libtasn1 not found, but I have already install it

Question

When I configure gnutls and p11-kit, it show that "libtasn1 not found", but i have already install it. why and how to solve it?

Answer 1

If you want to link a shared library in some executable you are building, not just make that library available to programs at runtime, then you need to have installed its header files as well as the library itself, so that the compiler can find them.

Therefore, when ./configure checks for a library that you need to link, it checks if you have the library headers as well as the library.

To get the library headers, you need to install the development package of the library, not just the runtime package.

If you are using a debian-based distro, then the development package for libtasn1 is libtasn1-N-dev (for some number N). For RPM-based distros it will be something on the lines of libtasn1-devel-X.Y-Z....
