Question about GNU Fortran 77 compiler

[Hanks]

Hello All,

Now I am compiling GNURadio 3.2 directly on beagleboard. However, I
can't pass ./configure with the following error

------------------------
checking whether we are using the GNU Fortran 77 compiler... no
......

checking for Python include path... /usr/include/python2.6
checking Python.h usability... no
checking Python.h presence... yes
configure: WARNING: Python.h: present but cannot be compiled
configure: WARNING: Python.h: check for missing prerequisite
headers?
configure: WARNING: Python.h: see the Autoconf documentation
configure: WARNING: Python.h: section "Present But Cannot Be
Compiled"
configure: WARNING: Python.h: proceeding with the compiler's result
checking for Python.h... no
configure: error: cannot find usable Python headers
------------------------

But I do have python and python-devel installed.

I checked online, it's said the reason is that configure need GNU
Fortran 77 to check Python. But there is no g77.ipk from
http://www.angstrom-distribution.org/feeds/unstable/ipk/glibc/armv7a/base/

So how to install GNU Fortran 77 for Angstrom/OE?

Thanks

Zhen

I just installed 'arm-angstrom-linux-gnueabi-gfortran' and created a
link file 'g77' to get GNU Fortran 77 worked

But I still get the above "Python.h" error.

---------------------

checking for Python include path... /usr/include/python2.6
checking Python.h usability... no
checking Python.h presence... yes
configure: WARNING: Python.h: present but cannot be compiled
configure: WARNING: Python.h: check for missing prerequisite

configure: WARNING: Python.h: see the Autoconf documentation
configure: WARNING: Python.h: section "Present But Cannot Be

configure: WARNING: Python.h: proceeding with the compiler's result
checking for Python.h... no
configure: error: cannot find usable Python headers
-------------------

Did anybody meet the similar problem and solve it?

Thanks a lot!

This is usually a sign of requiring the Python development package.  Install python-dev

Thanks

However, I have installed the Python development package "python-
deval", and there exists python include dir at /usr/include/
python2.6.

So is there any other reasons for this problem?

And btw, what's the difference between python-dev and python-devel
package?

Did you try looking at the 'config.log' file (generated in the directory
where 'configure' is being run)? It should tell you more about why
this is failing.

Thanks your suggestion. I checked config.log and got the following
error info on f77 -c -g O2 conftest.f

It seems autoconf generates the "test for Python.h" using C-code but
tries to compile it using a Fortran compiler.

From http://www.mail-archive.com/discuss-...@gnu.org/msg25448.html,
I solved it by changing "config/gr_python.m4"
