Boostc Linker: Failure If Extern Not Defined

Recommended Posts

Bug description:

The BoostC linker fails with "No Error" if you declare an extern variable, but never define it.


Steps to reproduce:

1.) Create a new project

2.) Add a main.c file to the project with the following code

extern char x;

void interrupt()

void main()

3.) Compile the project using BoostC

4.) Notice the linker error message.


Expected behavior:

The linker should allow an undefined extern variable (as long as it is not used).

MSVC++ allows an undefind extern.


Is the problem 100% reproducible:



PicAntIDE version: PicAndIDE version

Compiler: BoostC

Compiler version: 1.1 Alpha


OS: Windows XP
