Hello everybody,

With the same build/compile command, I'm able to have "my" runing python version (2.6.x or 2.7.x) on IA64 server runing SLES 10 SP2/SP3,not on IA64 server runing SLES 11 SP1. I've try with 2.7, 2.7.1 and 2.7.2rc1 version without success.

On both configuration types, I've installed all the available libraries, but on SLES 11 SP1, the make resulting message is the following (the complete building messages are in the joined gzip text file):

------------------
...
Python build finished, but the necessary bits to build these modules were not found:
_bsddb _sqlite3 _ssl
_tkinter bsddb185 bz2
dl imageop readline
sunaudiodev zlib
To find the necessary bits, look in setup.py in detect_modules() for the module's name.

Failed to build these modules:
_curses_panel

running build_scripts
------------------

Any advice will be welcome.

Thanks a lot for your attention and your process.

All the best,

Vincent

panel.h is not found. You'll need to install the package that
provides libpanel together with the header files:

error: panel.h: No such file or directory

This does not look like a Python bug, so I'll set the issue to
'pending'. You can still respond to the issue if you think otherwise.

vclaudic · 2011-06-06T18:24:37Z

Hello Stefan,

Thanks a lot for your time and answer, but here are some additional information regarding the requires "panel.h" file. I've just launched a find command onto my ia64 server, and here is the result:

hesione:/ # find / -name "panel.h"
/usr/include/ncurses/panel.h
/usr/include/ncurses6/ncurses/panel.h
/usr/include/ncurses6/ncursesw/panel.h
/usr/include/ncursesw/panel.h
/usr/src/linux-2.6.32.12-0.7-obj/ia64/default/include/config/panel.h

As you may have also observed, the build command is claiming also ncurses, which is installed.

hesione:~ # rpm -qa|grep ncurses
yast2-ncurses-pkg-2.17.16-0.1.77
libncurses6-5.6-90.55
ncurses-devel-5.6-90.55
libncurses5-5.6-90.55
yast2-ncurses-2.17.17-0.4.38
ncurses-utils-5.6-90.55
libncurses5-x86-5.6-90.55
libncurses6-x86-5.6-90.55

Any further information will be welcome.

Thanks again for your patience, time and answer.

All the best,

Vincent

I just stumbled upon the same problem with Python 2.7.3 on SLES 11 SP1 amd64.

Obviously, SuSE puts the needed header file into /usr/include/ncurses/, and one can either create a symlink in /usr/include/ or apply a patch to _curses_panel.c:

--- Modules/_curses_panel.c.orig        2012-05-23 13:34:17.000000000 +0200
+++ Modules/_curses_panel.c     2012-05-23 13:34:27.000000000 +0200
@@ -14,7 +14,7 @@
 
 #include "py_curses.h"
 
-#include <panel.h>
+#include <ncurses/panel.h>
 
 static PyObject *PyCursesError;

Maybe some logic could be put into the build process to automatically handle this? Apparently, configure already knows about the different locations...

Regards,
Holger

The same happens on OpenSUSE 12.1 so Python can't be fully built there which is a bit of a shame.

OpenSUSE uses this patch for their packages, but that would break other distributions so it's not a good solution:
-#include <panel.h>
+#include <ncurses/panel.h>

Here's a list of all curses related files in /usr/include on my OpenSUSE 12.1:

If we look just for panel.h we get:
catalin@linux-vo6z:~/cpython/issue12271> find /usr/include/ -regex '.*curses.*' -and \( -type f -or -type l \) -exec ls -lh {} \; | grep panel.h

-rw-r--r-- 1 root root 4.0K Oct 29 2011 /usr/include/ncursesw/panel.h

There is some specific code that appends '/usr/include/ncursesw' to the include list in setup.py but that doesn't get triggered here because curses_library == 'ncurses' because readline is built against that.

