PATCH 1/1 i2c-tools: Add i2c-dev.h to staging directory for userspace i2c drivers.

In reply to Jouko Nikula

Dear Jouko Nikula,

package/i2c-tools/i2c-tools.mk define I2C_TOOLS_INSTALL_TARGET_CMDS · line 25

Quoted 3 lines · Jouko Nikula
package/i2c-tools/i2c-tools.mk +3 -0

+	$(INSTALL) -D -m644 $(@D)/include/linux/i2c-dev.h $(STAGING_DIR)/usr/include/linux/
+endef

This header is already part of the kernel headers, so it should already be part of the toolchain. Do you have a specific case where this header is missing?

Best regards,

Thomas

This header is already part of the kernel headers, so it should already be part of the toolchain. Do you have a specific case where this header is missing?

This is a different header than the kernel one, although confusingly named identically. On my Debian system the libi2c-dev package provides i2c-dev.h, and diverts the kernel header to i2c-dev.h.kernel.

$ dpkg -S /usr/include/linux/i2c-dev.h
diversion by libi2c-dev from: /usr/include/linux/i2c-dev.h
diversion by libi2c-dev to: /usr/include/linux/i2c-dev.h.kernel
linux-libc-dev:amd64, libi2c-dev: /usr/include/linux/i2c-dev.h

The contents of the header are different, the one from i2c-tools contains more.

We also carry a patch similar to this. Our patch has an addition which is a dependency on linux (assuming it is selected in the config). This ensures that the header from the kernel gets over ridden by the one from i2c-tools and not the other way around.

Yes. In the kernel documentation (Documentation/i2c/dev-interface) it is explained as follows:

"So let's say you want to access an i2c adapter from a C program. The first thing to do is "#include <linux/i2c-dev.h>". Please note that there are two files named "i2c-dev.h" out there, one is distributed with the Linux kernel and is meant to be included from kernel driver code, the other one is distributed with i2c-tools and is meant to be included from user-space programs. You obviously want the second one here."

Makes sense. Could this patch be mainlined, instead of what I sent?

In fact, I will revert it: the modified i2c-dev.h by the i2c-tools has some definitions that conflicts with the i2c.h normally provided by the kernel headers. Therefore, if a userspace program or library includes both, it fails to build. This is the case with libsoc, see
http://autobuild.buildroot.org/results/1f4/1f451a338487a2a3c8a8f9b18540d41b90ee5aac/build-end.log:

Apparently, it is well-known to the i2c-tools developers that their i2c-dev.h is broken, and not really usable in practice.

Best regards,

Thomas
