[Clam-devel] Re: Windows native compilation

[David García Garzón]

I should have "used the code, luke". Id3 just uses this macro in visual, in 
any other compiler it just ignores it. So I definitely removed the 
LINKOPTIONS lines.

The bad news is that this is not the problem you have. So, my second guess has 
adquired relevance: we are compiling as it were C++ (with g++) and linking as 
it were C (with gcc). The puzzling fact is that crosscompilation works 
without problems. So we need to know which is the test is failing. The pasted 
config.log, is missing the lines that say that. That information is given by 
the console output (checking id3 header/compiling/linking/runnig, id3 
header/compiling/linking/run failed) or maybe some lines above in the 
config.log. Could you paste the full config.log or attaching it to the list?

As you can see adding support to a 'new' platform is somewhat tedious and 
sloow. This is why i wanted it solved as soon as we can and then enjoy 
coding.
