Hi,
I'm trying to compile a single big file project written in C. It compiled fine,
without problems in my develop machine (FreeBSD 9.1 STABLE, Clang3.2) but not
on the server (FreeBSD 9.1 Release#0, Clang 3.1). The app uses openssl dtls and
links to system ssl libs. Am I missing something?
For compile I do:
%clang gog_server.c -o gog_server -v -I /usr/include/openssl
but I get a lot of undefined references to whole openssl lib functions, structs
etc in Link phase:
...
gog_server.c:(.text+0x9): undefined reference to `CRYPTO_num_locks'
gog_server.c:(.text+0x50): undefined reference to `CRYPTO_num_locks'
...
I have manually checked that:
a) /usr/lib/libssl.a /usr/lib/libssl.so exist
b) The linker has /usr/lib path
%clang -print-search-dirs
programs: =/usr/bin
libraries: =/usr/bin/../lib/clang/3.1:/usr/lib
c) Add -Xlinker "-L /usr/lib"
d) Add -Xlinker "-l /usr/lib/libssl.a", get this from linker:
"/usr/bin/ld" --eh-frame-hdr -dynamic-linker /libexec/ld-elf.so.1 -o gog_server
/usr/lib/crt1.o /usr/lib/crti.o /usr/lib/crtbegin.o -L/usr/lib
/tmp/gog_server-8bAHxn.o "-l /usr/lib/libssl.a" -lgcc --as-needed -lgcc_s
--no-as-needed -lc -lgcc --as-needed -lgcc_s --no-as-needed /usr/lib/crtend.o
/usr/lib/crtn.o
/usr/bin/ld: cannot find "-l /usr/lib/libssl.a"
e) Tried c) and d) without "", but get the same answers /usr/bin/ld: cannont
find ...
Finally, this is the relevant output of last try:
% clang gog_server.c -o gog_server -v -I /usr/include/openssl -Xlinker
/usr/lib/libssl.a 2>err

.....
and a lot of similar lines.
So, Am I missing something?
Thanks in advance.
