How to define dynamic list of packages

For Developers
1

Hello,

I'm creating a package for tesseract (Open Source OCR Engine). However, this software contains a lot of "data files", one for each language.

In the AUR repository, this is handled with only one package (https://git.archlinux.org/svntogit/community.git/tree/trunk/PKGBUILD?h=packages/tesseract-data), which create a package for each language.

Is possible to do something like this with the OpenWrt build system? Creating a separated package for each language would be a nightmare....

package/firmware/ipq-wifi/Makefile is one example of a (semi-)dynamically generated package that probably does much of what you need, installing a specific file based on which "variant" is requested.

Hello,

Here is the Makefile of tesseract that I'm working on: https://github.com/vk496/packages/blob/2639aaedfa44cbba905b8328ff9b7d8d3ec0b1ad/utils/tesseract/Makefile

Is there a way to avoid calling each time the generate-tesseract-data-package?

I tried to replace all that calls with a simple $(foreach PACKAGE,$(ALLTESSERACTPACKAGES),$(eval $(call generate-tesseract-data-package,$(PACKAGE)))), but the make menuconfig throws error:

ERROR: please fix package/utils/tesseract/Makefile - see logs/package/utils/tesseract/dump.txt for details
Collecting package info: done
tmp/.config-package.in:33096:error: recursive dependency detected!
For a resolution refer to Documentation/kbuild/kconfig-language.txt
subsection "Kconfig recursive dependency limitations"

With the following log:

$ cat logs/package/utils/tesseract/dump.txt
