Hmm, OK, I think I see what's going on here. There are two i2c-tools branches: the stable branch (3.1) and the development branch (SVN trunk.) The patch I sent was for the development branch. One important difference between the two branches is that, in the stable branch, the i2c API is implemented as a set of inline functions, while in the development branch it is a library. I don't think that py-smbus was properly ported so most likely it was already broken before my patch. I suppose you are using SVN trunk and this is why you have this linking problem? If that is the case, then maybe the following patch will do the trick: --- py-smbus/Module.mk | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- i2c-tools.orig/py-smbus/Module.mk 2012-04-26 12:05:55.351086796 +0200 +++ i2c-tools/py-smbus/Module.mk 2015-01-22 11:47:06.524806243 +0100 @@ -12,7 +12,7 @@ PY_SMBUS_DIR := py-smbus PYTHON ?= python DISTUTILS := \ cd $(PY_SMBUS_DIR) && \ - CPPFLAGS="$(CPPFLAGS) -I../include" $(PYTHON) setup.py + CPPFLAGS="$(CPPFLAGS) -I../include" LDFLAGS="$(LDFLAGS) -Llib -li2c" $(PYTHON) setup.py all-python: $(INCLUDE_DIR)/i2c/smbus.h $(DISTUTILS) build But please keep in mind that my python knowledge is non-existent so it might be plain wrong.
