Hello, as a novice in ASN.1 I have me to a project in C ++ under use of
ASN.1 - structures risquély. One of my colleagues means, this would
deal something with masochism ;-). Result should be a DLL which
provides the exchange of documents between a DMS and a remote data
base. My developing environment is MSVS v.7.1, and the ASN.1 - source
texts are generated with the compiler asn1c-0.9.20. Therefore I have in
the project cpp-, as well as c - source texts. With the left I receive
the following mistake lines:

Hi

I haven't used the asn.1 compiler myself. But looking at the messages you
seem to be missing functions to print the standard asn.1 tags like integer,
sequence etc.

I could imagine (since I guess these would be the same for any asn.1
program) there is a library around with these functions/variables. Isn't
there a .lib file around. If there is you can add it to additional
dependencies in the 'linker input' tree node of the configuration dialog.

No the visual C++ library are already there by default.

I decided to download the compiler myself (wanted to see how well it works
someday anyway).

I could compile an example and saw a few problems here is one solution.

Compile your asn1 spec with the asn.1 compiler (you of course already did
this).
Create a VC++ project.
Now open windows explorer and go to the skeletons subdir of the asn1
compiler copy all header and c files except the example decoder (forgot the
correct name but it will give an error) and copy them to your VC project
dir.
Now in the solution items tab add all the asn.1 files to your project
There is one more problem in that it will miss htonl:
Go to the properties tab of your dialog
Select linker
Select Input
Add ws2_32.lib in de additional dependecies.

There is still a problem in that they used <headerin stead of "header"
Go to the properties tab
Select C/C++
Select general
Now in additional dependecies add the directory with your VC++ source
files (i.e. this is the default directory that shows up, the one with the
copied asn.1 files).

Build...

You get 2 errors about some unix specific files I believe (maybe not) if so
put those in comment.

Build, and it should work.

Since my compile succeeded; if you see more problems just let me know. (I
didn't check if the example encoder really worked though).



=Thank you

Hello Moonlit,
the gordic node is released :-)
my mistakes:
- ws2_32.lib was not put down
- /Configuration Properties / C, C ++ / Advanced - Settings confusedly

thank you very much
