To run SQLCipher specific tests, configure as described in README and run the following to execute the tests\n\n```\n$ ./configure --with-tempstore=yes --enable-fts5 CFLAGS=\"-DSQLITE_HAS_CODEC -DSQLITE_EXTRA_INIT=sqlcipher_extra_init -DSQLITE_EXTRA_SHUTDOWN=sqlcipher_extra_shutdown -DSQLCIPHER_TEST\" \\\n\tLDFLAGS=\"-lcrypto\"\n$ make fuzztest\n```\nThis shows an following error:\n\n```\n#error \"SQLCipher must be compiled with -DSQLITE_THREADSAFE=\u003c1 or 2\u003e\"\n```\n\nLet's fix this by adding -DSQLITE_THREADSAFE:\n```\n$ ./configure --with-tempstore=yes --enable-fts5 CFLAGS=\"-DSQLITE_THREADSAFE=1 -DSQLITE_HAS_CODEC -DSQLITE_EXTRA_INIT=sqlcipher_extra_init -DSQLITE_EXTRA_SHUTDOWN=sqlcipher_extra_shutdown -DSQLCIPHER_TEST\" \\\n\tLDFLAGS=\"-lcrypto\"\n$ make fuzztest\n```\nWe still have error:\n```\n#error \"SQLCipher must be compiled with -DSQLITE_THREADSAFE=\u003c1 or 2\u003e\"\n```\n\nThis is because sessionfuzz.c has following define hardcoded in the code\n```\n#define SQLITE_THREADSAFE 0\n```\n\nNow let's remove this define so that the configured flag takes effect, and running the configure produces following error: \n```\n./fuzzcheck fuzzdata1.db: SQLite has memory in use before the start of testing\n```","author":{"url":"https://github.com/IrfanMusa","@type":"Person","name":"IrfanMusa"},"datePublished":"2025-06-03T14:17:35.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/555/sqlcipher/issues/555"}
