我试图在我的Ubuntu机器上设置GTest环境.但在使GTest获取库时,我收到以下错误...

Program("xtest", Split("main.cpp"), LIBS="mylib fltk Xft Xinerama Xext X11 m")
我如何让scons使用mylib.a而不是mylib.so,同时动态链接其他库？
编辑:希望尽可能少使用平台特定的黑客.
来自http://www.adp-gmbh.ch/cpp/gcc/create_lib.html:
注意:库必须以三个字母开头
lib并具有后缀.a.
这是一个操作系统约定,还是gcc/ arquirk？Xcode似乎能够创建没有前缀的库.它有什么不同的做法？
我正在关注这本书。
我安装了 GoogleTest 并构建了库：
kuyu@ub16:~/Downloads/googletest-master$ find . -name *.a
./mybuild/googlemock/libgmock_main.a
./mybuild/googlemock/gtest/libgtest_main.a
./mybuild/googlemock/gtest/libgtest.a
./mybuild/googlemock/libgmock.a
我有一个 CMakeLists.txt 文件：
kuyu@ub16:~/Downloads/lotdd-code/c2/2$ echo $GMOCK_HOME
/home/kuyu/Downloads/googletest-master
kuyu@ub16:~/Downloads/lotdd-code/c2/2$ cat CMakeLists.txt
project(chapterFirstExample)
cmake_minimum_required(VERSION 2.6)
include_directories($ENV{GMOCK_HOME}/googlemock/include $ENV{GMOCK_HOME}/googletest/include)
link_directories($ENV{GMOCK_HOME}/mybuild/googlemock $ENV{GMOCK_HOME}/mybuild/googlemock/gtest)
add_definitions(-std=c++0x)
set(CMAKE_CXX_FLAGS "${CMAXE_CXX_FLAGS} -Wall")
set(sources
main.cpp
SoundexTest.cpp)
add_executable(test ${sources})
target_link_libraries(test pthread)
target_link_libraries(test gmock)
target_link_libraries(test gtest)
然后我尝试构建我的源文件：
kuyu@ub16:~/Downloads/lotdd-code/c2/2$ mkdir build && cd build
kuyu@ub16:~/Downloads/lotdd-code/c2/2/build$ cmake ..
# output omitted for brevity...
kuyu@ub16:~/Downloads/lotdd-code/c2/2/build$ make
