Cross Compile SqliCipher for arm


#1

Hi,

I am trying to cross compile sqlcipher for linux based arm processor. I am using Ubuntu to cross compile.

I have cross-compiled openssl to the arm architecture and using the static library to link against.

I have set the CC environment variable to point to cross-compiler gcc

I use the following command to compile.
$./configure --host=arm --enable-static=yes --enable-tempstore=yes CFLAGS="-DSQLITE_HAS_CODEC" LDFLAGS="/path/to/libcrypto/libcrypto.a"

I get the following output from config.

Hi @onkarmahajan

checking for HMAC_Init_ex in -lcrypto… no
configure: error: Library crypto not found. Install openssl!"

The ./configure script cannot locate a system install of OpenSSL. As you are providing your own build of OpenSSL, try passing --with-crypto-lib=none to ./configure, then pass -DSQLCIPHER_CRYPTO_OPENSSL with your CFLAGS.

Hey @developernotes

Thank you. The configure script works but when I run the make command I get an error that sqlite3.c cannot find openssl/rand.h.

sqlite3.c:20258:26: fatal error: openssl/rand.h: No such file or directory

I really appreciate your help.

Thanks,
Onkar

Hi @onkarmahajan

Your CFLAGS must also include the path to your OpenSSL include folder (i.e., -I/some/path/here).


#5

Thanks @developernotes for the quick response.

For some reason, I am getting undefined references to the openssl library. I have provided a cross-compiled static library to LDFLAGS.

./configure --host=arm --enable-static=yes --with-crypto-lib=none --enable-tempstore=yes CFLAGS="-DSQLITE_HAS_CODEC -DSQLCIPHER_CRYPTO_OPENSSL -I/home/onkar/Downloads/openssl-1.0.2k/include" LDFLAGS="/home/onkar/Downloads/openssl-1.0.2k/libcrypto.a"

The linker error I get is:

./.libs/libsqlcipher.a(sqlite3.o): In function HMAC_CTX_new': sqlite3.c:(.text+0x3034): undefined reference toCRYPTO_malloc’
sqlite3.c:(.text+0x3042): undefined reference to `HMAC_CTX_init’

Thanks,
Onkar
