Run the following command:

Mkdir-p/usr/local/include/freetype2/freetype/internal

Reinstall

4. install ant

The version used this time is: apache-ant-1.9.4-bin.zip

Unzip apache-ant-1.9.4-bin.zip

Ln-s decompressed ant directory/bin/ant/usr/bin/ant

 

5. install JDK and configure environment variables

The next compilation is openjdk-7-fcs-src-b147-27_jun_2011.zip, which requires jdk 6u14 or later. the JDK installation method is not written here.

6. download and decompress openjdk

The use of openjdk version: openjdk-7-fcs-src-b147-27_jun_2011.zip

After the download is complete decompress it: unzip openjdk-7-fcs-src-b147-27_jun_2011.zip

After decompression, an openjdk folder will be created.

7. check whether jdk is successfully installed.

Java-version: successful if the Echo contains the installed JDK details

Ant if the Echo contains build. xml does not exist! The installation is successful.

8. set environment variables before compilation

Unset CLASSPATH
Unset JAVA_HOME
Export LANG = C
Export ALT_BOOTDIR = the complete jdk installation directory, for example,/home/wyh/study/java/jdk.
Export ANT_HOME = complete ant installation path, for example,/home/wyh/study/apache-ant-1.9.4/
Export ALT_FREETYPE_LIB_PATH =/usr/local/lib
Export SKIP_DEBUG_BUILD = false
Export SKIP_FASTDEBUG_BUILD = true
Export DEBUG_NAME = debug
Export ALT_FREETYPE_HEADERS_PATH =/usr/local/include/freetype2

IX. Pre-compilation check

Switch to the decompressed openjdk path and execute: make sanity

If the following Echo is displayed, the check is successful:

........................................ ..........................

Previous JDK Settings:

Previus_release_path = USING-PREVIOUS_RELEASE_IMAGE

Alt_previus_release_path =

PREVIOUS_JDK_VERSION = 1.6.0

Alt_previus_jdk_version =

PREVIOUS_JDK_FILE =

Alt_previus_jdk_file =

PREVIOUS_JRE_FILE =

Alt_previus_jre_file =

PREVIOUS_RELEASE_IMAGE =/home/wyh/study/java/jdk

Alt_previus_release_image =

Sanity check passed.

 

10. Compile

Command: make all ARCH_DATA_MODEL = 64 ALLOW_DOWNLOADS = true, long time

If the following Echo is displayed, the compilation is complete:

 

11. test the self-compiled JDK

./Build/linux-amd64/bin/java-version

If the following Echo is displayed, the compilation is successful:
