From mboxrd@z Thu Jan 1 00:00:00 1970 From: bugzilla at busybox.net Date: Mon, 14 May 2018 08:02:57 +0000 Subject: [Buildroot] [Bug 11016] New: Wrong compiler used for external user host packages Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net https://bugs.busybox.net/show_bug.cgi?id=11016 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. >>> host-amstParseSharedLibraries custom Configuring (mkdir -p /home/ian/build/silverstone/x86_64/1c622ae/buildroot/build/host-amstParseSharedLibraries-custom/ && cd /home/ian/build/silverstone/x86_64/1c622ae/buildroot/build/host-amstParseSharedLibraries-custom/ && rm -f CMakeCache.txt && PATH="/home/ian/build/silverstone/x86_64/1c622ae/buildroot/host/bin:/home/ian/build/silverstone/x86_64/1c622ae/buildroot/host/sbin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:/home/ian/.local/bin:/home/ian/bin" PKG_CONFIG="/home/ian/build/silverstone/x86_64/1c622ae/buildroot/host/bin/pkg-config" PKG_CONFIG_SYSROOT_DIR="/" PKG_CONFIG_LIBDIR="/home/ian/build/silverstone/x86_64/1c622ae/buildroot/host/lib/pkgconfig:/home/ian/build/silverstone/x86_64/1c622ae/buildroot/host/share/pkgconfig" PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=1 PKG_CONFIG_ALLOW_SYSTEM_LIBS=1 /home/ian/build/silverstone/x86_64/1c622ae/buildroot/host/bin/cmake /home/ian/build/silverstone/x86_64/1c622ae/buildroot/build/host-amstParseSharedLibraries-custom/ -DCMAKE_INSTALL_SO_NO_EXE=0 -DCMAKE_FIND_ROOT_PATH="/home/ian/build/silverstone/x86_64/1c622ae/buildroot/host" -DCMAKE_FIND_ROOT_PATH_MODE_PROGRAM="BOTH" -DCMAKE_FIND_ROOT_PATH_MODE_LIBRARY="BOTH" -DCMAKE_FIND_ROOT_PATH_MODE_INCLUDE="BOTH" -DCMAKE_INSTALL_PREFIX="/home/ian/build/silverstone/x86_64/1c622ae/buildroot/host" -DCMAKE_C_FLAGS="-O2 -I/home/ian/build/silverstone/x86_64/1c622ae/buildroot/host/include" -DCMAKE_CXX_FLAGS="-O2 -I/home/ian/build/silverstone/x86_64/1c622ae/buildroot/host/include" -DCMAKE_EXE_LINKER_FLAGS="-L/home/ian/build/silverstone/x86_64/1c622ae/buildroot/host/lib -Wl,-rpath,/home/ian/build/silverstone/x86_64/1c622ae/buildroot/host/lib" -DCMAKE_SHARED_LINKER_FLAGS="-L/home/ian/build/silverstone/x86_64/1c622ae/buildroot/host/lib -Wl,-rpath,/home/ian/build/silverstone/x86_64/1c622ae/buildroot/host/lib" -DCMAKE_ASM_COMPILER="/usr/bin/as" -DCMAKE_C_COMPILER="/usr/bin/gcc" -DCMAKE_CXX_COMPILER="/usr/bin/g++" -DCMAKE_C_COMPILER_ARG1="" -DCMAKE_CXX_COMPILER_ARG1="" -DCMAKE_COLOR_MAKEFILE=OFF -DBUILD_DOC=OFF -DBUILD_DOCS=OFF -DBUILD_EXAMPLE=OFF -DBUILD_EXAMPLES=OFF -DBUILD_TEST=OFF -DBUILD_TESTS=OFF -DBUILD_TESTING=OFF -DCMAKE_CXX_FLAGS="-fPIC -Wall -Wextra -Wpedantic -Werror -std=gnu++14" -DAMSTPARSESHAREDLIBRARIES=On ) -- The C compiler identification is GNU 4.8.5 -- The CXX compiler identification is unknown -- Check for working C compiler: /usr/bin/gcc -- Check for working C compiler: /usr/bin/gcc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done -- Check for working CXX compiler: /usr/bin/g++ -- Check for working CXX compiler: /usr/bin/g++ -- broken CMake Error at /home/ian/build/silverstone/x86_64/1c622ae/buildroot/host/share/cmake-3.8/Modules/CMakeTestCXXCompiler.cmake:44 (message): The C++ compiler "/usr/bin/g++" is not able to compile a simple test program.
