C client multi-threaded test suite fails to compile on ARM architectures.
-------------------------------------------------------------------------
Key: ZOOKEEPER-1374
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1374
Project: ZooKeeper
Issue Type: Bug
Components: c client
Affects Versions: 3.3.4
Environment: Ubuntu 12.04 (precise) armel or armhf
Reporter: James Page
Priority: Minor
The multi-threaded test suite fails to build on ARM architectures:
g++ -DHAVE_CONFIG_H -I. -I./include -I./tests -I./generated -D_FORTIFY_SOURCE=2
-DUSE_STATIC_LIB -DTHREADED -DZKSERVER_CMD="\"./tests/zkServer.sh\"" -Wall -g
-MT zktest_mt-ThreadingUtil.o -MD -MP -MF .deps/zktest_mt-ThreadingUtil.Tpo -c
-o zktest_mt-ThreadingUtil.o `test -f 'tests/ThreadingUtil.cc' || echo
'./'`tests/ThreadingUtil.cc
/tmp/ccqJWQRC.s: Assembler messages:
/tmp/ccqJWQRC.s:373: Error: bad instruction `lock xaddl r4,[r3,#0]'
/tmp/ccqJWQRC.s:425: Error: bad instruction `lock xchgl r4,[r3,#0]'
gcc does provide alternative primitives (_sync_*) which provide better cross
platform compatibility; but that does make the assumption that a) gcc is being
used or b) the primitives are provided by alternative compilers.
