I'm definitely interested in this.
The July 18 release on LuaForge gives me this error upon compile:
cc -Wall -Werror -O2 -g -D_GNU_SOURCE -c -o lanes.o lanes.c
In file included from /usr/include/sys/types.h:8,
/usr/include/gentoo-multilib/amd64/sys/types.h:198: error: conflicting
types for 'int64_t'
threading.h:35: error: previous declaration of 'int64_t' was here
make: *** [lanes.o] Error 1
This is, AFAIK, a 64-bit-only error, because on 64-bit machines
<types.h> includes int64_t, which you are also defining in your
However, including <sys/types.h> instead of the typedef on line 35 fixes
that error, and adding -fPIC to the CFLAGS in src/Makefile allows the
library to fully compile on a 64-bit Linux system. `make test` works
with the library compiled this way, so I guess there's no other 64-bit
I believe -fPIC should work on 32-bit systems as well (I don't really
know, though), so adding it to the Makefile's CFLAGS probably won't
cause a problem. I'm not quite sure what the best solution is for the
types.h include, as I haven't looked over the code yet.
Other than that, I haven't gotten around to any real testing yet :)
