can't compile on linux 0.7.0

[kostya]

crystal eval 'p 1'
/home/kostya/crystal-0.7.0-1/bin/../embedded/lib/../lib/libevent.a(event.o): In function `detect_monotonic':
event.c:(.text+0xca2): undefined reference to `clock_gettime'
/home/kostya/crystal-0.7.0-1/bin/../embedded/lib/../lib/libevent.a(event.o): In function `gettime':
event.c:(.text+0xd86): undefined reference to `clock_gettime'
collect2: выполнение ld завершилось с кодом возврата 1

may be because of gcc

[kostya]

it compiles with -lrt -levent if i change it to -levent -lrt fixed.

[asterite]

Oh... :-(

Can you confirm that changing the order of the @[Link] declarations here fixes the problem? If so, I'll shortly release 0.7.1.

[jhass]

I can't confirm the issue over here.

[asterite]

Yes, on my trusty64 VM it doesn't happen neither...

[kostya]

can't confirm because can't recompile compiler, but changing the order in console fixed it.

cc -o 1 main.o -L /home/kostya/crystal-0.7.0-1/embedded/lib/  -lrt -levent -lpcl -lpcre -lgc -lpthread -lunwind 
/home/kostya/crystal-0.7.0-1/embedded/lib//libevent.a(event.o): In function `detect_monotonic':
event.c:(.text+0xca2): undefined reference to `clock_gettime'
/home/kostya/crystal-0.7.0-1/embedded/lib//libevent.a(event.o): In function `gettime':
event.c:(.text+0xd86): undefined reference to `clock_gettime'
collect2: выполнение ld завершилось с кодом возврата 1

cc -o 1 main.o -L /home/kostya/crystal-0.7.0-1/embedded/lib/ -levent -lrt -lpcl -lpcre -lgc -lpthread -lunwind
ok

[asterite]

So which order is the one that works? rt event or event rt?

[kostya]

-levent -lrt works with gcc
with clang order no matter.

[asterite]

I just released 0.7.1 because I think gcc might be the default for many linuxes so it's better that this always works. @kostya let me know if it works well now. Thanks for reporting, as always :-)
