Hey,

Has anyone compiled python 2.7 using LTIB for imx35?

I have attached the spec file

These are the errors I get:

In file included from Include/Python.h:58,

                 from ./Modules/python.c:3:

make: *** [Modules/python.o] Error 1

I used the build commands spec file from this link

Re: [Ltib] Building Python 2.7

 

I don't understand if this error is related to the python source or the arm tools used by ltib. Can someone please help?

Has anyone compiled python successfully? if so, what am I doing wrong?

Thanks Leonardo,

Unfortunately that did not work.

I made an interesting observation tho. I looked at the output of the ./configure scripts that created the makefiles.

checking size of size_t... 4

checking size of pid_t... 4

checking for long long support... yes

checking size of long long... 8

checking for long double support... yes

So if it does have support for long long, y doesn't it compile??

Hi Neeraj,

http://www.cnx-software.com/2011/02/04/cross-compiling-python-for-mips-and-arm-platforms/

I think you are not the only one with this issue, but there is patch to solve it. Pyhon on LTIB is on rpm/BUILD/<python> so apply the patch from that folder.

Hi Leonardo,

Thanks for the link.

I got sidetracked on other projects and wasnt able to follow up.

After using the patch I dont get the PY_FORMAT_LONG_LONG error any more.

However,

I get a ton of warning messages and python builds but with some key modules missing.

You are compiling python with ltib, right? something like './ltib -p python -scbuild' ? Seems that the header files are being taken from the host filesystem, instead of the ltib filesystem..

Yes I am using ./ltib -p Python-2.7.1.spec -m scbuild

Attaching the spec file. I have changed the spec file after going thru some of the above links.

What am I doing wrong here?

Hi neo1, could you please generate a patch instead of the whole .spec? try this

$ cd <original spec folder>

$ git init

$ git add *.spec

$ git commit -m 'first commit'

$ # do your changes here

$ git commit -a -m 'changes'

$ git format-patch -1

then send me the generated .patch file please.
