+ With GNU-GCC:
+ gcc -O -g3 -Wall -D_REENTRANT -shared -o mycallback.so callbacks-example.c -lhttrack1
+ With MS-Visual C++:
+ cl -LD -nologo -W3 -Zi -Zp4 -DWIN32 -Fe"mycallback.dll" callbacks-example.c libhttrack1.lib
+
+ Note: the httrack library linker option is only necessary when using libhttrack's functions inside the callback
+
+ How to use:
+ httrack --wrapper mycallback ..
