Preface: Don't use wsl ubuntu to compile, the kernel is different, there will be a lot of mistakes, I have switched to vmware to install the virtual machine! !
Compile sdk **
[Don't look at the following, it's useless, if the following error occurs, please don't use wsl anymore, go to vmware to create a virtual machine, you can refer to other articles] **
At that time, I used the uname -a command to check the kernel version, and a bunch of things were added to the ubuntu of wsl, which was not recorded at that time!
In short, it is different! ! ! Don't use wsl! ! ! At that time, I was compiling the same thing as my colleague, and I made mistakes everywhere and was delayed for a week.
Error in last step:
package/rockchip/rkmedia/Config.in:113:error: recursive dependency detected!
package/rockchip/rkmedia/Config.in:113: symbol BR2_PACKAGE_RKMEDIA_ROCKFACE_RECOGNIZE depends on BR2_PACKAGE_ROCKFACE_FACE_RECOGNITION
package/rockchip/rockface/Config.in:37: symbol BR2_PACKAGE_ROCKFACE_FACE_RECOGNITION is selected by BR2_PACKAGE_RKMEDIA_ROCKFACE_RECOGNIZE
Recursive dependency error

***Supplementary learning: https://www.kernel.org/doc/html/latest/kbuild/makefiles.html
In the Kconfig file:
config A
depends on B
select C
Its meaning is: whether CONFIG_A is configured or not depends on whether CONFIG_B is configured. Once CONFIG_A is configured, CONFIG_C is also automatically configured.
3.
depends on means that the symbol ( )=y must have been selected to configure this option. For example, depends on FB && (ZORRO || PCI) means, and (&&) or (||) must be chosen. For something like that, this determines whether an option will appear. The FBZORROPCI make menuconfig
select actively sets symbols. For example, select FB_CFB_FILLRECT would mean FB_CFB_FILLRECT=y. This satisfies potential dependencies of some other configuration options. Note that the kernel documentation discourages its use for "visible" symbols (which can be selected/deselected by the user) or symbols which themselves have dependencies, as these will not be checked.
Attempt to solve 1:
Find the wrong file location:
Try removing line 115: depends on BR2_PACKAGE_ROCKFACE_FACE_RECOGNITION
Recompile:
The error of recursive dependency detection that appeared before did not appear, but it still showed that the compilation failed.
Try to solve 2:
see this sentence:
Remove this line 118 select:
compile: still the same error

3.https://pkgs.org/download/libc6-i386
4.https://pkgs.org/download/libc6-dev-i386
Question:
libc6-i386 can be installed but libc6:i386 cannot be installed, and the error is still the one above.
Workaround:
Steps:
// Judge your own architecture (my output amd64)
$ dpkg --print-architecture
// Add i386 architecture
$ dpkg --add-architecture i386
// update it
Installed successfully.
Reason for analysis: libc6:i386 is a 32-bit package that cannot be installed under the amd64 architecture. Here we need to install other architectures, which can be used during cross-compilation.
Tried to recompile:
still fails:
Check the soft link, it exists.
And a recursive dependency error is detected when source envsetup.sh :
Therefore, I decided to follow the previous modification: delete the select statement in buildroot/package/rockchip/rkmedia/Config.in: line 118.
And according to the error: It is suspected that the versions of the two libraries are generally different before the system is different. If the compiled executable program and related library files are directly placed on the deployment machine, major problems will likely occur
Installation: sudo apt-get install lib32gcc-7-dev g+±7 libstdc+±7-dev
The first two installations are completed
, but the last libstdc+±7-dev cannot be installed: the reason is that the package name is wrong!
So far, all the installation packages required in the environment configuration document have been installed.
Still getting an error!

It may be that some necessary dependent software has not been installed [Excluded, installed according to the document]
2. The version of the cross compiler is inconsistent with the generated makefile.
Solution: Check the makefile to regenerate a consistent version
3. It may also be that the permissions are not enough. (This will prompt) [Exclude]

Finish.
(2) Install libform.so
The list of downloaded files is:
There are more s than those in the log file.
(3) Install libpanel.so
The name is also different here.
(4) Install libmenu.so
The name is also different here.
The above installation is complete.
Check in the directory usr/lib/, and found that there are all these 4 packages, and the names are correct. like:
Recompile!
It is suspected to be a problem with the installation package, and the comparison between wsl and cx directly downloads the installation package of the virtual machine
Mine is only 1365:
There are 2036 of Cx.
Reinstall according to cx
There should be a problem here:

About the ldconfig command:
*** http://lnmp.ailinux.net/ldconfig
The purpose of the ldconfig command is mainly to search in the default directory /lib and /usr/lib and the dynamic library configuration file /etc/ld.so.conf In the listed directory, search out the shareable dynamic link library (format such as lib*.so*), and then create the connection and cache files required by the dynamic loader (ld.so). The default cache file is /etc/ld.so.cache, which saves the sorted list of dynamic link library names. In order to make the dynamic link library shared by the system, the management command ldconfig of the dynamic link library needs to be run. This execution program Stored in the /sbin directory.
ldconfig usually runs when the system starts, and when the user installs a new dynamic link library, you need to run this command manually.

Therefore, this problem is mainly solved:
to view the version of a single package, use the command:
examine:
Found: The i386 version does not install the package!
Execute the installation command:
Check the other three packages and find the same problem:
That is: installing packages on wsl ubuntu, if not explicitly stated, will only install the amd64 version.
So install the above i386 version.
Restart the ldd command:

Description and solution of kconfig recursion problem¶
Pictured: https://www.kernel.org/doc/html/latest/kbuild/kconfig-language.html
Developers experiencing problems with recursive Kconfigs have two options. We document them below and provide a list of historical issues resolved by these various solutions.
Remove any redundant "select FOO" or "depends on FOO"
Match dependency semantics:
b1) swap all "select FOO" with "depends on FOO", or,
b2) swap all "depends on FOO" with "selects FOO"
The solution to a) can be tested using the example Kconfig file Documentation/kbuild/Kconfig.recursion-issue-01 by removing "select CORE" from CORE_BELL_A_ADVANCED, as this is already implied since CORE_BELL_A depends on CORE. Sometimes it may not be possible to remove some dependencies, for which case you can use solution b). Two different resolutions for b) can be tested in
the sample Kconfig file Documentation/kbuild/Kconfig.recursion-issue-02. Below is a list of previously fixed examples for these types of recursion problems; all bugs seem to involve one or more "select" statements and one or more "depends on".
