在使用php處理一些圖像時(shí)，有時(shí)會(huì)出現(xiàn)諸如這樣的錯(cuò)誤：Call to undefined function imagecreate()

這是由于沒(méi)有安裝或是沒(méi)有開(kāi)啟php的gd庫(kù)導(dǎo)致的問(wèn)題。

常規(guī)Ubuntu與windows

解決方案：

一、在Linux系統(tǒng)（這里用的是Ubuntu系統(tǒng)）下

首先在終端輸入下列命令：

sudo apt-get install php5-gd

這樣就已經(jīng)安裝完php的gd庫(kù)了。如果使用的是apache服務(wù)器，這時(shí)還需重啟下服務(wù)器：

sudo service apache2 restart

如果是nginx則可用可不用。

二、在windows系統(tǒng)下

打開(kāi)php安裝目錄下的php.ini配置文件，找到這一行：

;extension=php_gd2.dll

將這一行前面的;號(hào)去掉，然后保存。這樣已經(jīng)開(kāi)啟了gd擴(kuò)展庫(kù)。

最后重啟下服務(wù)器就行了。

編譯make安裝方法

在編譯配置擴(kuò)展的時(shí)候就沒(méi)加上gd的同學(xué)可以參考下面的方法

找到安裝php的目錄下，重新配置擴(kuò)展

make clean
./configure --prefix=/png/php/5.6.40 --enable-fpm --with-apxs2=/usr/bin/apxs2 --enable-maintainer-zts -with-mysqli --with-pdo-mysql --with-pdo-sqlite --with-gd
make
make test
make install

./configure --with-gd有了就行，其他的擴(kuò)展看需求

vim打開(kāi)php.ini

搜索

#vim命令關(guān)鍵字搜索： (1) 點(diǎn)ESC （2）/“關(guān)鍵字”

/extension=php_gd2.dll

找到這行去掉前面的分號(hào)“；”

保存退出，重啟nginx，apache2重啟apache2

/etc/init.d/httpd restart

index.php查找gd,,,成功！

phpize方法

原因：未安裝php的gd庫(kù)，主要處理圖片的庫(kù)

解決方法：

在已經(jīng)安裝php的情況先，需要對(duì)PHP進(jìn)行擴(kuò)展，加入gd庫(kù)

1:進(jìn)入到php源碼里面的gd目錄下

cd /usr/src/php-5.5.38/ext/gd/

2：執(zhí)行phpize (命令在php/bin/目錄下)

phpize

3：編譯安裝

./configure --with-php-config=/usr/local/php5/bin/php-config --with-png-dir --with-freetype-dir --with-jpeg-dir --with-gd
make
make install

會(huì)報(bào)錯(cuò)，執(zhí)行下面命令：

yum install libpng
yum install libpng-devel
yum install freetype-devel

此時(shí)安裝完成后會(huì)生成一個(gè)gd.so的文件，記住這個(gè)路徑

ls /usr/local/php5/lib/php/extensions/no-debug-non-zts-20121212/
curl.so gd.so opcache.so pcntl.so pdo_mysql.so

4：修改php的配置文件php.ini將gd.so的路徑加入進(jìn)去，如下加入到最后面就行

vim /usr/local/php5/php.ini
[root@slb03 ~]# tail -1 /usr/local/php5/php.ini
extension=/usr/local/php5/lib/php/extensions/no-debug-non-zts-20121212/gd.so

5：重啟apache服務(wù)

/etc/init.d/httpd restart

centos安裝GD庫(kù)

采用phpize的方式安裝，也不成功

提示Cannot find config.m4.

[root@hotdata gd]# php -i | grep -i --color gd
PWD => /usr/include/php/ext/gd
_SERVER["PWD"] => /usr/include/php/ext/gd

直接使用yum命令安裝不成功，錯(cuò)誤信息如下：
主要提示信息為需要安裝依賴包，可是我已經(jīng)安裝了

 You could try using --skip-broken to work around the problem
