原因：libphenom.pc 被复制到了/usr/local/lib/pkgconfig/ 目录， 实际起作用的是 /usr/lib64/pkgconfig
解决办法:\cp /usr/local/lib/pkgconfig/libphenom.pc /usr/lib64/pkgconfig
错误3
编译：
gcc -O2 main.c `pkg-config libphenom --cflags --libs`
[root@s3 libphenom-master]# ./a.out
./a.out: error while loading shared libraries: libphenom.so.0: cannot open shared object file: No such file or directory
原因：共享库文件安装到了/usr/local/lib(很多开源的共享库都会安装到该目录下)或其它"非/lib或/usr/lib"目录下。
解决办法:
# echo "/usr/local/lib" >> /etc/ld.so.conf
# ldconfig
------------------------------------------------------------------------------------------------------------------------------------------------------------
// Always include phenom/defs.h first to correctly set up the compilation env
#include "phenom/defs.h"

#include "phenom/job.h"
#include "phenom/log.h"
#include "phenom/sysutil.h"
int main(int argc, char **argv)
{
// Must be called prior to calling any other phenom functions
ph_library_init();
// Optional config file for tuning internals

// Enable the non-blocking IO manager

// Do stuff here to register client/server stuff.
// This enables a very simple request/response console

// `echo memory | nc -UC /tmp/phenom-debug-console`
// (on BSD systems, use `nc -Uc`!)
// The code behind this is in
// https://github.com/facebook/libphenom/blob/master/corelib/debug_console.c

// Run
ph_sched_run();
