MinGW64 build
by Robert Szalai 05 Nov '19

05 Nov '19

Hi all, I've been trying to build CLN from windows 64, with some success. It compiles fine, but does not work. The problem is that WIN64 is LLP64, and not ILP64 as Linux. CLN uses long to store pointer data, but size_t or ssize_t should be used as it is guaranteed to be the size of the pointer everywhere. The attached patch was my attempt. Could somebody tell me where else should I look? Pointers are also encoding some metadata in the bits that are set to zero by alingnment, what is this data? There is also some hashing of pointers. Thanks, Robert

cygwin help

Greetings, I have been forced to install ginac on a windows machine and I ran into unexpected problems. Everything I found on the web is quite old, e.g.: http://www.ginac.de/pipermail/cln-list/2006-August/000212.html and this ( http://www.richelbilderbeek.nl/CppClnInstallCygwin.htm ) claims that ./configure make make check make install should do the trick, even in cygwin. So, where might I get help when I see something like this(?): ~~~ $ make Making all in src make[1]: Entering directory '/home/andrei/cln-1.3.3/src' /bin/sh ../libtool --tag=CXX --mode=compile g++ -DHAVE_CONFIG_H -I. -I../autoconf -I../include -I../src -I../include -I../src -g -O2 -MT cl_2DS_div.lo -MD -MP -MF .deps/cl_2DS_div.Tpo -c -o cl_2DS_div.lo `test -f 'base/digitseq/cl_2DS_div.cc' || echo './'`base/digitseq/cl_2DS_div.cc libtool: compile: g++ -DHAVE_CONFIG_H -I. -I../autoconf -I../include -I../src -I../include -I../src -g -O2 -MT cl_2DS_div.lo -MD -MP -MF .deps/cl_2DS_div.Tpo -c base/digitseq/cl_2DS_div.cc -o cl_2DS_div.o In file included from base/digitseq/cl_2DS_div.cc:13:0: ./base/digitseq/cl_DS.h: In function 'uintD cln::add_loop_up(const uintD*, const uintD*, uintD*, uintC)': ./base/digitseq/cl_DS.h:378:54: error: invalid conversion from 'uintD* {aka long unsigned int*}' to 'mp_ptr {aka long long unsigned int*}' [-fpermissive] return mpn_add_n(destptr,sourceptr1,sourceptr2,count); [...lots more...] In file included from ./base/digitseq/cl_DS.h:360:0, from base/digitseq/cl_2DS_div.cc:13: /usr/include/gmp.h:1496:26: error: initializing argument 3 of 'mp_limb_t __gmpn_divrem_1(mp_ptr, mp_size_t, mp_srcptr, mp_size_t, mp_limb_t)' [-fpermissive] __GMP_DECLSPEC mp_limb_t mpn_divrem_1 (mp_ptr, mp_size_t, mp_srcptr, mp_size_t, mp_limb_t); ^ Makefile:2672: recipe for target 'cl_2DS_div.lo' failed make[1]: *** [cl_2DS_div.lo] Error 1 make[1]: Leaving directory '/home/andrei/cln-1.3.3/src' Makefile:665: recipe for target 'all-recursive' failed make: *** [all-recursive] Error 1 ~~~ Best, Andrei
