How to specific LD_LIBRARY for custom c++ toolchain?

[zclllyybb]

I set my cpp toolchain in c++.local.properties. and when the make running, it shows

info: xxx/gcc Inconsistency detected by ld.so: dl-call-libc-early-init.c: 37: _dl_call_libc_early_init: Assertion `sym != NULL' failed! is ready
......
info: xxx/clang Inconsistency detected by ld.so: dl-call-libc-early-init.c: 37: _dl_call_libc_early_init: Assertion `sym != NULL' failed! is ready

It shows the same when I try to use them in the frontend interface.
This error message seems a very classic one about glibc incompatibility? But this toolchain has been running very well on this machine to compile many repositories. Idk how to find the root cause.

thanks very much for any help

maybe I should configure LD_LIBRARY_PATH=${my_toolchain}/lib ${my_toolchain}/lib/ld-linux-x86-64.so.2 in options? But what's the right way

I don't think I've seen this error before, but we do frequently set the ldPath property in our properties files. This will automatically add the necessary LD_LIBRARY_PATH variables and pass the needed rpath's to the linker.

For example we set it here https://github.com/compiler-explorer/compiler-explorer/blob/main/etc/config/c%2B%2B.amazon.properties#L381 for our Clang compilers.

well it still doesn't work after I set items like

compiler.clang_ldb_toolchain.ldPath=xxx/lib|xxx/lib/ld-linux-x86-64.so.2

for them. But I'll continue to try to figure out.
