如何在 Windows Netbeans 中设置 gtest？
我查看了 Netbeans 论坛、gtest wiki 和在这里&我似乎找不到让 gtest 在 Netbeans（6.9.1，Windows 7x64）中正常工作的方法。我的 gtest.h 的 #include 或 unittest 文件本身没有问题 - ASSERT_LE 被识别等。我正在使用 cygwin &结果与 c:\gtest-1.5.0 或 cygwin/usr/local/gtest-1.5.0 中的 gtest 相同。我认为可能需要为测试使用不同的 makefile 来使用 &基于 gtest 包含的 makefile，但这对我不起作用（也许我做错了）。这就是我按下 ALT-F6（测试项目）时得到的结果：
g++.exe -o build/Debug/Cygwin-Windows/tests/TestFiles/f1 build/Debug/Cygwin-Windows/tests/tests/Armor_unittest.o build/Debug/Cygwin-Windows/tests/tests/newsimpletest.o build/Debug/Cygwin-Windows/main_nomain.o build/Debug/Cygwin-Windows/Character_nomain.o build/Debug/Cygwin-Windows/Map_nomain.o build/Debug/Cygwin-Windows/Armor_nomain.o build/Debug/Cygwin-Windows/Weapon_nomain.o build/Debug/Cygwin-Windows/Shop_nomain.o build/Debug/Cygwin-Windows/Enemy_nomain.o
build/Debug/Cygwin-Windows/tests/tests/Armor_unittest.o: In function `_ZN31ArmorTest_SetupAndGetWorks_Test8TestBodyEv':
/cygdrive/c/Users/.../winPro2Game/tests/Armor_unittest.cpp:9: undefined reference to `testing::internal::AssertHelper::AssertHelper(testing::TestPartResult::Type, char const*, int, char const*)'
/cygdrive/c/Users/.../winPro2Game/tests/Armor_unittest.cpp:9: undefined reference to `testing::internal::AssertHelper::operator=(testing::Message const&) const'
/cygdrive/c/Users/.../winPro2Game/tests/Armor_unittest.cpp:9: undefined reference to `testing::internal::AssertHelper::~AssertHelper()'
/cygdrive/c/Users/.../winPro2Game/tests/Armor_unittest.cpp:9: undefined reference to `testing::internal::AssertHelper::~AssertHelper()'
等等...
如果我将一个与 gtest 中包含的文件几乎相同的自定义生成文件放入测试文件夹中，右键单击它&让我得到：
Makefile:21: target `gtest-all.o' doesn't match the target pattern
Makefile:25: target `gtest_main.o' doesn't match the target pattern
Makefile:39: *** multiple target patterns. Stop.
如果我再次进行测试项目，我得到：
rm -f build/Debug/Cygwin-Windows/tests/tests/Makefile.o.d
g++.exe -c -g -I../../../../../../../gtest-1.5.0/include -MMD -MP -MF build/Debug/Cygwin-Windows/tests/tests/Makefile.o.d -o build/Debug/Cygwin-Windows/tests/tests/Makefile.o tests/Makefile
g++: tests/Makefile: linker input file unused because linking not done

谢谢！
I've looked at the Netbeans forums, gtest wiki & around here & I can't seem to find a way to get gtest working right in Netbeans (6.9.1, Windows 7x64). There's no problem with my #include of gtest.h or with the unittest file itself - ASSERT_LE is recognized etc. I'm using cygwin & the results are the same with gtest at c:\gtest-1.5.0 or cygwin/usr/local/gtest-1.5.0. I think it might be matter of getting a different makefile for the tests to use & based off the gtest included makefile, but that hasn't worked for me (maybe I'm doing it wrong). This is what I get when I hit ALT-F6 (Test Project):
g++.exe -o build/Debug/Cygwin-Windows/tests/TestFiles/f1 build/Debug/Cygwin-Windows/tests/tests/Armor_unittest.o build/Debug/Cygwin-Windows/tests/tests/newsimpletest.o build/Debug/Cygwin-Windows/main_nomain.o build/Debug/Cygwin-Windows/Character_nomain.o build/Debug/Cygwin-Windows/Map_nomain.o build/Debug/Cygwin-Windows/Armor_nomain.o build/Debug/Cygwin-Windows/Weapon_nomain.o build/Debug/Cygwin-Windows/Shop_nomain.o build/Debug/Cygwin-Windows/Enemy_nomain.o
build/Debug/Cygwin-Windows/tests/tests/Armor_unittest.o: In function `_ZN31ArmorTest_SetupAndGetWorks_Test8TestBodyEv':
/cygdrive/c/Users/.../winPro2Game/tests/Armor_unittest.cpp:9: undefined reference to `testing::internal::AssertHelper::AssertHelper(testing::TestPartResult::Type, char const*, int, char const*)'
/cygdrive/c/Users/.../winPro2Game/tests/Armor_unittest.cpp:9: undefined reference to `testing::internal::AssertHelper::operator=(testing::Message const&) const'
/cygdrive/c/Users/.../winPro2Game/tests/Armor_unittest.cpp:9: undefined reference to `testing::internal::AssertHelper::~AssertHelper()'
/cygdrive/c/Users/.../winPro2Game/tests/Armor_unittest.cpp:9: undefined reference to `testing::internal::AssertHelper::~AssertHelper()'
etc...
If I put a custom built makefile that is almost identical to the one included with gtest into the test folder & right click on it & Make I get:
Makefile:21: target `gtest-all.o' doesn't match the target pattern
Makefile:25: target `gtest_main.o' doesn't match the target pattern
Makefile:39: *** multiple target patterns. Stop.
If I do Test Project again I get:
rm -f build/Debug/Cygwin-Windows/tests/tests/Makefile.o.d
g++.exe -c -g -I../../../../../../../gtest-1.5.0/include -MMD -MP -MF build/Debug/Cygwin-Windows/tests/tests/Makefile.o.d -o build/Debug/Cygwin-Windows/tests/tests/Makefile.o tests/Makefile
g++: tests/Makefile: linker input file unused because linking not done
gcc.exe build/Debug/Cygwin-Windows/tests/tests/Makefile.o -o build/Debug/Cygwin-Windows/tests/tests/Makefile
gcc: build/Debug/Cygwin-Windows/tests/tests/Makefile.o: No such file or directory
gcc: no input files
make[1]: *** [build/Debug/Cygwin-Windows/tests/tests/Makefile] Error 1

你一开始就很接近 - 从“未定义引用”的第一个片段开始，这是一个链接器配置问题 - 你没有添加 gtest 库。据我记得，gtest 不提供二进制文件，因此您必须自己编译库（gtest.lib），然后将其添加到链接器属性中的某个位置作为附加库 - 我自己不是 netbeans 用户，无法准确说出在哪里。
you were close in the first place - from the first snippet of "undefined reference", it's a linker configuration issue - you don't have gtest library added. as far as i remember, gtest doesn't ship binaries, so you'll have to compile library yourself (gtest.lib), then add that somewhere in linker properties as additional library - not a netbeans user myself, can't tell exactly where.
