Here's the error for the mcrypt module
checking mcrypt.h usability... no
checking mcrypt.h presence... no
checking for mcrypt.h ... no
configure: error: Header file<mcrypt.h> not found.
Same error for a package called gdbm.
I'm new to Linux and am running Debian 10.2.0-amd64 with Oracle VirtualBox. I'm trying to install Scheme to use with Structure and Interpretation of Computer Programs. I know that a (.h) file is a header file and that's about it. Any ideas?
I currently don't have access to any debian machines, but given Ubuntu's similarities try:
apt-get install libmcrypt-dev libgdbm-dev
