How to compile cpp gtest file?

Question

In Ubuntu Linux, I follow the instructions gtestlisted here is to set the gtestmanual copying of header files and libraries at /usr/includeand /usr/lib, respectively.

Then I tried to compile the following code ( test1.cpp)

#include <gtest/gtest.h>
TEST(MathTest, TwoPlusTwoEqualsFour) {
    EXPECT_EQ(2 + 2, 4);
}

int main(int argc, char **argv) {
    ::testing::InitGoogleTest( &argc, argv );
    return RUN_ALL_TESTS();
}

with the next team

g++ -lgtest -lgtest_main -lpthread test1.cpp 

to see another useless error message:

/usr/bin/ld: /tmp/ccQlmghI.o: undefined reference to symbol '_ZN7testing8internal9EqFailureEPKcS2_RKSsS4_b'
/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../../lib/libgtest.so: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

How can i fix this? Or is there another unittest framework that can be used SIMPLY, with a working example?

The same question is asked here , but without an answer.

Answer 1

g++ . ( ) .. GCC.

, :

g++ -Wall -g -pthread test1.cpp -lgtest_main  -lgtest -lpthread 

Answer 2

gtest gtest, , gtest ( , . ). ,

g++ -Wall -g -pthread test1.cpp -lgtest_main  -lgtest -lpthread

g++ -Wall -g  -pthread test1.cpp    /usr/lib/libgtest.a 

/usr/lib, , gtest, libgtest.a - .
