OpenJDK7 のビルドが "./gamma: relocation error" というエラーで失敗する

Java

事象

OpenJDK7u40 をビルドすると "./gamma: relocation error: .../libjava.so: symbol JVM_FindClassFromCaller, version SUNWprivate_1.1 not defined in file libjvm.so with link time" というエラーで失敗する。

原因

  • OpenJDK 7 をビルドする際は ALT_BOOTDIR に JDK6u45 を指定する必要がある。

Download and install Oracle JDK 1.6.0_45 and set it to "ALT_BOOTDIR" and "ALT_JDK_IMPORT_PATH", please do not use OpenJDK1.6

java - Cannot compile openjdk7 source code on CentOS6.5 - Stack Overflow
  • JDK-8006965 の fix が含まれる JDK はビルドする のと同じバージョンを ALT_BOOTDIR 指定しても良くなっている模様。

Right now test_gamma runs with the boot JDK which is JDK n-1 (where JDK n is the version we are actually compiling for). This setup is unsupported and thus should not be done during HotSpot builds.

[JDK-8006965] remove test_gamma and add dedicated test_* targets instead - Java Bug System

対策

OpenJDK6u45 をインストールして環境変数 ALT_BOOTDIR にパスをセットしてからビルドする。

$ chmod +x jdk-6u45-linux-x64.bin
$ ./jdk-6u45-linux-x64.bin
  • OpenJDK7u40 をビルドする(ALT_BOOTDIR 以外の環境変数は上記と同じものを使う)
$ export ALT_BOOTDIR=/home/yazekats/Downloads/bin/jdk1.6.0_45
$ make
