-----------------------------------
Summary: Build on Ubuntu 20 ARM fails if zlib is installed
Key: KUDU-3474
URL: https://issues.apache.org/jira/browse/KUDU-3474
Project: Kudu
Issue Type: Bug
Components: build
Affects Versions: 1.17.0
Reporter: Joe McDonnell
Here is a quick note on a Kudu build failure I saw on an Ubuntu 20 ARM machine
recently. The Kudu thirdparty builds fine, but then when we get to building
Kudu it fails with this:
{noformat}
21:07:31 [ 7%] Linking CXX executable ../../../bin/protoc-gen-insertions
21:07:31
/home/ubuntu/kudu/thirdparty/src/libunwind-1.5.0/src/dwarf/Gfind_proc_info-lsb.c:140:
error: undefined reference to 'uncompress'
21:07:32 collect2: error: ld returned 1 exit status
21:07:32 make[2]: ***
[src/kudu/util/CMakeFiles/protoc-gen-insertions.dir/build.make:113:
bin/protoc-gen-insertions] Error 1{noformat}
Here's what is going on:
# libunwind's .debug_frame support is enabled for ARM/aarch64, but it is
disabled for other platforms.
[https://github.com/libunwind/libunwind/blob/master/configure.ac#L262-L276]
# The .debug_frame support uses zlib uncompress if zlib is available.
[https://github.com/libunwind/libunwind/blob/master/src/dwarf/Gfind_proc_info-lsb.c#L139-L168]
[https://github.com/libunwind/libunwind/blob/master/configure.ac#L322-L337]
# If thirdparty is built on an ARM machine that has zlib installed, then
CONFIG_DEBUG_FRAME is true and HAVE_ZLIB is true and the uncompress() reference
is compiled in.
# The Kudu build doesn't know that libunwind needs zlib, so the list of
libraries linked in for protoc-gen-insertions doesn't include zlib.
One potential fix is to add zlib as a dependency for libunwind for ARM/aarch64.
It might be worth compiling libunwind after zlib in thirdparty so that it
always has the zlib support on ARM.
