Missing plpgsql.o Symbols on OS X

Hackers,

I’m trying to build Pavel’s plpgsql_check against the 9.4 beta on OS X 10.9, but get these errors:

make
gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendif-labels -Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -I/usr/local/pgsql/lib/pgxs/src/makefiles/../../src/pl/plpgsql/src -bundle -multiply_defined suppress -o plpgsql_check.so plpgsql_check.o -L/usr/local/pgsql/lib -L/usr/local/lib -L/usr/local/lib -Wl,-dead_strip_dylibs -bundle_loader /usr/local/pgsql/bin/postgres
Undefined symbols for architecture x86_64:
"_exec_get_datum_type", referenced from:
_check_target in plpgsql_check.o
"_plpgsql_build_datatype", referenced from:
_check_stmt in plpgsql_check.o
"_plpgsql_compile", referenced from:
_check_plpgsql_function in plpgsql_check.o
"_plpgsql_parser_setup", referenced from:
_prepare_expr in plpgsql_check.o
"_plpgsql_stmt_typename", referenced from:
_put_error in plpgsql_check.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [plpgsql_check.so] Error 1

Which is odd, because plpgsql_check.c includes plpgsql.h, and those symbols do appear to be in plpgsql.so:

$ nm /usr/local/pgsql/lib/plpgsql.so | grep _exec_get_datum_type
000000000000f110 T _exec_get_datum_type
000000000000f380 T _exec_get_datum_type_info

So, uh, what gives? Do I need to something extra to get it to properly find plpgsql.so?

Thanks,

David

Yeah, but plpgsql.so is mentioned nowhere on your command line.

I'm not too sure about the dynamic-linking rules on OS X, but I'd not be
surprised if you need to provide a reference to plpgsql.so in its final
installed location (ie, a reference to it in the build tree may appear to
link and then fail at runtime).

Please add -arch x86_64 to your LD_FLAGS and CFLAGS in your make file.

This made no difference:

LDFLAGS = -arch x86_64
CFLAGS = -arch x86_64

Best,

Ah. Is there a recommended way to do that in a PGXS-powered Makefile?
