linkwhole test case fails on OpenBSD
Summary
TEST="linkwhole" gmake test currently fails on OpenBSD
Steps to reproduce
=====> 1 of 1 [0, 0, 0]
$ TEST="linkwhole" gmake test
...
linkwhole(normal) 1 of 1 [0, 0, 0]Wrong exit code for linkwhole()(expected 0 , actual 2 )
Stderr ( linkwhole ):
host: lib.so: unknown symbol `base_GHCziNum_zdfNumInt_closure'
host: Could not load Object Code lib.so.
host: Unable to resolve objects for lib.so
gmake[1]: *** [Makefile:20: linkwhole] Error 1
*** unexpected failure for linkwhole(normal)Expected behavior
The test should pass.
Environment
- GHC version used: 9.3 (commit 6cea7311)
Optional:
- Operating System: OpenBSD 7.0-current with clang 13
- System Architecture: amd64
More details
This test checks -fwhole-archive-hs-libs related behavior which is documented as
This is for specialist applications that may require symbols defined in these Haskell libraries at runtime even though they aren’t referenced by any other code linked into the executable. If you’re using -fwhole-archive-hs-libs, you probably also want -rdynamic.
and -rdynamic in turn is documented as:
This instructs the linker to add all symbols, not only used ones, to the dynamic symbol table. Currently Linux and Windows/MinGW32 only. This is equivalent to using -optl -rdynamic on Linux, and -optl -export-all-symbols on Windows.
Based on these I wouldn't expect the test to actually work on OpenBSD, but the failure mode is somewhat strange. Note that the test goes all the way until ./host lib.so runs. At this point, with LD_DEBUG I get more information:
