.inc"
   lda #TEST
   

2. test.inc:

   TEST = $00
   

Compile with xa test.s -o test.bin. If this works, your original issue is likely tied to pathing or content in your actual include file. If it still errors, double-check your xa installation (maybe a corrupted binary?) or verify the exact error message to narrow things down.
