Cygwin encountered an error installing an answer.

It seems that the installation of pycrypto is out of order.

/usr/include/sys/time.h

by adding u_int to be redefined in the Installation is complete.

vi/usr/include/sys/time.h

#ifndefu_int
typedef unsigned intu_int;
#endif

The answer is, "What's that good?" But I've built a pycrypto in cygwin before, so I looked it up.
It may be unnecessary as it seems to have already been resolved, but I will post it to share information.

When I build the source of pycrypto-2.6.1, I get the same error.
(cygwin was updated the other day)

$python setup.py build

I don't think there was any problem when I installed the same version about a year ago...

As far as the error is concerned, it seemed to be a python problem in cygwin rather than a python problem, so I looked it up a little bit, but when I built the python expansion module,

  • Include a standard library header before "Python.h".
  • Added "-std=c99" option

It appears that an error occurs if the condition is present.

$cathoge.c
# include <string.h>
# include <Python.h>

$ gcc-choge.c-std=c99`python-config --cflags`

It seems to have already been resolved, but it's a little uncomfortable to fiddle with the header of the system, so I'll make other suggestions.

Cygwin has a package called python-crypto, so install it from setup.exe.

However, there seems to be no package for python3.
(I think that's why I built and installed it myself in the past.)

Download and deploy the source code for pycrypto-2.6.1 and comment out as there is an option for "-std=c99" around line 118 of "setup.py".

 if self.compiler.compiler_type in ('unix', 'cygwin', 'mingw32'):
            # Tell GCC to compile using the C99 standard.
            #self.__add_compiler_option("-std=c99")#Comment here

Install.

python setup.py install

Now I think I can install it.(I only built it myself)
