bad reloc address 0x0 when compiling hsdis (Java HotSpot disassembler plugin) on cygwin

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

I followed this accepted answer.

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

First I tried to just compile it using:

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

but it failed with

/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.

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

The compilation failed again

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
^

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

Then the error is

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.

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

Solution

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

    Then open Makefile in editor, find rule:

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

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

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