上一篇中，提示找不到NICE库，先看看CMakList里面吧
[root@localhost erizo]# pwd /home/test/licode-master/erizo [root@localhost erizo]# vim src/CMakeLists.txt #global variable set(THIRD_PARTY_INCLUDE "${CMAKE_CURRENT_SOURCE_DIR}/../../build/libdeps/build/include/") set(THIRD_PARTY_LIB "${CMAKE_CURRENT_SOURCE_DIR}/../../build/libdeps/build/lib/") ## Depencencies # GLIB find_package(Glib REQUIRED) include_directories(${GLIB_INCLUDE_DIRS}) # BOOST set (BOOST_LIBS thread regex system) find_package(Boost COMPONENTS ${BOOST_LIBS} REQUIRED) # GTHREAD find_library(GTHREAD gthread-2.0 HINTS "${THIRD_PARTY_LIB}") test_lib(${GTHREAD}) # SRTP find_library(SRTP srtp2 HINTS "${THIRD_PARTY_LIB}") test_lib(${SRTP}) # NICE find_library(NICE nice HINTS "${THIRD_PARTY_LIB}") test_lib(${NICE})
看来"${CMAKE_CURRENT_SOURCE_DIR}/../../build/libdeps/build/lib/里面没有nice库
进到目录：
[root@localhost libdeps]# ls build libav-11.9 libnice-0.1.4 libnice-0.1.4.tar.gz libsrtp-2.1.0 libsrtp-2.1.0.tar.gz nvm openssl-1.0.2p openssl-1.0.2p.tar.gz opus-1.1.tar.gz v11.9.tar.gz [root@localhost libdeps]# pwd /home/test/licode-master/build/libdeps [root@localhost libdeps]# ls build/lib/ engines/ libcrypto.a libsrtp2.a libssl.a pkgconfig/
确实是没有nice库，但是nice已经下载了，只是没有编译，对nice进行编译

make错误，得先解决一下这个符号错误，看看53行
[root@localhost libnice-0.1.4]# vim examples/threaded-example.c
static GMutex gather_mutex, negotiate_mutex; static GCond gather_cond, negotiate_cond;
很简单的定义代码，但是说不认识这个结构，令人费解了
看看GMutex定义，看看有没有结构吧
[root@localhost libnice-0.1.4]# vim /usr/include/glib-2.0/glib/gthread.h typedef struct _GMutex GMutex; typedef struct _GCond GCond; typedef struct _GPrivate GPrivate; typedef struct _GStaticPrivate GStaticPrivate; typedef struct _GThreadFunctions GThreadFunctions; struct _GThreadFunctions { GMutex* (*mutex_new) (void); void (*mutex_lock) (GMutex *mutex); gboolean (*mutex_trylock) (GMutex *mutex); void (*mutex_unlock) (GMutex *mutex); void (*mutex_free) (GMutex *mutex); GCond* (*cond_new) (void); void (*cond_signal) (GCond *cond); void (*cond_broadcast) (GCond *cond); void (*cond_wait) (GCond *cond, GMutex *mutex); gboolean (*cond_timed_wait) (GCond *cond, GMutex *mutex, GTimeVal *end_time); void (*cond_free) (GCond *cond); GPrivate* (*private_new) (GDestroyNotify destructor); gpointer (*private_get) (GPrivate *private_key); void (*private_set) (GPrivate *private_key, gpointer data); void (*thread_create) (GThreadFunc func, gpointer data, gulong stack_size, gboolean joinable, gboolean bound, GThreadPriority priority, gpointer thread, GError **error); void (*thread_yield) (void); void (*thread_join) (gpointer thread); void (*thread_exit) (void); void (*thread_set_priority)(gpointer thread, GThreadPriority priority); void (*thread_self) (gpointer thread); gboolean (*thread_equal) (gpointer thread1, gpointer thread2); }; GLIB_VAR GThreadFunctions g_thread_functions_for_glib_use; GLIB_VAR gboolean g_thread_use_default_impl; GLIB_VAR gboolean g_threads_got_initialized;
看这个样子，是这个版本的glib并不支持GMutex结构体，而改为函数调用，并且提供默认管理以及外部处理管理。
目前我们只需要让example编译通过，直接使用默认的即可。
将threaded_example.c修改为：

修改的主要部分为：不使用GMutex，GCond变量，改为指针，在main函数开始时进行初始化。
执行make，还有example错误，使用相同的方式进行修改

log4cxx安装成功
[root@localhost erizo]# pwd /home/test/licode-master/erizo [root@localhost erizo]# ./generateProject.sh
执行成功，之后就需要编译了

天啊，这可真是一个大问题了，竟然遇到了gcc版本过低的问题，看来得先考虑升级gcc的版本了
https://ftp.gnu.org/gnu/gcc/ 在里面下载版本下载gcc4.8.5，当然下载其他的也可以
[root@localhost gcc-4.8.5]# pwd /home/test/log4cxx/gcc-4.8.5 [root@localhost gcc-4.8.5]# yum install gmp-devel [root@localhost gcc-4.8.5]# yum install mpfr-devel [root@localhost gcc-4.8.5]# yum install libmpc-devel [root@localhost gcc-4.8.5]# ./configure [root@localhost gcc-4.8.5]# make In file included from /usr/include/features.h:385:0, from /usr/include/stdio.h:28, from ../../.././libgcc/../gcc/tsystem.h:87, from ../../.././libgcc/libgcc2.c:27: /usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file or directory # include <gnu/stubs-32.h>
看来gcc的编译里面还有些事儿，下一篇再继续吧
