Hi,

These are the C declarations:
LIBSSH_API enum ssh_known_hosts_e ssh_session_has_known_hosts_entry(ssh_session session);
LIBSSH_API enum ssh_known_hosts_e ssh_session_get_known_hosts_entry(ssh_session session,
        struct ssh_knownhosts_entry **pentry);
LIBSSH_API enum ssh_known_hosts_e ssh_session_is_known_server(ssh_session session);

The second is failing so it seems that is expecting only one argument as the others two declarations.
Not sure why...

regards,
bruno

Hi,

On GS 3.5 with a default installation (apt-get install libssh-dev) the wrapper is generated correctly.

But on a manually compiled installation I got the error below.

Which situation could lead to this problem?

The problem is with the following declaration:

LIBSSH_API enum ssh_known_hosts_e ssh_session_get_known_hosts_entry(ssh_session session,
        struct ssh_knownhosts_entry **pentry);

The token is a coma , but is expecting a right parenthesis ). For some reason it is expecting the end of the declaration but as you can see above the declaration has 2 arguments.  So somehow it is expecting another declaration .... still researching this...

a Error occurred (error 2710), expected ')' near line 592 in file /gemstone/3rd-party-bin/

libssh-0.9.4/include/libssh.h

Another idea is to generate the wrapper in 3.5.x and then back-port it to 3.3.x.

Bruno,

Here's our advice:

I would think that  editing  CPreprocessor>>defaultSearchPaths  would be a good workaround

Keep in mind that 3.5  is using the native  preprocessor   /usr/bin/cpp

for all of the macro expansion and then reading the output of  cpp  

with our CPreprocessor code.   3.3 is trying to do all of the macro

expansion in  CPreprocessor  and that has quite a few bugs that may

be triggered by system header files in newer versions of Linux than what 3.3 

was originally tested with.

If you encounter such bugs with 3.3, you might need to run 

/usr/bin/cpp on the header files of interest and then feed the resulting

output to CPreprocessor .

Hi,

In GS 3.5 it is possible to pass paths as arguments:
CHeader>>path:searchPaths:

In GS 3.3.x that method is not present but it will have the same effect if we add our paths to:
CPreprocessor>>defaultSearchPaths
Can this be a workaround for the error below ?

Trying to generate a wrapper with:
UserGlobals at: #'LibSsh094' put: (CHeader path: '/customized/path/libssh.h').
