Compile error on Linux #736

Closed KonstantinWinkel closed 4 months ago

KonstantinWinkel commented 5 months ago

Observed behavior

/usr/bin/ld: CMakeFiles/nats.dir/buf.c.o:(.bss+0x0): multiple definition of `micro_ErrorInvalidArg'; CMakeFiles/nats.dir/asynccb.c.o:(.bss+0x0): first defined here
/usr/bin/ld: CMakeFiles/nats.dir/buf.c.o:(.bss+0x8): multiple definition of `micro_ErrorOutOfMemory'; CMakeFiles/nats.dir/asynccb.c.o:(.bss+0x8): first defined here

this error comes up for every file that at some point includes "nats.h"

Expected behavior

No error, just compilation

Server and client version

Latest git version ( commit 49c7f32cb9f307f909aa69d35a6f88d2bc884af4 )

Host environment

Pop!_OS 22.04 LTS x86_64

Steps to reproduce

git clone https://github.com/nats-io/nats.c
cd nats.c
mkdir build && cd build
cmake .. -DNATS_BUILD_STREAMING=OFF -DNATS_BUILD_WITH_TLS=OFF
sudo make

PROPOSED FIX: nats.h line 49: #define NATS_EXTERN extern

I'm experiencing the same issue with Ubuntu 23.10 :
