parse error at end of input :(

parse error at end of input :(

[Jordi Vendrell]

[-- Attachment #1: Type: text/plain, Size: 389 bytes --]

 hi,

 I'm compiling a program I have here using gcc-2.95 but I get this
 main.c:219: parse error at end of input
 error message.
 I've checked but haven't seen any parse error. Anyone sees where is
the problem?
 I'm using Knoppix distro with kernel 2.4.27

 kind regards


 Jordi Vendrell

 PS: the program is a function separated from a bigger program, but I
guess it should work anyway

Hi Jordi,

I see that the body of main has an open-curly brace, but does not have a
close-curly brace.

That will cause a parse error at end of input.

HTH,

I see that the M_PACK4 macro has an open "(".

Thanks to all, closing a brace fixed the problem.
Now the thing follows with  some messages saying

/tmp/ccsz9G07.o(.text+0x124): In function `main':
: undefined reference to `comedi_data_read'

which I guess means a problem with the libraries (comedi.h and
comedilib.h) I think it's a problem with the comedi version, so I'll
compile again and see if it works now

cheers

thats a linking problem.  It isn't finding the object file that contains the comedi_dara_read function. If that function is in a library, you probably just need to modify the -L flag so the linker can find it.

Thanks for the quick answer.
Actually I know nearly nothing about how the linker works. Could you
tell me where to start? (or else how to modify the -L flag?)

kind regards

man ld to learn about the linker.

in your case you should have a libcomedi.a (for a static library) or a libcomedi.so (for a shared library).  First, you need to tell the linker to link in one of these files by passing it -lcomedi 
(since you are most likely not invoking the linker directly, you can just pass this argument to gcc ).  Then if you get an error message stating that it cant find libcomedi, you'll need to pass a -L flag to let the linker know in what directory it can find libcomedi.a or libcomedi.so
