RE: pkg/58045: devel/lldb fails to build

[Malte Dehling <mdehling%gmail.com@localhost>]

Hi,

I've been trying to build current devel/lldb but without success, and
based on https://releng.netbsd.org/bulktracker/devel/lldb I'm not the
only one.  In fact it looks like the only successful recent builds are
on MacOS.

As per my initial bug report, the build fails with this CMake error:

    [...]
    -- Performing Test Terminfo_LINKABLE
    -- Performing Test Terminfo_LINKABLE - Failed
    -- Could NOT find Terminfo (missing: Terminfo_LINKABLE)

    [...]

    CMake Error at
/scratch/pkg/devel/lldb/work/.buildlink/lib/cmake/llvm/LLVMExports.cmake:64
(set_target_properties):
      The link interface of target "LLVMSupport" contains:

        Terminfo::terminfo

      but the target was not found.  Possible reasons include:

        * There is a typo in the target name.
        * A find_package call is missing for an IMPORTED target.
        * An ALIAS target is missing.

    Call Stack (most recent call first):

      CMakeLists.txt:37 (include)

I added this line to devel/lldb/Makefile

    CMAKE_ARGS+=	--debug-trycompile

and had a look at the CMakeConfigureLog.yaml file left behind:

        exitCode: 2

Manually running 'gcc src.c.o /usr/lib/libterminfo.so' works just fine
so I'm not sure why this fails.

Anyone know what's going on and how to fix this?

Cheers,
