Here with python 2.7.13 and Visual Studio 2013, I get hit by the problem and it 
looks like link.exe needs the /MANIFEST keyword. Voting to get it fixed!

[issue4431] Distutils MSVC doesn't create manifest file

[Steve Dower]

Steve Dower added the comment:

It shouldn't be necessary for VS 2010 and later, and the 
`extra_link_args=['/MANIFEST']` workaround should be sufficient for cases where 
it is necessary (specific dependencies other than MSVCRT that require 
manifests).

And I suspect Matthew Brett's issue is that link_executable() does not expect

[issue4431] Distutils MSVC doesn't create manifest file

[Steve Dower]

Steve Dower added the comment:

/MANIFEST is probably assumed on VC9 since the CRT required it, but that was 
probably changed for VC10 without updating the documentation fully. Frankly I'd 
rather remove the MANIFESTFILE property added by distutils, since it doesn't 
add anything of value (on my test machine, it only requests an execution level 
of asInvoker, which is the default).

That way people can include useful manifests with their source if necessary and 
provide both the /MANIFEST and /MANIFESTFILE flags themselves, and we reduce 
the amount of code in the stdlib.

[Matthew Brett]

Matthew Brett added the comment:

I think the argument previously was that VS 2010 was not the default compiler 
for Python 2.7, and so this problem was not important, but I'm happy to be 
corrected.

I haven't tried building extensions for Python 2.7 with VS 2010 but I guess the 
problem will be the same.

Can you see a problem with adding the /MANIFEST flag to 
distutils/msvc9compiler.py as a fix for this problem?

Just to be clear, I ran into this exact issue recently in VS2010 professional

[issue4431] Distutils MSVC doesn't create manifest file

[Steve Dower]

Steve Dower added the comment:

Sorry, I was focused on the fact that you don't need a manifest with VS 2010 
and not that distutils was forcing you to have one when building an executable.

Either adding '/MANIFEST' as in paxan's patch (according to 
http://msdn.microsoft.com/en-us/library/fft52235.aspx, you need to specify it 
if you specify '/MANIFESTNAME') or removing the MANIFESTNAME specification 
entirely should be fine for 3.4 and later. I assume since nobody has complained 
about 2.7 that everything works fine there?

[Matthew Brett]

Matthew Brett added the comment:

Steve - did you try my 'setup.py' example; it's standalone, as in `python 
setup.py build` will reproduce the error.

This is specifically VS 2010.

It doesn't make any difference for me if I specify an extension or not, so I 
don't think that is the problem.

[issue4431] Distutils MSVC doesn't create manifest file

[Matthew Brett]

Matthew Brett added the comment:

I think this is a frank bug for Pythons that use MSVC 10+ by default (3.3, 3.4 
for example).

The lack of the /MANIFEST flag breaks the 
distutils.ccompiler.CCompiler.link_executable command - see attached setup.py 
example.  The example gives the error main.exe.exe.manifest : general error 
c1010070: Failed to load and parse the manifest. The system cannot find the 
file specified.

We (http://nipy.org/dipy) ran into this because we were innocently using 
compilation of a 'main.c' file to an executable to check link flags.

[issue4431] Distutils MSVC doesn't create manifest file

[Stephen Hansen]

Stephen Hansen added the comment:

FYI. Windows 8.1, Visual Studio 2010 SP1 Pro just installed, Python 3.3.3; a 
random extension did this as a 'test' in its setup.py:

compiler = distutils.ccompiler.new_compiler()
if not compiler.has_function('rand', includes = ['stdlib.h']):
...

And this failed. Further investigation turned brought me here, and adding 
/MANIFEST to my ld_args as this patch does fixed it.

[Sébastien Sablé]

Sébastien Sablé sa...@users.sourceforge.net added the comment:

I need Python compiled with Visual Studio 2010 because I use it embedded in an 
application compiled with Visual Studio 2010.

I am pretty sure there are quite a lot of people who would like to compile 
Python with this compiler.

I have compiled Python 2.7.2 with this version of the compiler as well as many 
extensions, but this required to patch quite a few things. I also intend to 
setup a buildbot running Python tests using this compiler.

