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').
