[Geany-devel] Geany Plugin with Libxml

Hello Chow,

Thanks for your feedback :-) I've fixed the issues you mentionned (I hope)
and upgraded a little bit my code. Since now I always used my small compile
script which is very simple :



gcc -std=c99 -o "$output.o" -Wall -c -fpic "$source" `pkg-config --cflags
geany libxml-2.0`
gcc -shared  -o "$output.so" "$output.o" `pkg-config --libs geany

And so far there was no compile error. Can you explain me how to use the
automatic build so I won't commit unbuildable code ?
One more question : in my Plugin.c file, I #include the PrettyPrinter.c file
because at if I use PrettyPrinter.h, at runtime Geany said me that it was
unable to find the reference to my PrettyPrinter options... Maybe something
wrong in my compilation script ? That's a problem of linking isn't it ?

I you have any other comment, please let me know :-)

Best regards,
