Bug ID: 11016
Summary: Wrong compiler used for external user host packages
Product: buildroot
Version: unspecified
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: ian_ormshaw at waters.com
CC: buildroot at uclibc.org
Target Milestone: ---
I am building on CentOs from the head of master.
I have a number of packages in the BR2_EXTERNAL file structure that require
c++14 to compile. I have configured buildroot to use gcc 7. However for host
packages the native compiler is being used not the one built as a part of
buildroot. The build output and package config files are included below.

--- Comment #1 from Dr I J Ormshaw <ian_ormshaw@waters.com> ---
The CMakeLists file used with that config was:
cmake_minimum_required(VERSION 3.0.2)
project(linuxLibraries)
set(CMAKE_C_STANDARD_REQUIRED -std=gnu++14)
add_compile_options(-fPIC -Wall -Wextra -Werror)
add_subdirectory(libTime)
add_subdirectory(libLock)
add_subdirectory(libRegularExpression)
add_subdirectory(libApplication)
add_subdirectory(libStatistic)
add_subdirectory(libSocket)
add_subdirectory(libXmlDocument)
add_subdirectory(libFifo)
add_subdirectory(libHash)
add_subdirectory(libDiskEvents)
The make file:
################################################################################

Buildroot does not build its own native compiler (i.e. the compiler used to
build host-packages). We don't plan to do so. It would increase the complexity
significantly.
Instead, Buildroot can exclude packages that require a recent native compiler,
using the symbols BR2_HOST_GCC_AT_LEAST_X_Y. So in your case, you could add
'depends on BR2_HOST_GCC_AT_LEAST_5' to the Config.in of
amstParseSharedLibraries. Clearly, that doesn't solve your problem because you
simply will not be able to build your packages.
However, you can fairly easily build gcc7 yourself and install it somewhere in
your PATH.
