在cygwin上编译hsdis（Java HotSpot反汇编插件）时，错误的reloc地址0x0 [英] bad reloc address 0x0 when compiling hsdis (Java HotSpot disassembler plugin) on cygwin

问题描述

我试图编译JVM需要反汇编JIT编译代码的 hsdis-amd64.dll 库。

I'm trying to compile the hsdis-amd64.dll library that the JVM needs to disassemble JIT compiled code.

我遵循此接受的答案。

• 我安装了cygwin


• 已下载 openjdk-7u40-fcs-src-b43-26_aug_2013.zip


• 并下载了 binutils-2.24.tar.gz

• I installed cygwin
• downloaded openjdk-7u40-fcs-src-b43-26_aug_2013.zip
• and downloaded binutils-2.24.tar.gz

我创建了一个这样的文件夹结构：

I created a folder structure like this:

+
+- hsdis             // unzipped dir hotspot/src/share/tools/hsdis of openjdk zip
+- binutils-2.24     // unzipped binutils-2.24.tar.gz

首先我试图使用：

$ make OS=Linux MINGW=x86_64-w64-mingw32 BINUTILS=../binutils-2.24

但是失败了

/Linux-amd64/opcodes/libopcodes.a build/Linux-amd64/libiberty/libiberty.a
hsdis.c:32:20: fatal error: sysdep.h: No such file or directory
#include <sysdep.h>
                ^
compilation terminated.

所以我应用了接受答案并再次尝试。

So I applied the patch provided in this accepted answer and tried again.

失败了

In file included from hsdis.c:34:0:
build/Linux-amd64/bfd/bfd.h:35:2: error: #error config.h must be included before this header
#error config.h must be included before this header
^

我按照编译器的建议，在 config.h c $ c> errno.h include。

I followed the proposal of the compiler and added config.h just before the errno.h include.

然后错误是

collect2: error: ld returned 1 exit status

我知道这是一个链接器问题。对我来说，它似乎是试图链接到一个错误的版本，但我可能是错误的。

I know that it is a linker problem. For me it seems that it is trying to link against a wrong version, but I might be wrong.

有人知道如何解决这个问题或可以告诉我如何编译hsdis（HotSpot反汇编插件）？

Does anyone knows how to solve this problem or can tell me how to compile the hsdis (HotSpot disassembler plugin)?

推荐答案

需要添加对zlib的链接（确保安装包mingw64 -x86_64-zlib in cygwin）。

There is need to add linking against zlib (Be sure that you install package mingw64-x86_64-zlib in cygwin).

在编辑器中打开Makefile，找到规则：

Open Makefile in editor, find rule:

$(TARGET): $(SOURCE) $(LIBS) $(LIBRARIES) $(TARGET_DIR)
    $(CC) $(OUTFLAGS) $(CPPFLAGS) $(CFLAGS) $(SOURCE) $(DLDFLAGS) $(LIBRARIES)

将-static -lz添加到第二行，以便：

Add "-static -lz" to second line to make that:

$(TARGET): $(SOURCE) $(LIBS) $(LIBRARIES) $(TARGET_DIR)
    $(CC) $(OUTFLAGS) $(CPPFLAGS) $(CFLAGS) $(SOURCE) $(DLDFLAGS) $(LIBRARIES) -static -lz
