Re: Help needed: build failure trying to upgrade healpix

[Jarryd Lisher via devel <devel@xxxxxxxxxxxxxxxxxxxxxxx>]

Hey,

 

I figured out that this is mainly caused by the configure script containing multi-line definitions. So, the hacks only operate on the first part and land up leaving random lines of nonsense in the file.

 

You can fix this by adding the following "unwrap" `sed` script just before the `%{configure}` line:

```

%{__sed} -i -z -e 's/\\\n//g' configure

```

It's not perfect, but is a simple fix to remove those errors from the configure.

What I see is that the hacks that you apply to configure are apparently not
working:

checking command to parse /usr/bin/nm -B output from gcc object...
./configure: line 7304: -e 's/^T .* \(.*\)$/extern int \1();/p' -e
's/^[ABCDGIRSTW][ABCDGIRSTW]* .* \(.*\)$/extern char \1;/p': No such file or
directory

It is possible that that is what is causing the:
checking for ffgnrwll in -lcfitsio... no
configure: error: could not find the cfitsio library
failure in the C++ part's configure.

Or maybe it is the code from this hack:
+ /usr/bin/sed -r --in-place=.backup 's/^char \(\*f\) \(\) = /__attribute__
((used)) char (*f) () = /g' ./configure
+ /usr/bin/sed -r --in-place=.backup 's/^char \(\*f\) \(\);/__attribute__
((used)) char (*f) ();/g' ./configure
+ /usr/bin/sed -r --in-place=.backup 's/^char \$2 \(\);/__attribute__
((used)) char \$2 ();/g' ./configure
that is not accepted by the C++ compiler?
