[Updated: 15\/03\/2013]<\/strong><\/p>\n

Recently, I needed a software that sends and recevies Short Message Services (SMS) from a Linux ARM-based embedded device. Obviously, I needed something with a small foot-print and not resource-hungry. I found three FOSS options that could fit my needs:<\/p>\n

gsm-utils<\/strong>
\nPackage: gsmlib_1.10.orig.tar.gz <\/a>
\nThis project is quite old and unmaintained. If you compile it with a recent gcc (I was using 4.3.x), you’ll need to apply this patch<\/a> provided by Debian. The building procedure is straight-forward, but the results, at least for me, were quite disapointing because the SMS daemon crashed very often.<\/p>\n

gammu<\/strong>
\nPackage: gammu-1.31.0.tar.bz2<\/a>
\nGammu is a fork of gnokii (the third option), it’s well documented, it’s robust and more complex, and it has a lot of features making it a bit heavier than gnokii. If your hardware is a PC or a high-end ARM processor I would recommend gammu. It also depends on libdbi that implements a database-independent abstraction layer in C, similar to the DBI\/DBD layer in Perl.
\nSince I can only use SQLite3, I don’t need the portability to other databases making the use of libdbi redundant.<\/p>\n

gnokii<\/strong>
\nPackage: gnokii-0.6.31.tar.bz2<\/a>
\nGnokii is a set of tools, similar to gammu that allows to send\/receive SMS, read\/write to a phonebook and other services. I was only interested in the SMS functionality that seemed to cover quite well.
\ngnokii’s SMS daemon, smsd<\/em>, is quite light, making it suitable for small ARM processors like the one I have.
\nLatest versions support SQLite3 so I could even put the two tables that smsd uses for sending and receiving SMS inside my database.<\/p>\n

The documentation is not great, but good enough to get started. The code is quite clear and easy to understand. In fact, I found a memory leak in smsd that I fixed and sent to the mailing list. The patch was applied quite fast showing the active development around this project.<\/p>\n

I decided to use gnokii and document its building procedure since the cross-compilation is not straight forward. <\/p>\n

This is the procedure I followed:<\/p>\n

Set the following environment variables that will make our life easier:<\/p>\n

\n$ export BUILD=i386-linux\n$ export HOST=arm-linux\n$ export PROJECT_PATH=\/home\/projects\/rootfs\n<\/pre>\n
Configure:<\/p>\n
\nGLIB_CFLAGS=\"-I$PROJECT_PATH\/usr\/include\/glib-2.0 -I$PROJECT_PATH\/usr\/lib\/glib-2.0\/include\" \nGLIB_LIBS=\"-L$PROJECT_PATH\/usr\/lib\" \nSQLITE3_CFLAGS=\"-I$PROJECT_PATH\/usr\/include\" \nSQLITE3_LIBS=\"-L$PROJECT_PATH\/usr\/lib\" \n.\/configure \n--build=$BUILD \n--host=$HOST \n--without-x \n--without-bluetooth \n--without-libical \n--disable-libusb \n--disable-phonet \n--enable-sqlite \n--disable-xdebug\n<\/pre>\n
Before building, edit the following Makefiles:<\/p>\n
    \n
  1. common\/phones\/Makefile<\/li>\n
  2. common\/links\/Makefile<\/li>\n
  3. common\/devices\/Makefile<\/li>\n
  4. common\/data\/Makefile<\/li>\n
  5. gnokii\/Makefile<\/li>\n
  6. common\/Makefile<\/li>\n
  7. utils\/Makefile<\/li>\n
  8. gnokiid\/Makefile<\/li>\n<\/ol>\n
    Unset the variable LIBS<\/em>:<\/p>\n
    \nLIBS =\n<\/pre>\n
    Edit the files gnokii\/Makefile<\/em> and gnokiid\/Makefile<\/em>:
    \nSet the variable LIBS<\/em> to the following value:<\/p>\n
    \nLIBS =  -L\/home\/projects\/rootfs\/usr\/lib -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lglib-2.0\n<\/pre>\n
    Edit the file smsd\/Makefile<\/em>:
    \nSet the variable GLIB_LIBS<\/em> to the following value:<\/p>\n
    \nGLIB_LIBS = -L\/home\/projects\/rootfs\/usr\/lib -lsqlite3\n<\/pre>\n
    Set the variable CFLAGS<\/em> to the following value:<\/p>\n
    \nCFLAGS = -g -O2 -Wall -Wno-pointer-sign -fvisibility=hidden -fno-strict-aliasing -I\/home\/projects\/rootfs\/usr\/include\n<\/pre>\n
    Now you can build and install in \/home\/projects\/rootfs\/usr\/local<\/em>:<\/p>\n
    \nmake\nmake DESTDIR=$PROJECT_PATH\/usr\/local install\n<\/pre>\n
    Gnokii still has some rough edges that can be fixed\/improved, but after  a couple of months of intensive use its behaviour has been quite stable.<\/p>\n","protected":false},"excerpt":{"rendered":"
