Conflict between sip and sip3

[willdlcre]

Hi everyone,

I'm trying to build an image including the python3-pyqt5 package. However, during the do_rootfs task of my image recipe's build, I got this error :

 * Solver encountered 1 problem(s):
 * Problem 1/1:
 *   - nothing provides sip3 = 4.19.2-r0 needed by sip3-dev-4.19.2-r0.cortexa9hf-neon
 * 
 * Solution 1:
 *   - do not ask to install a package providing sip3-dev

I've seen in the python3-pyqt5 recipe that there are dependencies to both sip-native and sip3-native. From the sip3 recipe, i've tried to remove this portion of code :

# we are inrterested in python3 modules only - for other stuff build sip
rm -rf ${D}/${includedir}
rm -rf ${D}/${bindir}

Which drove me to another error saying that there is a conflict between sip and sip3, and bitbake won't install the same files twice at the same place.

I'm stuck on that for a moment now, any help would be appreciated ! :-)

I have python3-pyqt5 in my image and it depends on

"python3-pyqt5" -> "libc6"
"python3-pyqt5" -> "libgcc1"
"python3-pyqt5" -> "libqt5svg5"
"python3-pyqt5" -> "libstdc++6"
"python3-pyqt5" -> "python3-core"
"python3-pyqt5" -> "python3-sip"
"python3-pyqt5" -> "qtbase"

The question is: What causes your image to contain sip3-dev? To find out: enable buildhistory. That creates a file depends.dot. Search there for sip3-dev (and let me know :)

Hi Andreas, thanks for your answer! I've checked a few output files and looked for the occurences of 'sip' Here is what I found :

• From installed-packages.txt:

python3-sip_4.19.2-r0_cortexa9hf-neon.ipk

*From depends.dot :

"python3-pyqt5" -> "libc6" "python3-pyqt5" -> "libgcc1" "python3-pyqt5" -> "libqt5svg5" "python3-pyqt5" -> "libstdc++6" "python3-pyqt5" -> "python3-core" "python3-pyqt5" -> "python3-sip" "python3-pyqt5" -> "qtbase" "python3-pyqt5" -> "qtwebkit"

There is no other occurence of 'sip' in depends.dot

From the /build/tmp/deploy/ipk/cortexa9 directory :

./sip_4.19.2-r0_cortexa9hf-neon.ipk ./python-sip_4.19.2-r0_cortexa9hf-neon.ipk ./sip3-dbg_4.19.2-r0_cortexa9hf-neon.ipk ./sip3-dev_4.19.2-r0_cortexa9hf-neon.ipk ./sip-dbg_4.19.2-r0_cortexa9hf-neon.ipk ./sip-dev_4.19.2-r0_cortexa9hf-neon.ipk

From sip3_4.19.2-pyqt5.bb DEPENDS += "sip sip-native sip3-native qtbase python3" DEPENDS_append_class-target = "qtsvg qtwebkit"

FILES_sip3 = "${libdir}/${PYTHONDIR}/site-packages/" FILES${PN}-dbg += "${libdir}/${PYTHON_DIR}/site-packages/.debug"

From python3pyqt5.bb: RDEPENDS${PN}_append_class-target = " python3-core python3-sip"

It seems that Bitbake always create a -dev package (same for -doc, -staticdev, -dbg etc...) but I don't understand why sometimes those packages are installed on the image, and sometimes not. I don't really understand how the PACKAGE/FILES system work anyway...

Hope those information can help..

For your understanding: dev packages are created for each recipe. By default dev packages require base package being installed/part of the image. For your case: sip3-dev requires sip3. Since sip3 is empty and recipe does not contain ALLOWEMPTY${PN} = "1", do_rootfs fails.

So the problem is sip3-dev. What in your environment causes sip3-dev being added to your image?

• What does depends.dot say for sip3-dev?
• Do you have other -dev files in your image?

Maybe you drop your depends.dot somewhere so I can take a look...

For whatever reason your image contains sip3-devel (let's ignore)- the issue you reported caused me to look into and unveiled that python3-pyqt5 was built in the wrong way: It used sip (for python V2) to create bindings which is not a good idea when using python3. That (and the problem causing trouble for you) should be fixed. Please pull latest master and let me know.

I’m starting the image build from scratch to be sure I don’t keep any wrong packages or anything else. I’ll tell you if the problem is fixed for me :-)

About the depends.dot file (for the previously generated image) what is weird is that ”sip3-dev” does not appear anywhere. Neither as a package itself or as a dependency...

I’ve also ran bitbake -g -u taskexp demo-image to check out all the task listed and still no trace of sip3-dev...
