今天在 Redhad 6.6 上遇到問題，會有類似這樣的錯誤。
/tmp/cc2QQ7Ek.s:778709: Error: no such instruction: shlx %rdx,%rsi,%rdx'
/tmp/cc2QQ7Ek.s:779180: Error: no such instruction: shlx %rsi,%r10,%rsi’

/tmp/cc2QQ7Ek.s:811422: Error: no such instruction: shlx %rdx,%rcx,%rdx’
/tmp/cc2QQ7Ek.s:814194: Error: no such instruction: shlx %rdx,%rsi,%rdx'
/tmp/cc2QQ7Ek.s:830004: Error: no such instruction: shlx %rdx,%rsi,%rdx’
推測是 gcc 抓錯設定(因為上頭已經先安裝其他 library)，所以改成自己 make。
在 ubuntu 之外的系統都要自己先 git clone 後下指令做編譯與安裝(official ref)，指令只是很簡單的
git clone --depth=1 "git://github.com/phalcon/cphalcon.git"
cd cphalcon/build
sudo ./install
但因為 gcc 有問題，所以要改成先切換到指定的 php 版本與作業系統路徑，然後下 make 與 make install，改用cc做。

----------------------------------------------------------------------
Libraries have been installed in:
/var/www/cphalcon/build/php7/64bits/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Build complete.
Don't forget to run 'make test'.
