initdb on target will fail with below error:

Refer [1][2], for cross compile, --export-dynamic is assumed as not
supported, and cause above error. For oe, both gcc and clang support
--export-dynamic, fixed by set LDFLAGS_EX_BE directly

this will add all the symbols into dynamic symbol table which may not
be best scenario, can we just export the ones needed ?
perhaps look into using --dynamic-list.
Hi, Khem
I tried to use --dynamic-list as you recommended and test command "postgresql_setup
initdb",
after I added all the symbols in dict_snowball.so, it will report undefined
symbols for another lib. I know I can try to
add all the symbols for all the libs. but there are nearly 80+ libs generated
by postgresql. There will be many symbols.
And I also worried that, we may missing some symbols since I may cannot cover
all the runtime cases.
From [2], we can know that postgresql use "-Wl,--export-dynamic" before.
So maybe it is better to still use "-Wl,--export-dynamic" like before? what is
your opinion?
Yes this maybe ok. I would like you to open a discussion upstream as well.
Do you mean open an discussion about what symbols should in the symbol
files? About the the original issue
"undefined symbol: CurrentMemoryContext", Upstream said that
"Cross-compiling isn't really a supported thing".
