[Latex][chapterbib]

耗了兩天，所以特地寫了篇心得文之類的？

Anyway，有時，像是在寫書時，會想要在各章後放各章的參考文獻，但是一般來說參考文獻都會被放在文件的最後面，如果想要在各章之後 show 出來的話該怎麼做呢？這時就要用 chapterbib 這個 package 了。

底下是我這次所測試出來可以用的例子。

Example/
  |-article.tex
  |-Chap01/
      |-reference.bib
      |-section01.tex
      |-section02.tex
  |-chap01.tex
  |-Chap02/
      |-reference.bib
      |-section01.tex
      |-section02.tex
  |-chap02.tex
  |-Makefile

[article.tex]
\documentclass{book}                   
\usepackage[sectionbib]{chapterbib}
\usepackage{CJKutf8}
\begin{document}
    \begin{CJK*}{UTF8}{bkai}
        \include{chap01} 
        \include{chap02}
    \end{CJK*}
\end{document}

[chap01.tex]
\chapter{Chapter 01}
    \input Chap01/section01.tex
    \input Chap01/section02.tex
    \newpage
    \bibliographystyle{plain}
    \bibliography{Chap01/reference.bib}


[chap02.tex]
\chapter{Chapter 02}
    \input Chap02/section01.tex
    \input Chap02/section02.tex
    \newpage
    \bibliographystyle{plain}
    \bibliography{Chap02/reference.bib}

[Makefile]
all:
    latex article
    bibtex chap01
    bibtex chap02
    latex article
    latex article
    pdflatex article

clean:
    rm -rf *.aux *.bbl *.blg *.dvi *.log *.pdf

如果不加上 sectionbib 的話，就會是在文件最後面才會依章列出所用的參考文獻。

[GCC][Create and Use Shared Library]

This is only the record of the content of the book I read.

gcc -fPIC -c initapi.c
gcc -fPIC -c randapi.c

gcc -shared initapi.o randapi.o -o libmyrand.so

gcc main.c -L. -lmyrand -o main

export LD_LIBRARY_PATH=./

If we wanted to load this shared library dynamically.

cp libmyrand.so /usr/local/lib
