Linking ussie Ubuntu 16.04 (Server) about bees HOT 5 CLOSED

It looks like you have the header for uuid-dev but not the library?

from bees.

AFAIL uuid-dev is a headers + library
https://packages.debian.org/sid/uuid-dev
http://packages.ubuntu.com/search?keywords=uuid-dev

i did:

diff --git a/src/Makefile b/src/Makefile
index 1db2927..531b19c 100644
--- a/src/Makefile
+++ b/src/Makefile
@@ -7,7 +7,7 @@ all: $(PROGRAMS) depends.mk
 
 include ../makeflags
 
-LIBS = -lcrucible -lpthread
+LIBS = -lcrucible -lpthread -luuid
 LDFLAGS = -L../lib -Wl,-rpath=$(shell realpath ../lib)
 
 depends.mk: Makefile *.cc

And then i get binary 'bees' compiled

But get another error

g++ -Wall -Wextra -Werror -O3 -I../include -ggdb -fpic -std=c++11 -Wold-style-cast -o "chatter" "chatter.o" -L../lib -Wl,-rpath=/root/bees/lib -lcrucible
../lib/libcrucible.so: undefined reference to `uuid_unparse'

So, i think (may be i'm stupid and miss something) it's a Ubuntu related linking issue =
Can you please try do it yourself on U1604 Server?

Thank

I was just about to report the same bug! I have no idea why it happens, but libcrucible.so doesn't link against libuuid. For some reason bees and test need to link against libuuid.

I built a VM image of Ubuntu server 16.04 and I can reproduce the problem. I don't understand the problem yet.

libuuid.so and libuuid.so.1 both contain the uuid_parse symbol and gcc does resolve the symbol for libcrucible.so; however, it doesn't put libuuid.so in the NEEDED section of libcrucible.so so the libuuid library isn't available later on. I ran a build under strace and it seems to be doing all the right things, just with the wrong result at the end.

from bees.

FWIW bees only uses libuuid at one place, and that place is only needed if you had a v0.1 bees running. You could just delete that code.

Still, it would be nice to solve this, since it would affect any library bees might depend on in the future--and in the future, such libraries might not be as expendable as libuuid.
