Hi All,
I need to use a C++ so file in FreePascal. I have written a C wrapper for it,
which successfully connected to Pascal.
Now my question is, can I use the $linklib directive to link the C-Wrapper
STATICALLY, which in-turn use the shared so file? I tried to do this but it
complained a lot of
undefined references.
This is normal.
The key problem is, the {$linklib} instruction only tell FPC where to look for
external functions in the C Wrapper, but how can I tell the linker to look for
the ORIGINAL C++
so file to look for symbols required but not defined in the C-Wrapper?
{$linklib XYZ}
can be used for any library. So you should add the C wrapper library, C++
library,
and probably some others as well, such as the C++ STL.
