[question] Linux x86-64 binary linked against lockdev/liblockdev

[splatch]

Hey, I am running two kinds of linux machines - one is my developer box powered by arch, another is embedded linux distro made with yocto. In both cases I ran into issues with locks. At least for arch lock dir (/var/run/lock) does exist, permissions are fine for all software but not for rxtx/nrjavaserial.

I started to look at never ending topic of locks #60 and some other issues. I would love to see issue fixed since my embedded linux is also x86-64. How to get make linux64 produce binary linked against lockdev?

If you're comfortable building your own native binaries, probably the easiest workaround to locking issues at the moment is to build with DISABLE_LOCKFILES defined – edit src/main/c/Makefile and add -DDISABLE_LOCKFILES to the CFLAGS definition:

diff --git a/src/main/c/Makefile b/src/main/c/Makefile
index 90d43bd..3ff9359 100644
--- a/src/main/c/Makefile
+++ b/src/main/c/Makefile
@@ -63,7 +63,8 @@ include platform.mk
 # it will work as a library (dlopen(3) et al. can load it into any memory).
 export CFLAGS ?= -I$(JAVA_HOME)/include -I./include -I./include/target \
                    -O3 -fPIC -c \
-                   -Wall
+                   -Wall \
+                   -DDISABLE_LOCKFILES
 # We want to use the compiler frontend to invoke the linker, too.
 export LD = $(CC)
 # We want to link objects into a shared library.

Then you can make clean-linux64 linux64.
