How to build Shallot

Question

I am trying to build Shallot. I run x64 Debian Sqeeze. It runs into compile problems I don't understand...

john@hayek:~/build/katmagic-Shallot-831de01$ make
cc  -O3 -I/usr/include -I/usr/local/include -L/usr/lib -L/usr/local/lib  -Wall -o src/math.o -c src/math.c

Answer 1

src/math.h:23:24: error: openssl/bn.h: No such file or directory
src/math.h:24:25: error: openssl/rsa.h: No such file or directory
src/math.h:25:25: error: openssl/sha.h: No such file or directory

I'm guessing you don't have OpenSSL installed, or at least not the development package that includes headers. If you do, the headers aren't in /usr/include or /usr/local/include, since that's where Shallot looks by default. You can add your own include path by running:

$ make CFLAGS=-I/path/to/openssl

On Debian, these files can be found in the libssl-dev package which you can install with apt-get or your favorite package management too.
