#51695: could not use setup.py to install pyraf using the macports installation of python 2.7 -------------------------------+-------------------------------- Reporter: mahajan.smriti@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Resolution: | Keywords: Port: | -------------------------------+-------------------------------- Old description:

I have installed python 2.7 using macports and it seemed to work fine untill I had to install Pyraf. Amongst others the last bit of the installation code read:

warning: manifest_maker: standard file '-c' not found

The C compiler used to compile Python gcc-4.2, and which is normally used to compile C extensions, is not available. You can explicitly specify which compiler to use by setting the CC environment variable, for example:

CC=gcc python setup.py <command>

or if you are using MacOS X, you can try:

CC=clang python setup.py <command>

---------------------------------------- Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/zt/rfcx53ks5b7_1_773_2jwpp80000gn/T/pip-build- ImCNyh/astropy

Now I do have gcc installed, so I tried looking for setup.py and I think the one installed with Macports version of Python on my laptop is in /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/python /py-entrypoints/files/

but when I try running python /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/python /py-entrypoints/files/setup.py install

I get

running install running build running build_py creating build error: could not create 'build': Permission denied

Not sure how to use setup.py to install Pyraf or for that matter other modules. I am using Python 2.7 on Mac OS X 10.9.5

I am using Python 2.7 on Mac OS X 10.9.5 -- Comment (by ryandesign@…): The message stating that Python was compiled with gcc-4.2 is strange. That would not be the case on OS X 10.9.5. OS X 10.6.8 was the last OS X version to feature gcc-4.2. Are you sure you are running MacPorts python? What version of Xcode do you have installed? Don't try to directly run files inside the MacPorts ports tree; they're not for you; they're for MacPorts to use when installing ports. Each Python module or project will typically include its own setup.py file tailored to that project's needs; that's the setup.py you'll be using to build that project.

I have Xcode version 5.1.1 installed.

Ok, good, that's a supported version for OS X 10.9. You could update to as new a version as 6.2 if you wanted to.

Also which gcc returns /usr/bin/gcc.

That is normal. You should find that if you run `gcc --version`, it informs you that it is not in fact gcc but actually clang.

I am sure I am using the Macports python, because I have explicitly set the path to it in the .profile file using alias python='/opt/local/bin/python2.7'. I have to admit though that I do have other installations of Python 2.7 on my laptop, which perhaps came in bundled with other packages I installed earlier, but I do not know how to get rid of them to clean up the system.

Ok. Instead of setting an alias in your .profile, you could instead use `sudo port select python python27`.

I tried using CC=clang python setup.py pip install pyraf

but that returns

{{{

/opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python: can't open file 'setup.py': [Errno 2] No such file or directory

}}}

This means there is no file called setup.py in the current directory.

Not sure though why it is searching for setup.py in the /Frameworks/.. directory tree, when I have specified which Python I want to use.

It's not searching for setup.py in the /Frameworks/.. directory tree. Rather, /opt/local/bin/python2.7 is a symlink to /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python. So python is merely printing its full path for you. It looks like you're getting confused about how to install python modules. You can either download the source code and run the setup.py file contained therein, or you can use pip to install it for you; you don't do both.
