About

modified conan package for gtest:

• uses git clone
• supports sanitizers, see https://github.com/google/sanitizers/wiki/MemorySanitizerLibcxxHowTo#instrumented-gtest
• uses llvm_tools conan package in builds with LLVM_USE_SANITIZER, see https://github.com/google/sanitizers/wiki/MemorySanitizerLibcxxHowTo#instrumented-gtest
• uses llvm_tools conan package in builds with libc++ (will be instrumented if LLVM_USE_SANITIZER enabled)
• etc.

See test_package/CMakeLists.txt for usage example

NOTE: use -s llvm_tools:build_type=Release during conan install

Before build

sudo apt-get update

# Tested with clang 6.0 and gcc 7
sudo apt-get -y install clang-6.0 g++-7 gcc-7

# llvm-config binary that coresponds to the same clang you are using to compile
export LLVM_CONFIG=/usr/bin/llvm-config-6.0
$LLVM_CONFIG --cxxflags

Local build

export VERBOSE=1
export CONAN_REVISIONS_ENABLED=1
export CONAN_VERBOSE_TRACEBACK=1
export CONAN_PRINT_RUN_COMMANDS=1
export CONAN_LOGGING_LEVEL=10

conan remote add conan-center https://api.bintray.com/conan/conan/conan-center False

export PKG_NAME=conan_gtest/stable@conan/stable

(CONAN_REVISIONS_ENABLED=1 \
    conan remove --force $PKG_NAME || true)

Build with sanitizers support

Use -o llvm_tools:enable_tsan=True and -e *:compile_with_llvm_tools=True like so:

export CC=$(find ~/.conan/data/llvm_tools/master/conan/stable/package/ -path "*bin/clang" | head -n 1)

export CXX=$(find ~/.conan/data/llvm_tools/master/conan/stable/package/ -path "*bin/clang++" | head -n 1)

export TSAN_OPTIONS="handle_segv=0:disable_coredump=0:abort_on_error=1:report_thread_leaks=0"

# make sure that env. var. TSAN_SYMBOLIZER_PATH points to llvm-symbolizer
# conan package llvm_tools provides llvm-symbolizer
# and prints its path during cmake configure step
# echo $TSAN_SYMBOLIZER_PATH
export TSAN_SYMBOLIZER_PATH=$(find ~/.conan/data/llvm_tools/master/conan/stable/package/ -path "*bin/llvm-symbolizer" | head -n 1)

export VERBOSE=1
export CONAN_REVISIONS_ENABLED=1
export CONAN_VERBOSE_TRACEBACK=1
export CONAN_PRINT_RUN_COMMANDS=1
export CONAN_LOGGING_LEVEL=10

# NOTE: NO `--profile` argument cause we use `CXX` env. var
