Default Bug#600921: libppl7: libppl should be configured with --enable-interfaces=c

Package: libppl7
Version: 0.10.2-8
Severity: important


Hello All,

I am the main other of GCC MELT, see http://gcc-melt.org/ or
http://gcc.gnu.org/wiki/MELT

Briefly: GCC MELT is a Lispy domain specific language to code GCC
extensions in. MELT is a GCC branch and a GCC plugin.

By the way, I am working on making very soon the first upstream
release of MELT, which should build as a plugin to unmodified GCC 4.5,
and Sylvestre Ledru offered me to try packaging it in experimental.

But GCC MELT depends upon some C functions existing in PPL 0.10.2
which are only available when it is configured with
--enable-interfaces=c at least. These functions are gcc-4.5 -g -DIN_GCC -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -Wold-style-definition -Wc++-compat -fno-common -DHAVE_CONFIG_H -o cc1 c-lang.o c-family/stub-objc.o attribs.o c-errors.o c-decl.o c-typeck.o c-convert.o c-aux-info.o c-objc-common.o c-parser.o tree-mudflap.o c-family/c-common.o c-family/c-cppbuiltin.o c-family/c-dump.o c-family/c-format.o c-family/c-gimplify.o c-family/c-lex.o c-family/c-omp.o c-family/c-opts.o c-family/c-pch.o c-family/c-ppoutput.o c-family/c-pragma.o c-family/c-pretty-print.o c-family/c-semantics.o c-family/c-ada-spec.o i386-c.o

If you want to reproduce the bug, try compiling the GCC MELT branch
the following way:

0. Retrieve the source code using
svn co -r 165768 svn://gcc.gnu.org/svn/gcc/branches/melt-branch
gcc-MELT

1. make a fresh build directory, eg
mkdir ../MELT-BUILD

2. Go into it and configure it with e.g.
cd ../MELT-BUID
../gcc-MELT/configure '--libdir=/usr/local/lib/gcc-melt'
'--libexecdir=/usr/local/libexec/gcc-melt'
'--with-gxx-include-dir=/usr/local/lib/gcc-melt/include/c++/'
'-with-ppl' '--with-mpc' '--enable-maintainer-mode'
'--enable-checks=tree,gc' '--disable-bootstrap'
'--disable-multilib' '--with-ppl-lib=-lppl_c -lppl'
'--enable-version-specific-runtime-libs' '--enable-plugins'
'--enable-languages=c,c++,lto'

3. Try to build it with
make

BTW, the same bug appears both on testing and on sid.

Proposed fix: in the Debian package of libppl 0.10.2 (or 0.11)
configure it with --enable-interfaces=c at least.

Comment: Roberto Bagnara, the main author of PPL, did add (a few years
ago) the functions `ppl_io_asprint_Coefficient'
`ppl_io_asprint_Linear_Expression' `ppl_io_asprint_Constraint'
`ppl_io_asprint_Constraint_System' for the GCC MELT branch.

Regards, and thanks for the good work!