The attached patch makes it build and the curses tests pass but it feels kind of hack-ish. panel.h is there so Python should find it somehow therefore this is a genuine bug. Ideas for a better solution?

KennethOBrien · 2013-03-27T13:59:57Z

I have created a simple patch that solves this problem. Depending on whether panel.h or ncurses/panel.h are found, the appropriate one is included.

KennethOBrien · 2013-03-30T00:23:04Z

Removed generated files from patch. Requesting review.

doko42 · 2013-03-30T14:59:26Z

hard coding ncurses seems to be wrong, as in most cases, you do want ncursesw.

fbauzac · 2019-10-11T10:39:30Z

I have been hit by the same issue today.
Kenneth's patch seems fine. Why not integrate it?

RazerM · 2023-11-30T10:47:44Z

This seems not so easily patched for Python 3.12

The configure script uses pkg-config, but only if it finds panel.h, even though pkg-config would help find where panel.h actually is:

$ pkg-config --libs --cflags ncursesw
-D_GNU_SOURCE -D_DEFAULT_SOURCE -I/usr/include/ncursesw -lncursesw -ltinfo
$ pkg-config --libs --cflags ncurses
-D_GNU_SOURCE -D_DEFAULT_SOURCE -I/usr/include/ncurses -lncurses -ltinfo
$ pkg-config --libs --cflags panel
-D_GNU_SOURCE -D_DEFAULT_SOURCE -D_GNU_SOURCE -D_DEFAULT_SOURCE -I/usr/include/ncurses -lpanel
$ pkg-config --libs --cflags panelw
-D_GNU_SOURCE -D_DEFAULT_SOURCE -D_GNU_SOURCE -D_DEFAULT_SOURCE -I/usr/include/ncursesw -lpanelw

RazerM · 2023-11-30T11:27:35Z

I suggest to use the tool pkgconf with

> ncurses6-config --cflags
-D_DEFAULT_SOURCE -D_XOPEN_SOURCE=600 -I/usr/include/ncurses
> pkgconf --cflags ncursesw
-D_DEFAULT_SOURCE -D_XOPEN_SOURCE=600 -I/usr/include/ncursesw

or specially for libpanel or libpanelw

>pkgconf --cflags panel
-D_DEFAULT_SOURCE -D_XOPEN_SOURCE=600 -I/usr/include/ncurses 
> pkgconf --cflags panelw
-D_DEFAULT_SOURCE -D_XOPEN_SOURCE=600 -I/usr/include/ncursesw

or for forms

> pkgconf --cflags form
-D_DEFAULT_SOURCE -D_XOPEN_SOURCE=600 -I/usr/include/ncurses 
> pkgconf --cflags formw
-D_DEFAULT_SOURCE -D_XOPEN_SOURCE=600 -I/usr/include/ncursesw

Yes, this seems non-optimal. I think we should run the pkg-config check for panel/panelw before we try to find panel.h.

I think we should run the pkg-config check for panel/panelw before we try to find panel.h.

Shouldn’t the logic be just other way around? We test for pkg-config provided configuration and only then we can try some hard-written values, whether they could work?

Unfortunately Python 3.6 doesn't include all autoconfig infrastructure required for the upstream solution, so we have to directly patch Modules/_curses_panel.c Discussion still continue on gh#python#56480.

Just to help any SUSE users who are still having this problem...

I noticed it today and after reading the installation documentation and having a chat with Google Gemini :-) we came up with the following workaround:

setting the CPPFLAGS parameter to "-I/usr/include/ncurses" before executing "configure"

and the ncurses library was found correctly.

This is a useful workaround until a more permanent change is decided upon.

Use the tool pkgconf(1) ... e.g. pkgconf --cflags ncursesw pkgconf --libs ncursesw to get CFLAGS for compiling as well as LIBS for linkage of the wide character version of (lib)ncurses. Beside pkg-conf there is also the script ncursesw6-config(1) which is also part of the package ncurses-devel
