[HACKERS] Trouble building uuid-ossp extension in new versions of Postgres

Hello,

I have been trying to build Postgres and migrate my data to the newest version.  Postgres builds just fine, but I also need the uuid-ossp module, which used to build fine for me and now does not...

I am currently "git pull"ed to commit b645a05fc6112a4857ceac574d4aa24174a70417.

I cd into <src_trunk>/contrib/uuid-ossp, and type "make" and this happens (on Mac, see compiler version below):

$ make
gcc -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendif-labels -Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -Wno-unused-command-line-argument -O2  -I../../contrib/pgcrypto -I. -I. -I../../src/include   -c -o uuid-ossp.o uuid-ossp.c

uuid-ossp.c:282:23: error: use of undeclared identifier 'uuid_s_ok'
                                uint32_t        status = uuid_s_ok;
                                                         ^
uuid-ossp.c:285:5: warning: implicit declaration of function 'uuid_create' is invalid in C99 [-Wimplicit-function-declaration]
                                uuid_create(&uu, &status);
                                ^
uuid-ossp.c:287:19: error: use of undeclared identifier 'uuid_s_ok'
                                if (status == uuid_s_ok)
                                              ^
uuid-ossp.c:289:6: warning: implicit declaration of function 'uuid_to_string' is invalid in C99 [-Wimplicit-function-declaration]
                                        uuid_to_string(&uu, &str, &status);
                                        ^
uuid-ossp.c:290:20: error: use of undeclared identifier 'uuid_s_ok'
                                        if (status == uuid_s_ok)
                                                      ^
uuid-ossp.c:306:19: error: use of undeclared identifier 'uuid_s_ok'
                                if (status != uuid_s_ok)

...


I can post the rest of the errors if needed but it just keeps going, eventually erroring out with "Too many errors".  Indeed I do not see the identifier 'uuid_s_ok' defined anywhere within the contrib/uuid-ossp tree.

The code that is failing to build dates to Tom Lane's commit b8cc8f94730610c0189aa82dfec4ae6ce9b13e34 in which he is apparently creating an abstraction layer for uuid-ossp to be built with any of 3 different backends.  I was looking for documentation about how to choose a backend / more details on how to build this extension now, but drawing a blank.

Again I am on a Mac, this is my compiler info:

$ clang -v
Apple LLVM version 7.0.2 (clang-700.1.79)
Target: x86_64-apple-darwin14.0.0
Thread model: posix

Thanks much!
Ryan

I think the key question is what version of the ossp code are you using?
We've had lots of reports of *that* failing to build on modern platforms,
but since development on it stopped years ago, it's not exactly a moving
target.  I'm surprised to hear of a case where you can still build the
ossp code but our code then fails.  Also, when was "used to"?

On Mac, the recommended thing is to forget about the ossp code and
use "configure --with-uuid=e2fs".  Sorry if that wasn't clear enough.

Reading over your post again, it sounds like you're trying to force-build
contrib/uuid-ossp without having used any of the configure options that
are supposed to enable it.  I'm not sure that would ever have worked very
reliably.

Ok thanks, I'll try this.

Ok, that makes sense.  I had never learned the proper procedure for building extensions, but have had success with going into e.g. contrib/pgcrypto and typing make to build the pgcrypto extension.  Since things like that have generally worked for me I didn't learn about the proper flags etc.

I'll try some more things and get back to you, thanks for the help.
 
Best,
Ryan

Thanks Tom, "uuid-ossp" built perfectly with "--with--uuid=e2fs".
 
Cheers and Happy Holidays!