If I can provide the patch to support Visual Studio 2010 and setup a builtbot 
that will pass most of the tests, could we get Python supported on this 
platform?

I intended to announce all of that on python-dev soon, but the buildbot is not 
quite ready yet.

Yes. Even if VS2008 remains the preferred compiler to build Python, and the 
only one used for official binary distributions, there are already project 
files for VS8 and even VC6 (in PC/VS8.0 and PC/VC6).  They are not guaranteed 
to always work, but are updated from time to time by volunteers.
Please open another issue.

[Mark Hammond]

Mark Hammond skippy.hamm...@gmail.com added the comment:

I don't think a buildbot will be necessary - like the earlier compilers, they 
may have basic support but they don't all get buildbot support.  The problem 
isn't the lack of ability/will to get things working with VS2010 - it is more 
the lack of incentive to add another compiler to the mix.  OTOH, seeing it is 
nearly 2012, a case could certainly be made to move 3.3 to that compiler :)

I'm interested to see the patch required to get it working - almost every other 
upgrade has been almost handled completely by the VS upgrade process so it 
would be good to see how different this one is - so please CC me on any new 
issue you create.

I'm also interested to know how mixing the CRTs is causing problems - are you 
using the very few Python APIs impacted by such mixing, or is the issue more 
about needing to redistribute both, or something else entirely?

Amaury:
Great! I have opened issue 13210 to achieve that.

Mark:
Mixing the 2 CRTs results in plenty of crashes in our application. The 
application also uses a lot of Qt. It is not an option to use a prebuilt Python 
binary generated with VS2008.

I added you to issue 13210 and I will post the patches there soon.

[issue4431] Distutils MSVC doesn't create manifest file

[Mark Hammond]

Mark Hammond skippy.hamm...@gmail.com added the comment:

My experience is that for VS2008 at least, the /MANIFESTFILE: option seems to 
be ignored if there is nothing to put in the manifest, and this tends to be 
true if you use a static CRT instead of the DLL based one (ie, if you use /MT)

Issue 7833 has a patch designed to both (a) remove the manifest entirely if the 
only assembly reference is to the CRT and (b) give the setup.py author finer 
control over this behaviour.

David Schnur dnsch...@gmail.com added the comment:

I haven't commented since opening this issue, but I've been following along.  
Regarding Marc-Andre's latest comment, I think whether to embed a manifest or 
not is a separate issue.  The current behavior is to embed a manifest, and so 
it should ensure that the file is created.  As others have said, given that 
distutils expects /MANIFEST implicitly, there seems no harm in adding it 
explicitly.

I agree that this issue should be re-opened, since it's apparently not 
restricted just to my case of using /MT.

I encountered the same problem while compiling the psutil package.

I used Python 3.2.2 that I compiled myself using Visual Studio 2010 SP1 in 
Debug mode by following the PCBuild/readme.txt documentation.

I could not compile psutil until I added in setup.py:
extra_link_args=['/MANIFEST']

I have not tried to compile any other C extension yet, but this is not 
mysql-python and I am not using setuptools either.

Hi Marc,

Well, I fried my original server install trying to trace this.  My new fresh 
install can still reproduce the problem with mysql-python, but I can't recreate 
the issue with PyOpenSSL anymore.  Grabbing packages at random from PyPi hasn't 
given me a single issue so far, so I'm going to say this is an issue with 
mysql-python only and redirect my efforts there.

Thanks for your help,

Hi David,

since both you and Pavel are building mysql-python and using
setuptools (which applies a lot of hacks on stock distutils),
could you please also try some other package from PyPI in that
same configuration and preferably one which doesn't rely on
setuptools ?

Adding the switch per default will probably not cause much harm,
except when you explicitly don't want the manifest to be created
and added to the DLL (which is needed in some situations as as well).

Thanks,

Are you sure ?

We've had such a request before and the reason for MSVC not generating
a .manifest file was some setting the user had done on his system.

FWIW: distutils generates those files just fine for me.

Then again, it probably doesn't hurt just adding the option.

