Build fils when compiling with MinGW #21

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Compile distorm using MinGW:

C:\Users\tantalum\Documents\Research\distorm>python setup.py build 
--compiler=mingw32

2. Watch the build fail because the wrong arguments are passed to gcc:
running custom_build
running build_py
creating build
creating build\lib
creating build\lib\distorm3
copying python\distorm3\sample.py -> build\lib\distorm3
copying python\distorm3\__init__.py -> build\lib\distorm3
running build_clib
running custom_build_clib
building 'distorm3' library
creating build\temp.win-amd64-2.7
creating build\temp.win-amd64-2.7\src
C:\strawberry\c\bin\gcc.exe -mno-cygwin -mdll -O -Wall -Isrc -Iinclude -c 
src\decoder.c -o build\temp.win-amd64-2.7\src\decoder.o /Ox /Ob1 /Oy ""/D 
WIN32"" ""/D _DLL"" ""/D LIBDISTORM"" ""/D SUPPORT_64BIT_OFFSET"" ""/D _MBCS""

gcc: /c: No such file or directory
gcc: /TC: No such file or directory
gcc: /Fdbuild\vc90.pdb: No such file or directory
error: command 'gcc' failed with exit status 1

What is the expected output? What do you see instead?
The expected outcome would be for the correct flags to be passed to gcc instead 
of just pretending that everything uses MSVC.

What version of the product are you using? On what operating system?
I'm using the svn HEAD version with Windows 7 on a 64-bit machine

So what's the core of the issue?
The problem lies in setup.py around line 180. The build selects the extra 
compiler flags depending on the operating system instead of the compiler being 
used. For windows the extra compiler flags are suitable for MSVC but cause gcc 
to fail.

    if 'windows' in system:
        libraries = [(
            'distorm3', dict(
            package='distorm3',
            sources=get_sources,
            include_dirs=['src', 'include'],
            extra_compile_args=['/Ox', '/Ob1', '/Oy', '"/D WIN32"',
                                '"/D _DLL"', '"/D LIBDISTORM"', '"/D SUPPORT_64BIT_OFFSET"',
                                '"/D _MBCS"', '/GF', '/Gm', '/Zi', '/EHsc',
                                '/MT', '/Gy', '/W4', '/nologo', '/c', '/TC',
                                '/Fdbuild\\vc90.pdb'],
            extra_link_args=['/MANIFEST']))]

Hey there,
thanks for the report.

Since I have never used MinGW before, I would appreciate further help here.
Can you try to compile it and give me the command line switches for the 
compiler?

I went through Microsofts documentation and came up with this summary of the 
args passed to MSVC:
/Ox -- Maximize Optimization
/Ob1 -- Expand only functions marked inline, enable inline expansion
/oy -- Omit frame pointer
/D WIN32 -- Declare WIN32
/D _DLL -- Declare _DLL
/D LIBDISTORM -- Declare LIBDISTORM
/D SUPPORT_64BIT_OFFSET
/D _MBCS 
/GF -- Remove Dulplicate Strings
/Gm -- Enable minimul rebuild
/Zi -- Generate debugging information
/EHsc -- Exception Handling: Catch C++ exceptions
/MT -- Use multithreaded staticly linked version of the standard library
/Gy -- Enable function level linking, automatically set by /Zi
/W4 -- Set warning level to 4
/nologo -- Duh!
/c -- Don't link
/TC -- Specify C source
/Fdbuild\\vc90.pdb --  Use the vc90 PDB file

I'v hacked the setup file to use these options instead of the MSVC options:
extra_compile_args=['-fPIC', '-O2', '-Wall',
                    '-DSUPPORT_64BIT_OFFSET', '-D_DLL',
                    '-DLIBDISTORM', '-DWIN32']))]

Building and installing with these options work.... but when you try to run the 
sample python complains that it can't load the dynamic lirary:
C:\Users\tantalum\Documents\Research\ian\distorm_test>python sample.py
Traceback (most recent call last):
  File "sample.py", line 6, in <module>
    import distorm3
  File "C:\Python27\lib\site-packages\distorm3\__init__.py", line 47, in <module>
    raise ImportError("Error loading the diStorm dynamic library")
ImportError: Error loading the diStorm dynamic library

I don't know what's causing this. Trying to link a C program also failes.
C:\Users\tantalum\Documents\Research\ian\distorm_test>gcc disassemble.c -o 
disassemble -ldistorm3 -L C:\Python27\Lib\site-packages\distorm3\
C:\Users\tantalum\AppData\Local\Temp\ccGvYPi3.o:disassemble.c:(.text+0x5a):

C:\Users\tantalum\AppData\Local\Temp\ccGvYPi3.o:disassemble.c:(.text+0x3fd): 
undefined reference to `distorm_decode64'
collect2: ld returned 1 exit status

To make things even more fun I decided to see what 'dumpbin /EXPORTS' had to 
say about distorm3.dll and distorm3.lib, and they both export distorm_decode64 
and distorm_version:

Any hints on how to move forward would be wonderful. I would very much like to 
see this working with mingw. Sorry if I miss something obvious, it's been a 
while since I worked with this kind of stuff on windows and you gotta love the 
way it 'keeps things orignized'.

Hey
I will check it out tomorrow and let you know.

From my test, I bet you compiled the extension as an x86 binary, and your 
Python is x64. Therefore you cannot load the DLL into the process, since it's 
incompatible. You will have to rebuild diStorm as x64 somehow. Or use Python 
for x86, err.
As for now it seems distutils still doesn't support MinGW well, and I'm not 
going to support it. Sorry.

FYI: I was able to make it working.
I installed MinGW64 from http://www.drangon.org/mingw
make sure you extract the file to c:\mingw
(rename the original 32bits version first, so not to override the files).
Or alternatively, you could set the path to the 64 bits version of gcc.exe of 
the new MinGW... probably doing that is smarter.

Then I tried to compile using: python setup.py --compiler=mingw32
(While having your patch to the setup.py file)
The build failed on the compilation of the .dll file itself, but the object 
files were compiled.
This is where I copy pasted that command line which failed and removed the part 
"-lmsvcr90" and re-ran that command line and it created the actual .dll file 
for x64. After that I copied that .dll to the site-packages\distorm3 and 
imported the distorm3 library in Python and it worked!

The command line I ran was:
c:\mingw\bin\gcc.exe -mno-cygwin -shared -s 
build\temp.win-amd64-2.7\src\decoder.o build\temp.win-amd64-2.7\src\distorm.o 
build\temp.win-amd64-2.7\src\instructions.o 
build\temp.win-amd64-2.7\src\insts.o build\temp.win-amd64-2.7\src\operands.o 
build\temp.win-amd64-2.7\src\prefix.o build\temp.win-amd64-2.7\src\textdefs.o 
build\temp.win-amd64-2.7\src\wstring.o build\temp.win-amd64-2.7\src\x86defs.o 
build\temp.win-amd64-2.7\include\mnemonics.o -lmsvcr90 -o 
build\lib\distorm3\distorm3.dll

Though it's possible on your env the files will be created in a different 
directory, but just so you get the idea.
Hope it solves your problem.
