我试图在我的一个项目中使用gtest，并且我使用scons构建了gtest，并且我能够在库链接路径中看到库文件。但是，当我在测试中使用库时，我收到链接器错误。
这是scons文件：
#!/usr/bin/env python
import os
Import('envGlobal')
env = envGlobal.Clone()
envGlobal.Append(CPPPATH=[os.path.abspath('../include')])
files = env.Glob('*.cpp')
print(env['LIBPATH']) #I see libgoogletest.a here
env.Append(LIBS=['tasking','googlemock','googletest','pthread','rt'])
program = env.Program(target = 'OSRAGenerationCode_Refactored_test', source = files)
installTest = env.Install(envGlobal['BINPATH'],program)
envGlobal.Alias('install', installTest)
我收到以下错误：
