error C2143

Yes, but I don't know if I can, because from step
TestAndClearDirty(ni);totest_and_clear(ni, Name), the second paramter is missing (see the first post). Moreover, atstep test_and_clear_bit(NI_##flag, (ni)->state)what is the first parameter ? -
That is exactly the problem. We do not have that information and you are not providing it.
Believe me, I haven't extra information, for instance, at step
test_and_clear(ni, Name), when I try to go to definition ofName, VS editor goes nowhere, searched globally in the whole project, found nothing, and searched in the entire project folder with the external file seeker, found no defintion of thisNameparameter ... -

Namerefers to something outside of the definition:#define TestAndClearDirty(ni) \
test_and_clear(ni, Name)But if
Namedoes not exist in that source module, or is not externalised in a linked module it will never work. My suspicion is that this macro is wrong andNameshould be one of the formal parameters, and refer to one of the flags in the ni struct. Something like:#define TestAndClearDirty(ni, Name) \
test_and_clear(ni, Name)And it would be called by
TestAndClearDirty(ni, some_falg_name);
But I am working completely in the dark and making (probably wild) guesses. I can only suggest that you go back to the place or person that this code comes from for assistance.

I have discovered something: if I write:
TestAndClearDirty(ni);
everything is ok. But if I write:
BOOL b = TestAndClearDirty(ni); // <-- errors
I get errors:
error C2552: 'b' : non-aggregates cannot be initialized with initializer list
error C2143: syntax error : missing '}' before 'const'
error C2143: syntax error : missing ';' before 'const'
error C2143: syntax error : missing ';' before 'const'
error C2065: 'old_state' : undeclared identifierSee first post for original definition ... I hope I can make it ... P.S. Why I written BOOL b = ... ? Because that function,
TestAndClearDirty, is used inside some if condition ... -
I come back for another strange error (for me is strange :) ):
error C2143: syntax error : missing ')' before '{'
And the lin with error is:
TestAndClearDirty(ni); // <-- error C2143: syntax error : missing ')' before '{'
and
TestAndClearDirtyis declared as:#define TestAndClearDirty(ni) \
test_and_clear(ni, Name)where
test_and_clear(ni, Name)is defined as:#define test_and_clear(ni, flag) \
test_and_clear_bit(NI_##flag, (ni)->state)and
clear_bitis declared as:#define test_and_clear_bit(bit, var) \
({ \
const BOOL old_state = test_bit(bit, var); \
clear_bit(bit, var); \
old_state; \
})How to get rid of this error ?
When you have so many nested macros, one thing to do is look at a pre-processed version of the code. In MSVC, adding /P to the command line will create a file with a .i extension, containing the pre-processed code. Examining that will probably give you the cause of the error. EDIT: I see someone beat me to giving the same advice.

I have put that option on property page settings and show me no more details: The error occur in some inode.cpp file (ex C file), and those macros are some support.h file. So, when I compiled with /P option, I got only inode.i file, where I have a line:
#line 1 "d:\\project\\.......\\inode.cpp"
that is all. And support.i doesn't generated, due to error:
fatal error C1083: Cannot open include file: 'stdafx.h': No such file or directory
...

...The problem is the code is trying to use TestAndClearDirty(ni); for returning BOOL value, and I don't think that macro is written to return a BOOL value ... I guess from here is coming these errors ...
