Hi Pietro, Sorry for the late reply -- the last few days have been quite busy for me at work. Anyway, I haven’t been following recent developments in the Debian package repos lately so I wasn’t aware that our packages (that we mainly build for Ubuntu Linux and not Debian) do not work with the most recent Debian release -- they used to work for quite a long time.
Anyway, I’m installing Debian in a VM now and I’ll read your emails carefully. Hopefully I’ll be able to figure out what’s wrong soon and then I’ll send you an updated package (and probably send a patch to the Debian project as well). All the best, -- T. ------------------------------------------------------ From: Pietro Battiston [email protected] Reply: Pietro Battiston [email protected] Date: 20 March 2014 at 10:33:15 To: Tamás Nepusz [email protected] Cc: Help for igraph users [email protected] Subject: Re: [igraph] Import error in Python > Il giorno mer, 19/03/2014 alle 23.49 +0100, Tamás Nepusz ha scritto: > > Hello, > > > > Can you please try the packages from > > https://launchpad.net/~igraph/+archive/ppa instead of the official > > Debian repos? > > If I simply install the python-igraph package from there, (with or > without recompiling it), I get the same exact problem. > > If I try to install your version of libigraph0-dev in order to recompile > it, I'm asked to install the corresponding version of libigraph0, (which > makes sense). > > If I try to install the corresponding version of libigraph0, I am stuck > with a dependency, libglpk0, which is not present in the (debian > testing) archives. > > If I try to remove the dependency and rebuild libigraph0-dev, I get an > error "dpkg-source: error: can't build with source format '3.0 > (native)': native package version may not have a revision". > > If I change the content of debian/format/source to "3.0 (quilt)" and > again rebuild, I get an error "dpkg-source: error: can't build with > source format '3.0 (quilt)': no upstream tarball found > at ../igraph_0.6.5.orig.tar.{bz2,gz,lzma,xz}" > > If I give "ln -s igraph_0.6.5-4~ubuntu13.04.1.tar.gz > igraph_0.6.5.orig.tar.gz" in the parent directory and again rebuild, the > build process goes on a bit, then stops with > "libtool: compile: gcc -DHAVE_CONFIG_H -I. -I.. -g -O2 > -I/usr/include/libxml2 -I../include -I../include -Wall -g -O2 > -I/usr/include/libxml2 -c foreign-ncol-parser.c -o > libigraph_la-foreign-ncol-parser.o >/dev/null 2>&1 > /bin/bash ../ylwrap foreign-ncol-lexer.l lex.yy.c foreign-ncol-lexer.c > -- flex > /bin/bash ../libtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I. > -I.. -g -O2 -I/usr/include/libxml2 -I../include -I../include -Wall -g > -O2 -I/usr/include/libxml2 -c -o libigraph_la-foreign-ncol-lexer.lo > `test -f 'foreign-ncol-lexer.c' || echo './'`foreign-ncol-lexer.c > libtool: compile: gcc -DHAVE_CONFIG_H -I. -I.. -g -O2 > -I/usr/include/libxml2 -I../include -I../include -Wall -g -O2 > -I/usr/include/libxml2 -c foreign-ncol-lexer.c -fPIC -DPIC > -o .libs/libigraph_la-foreign-ncol-lexer.o > In file included from foreign-ncol-lexer.l:49:0: > foreign-ncol-parser.h:88:26: error: unknown type name > 'igraph_i_ncol_parsedata_t' > int igraph_ncol_yyparse (igraph_i_ncol_parsedata_t* context); > ^ > make[4]: *** [libigraph_la-foreign-ncol-lexer.lo] Error 1 > make[4]: Leaving directory > `/home/pietro/cancellami/versione_ubuntu/igraph-0.6.5/src' > make[3]: *** [all] Error 2 > make[3]: Leaving directory > `/home/pietro/cancellami/versione_ubuntu/igraph-0.6.5/src' > make[2]: *** [all-recursive] Error 1 > make[2]: Leaving directory > `/home/pietro/cancellami/versione_ubuntu/igraph-0.6.5' > make[1]: *** [all] Error 2 > make[1]: Leaving directory > `/home/pietro/cancellami/versione_ubuntu/igraph-0.6.5' > dh_auto_build: make -j1 returned exit code 2 > make: *** [build] Error 2 > dpkg-buildpackage: error: debian/rules build gave error exit status 2 > " > > At this point I gave up - I will simply wait and hope for the Debian bug > to be solved, and in the meanwhile find some other solution. > > By the way: I may be wrong, but to the best of my understanding, the > line "dh $@ --with python2" in the debian/rules of your igraph package > does not make much sense - this is not a python package.
