今天安装 CUnit，发现几个坑，在此记一下。

首先下载 CUnit： http://cunit.sourceforge.net/

安装过程：

tar jxvf CUnit-2.1-3.tar.bz2
cd CUnit-2.1-3
./bootstrap
./configure
make
make install

cc -o tests/build-tests tests/httptest.c
/tmp/ccl6l4rB.o: In function `test1‘:
httptest.c:(.text+0x3b): undefined reference to `CU_assertImplementation‘
/tmp/ccl6l4rB.o: In function `test2‘:
httptest.c:(.text+0x66): undefined reference to `CU_assertImplementation‘
/tmp/ccl6l4rB.o: In function `main‘:

httptest.c:(.text+0x102): undefined reference to `CU_basic_set_mode‘
httptest.c:(.text+0x107): undefined reference to `CU_basic_run_tests‘
httptest.c:(.text+0x10c): undefined reference to `CU_cleanup_registry‘
httptest.c:(.text+0x111): undefined reference to `CU_get_error‘
collect2: ld returned 1 exit status
make: *** [build-tests] Error 1

在编译的时候加 -lcunit 就可以了，例如我的makefile: 

build-tests : tests/httptest.o
	cc -o tests/build-tests tests/httptest.c -lcunit
tests/httptest.o : tests/httptest.c

test : build-tests
	tests/build-tests

./build-tests: error while loading shared libraries: libcunit.so.1: cannot open shared ob

sudo ln -s /usr/local/lib/libcunit.so.1 libcunit.so.1
