因為zmq的原生配置rpath和gcc路徑一樣，無法滿足自定義目錄的gcc安裝環境，所以進行修改
1.解壓zmq原始碼，開啟檔案makefile.am，增加-wl,-rpath,'$$origin'，如下
if on_linux
libzmq_la_ldflags = \
-version-info @ltver@ \
@libzmq_extra_ldflags@ \
-wl,--version-script=$(srcdir)/src/libzmq.vers -wl,-rpath,'$$origin'
else
2.執行命令autoreconf，重新配置
3.執行編譯功能
./configure --with-libsodium=no && make clean && make
4.檢視rpath

編譯時斷言
執行時斷言大家都用過，但如果想當某個條件不滿足時在編譯時就讓程式編譯不通過，即編譯時斷言 不能產生 是什麼樣子的呢。可參考如下 1,參考linux核心靜態斷言 force a compilation error if condition is true ifdef win32 define buil...

編譯時的 warning
warning其實可以分為兩種 一種是可以忽略的，一種是不可以忽略的。比如 int被看作bool的warning往往是不能忽略的，而myclass 被轉換成int的warning都是可忽略的。pragma warning disable x 可以顯式的忽略那些確定不會造成惡劣影響的warning。比...
