I’m working on a DLL that’ll export some functions. I tried this with File->New->Projects->Win32 Dynamic-Link Library, and then selected the radio button 'A DLL that exports some symbols'. When I try to compile the project (as it is with the default code inserted by VC++), I get these errors:
d:\program files\microsoft visual studio\vc98\include\excpt.h(36) : error C2144: syntax error : missing ';' before type 'int'
d:\program files\microsoft visual studio\vc98\include\excpt.h(36) : error C2501: 'i' : missing storage-class or type specifiers
d:\program files\microsoft visual studio\vc98\include\excpt.h(36) : fatal error C1004: unexpected end of file found
Apparently, the offending line for all the above errors is 'extern "C" {' ( !)
Next I tried this with 'An empty DLL project', used '__declspec(dllexport)' for the functions; the errors persist.
I just tried commenting out the code line by line, figures that the compilation goes through the moment I comment out '#include<windows.h>'! I need that header file, however.
I trawled on the Web for more info on doing away with these errors, but that didn't help. What am I missing here
Thanks in advance.
excpt.h error

I had the same problems, and due to some tiping i destryoed some MFC header files. I took me 5 hours to find it. After that I always the the include files or source files in the folders for VS to read only.
Or I restrict the access to the user who is programming to just readonly to the VS folders.

I took your suggestion of checking my header files (windows.h and excpt.h) against those on my colleague's system and you're absolutely right! I found an unsuspecting 'i' on the first line of windows.h! I've no idea what that is and how it got there, but I deleted it and built my dll's and voila, got it this time round!
Thanks, thanks, thanks.

In example a missing ; behind the class definition or similar
Or is there any macro definition to the keyword extern

1) In fact, VC++ includes windows.h and not excpt.h on selecting 'A DLL that exports some symbols' and there are just some #define's above the inclusion. The line just above it is:
// Insert your headers here
#define WIN32_LEAN_AND_MEAN // Exclude rarely-used stuff from Windows headers
2) In the 'Empty DLL Project' that I selected, I'd moved #include<windows.h> to the first line, but that too didn't work.
In both of the above cases, the errors are exactly the same. Here's the code snippet from excpt.h
/*1*/ #ifdef __cplusplus
/*2*/ extern "C" {
/*3*/ #endif
The compiler flags line 2 as an error.

Can it be that one of your windows include files is destroyed or manipulated
