Hi, I have a question about #line directive. I have two files. a.c and b.c
under my c:/ (I use Windows MinGW)
Now, I have a.c
---------------------------------------------
int main()
{
#line 1 "b.c"
int a
return 0;
}
---------------------------------------------
and b.c
---------------------------------------------
int f1()
{
return 0;
}
---------------------------------------------
Now, I try to run the command line:
C:\>gcc -c C:\a.c
b.c: In function 'main':
b.c:2:3: error: expected '=', ',', ';', 'asm' or '__attribute__' before
'return'
C:\>
You can see, the gcc report error says there are some error in "b.c" but not
"c:\b.c".
which means gcc can not dynamically resolve the file path after the #line
directive.
Though I can hard-coded the "c:/b.c" to the a.c file, but this is not a good
solution because I would always move the code to other place.
My question is: Can any one give me an idea to solve this kind of problem?
thanks.
