Antoine Pitrou created ARROW-5192:
-------------------------------------
Summary: [C++] Bundled gRPC fails building (cannot find c-ares)
Key: ARROW-5192
URL: https://issues.apache.org/jira/browse/ARROW-5192
Project: Apache Arrow
Issue Type: Bug
Components: C++
Reporter: Antoine Pitrou
If I try to build Arrow C++ without a conda toolchain, I get the following
error when gRPC is being built by the cmake files:
{code}
CMake Error at cmake/cares.cmake:38 (find_package):
Could not find a package configuration file provided by "c-ares" with any
of the following names:
c-aresConfig.cmake
c-ares-config.cmake
Add the installation prefix of "c-ares" to CMAKE_PREFIX_PATH or set
"c-ares_DIR" to a directory containing one of the above files. If "c-ares"
provides a separate development package or SDK, be sure it has been
installed.
Call Stack (most recent call first):
CMakeLists.txt:139 (include)
{code}
It seems c-ares is found by the following line in ThirdPartyToolchain.cmake:
{code}
find_package(c-aresAlt)
{code}
But gRPC doesn't pick it up...
