Tsz Wo (Nicholas), SZE commented on HADOOP-4949:
------------------------------------------------
- After compiled the native library, some generated files are overwritten. For
examples,
{noformat}
M src/native/configure
M src/native/Makefile.in
M src/native/src/org/apache/hadoop/io/compress/zlib/Makefile.in
M src/native/lib/Makefile.in
M src/c++/pipes/aclocal.m4
M src/c++/pipes/configure
M src/c++/utils/configure
? src/c++/libhdfs/autom4te.cache
M src/c++/libhdfs/Makefile.in
{noformat}
The changes depend on which the ant command parameters used. Should we add
these files to the ignore list?
- The compilation depends on the ordering of executions. In my machine,
-* it works if
-*# ant compile -Dcompile.c++=true -Dlibhdfs=true
-*# ant compile-native
-* but if fails if
-*# ant compile-native
-*# ant compile -Dcompile.c++=true -Dlibhdfs=true
- There are different ways to compile native library. It is not clear to me
that which one should be used. e.g.
-* ant -Dcompile.c++=yes -Dcompile.native=yes -Dlibhdfs=yes compile
-* ant compile-native -Dcompile.c++=true -Dlibhdfs=true
-* ant compile -Dcompile.c++=true -Dlibhdfs=true
-* ant compile-native
