Cross compiling Berkeley DB for ARM and MIPS

Orange Pi Development Boards

Following my blog entry about Databases for Linux Embedded Systems, here are the instructions to cross-compile Oracle Berkeley DB.

First download the source code of the latest version of Berkeley DB (version 11gR2 – 11.2.5.1.25). You’ll need to register on Oracle website first on the download page http://www.oracle.com/technetwork/database/berkeleydb/downloads/index.html to download http://download.oracle.com/otn/berkeley-db/db-5.1.25.tar.gz (with AES encryption) or  http://download.oracle.com/otn/berkeley-db/db-5.1.25.NC.tar.gz (if you don’t need encryption).

Extract the source code:

tar xzvf ../Downloads/db-5.1.25.tar.gz

Configure and build the source code. I’ll use mipsel-linux-gcc, but any other cross-compiler could be used.

cd db-5.1.25/build_unix
../dist/configure –host=mipsel-linux CC=mipsel-linux-gcc RANLIB=mipsel-linux-ranlib STRIP=mipsel-linux-strip AR=mipsel-linux-ar –prefix=/home/jaufranc/edev/lib/db-11g
make
make install

The full berkeley DB package is 79MB:

[email protected]:~/edev/lib/db-11g$ du –max-depth=1 -h
6.6M    ./lib
308K    ./bin
72M    ./docs
176K    ./include
79M    .

However, you won’t need the include and docs directory in your embedded target. So you do not need to copy those. You may or may need the utilities in the bin file. The lib diirectory contains two versions of the static library (why?) and one dynamic library  libdb-5.1.so (1.8MB).

Using CFLAGS=”-Os” at the configure step above will slightly decrease the size of the library (1.7MB).

For further size reduction, add –enable-smallbuild (equivalent to –disable-cryptography, –disable-hash, –disable-queue, –disable-replication, and –disable-verify) in the configure script as follows:

../dist/configure –host=mipsel-linux CC=mipsel-linux-gcc RANLIB=mipsel-linux-ranlib STRIP=mipsel-linux-strip AR=mipsel-linux-ar –enable-smallbuild –prefix=/home/jaufranc/edev/lib/db-11g CFLAGS=”-Os”

The size of the dynamic library (libdb-5.1.so) is decrease to 938KB and the bin directory to 288KB.

1. ../dist/configure –host=mips-linux –prefix=/home/kexf/bdb/bulid/mips.5.2/ –with-mutex=MIPS/gcc-assembly
2. make
./libtool –mode=compile mips-linux-cc -c -I. -I../src -D_GNU_SOURCE -D_REENTRANT -O3 ../src/mutex/mut_tas.c
libtool: compile: mips-linux-cc -c -I. -I../src -D_GNU_SOURCE -D_REENTRANT -O3 ../src/mutex/mut_tas.c -fPIC -DPIC -o .libs/mut_tas.o
/tmp/ccD53pYU.s: Assembler messages:
/tmp/ccD53pYU.s:102: Error: opcode not supported on this processor: mips1 (mips1) `sync ‘
make: *** [mut_tas.lo] Error 1

can you help me?

I use another toolchain but also have the error.
And, using arm and x86 are ok.

I add “.set mips2” before “sync”.
