nrf connect sdk build use wrong compiler

[Muhammad Salman Galileo]

i try to build simple hello world program in c++. it successfully compile just yesterday, but somehow it fail to compile now. on the log it seem to use /usr/bin/c++ to compile. is it suppose to use that? here is the log file.

Do you get the same error if you try to build a different project, like Blinky? 
Have you tested one of the NRF samples?

Try to remove the build folde?

Jonathan

[Muhammad Salman Galileo]

i try to remove build folder and it does nothing. this is the cmakefiles.txt that i used.

# SPDX-License-Identifier: Apache-2.0
cmake_minimum_required(VERSION 3.20.0)
option(BUILD_TESTS "Build test programs" OFF)
project(semudah)

# if(BUILD_TESTS)
#   add_subdirectory(src)
#   add_subdirectory(tst)
# else()
find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})

target_sources(app PRIVATE src/main.cpp)

# endif()

i try to build new blinky application and its build just fine.

i didnt see any difference in cmake file.

[JONATHAN LL]

So the issue is solved? or is there still errors when building hello world?

Regards,
Jonathan

[Muhammad Salman Galileo]

it solved. it seem the problem happend because i try to do custom unit test with gtest which use linux c++ compiler. i solve it by separating the test cmake file from the main cmake file.
