Description

We are trying to cross-compile libyang 2.1.128 for FRR using custom toolchain and sysroot where we are facing issue with build not able to find PCRE2_LIBRARY

CMake Error at /usr/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:146 (message):
Could NOT find PCRE2 (missing: PCRE2_LIBRARY) (Required is at least version
"10.21")
Call Stack (most recent call first):
/usr/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:393 (_FPHSA_FAILURE_MESSAGE)
CMakeModules/FindPCRE2.cmake:63 (find_package_handle_standard_args)
CMakeLists.txt:405 (find_package)

What are the ways include PCRE2_LIBRARY ?

Version

Frr 10.0

How to reproduce

Cross compile frr on power pc architecture

Expected behavior

Libyang should have built successfully

Actual behavior

How do you build? You should include --enable-pcre2posix.

Please open an issue with the libyang people. This is not the appropriate place to get help for libyang2 issues.

We have been able to compile libyang successfully. We are following FRR's link for cross compilation (https://docs.frrouting.org/projects/dev-guide/en/latest/cross-compiling.html). We have been able to configure (../configure --enable-clippy-only) clippy but facing below issue in "make clippy-only": -

Must remake target 'lib/clippy'.

However, we have resolved the python dependencies while configuring clippy but facing python related issue again during make.
Any pointers here to resolve this issue?
