Thank you so much. We shall try it! ________________________________________ From: Users-prolog [users-prolog-bounces+anoriega=njcu....@gnu.org] on behalf of Dan Hitt [dan.h...@gmail.com] Sent: Monday, March 19, 2018 11:56 PM To: users-prolog@gnu.org Subject: installed gprolog 1.4.4 on debian 9 (stretch) with gcc 6.3 in a kind of hackey way, please lmk of a better way if possible
I have a debian 9 system on which i tried to build gprolog 1.4.4. It was unsuccessful, as a very vanilla build ran into problems where some of the *.o files had relocation type R_X86_64_32S and thus could not be linked into shared objects. The net had some information about this, including some helpful advice from Salvador A, in response to a question Sean. The gist of their discussion was to get in flags -fPIC and -no-pie to gcc. I did this, but it was not quite enough. So i'm describing here how i hacked it through, but would greatly appreciate any information on how to do a build without hand-modifying any Makefiles. My configure command was ./configure --prefix=$HOME/path/to/dir --with-c-flags="-fPIC -no-pie" After configuring, make would fail with the bad relocation type, but only the files compiled from wam sources triggered the error. So in the bowels of the build system, it looks like although gcc was getting the -fPIC -no-pie flags, gplc was not. So i edited 4 Makefiles, in the directories BipsPl, Pl2Wam, Fd2C, BipsFD. In each of those directories, if the variable GPLCFLAGS was specified (generally to --fast-math), i changed it by adding -fPIC (so that it would be --fast-math -fPIC). Also, in the directories BipsPl and Pl2Wam i added -fPIC to the rule for .wam.o files. In the directory BipsFD, GPLCFLAGS was used, but not defined, so i made it equal to -fPIC. I did not put --fast-math on it, because i don't really know what i'm doing here. With these changes, made to a configured but otherwise completely clean extraction, compilation was successful and at least the program gprolog is willing to accecpt input. (I haven't pushed it very hard, so we'll see how things go.) Note that i did not pass -no-pie to gplc, because it does not accept that option. I imagine this process is far short of ideal, so i'd be grateful for any clues on how to do this without hand-editing any Makefiles. For example, a configure option of --with-gplc-flags would be useful, but ./configure --help does not reveal such a flag. In any event, i'm posting because i don't think my system is very unique and other debian users may run into this problem. Thanks for any guidance! :) dan _______________________________________________ Users-prolog mailing list Users-prolog@gnu.org https://lists.gnu.org/mailman/listinfo/users-prolog _______________________________________________ Users-prolog mailing list Users-prolog@gnu.org https://lists.gnu.org/mailman/listinfo/users-prolog
