Error: command 'gcc' failed with exit status 1

Hello,

i am installing CVXOPT using the instructions of this site "abel.ee.ucla.edu/cvxopt/install/index.html"

When i reach "python setup.py build --compiler=mingw32" i face the following problem

C:\Python27\cvxopt-1.1.5\src>python setup.py build --compiler=mingw32

Can u please help?

Your compiler cannot find for inclusion these files which should be part of the compiler distribution:

stdarg.h
stddef.h

I usually doubt the advice when told to "reinstall my xxx". Sorry. Reinstalling your mingw compiler might solve the problem.

Otherwise, you need to find the files on your computer system and somehow pass options through setup.py .

I'm certain that, were I using your computer directly, I could finish this build. It would be messy because I've never figured out setup.py.


stddef.h is in some directory. Let's call the directory

c:/Program Files/mingw/gcc/include

You need to pass the argument

-I"c:/Program Files/mingw/gcc/include"

to gcc.

stddef.h and stdarg.h are probably in the same directory.


Alternatively, you could copy those files into
C:\Python27\cvxopt-1.1.5\src\include\

and run the build command you first tried.


I expect you'll have more issues before this is finished.
