Hey, Thomas

Up to now, I have finished the first two steps. However, in the last step, that is "install CpyMAD", I got into trouble again.

According to the recommendation, I run the commands in CMD: python setup.py install --madxdir=<madx-install-path>.
i.e. D:\install\Windows-setup\pymad-cpymad-4cf406c>python setup.py install --madxdir=D: \install\Windows-setup\madX

And then, the error occurs: error: Unable to find vcvarsall.bat, as the troubleshooting mentioned.

Next, I run the commands on the command line: D:\install\Windows-setup\pymad-cpymad-4cf406c>python setup.py build --madxdir=D:\install\Windows-setup\madX --compiler=mingw32 as recommended in the Troubleshooting.
I don't use the first method, which needs to add another lines to the C:\python27\Lib\distutils\distutils.cfg, since I can't find out distutils.cfg everywhere in my computer.

After that, an error occurs again, saying as below:

D:\install\Windows-setup\pymad-cpymad-4cf406c>python setup.py build --madxdir=D:

B.t.w, the built versions seems to be invalid. when I click on the link it says Not found.

Hey,

I encountered this problem once before, but not with the compiler suite installed by python-xy, which is why I didnt include in the documentation. I will update the docs accordingly.

The fix is as follows: In the file C:\Python27\Lib\distutils\cygwinccompiler.py delete every occurence of the string -mno-cygwin in the class Mingw32CCompiler (about line120):

EDIT: oops wrong line number. Real line number is about 320!

Depending on your version on distutils, for example:

@@ -319,11 +319,11 @@ class Mingw32CCompiler (CygwinCCompiler):
         else:
             entry_point = ''

or

        if self.gcc_version < '4' or is_cygwingcc():

        else:
            no_cygwin = ''

Furthermore, I noticed that you substituted <madx-install-dir> = D: \install\Windows-setup\madX. However, you need to use the path as specified by -DCMAKE_INSTALL_PREFIX. I.e. if you followed the recommendations, it should be:

python setup.py install --madxdir=D: \install\Windows-setup\madX\install --compiler=mingw32

Hope this helps. Thomas.

I don't use the first method, which needs to add another lines to the C:\python27\Lib\distutils\distutils.cfg, since I can't find out distutils.cfg everywhere in my computer.

If it doesn't exist, you need to create the file distutils.cfg in the folder C:\Python27\Lib\distutils or wherever you installed your python to.

Hey, Thomas
I don't know how to modify my distutils, whch is different from yours. Sorry, I know little about this. Below is my distutils, containg class Mingw32CCompiler only.

# class CygwinCCompiler


# the same as cygwin plus some additional parameters

        CygwinCCompiler.__init__ (self, verbose, dry_run, force)

        # ld_version >= "2.13" support -shared so use it instead of

Did you try to replace the line that reads:

           no_cygwin = ' -mno-cygwin'

by

           no_cygwin = ''

as suggested by the second diff in my post before?

BTW: I have now updated the install recommendations to be more thorough about the points where you had problems so far.

commented

Yes, I replace it as you do, but the error still exists.
command 'gcc' failed with exit status 1

commented

Still with the

gcc: error: unrecognized command line option '-mno-cygwin'

error?

Can you open the enhanced terminal and execute python, then:

>>> import sys
>>> print(sys.executable)

And send me the output?

commented

BTW, do you have jabber/IM for faster communication?

sorry I don't know jabber.

commented

This is a different error, meaning the first problem is fixed. It indicates that either the <madx-install-path> you used is incorrect or the make install command from the build libmadx step did not succeed.

In #76 you posted install log according to which you should substitute --madxdir="D:\install\Windows setup\madX.r4920\install". Please check that the path from the argument exists and contains subfolders include, bin, lib.

To speed things up, you should always try to check whether my answers fix your original error and then post updated information, so I don't need to ask whether you really got the same message again.

commented

OK, I will check the path and try it again. thank for your attention!

Great. Keep in mind, that this package is still in development, and if you have questions or suggestions, just go ahead and open an issue;).
