Gtest: ошибка компиляции

Question

Я пытаюсь использовать gtest, но у меня возникают трудности. Скажите, пожалуйста, что мне делать, чтобы запустить все тесты. код, который я хотел бы проверить (только заголовок файла, реализация пренебрежимо)

Makefile

# A sample Makefile for building Google Test and using it in user 
# tests. Please tweak it to suit your environment and project. You 
# may want to move it to your project's root directory. 
# 
# SYNOPSIS: 
# 
# make [all] - makes everything. 
# make TARGET - makes the given target. 
# make clean - removes all files generated by make. 

# Please tweak the following variable definitions as needed by your 
# project, except GTEST_HEADERS, which you can use in your own targets 
# but shouldn't modify. 

# Points to the root of Google Test, relative to where this file is. 
# Remember to tweak this if you move this file. 
GTEST_DIR = /home/ja/gtest 

# Where to find user code. 
USER_DIR = 

# Flags passed to the preprocessor. 
CPPFLAGS += -I$(GTEST_DIR)/include `root-config --cflags --libs` 

# Flags passed to the C++ compiler. 
CXXFLAGS += -g -Wall -Wextra 

# All tests produced by this Makefile. Remember to add new tests you 
# created to the list. 
TESTS = sample1_unittest 

# All Google Test headers. Usually you shouldn't change this 
# definition. 
GTEST_HEADERS = $(GTEST_DIR)/include/gtest/*.h \ 
       $(GTEST_DIR)/include/gtest/internal/*.h 


# House-keeping build targets. 

all : $(TESTS) 

clean : 
    rm -f $(TESTS) gtest.a gtest_main.a *.o 

# Builds gtest.a and gtest_main.a. 

# Usually you shouldn't tweak such internal variables, indicated by a 
# trailing _. 
GTEST_SRCS_ = $(GTEST_DIR)/src/*.cc $(GTEST_DIR)/src/*.h $(GTEST_HEADERS) 

# For simplicity and to avoid depending on Google Test's 
# implementation details, the dependencies specified below are 
# conservative and not optimized. This is fine as Google Test 
# compiles fast and for ordinary users its source rarely changes.

# function.

Пожалуйста, дайте мне какие-либо советы, что я должен сделать, чтобы исправить всю ошибку. С наилучшими пожеланиями.

Answer 1

В ModuleTest.cc, похоже, вам необходимо либо сделать:

class ModuleTest : public ::testing::Test 
class PedestalTest : public ::testing::Test 

или:

TEST_F(PedestalTest,ShowRAWTest) { 
TEST_F(ModuleTest, ShowRAWTest) { 
... 
} 

TEST_F(PedestalTest, ComputeParametersTest) { 
TEST_F(ModuleTest, ComputeParametersTest) { 
... 
}
