編譯安裝 zbar 時兩次 make 帶來的驚喜

為了裝 php 的條形碼擴展模塊 php-zbarcode，先裝了一天的 ImageMagick 和 zbar。也許和我裝的 Ubuntu 17.10 的有版本相容問題吧，總之什麼毛病都有，apt 不行，PPA 源也不行，編譯安裝還有幾處源代碼出錯，裝不上～折騰了大半天之後終於把 ImageMag ...

為了裝 php 的條形碼擴展模塊 php-zbarcode，先裝了一天的 ImageMagick 和 zbar。也許和我裝的 Ubuntu 17.10 的有版本相容問題吧，總之什麼毛病都有，apt 不行，PPA 源也不行，編譯安裝還有幾處源代碼出錯，裝不上～

折騰了大半天之後終於把 ImageMagick 編譯安裝好了～～而在編譯安裝 zbar 的時候，值得微笑的事就來了。參考了網上的很多資料，解決了大多問題，比較重要的是在 zbar 執行 ./configure 配置的時候會找不到 ./wand/ 目錄下的頭文件，加兩個軟鏈接指向本地庫就可以

sudo ln -s /usr/local/include/ImageMagick-7 /usr/local/include/ImageMagick
sudo ln -s /usr/local/include/ImageMagick-7/MagickWand /usr/local/include/wand

最後剩下一個，就是在 make 編譯的時候始終報錯，錯的地方有點多～～

谷歌翻遍了，結果只有純文本格式的 log 日誌，這我還是第一次見到～～直到晚上，我放棄了谷歌。回到源頭，在嘗試改了幾處錯誤後，我懵了～～百思不得其姐，這搞不下去了。然後我清掉了整個編譯目錄，重新解了 zbar 的 tar.gz 包。重來。

執行了 ./configure，然後抱著撞大運的態度執行了 make。不出所料，還是那好長一串串的錯誤消息。心累……

我盯著屏幕發了會兒呆，手也不自覺地又敲了個 m、a、k、e，回車——

----------------------------------------------------------------------
Libraries have been installed in:
   /usr/local/lib

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.

(⊙v⊙)嗯，用 zbar 的命令行介面 zbarimg ，試一下我剛做的二維碼電子名片

完全可以。總之，裝上了。

不過這兩次 make 其中的道理還是不太明白的，就留待以後了，有時間再系統整理一下編譯時候的一些簡單原理，暫且這麼記下～
