commit c5817a0dafc67882f15730ee818fbcdba1b7b915 Author: David Goulet dgoulet@torproject.org Date: Wed Jan 13 09:48:45 2021 -0500
m4: Change LIBS order of TOR_SEARCH_LIBRARY()
Some gcc versions do explode if the order of the linker flags are not correct. One issue was statically building OpenSSL which would require that "-lssl -lcrypto" be put _before_ the "-lpthread -ldl" flags.
I have not such problem with GCC 10 but does with GCC 9.
Closes #33624
