Can you please try adding ncurses to the depends

I had to add ncurses to both host and target depends (it failed when i added only to target ).So far it seem to work ,but the build didn't completed yet,so i will let you know when it does.

pcre2 build log -> 130.log

DONE 130 3 install pcre2:target 32.0203 2.8321 117 29.7113 1660197438.6561 1660197468.3674 /home/ubuntu/LibreELEC.tv/build.LibreELEC-RPi4.arm-11.0-devel/.threads/logs/130.log

Nope, pcre2:host still fails...

Here are the logs after adding PKG_DEPENDS_TARGET="toolchain ncurses" CMakeOutput.log CMakeError.log 232.log

@heitbaum and @SupervisedThinking I've tried all your suggestions but pcre2:host still fails .

What puzzles me is that if i use PROJECT=RPi DEVICE=RPi4 ARCH=arm scripts/build pcre2 then pcre2 builds just fine.But trying the same with pcre2:host fails.

I tried to reset the master branch,distclean ,etc...no dice.

@pretoriano80 well I guess we need host build opts too 🤦🏻‍♂️😅

PKG_CMAKE_OPTS_HOST="-DBUILD_SHARED_LIBS=OFF \
                       -DBUILD_STATIC_LIBS=ON \
                       -DPCRE2_BUILD_PCRE2_8=ON \
                       -DPCRE2_BUILD_PCRE2_16=ON \
                       -DPCRE2_BUILD_PCRE2_32=ON \
                       -DPCRE2_SUPPORT_JIT=ON \
                       -DPCRE2_BUILD_TESTS=OFF \
                       -DPCRE2_SUPPORT_LIBREADLINE=OFF"

What's the result if you add something like this & might add the libedit switch @heitbaum PRed?

[heitbaum]

@pretoriano80 - can you please check your output on your build host

--   Link pcre2grep with libz ........ : Library not found
--   Link pcre2grep with libbz2 ...... : Library not found
--   Link pcre2test with libeditline . : Library not found
--   Link pcre2test with libreadline . : Library not found

The build on the my Oracle Ampere node (within the docker) for both :host and :target have the above output.

@SupervisedThinking with your host opts and @heitbaum PR now both host and target are building without errors .

[pretoriano80]

I closed it by mistake .

[pretoriano80]

Just to double check ,I've done another distclean &build image,it's all good and everything compiled just fine.
