I do not really know what happens. You seems to compile pari-2.2.11.bill which is a totaly experimental version. You should probably rather get a CVS snapshot from here: <http://pari/cgi-bin/viewcvs.cgi/pari/pari.tar.gz?tarball=1> It will probably not make a difference here, thought. > Major updates as following : > > gcc 3.3.1 => gcc 3.4.4 this one is known to cause problems. > fltk 1.1.4-1 => 1.1.4-2 > readline 4.03 => 5.02 Theses 2 should be OK. > 1) problem related to gcc ? : > > g++ -c -O3 -DGCC_INLINE -Wall -fno-strict-aliasing -fomit-frame-pointer -I. -I../src/headers -I//include -o plotfltk. > o ../src/graph/plotfltk.c > cc1plus: //include: No such host or network path Apparently g++ now treat //include as a network path using the double root convention (like SMB //host/share syntax). It is traditional on UNIX to handle //include as an alias for /include. You can try to use "/". as the fltk directory instead of "/" (by doing '--with-fltk=/.'). Maybe we can fix that in Configure, but this is a pretty weird behaviour of g++ or cygwin. > 2) problem related to readline : > > Creating library file: libpari.dll.a > default.o:default.c:(.text+0x1578): undefined reference to `_init_readline' > collect2: ld returned 1 exit status > make: *** [libpari-2.2.dll] Error 1 > make: Leaving directory `/home/Administrateur/pari-2.2.11.bill/Ocygwin-i686' > make: *** [bench] Error 2 This is bug #261, not yet solved. It is not critical on Linux since here it is possible to build libraries with undefined symbols. Cheers, Bill.
