[FreeBSD 12.1] rugged.so finding libssh2.so, but not linking to it

[rucarrol]

Hey,

This issue seems to be similar to a previous, older issue ( #366 ).

I'm building rugged on FreeBSD12.2, in a Jail.

Initial gem install rugged fails, so I tried to debug what is happening in the directory left behind.

First, I create the Makefile with ruby extconf.rb (Full output here: https://pastebin.com/kjkxhrVP). Filtered output here:

-- Found ZLIB: /usr/lib/libz.so (found version "1.2.11") 
-- Checking for module 'libssh2'
--   Found libssh2, version 1.9.0
--   Resolved libraries: /usr/local/lib/libssh2.so
-- Looking for libssh2_userauth_publickey_frommemory in /usr/local/lib/libssh2.so
-- Looking for libssh2_userauth_publickey_frommemory in /usr/local/lib/libssh2.so - found

This looks more or less good. Next I run make (Full output: https://pastebin.com/2rjedAde ). Nothing to note here.

However when I check to see if we've resolved the functions in libssh2.so:

root@gitlab:/usr/local/lib/ruby/gems/2.7/gems/rugged-1.1.0/ext/rugged # nm rugged.so | grep libssh2_userauth_publickey_frommemory
                 U libssh2_userauth_publickey_frommemory

And from ldd libssh2.so.1:

root@gitlab:/usr/local/lib/ruby/gems/2.7/gems/rugged-1.1.0/ext/rugged # ldd /usr/local/lib/libssh2.so.1
/usr/local/lib/libssh2.so.1:
	libz.so.6 => /lib/libz.so.6 (0x8006ae000)
	libssl.so.111 => /usr/lib/libssl.so.111 (0x8006ca000)
	libcrypto.so.111 => /lib/libcrypto.so.111 (0x800e00000)
	libc.so.7 => /lib/libc.so.7 (0x80024e000)
	libthr.so.3 => /lib/libthr.so.3 (0x800762000)

root@gitlab:/usr/local/lib/ruby/gems/2.7/gems/rugged-1.1.0/ext/rugged # ls -lh /usr/local/lib/libssh2.so*
lrwxr-xr-x  1 root  wheel    16B Jan 29 17:11 /usr/local/lib/libssh2.so -> libssh2.so.1.0.1
lrwxr-xr-x  1 root  wheel    16B Jan 29 17:11 /usr/local/lib/libssh2.so.1 -> libssh2.so.1.0.1
-rwxr-xr-x  1 root  wheel   245K Jan 29 17:11 /usr/local/lib/libssh2.so.1.0.1

Full Makefile : https://pastebin.com/YGwSv7V3

And outputs form pkg-config:

root@gitlab:/usr/local/lib/ruby/gems/2.7/gems/rugged-1.1.0/ext/rugged # pkg-config --libs --static ../../vendor/libgit2/build/libgit2.pc 
-L/usr/local/lib -lgit2 -lrt -lpthread -lz -L/usr/local/lib -lssh2 -L/usr/local/lib -lssl -L/usr/local/lib -pthread -lcrypto -pthread 

I'm really unsure how to proceed with debugging this further. Would anyone be able to give me some pointers please?

After rebuilding the jail 3 times, this went away. Going to resolve this as it seems an odd transient issue.
