-------------------------------------
[~alonamid] pinging you again on this; if you can post instructions about
cross-compiling for RISC-V
> "stdlib.h: No such file or directory" when cross-compiling for RISC-V with

> Issue Type: Bug
> Components: C++
> Environment: RISC-V, Cross-compiling for RISC-V Linux with GCC 7.2
> Reporter: Alon Amid
> Priority: Major
>
> I’ve been attempting to cross-compile Arrow for RISC-V.
> I was trying to build Arrow with Plasma and Python, but without the
> compression libraries (snappy, brotli, zstd, lz4).
> I was getting several errors indicating that stdlib.h is missing. An example
> error is:

> When I manually checked the highlighted path
> (/home/centos/riscv-poky/build/tmp/work/riscv64-poky-linux/apache-arrow/0.7.1-r0/recipe-sysroot/usr/include),
> stdlib.h is indeed there.
> While googling for similar errors, I found these references:
> https://github.com/OpenLightingProject/ola/pull/1132,
> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70129 , which seem to describe
> a similar scenario.
> As can be seen in the example call, most of the include directories are
> included using -isystem rather than -I.
> When looking further into Arrow’s cmake files, this seems intentional:
> ./cpp/cmake_modules/ThirdpartyToolchain.cmake:include_directories(SYSTEM
> ${Boost_INCLUDE_DIR})
> ./cpp/cmake_modules/ThirdpartyToolchain.cmake: include_directories(SYSTEM
> ${GTEST_INCLUDE_DIR})

> ./cpp/cmake_modules/ThirdpartyToolchain.cmake: include_directories(SYSTEM
> ${RAPIDJSON_INCLUDE_DIR})
> ./cpp/cmake_modules/ThirdpartyToolchain.cmake: include_directories(SYSTEM
> ${FLATBUFFERS_INCLUDE_DIR})

> ./python/CMakeLists.txt: include_directories(SYSTEM ${PLASMA_INCLUDE_DIR})
> Since compiling for RISC-V requires GCC 7.2, It is likely that this is the
> same issue that is exposed by using GCC version 6.0 and above is the
> previously mentioned references
> (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70129 and
> https://github.com/OpenLightingProject/ola/pull/1132)
> I mitigated the issue temporarily by setting the following in
> cpp/CMakeLists.txt:
> set(CMAKE_INCLUDE_SYSTEM_FLAG_CXX "-I ")
> However, I think this should be done anytime GCC 6.0 or higher is used.
