Re: [Numpy-discussion] Installing numpy under cygwin
Thank you. This time the building of Numpy worked with no error message. However, when I now try to import Numpy in Python, there is a problem with lapack_lite (see below). Thanks again!

* A small module to implement missing C99 math capabilities required by numpy
*
* Please keep this independant of python ! Only basic types (npy_longdouble)
* can be used, otherwise, pure C, without any use of Python facilities
*
* How to add a function to this section
* -
*
* Say you want to add `foo`, these are the steps and the reasons for them.
*
* 1) Add foo to the appropriate list in the configuration system. The
*lists can be found in numpy/core/setup.py lines 63-105. Read the
*comments that come with them, they are very helpful.
*
* 2) The configuration system will define a macro HAVE_FOO if your function
*can be linked from the math library. The result can depend on the
*optimization flags as well as the compiler, so can't be known ahead of
*time. If the function can't be linked, then either it is absent, defined
*as a macro, or is an intrinsic (hardware) function.
*
*i) Undefine any possible macros:
*
*#ifdef foo
*#undef foo
*#endif
*
*ii) Avoid as much as possible to declare any function here. Declaring
*functions is not portable: some platforms define some function inline
*with a non standard identifier, for example, or may put another
*idendifier which changes the calling convention of the function. If you
*really have to, ALWAYS declare it for the one platform you are dealing
*with:
*
*Not ok:
*double exp(double a);
*
*Ok:
*#ifdef SYMBOL_DEFINED_WEIRD_PLATFORM
*double exp(double);

From the error, it looks like a C99-style // comment (which should not be there), but I don't see it in the last revision. Could you put the content of the file build/src.cygwin-1.5.25-i686-2.5/numpy/core/src/npy_math.c as well ? thanks, David ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
Re: [Numpy-discussion] Installing numpy under cygwin
The crt0.o file was indeed missing. I have reinstalled cygwin from the cygwin
setup.exe (as it seemed to be included therein), and it seems to have solved
that.
However, I now get the error below.
Thanks,
Olivia

The message is misleading (the message is hopefully improved with the
last trunk), and it is almost always caused by a broken toolchain
(that is you are missing gcc, or g++, etc...).
It would be helpful to have the full build log to help you better,

Re: [Numpy-discussion] Installing numpy under cygwin
Hello,
I attempted to install Numpy for my Cygwin python again, by simply executing:
>python setup.py install
However, I now get the following:
>File "numpy/core/setup.py", line 253, in check_mathlib
> raise EnvironmentError("math library missing; rerun "
>EnvironmentError: math library missing; rerun setup.py after setting the
MATHLIB
>env variable
I have a math library from cygwin (libm.a), but I have not managed to set it.
How should I set this?
Thank you for the help,
Olivia

For most purposes, cygwin works as unix. In particular, you don't think you should not use mingw32 build on cygwin. The -mno-cygwin flag appended to gcc is most likely coming from there, and this looks very wrong for a cygwin build.

[Numpy-discussion] Installing numpy under cygwin
Hello.
I am currently trying to install the latest version of NumPy for my cygwin
Python, and I am having problems...
I have downloaded the source, and unzipped and untarred it in my home directory.
Subsequently, I included the following in the site.cfg file:
>[DEFAULT]
>library_dirs = /cygdrive/c/cygwin/lib
>include_dirs = /cygdrive/c/cygwin/usr/local/include
>[blas_opt]
>libraries = f77blas, cblas, atlas
>[lapack_opt]
>libraries = lapack, f77blas, cblas, atlas
In the Cygwin bash shell, after going to my home directory, I have executed:
python setup.py config --compiler=mingw32 build --compiler=mingw32 install
as instructed in the "Installing SciPy/Windows" page.
The result is the following:
error: Command "gcc -mno-cygwin -mdll -O -Wall -Inumpy/core/include -Ibuild/src.
cygwin-1.5.25-i686-2.5/numpy/core/include/numpy -Inumpy/core/src -Inumpy/core/in
clude -I/usr/include/python2.5 -c build/src.cygwin-1.5.25-i686-2.5/numpy/core/sr
c/npy_math.c -o build/temp.cygwin-1.5.25-i686-2.5/build/src.cygwin-1.5.25-i686-2
.5/numpy/core/src/npy_math.o" failed with exit status 1
I have included below the complete output (and error) I get.
What could be the problem?
Thank you,
Olivia
