Compiling sqlite3.c in Ubuntu

SQLCipher

Hi! I’m trying to compile the generated sqlite3.c file to include it in a project, but after successfully running these commands:

./configure --enable-tempstore=yes CFLAGS="-DSQLITE_HAS_CODEC" LDFLAGS="-lcrypto"
make sqlite3.c

When I execute :

gcc -lpthreads -ldl sqlite3.c

I end up with lots of errors:

sqlite3.c:38208:42: error: ‘close’ undeclared here (not in a function); did you mean ‘clone’?

Any tips to solve this issue?
