Hey Asma,
Thank you Andi for your suggestions, but I do not think that my shell is
broken I am using the GNU bash, version 3.2.19(2)-release
(i586-mandriva-linux-gnu)
Yes, I now don't think that the shell is broken either.
[charfi@is010178 ~]$ sh -version
GNU bash, version 3.2.19(2)-release (i586-mandriva-linux-gnu)
Copyright (C) 2005 Free Software Foundation, Inc.
I created the 2 scripts as you suggest, and executed first.sh, I get this:
[charfi@is010178 ~]$ ./first.sh
START
SECOND
END SECOND
AFTER GCC
Okay, this approach was just too simple ...
I really need to add a front end to GCC.
And I would really be glad to help and assist you, but it currently
seems to me that the problem is specific to your machine only and that
it would be generally hard to find it.
However, maybe some of the suggestions/suspicions help:
* you mentioned that the config-lang.in file from the C++ front-end
works without any problems even though both files, from the C++
front-end and the sample_fe front-end "look" equal. But maybe, something
went wrong during the download or extraction of the archive (just for
the case, here's a checksum of the file using the cksum utility
sample_fe config-lang.in
1684117529 427 config-lang.in
* alternatively (a bit more time-consuming), you could try to copy the
config-lang.in from the C++ front-end to the sample_fe directory and
successively change this file back to the contents of the sample_fe
config-lang.in while checking which change really makes the problems
* if that all doesn't help, you could try to follow the suggestion of
Philip to use his code for the python front-end with gcc-4.5.0
Best regards,
Andi
Have you any idea ?
thank you very much
Asma

First of all, I have no idea what's wrong, because I've never seen this
error before. Well, all these mentioned lines are empty lines in the
config-lang.in and it seems that the configure script or better your
shell tries to execute these empty lines when the config-lang.in file
gets included into the configure script.
Just like I said, I tested the sample_fe front-end with my (x)ubuntu
system in bootstrap mode, and I didn't face any problems.
For me it seems - without any proof - that your POSIX shell (/bin/sh)
is somehow broken. Which version of /bin/sh are you using? Because I
don't have a Mandriva 2009 system by hand, I can't try to reproduce, but
just for the case that you want to dig further into the problem, you
could have a look into the configure script at lines 5066-5277.
But, maybe as a first start, you could create two shell scripts with the
following contents. They should try to reproduce your phenomenon:
===== first.sh =====
#!/bin/sh
echo "START"
value=
. ./second.sh
echo "AFTER ${value}"
===== END first.sh
===== second.sh =====
echo "SECOND"
value=GCC
echo "END SECOND"
===== END second.sh =====
After creating these two files, keep the file permissions of second.sh
at 644 and change the file permissions for first.sh to 755 and finally
execute
# ./first.sh
START
SECOND
END SECOND
AFTER GCC
Maybe someone else on this list has an idea what could be wrong or has
already seen this error before ...
Andi