[issue4431] Distutils MSVC doesn't create manifest file (with fix)

[Pavel Repin]

Pavel Repin prepin+pythonb...@gmail.com added the comment:

Hi Marc,I am pretty sure it helped on my particular configuration.
I was trying to compile MySQL-python-1.2.2.tar.gz package from source and it
was failing in mt.exe step because the manifest file was not there.
I didn't do anything special on my machine. I have 3 versions of MSVS
installed cleanly side-by-side (which is a legit scenario): MSVS 2003, MSVS
2005, and MSVS 2008. All at the latest patch levels. No standalone
PlatformSDKs are installed.

Besides, if you just ignore the obscure blurb about /MANIFEST option being
default in MSDN, and read the descriptions of both /MANIFEST and
/MANIFESTFILE options, you would agree that it will not do any harm to be
explicit and always have /MANIFEST option passed to linker.

I'm going to do one more experiment with a different machine, this time it
will be Vista (not W7) with a similar MSVS setup. I will report my findings.

  for 80x86

 Are you sure ?

 We've had such a request before and the reason for MSVC not generating
 a .manifest file was some setting the user had done on his system.

 FWIW: distutils generates those files just fine for me.

 Then again, it probably doesn't hurt just adding the option.

[issue4431] Distutils MSVC doesn't create manifest file (with fix)

[Pavel Repin]

Pavel Repin prepin+pythonb...@gmail.com added the comment:

Marc-Andre,
I can also repro this on Vista machine with the same Python  MSVS
configuration.
This is the build error stemming from missing manifest file
(unnecessary details elided; note the absence of /MANIFEST option):

find the file specified.

The error goes away when I hack msvc9compiler.py to have:
ld_args.append('/MANIFEST')

See patch attached to the bug.

[issue4431] Distutils MSVC doesn't create manifest file (with fix)

[David Schnur]

New submission from David Schnur [EMAIL PROTECTED]:

This is my first time submitting an issue; sorry if I am doing this 
wrong.  While attempting to build/install PyOpenSSL on Windows / MSVC, 
the mt.exe step failed because it could not find the manifest file that 
it was attempting to embed in crypto.pyd.  The problem was that link.exe 
was not creating the manifest.

The reason why is that distutils only passes link.exe the 
/MANIFESTFILE:filename parameter.  This tells it where to output the 
manifest, but not to actually create the manifest (see 
http://msdn.microsoft.com/en-us/library/fft52235(VS.80).aspx).  You'd 
think link could figure out that, if you use /MANIFESTFILE, you want a 
manifest, but I guess not ;)

My solution was to add this line to distutils/msvc9compiler.py:

ld_args.append('/MANIFEST')

Right beneath the existing line:

ld_args.append('/MANIFESTFILE:' + temp_manifest)

Hope that helps

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc [EMAIL PROTECTED] added the comment:

Since issue4120, the compilation tools precisely chose to *not* embed 
manifests in .pyd extensions.
This probably means that the mt.exe step should be skipped by 
distutils.

I'm not sure whether that's necessary. We are building pyOpenSSL
just fine against stock Python 2.6.0 in our distribution:

http://www.egenix.com/products/python/pyOpenSSL/

and even though the command line does not include the /MANIFEST
switch, the linker does builds the .manifest file just fine.

OTOH, it probably doesn't hurt adding the switch :-)

This is why we don't see the problem:

http://msdn.microsoft.com/en-us/library/f2c0w594.aspx


The default is /MANIFEST.


So it appears that you must have disabled this default somehow.

[David Schnur]

David Schnur [EMAIL PROTECTED] added the comment:

I looked at this some more (I'm not super familiar with the use of
manifests) and I think I figured it out.  For somewhat complicated
reasons, I'm compiling with /MT rather than /MD.  Although link normally
produces a manifest, since it's unnecessary when compiling static, it
isn't created unless you specify /MANIFEST.

So I suppose the issue is that distutils is trying to embed the manifest
in cases where it may legitimately not exist.  Since /MT is not the
default (I had to make that change explicitly), this is probably not a bug.
