CgiCc 使用
一、下載下傳
下載下傳位址：
http://ftp.gnu.org/gnu/cgicc/
ftp://ftp.gnu.org/gnu/cgicc/ 二、配置、編譯、安裝
- 下載下傳完成後解壓：
shell tar xzf cgicc-X.X.X.tar.gz
- 進入解壓的目錄：
`
- 配置
./configure --prefix=/opt --prefix 參數指定安裝目錄，預設安裝目錄為/usr
- 編譯
make - 安裝
make install 三、例程
3.1 如果在64bit平台編譯32位庫：
CXXFLAGS="-m32" CFLAGS="-m32" LDFLAGS="-m32" 3.2 如果安裝目錄為/opt：
- 編譯時指定包含路徑：
shell -I/opt/include
- 編譯時指定引用路徑：
shell -L/opt/lib

3.5 編譯c++ CGI demo
- 使用靜态庫編譯
如果安裝在/opt/：
g++ -o testcgi.cgi -I/opt/include testcgi.cpp /opt/lib/libcgicc.a
如果安裝在/usr/：
g++ -o testcgi.cgi testcgi.cpp /usr/lib/libcgicc.a
- 使用動态庫編譯
g++ -o testcgi.cgi -I/opt/include testcgi.cpp -L/opt/lib -lcgicc
g++ -o testcgi.cgi testcgi.cpp -lcgicc
3.6 運作
- 将
testcgi.html
/var/www/html/
-
testcgi.cgi
/var/www/cgi-bin/
- 本機測試 :
http://127.0.0.1/testcgi.html
