在製作GTest時出錯

我試圖在Ubuntu機器上設置GTest環境。但同時使GTEST獲得庫，我得到以下錯誤...在製作GTest時出錯

嘗試在你的G ++命令gtest_main.a後移動到-lpthread。

很好，謝謝！ – ZeroCool 2012-05-17 12:46:49

@somenath這似乎是對你的問題的直接回答，因爲我們有一個相同的問題......所以請接受它（如果確實如此）。 – SK9 2012-10-05 16:18:23

將「-L/usr/local/$（uname -m）-linux-gnu」放入您的LDFLAGS中，並在鏈接器（ld）命令行中放入「-pthread」。（是的，這是-pthread，而不是-lpthread）

你見過Erik Smistad's excellent tutorial關於如何在Ubuntu上啓動w/gtest？我剛剛在（K）ubuntu 12.04上試過了，它工作的很完美。總之，你需要做的是

sudo apt-get install cmake libgtest-dev 
cd /usr/src/gtest 
sudo cmake CMakeLists.txt 
sudo make 
sudo cp *.a /usr/lib

如果你覺得不舒服運行make和cmake的爲根，你必須到/ usr/src目錄/ GTEST由用戶複製到目錄可寫。在教程中，Erik還提供了一個帶有CMakeLists.txt的示例測試來構建它。

我有同樣的問題，我把Makefile中的-lpthread更改爲-pthread。（我退出了小'L'）。之後，一個'make'編譯沒有錯誤。

gtest-1.6.0中的文件/ make 您應該看到Makefile文件如何顯示。差異在最後一行

# 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 = .. 

# Where to find user code. 
USER_DIR = ../samples 

# Flags passed to the preprocessor. 
CPPFLAGS += -I$(GTEST_DIR)/include 

# 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. 
gtest-all.o : $(GTEST_SRCS_) 
    $(CXX) $(CPPFLAGS) -I$(GTEST_DIR) $(CXXFLAGS) -c \ 
      $(GTEST_DIR)/src/gtest-all.cc 

gtest_main.o : $(GTEST_SRCS_) 
    $(CXX) $(CPPFLAGS) -I$(GTEST_DIR) $(CXXFLAGS) -c \ 
      $(GTEST_DIR)/src/gtest_main.cc 

gtest.a : gtest-all.o 
    $(AR) $(ARFLAGS) [email protected] $^ 

gtest_main.a : gtest-all.o gtest_main.o 
    $(AR) $(ARFLAGS) [email protected] $^ 

# Builds a sample test. A test should link with either gtest.a or 
# gtest_main.a, depending on whether it defines its own main() 
# function. 

sample1.o : $(USER_DIR)/sample1.cc $(USER_DIR)/sample1.h $(GTEST_HEADERS) 
    $(CXX) $(CPPFLAGS) $(CXXFLAGS) -c $(USER_DIR)/sample1.cc 

sample1_unittest.o : $(USER_DIR)/sample1_unittest.cc \ 
        $(USER_DIR)/sample1.h $(GTEST_HEADERS) 
    $(CXX) $(CPPFLAGS) $(CXXFLAGS) -c $(USER_DIR)/sample1_unittest.cc 

sample1_unittest : sample1.o sample1_unittest.o gtest_main.a 
    $(CXX) $(CPPFLAGS) $(CXXFLAGS) $^ -o [email protected] -lpthread #<----------------------- DIFF

接下來請運行make在這個目錄:)並且很高興。
