[pocl-devel] POCL 1.4: failed with 'Undefined symbol "clGetPlatformInfo"'

[Hartmann, O. <o.h...@wa...>]

POCL 1.4 on FreeBSD seems to have introduced a mutual bug, which is not
with POCL 1.3.

Running either FreeBSD 12.1-PRE, 12-STABLE (recent version) or CURRENT
(recent version), POCL 1.4 (compiled with CLANG/LLVM 9) fails using
devel/clpeak with:

[...]

    failed with 'Undefined symbol "clGetPlatformInfo"'. note: missing
    symbols in the kernel binary might be reported as 'file not found'
    errors. Abort (core dumped)

The problem doesn't reveal itself using POCL 1.3.

Need some advice to track the problem down.

Kind regards,
