pkg-config - the goodness



Seems like pkg-config is great tool when we're working with c/c++ codes. Normally we will use

pkg-config vips-cpp --cflags --libs

-pthread -I/usr/local/include -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -L/usr/local/lib -lvips-cpp -lvips -lgobject-2.0 -lglib-2.0


To generate list of flags for compilation. This makes life for developer so much easier. It is very time consuming to get the include and object file linked up.

Next, up is the, which show us list of package installed.


 pkg-config --list-all


This list allows us to plug into code above to generate compilation flags for other libraries.

The specified initialization vector (IV) does not match the block size for this algorithm

If you're getting  exception when trying to assigned key to a symmetric key and getting error message below :- The specified initialization vector (IV) does not match the block size for this algorithm And your code probably look like something below :- Then you need to go into debug mode and start looking into the supported size for IV as shown in diagram below :- As you can see, IV is 16 bytes, so you need to provide 16 bytes. The same goes for Key field too, if you're adding anything to it. As long as you provide a valid key size, then we're good and you're code will be ready.
