Thank you ,Alexei but that didn't work. i had tried, :( i suppose the point is how comes this message when compiling and linking cln : >C:/ooo/1.0/GiNaC1/lib/libcln.a(cl_LF_1plus.o): In function `subx_loop_up': >C:\msys\1.0\home\Lenovo\cln-1.3.1\src/./base/digitseq/cl_DS.h:406: undefined >reference to `_imp____gmpn_sub_n' it seems that the CLN and GINAC was compiled with position dependent things written into cln lib files , By the Way, when i type "pkg-config.exe --libs cln" in MSYS shell, it gives "-LC:/ooo/1.0/GiNaC1/lib -lcln" . it should have been "-L/GiNaC1/lib -lcln" , am i right? wayne

CLN compile errors on GCC4.2
by Vipin Varma 26 May '10

26 May '10

Hi, I've been using CLN 1.3.1 successfully with the GCC4.3 compiler. Now I am running my code using the GCC4.2 on another machine (in which I dont have the option of updating to the newer GCC): <SNIP> In file included from /users/varma/cln-1.3.1/include/cln/string.h:7, from /usr/include/c++/4.2/cstring:52, from /usr/include/c++/4.2/i486-linux-gnu/bits/c++locale.h:47, from /usr/include/c++/4.2/iosfwd:45, from /usr/include/c++/4.2/ios:43, from /usr/include/c++/4.2/ostream:45, from /usr/include/c++/4.2/iostream:45, from graph.cpp:12: /usr/include/cln/io.h:22: error: expected initializer before & token /usr/include/cln/io.h:23: error: expected initializer before & token /usr/include/cln/io.h:24: error: expected initializer before * token ........ ........ ........ //and many more errors// <SNIP> Lines 22-24 of cln/io.h contain the following: <SNIP> typedef std::istream& cl_istream; typedef std::ostream& cl_ostream; extern std::ostream* cl_debugout_stream; #define cl_debugout (*cl_debugout_stream) <SNIP> My guess is that the streams are not recognised due to circular referencing (but which are the two, or more, files that are responsibile for this, I am not sure), which is somehow taken care of in the newer GCC. Any advice on this will be appreciated. Vipin

Re: [CLN-list] CLN-list Digest, Vol 49, Issue 3
by Joshua Friedman 26 May '10

26 May '10

Alexei Thanks for answering my question. I think I understand what to do. Suppose I say, cln_R x = 3.4; then I computer exp(x), now I convert it to cln_F, Can I do so at any precision. Is exp(x) just a symbolic computation, and does the actual computation come about only when converting to a cln_F?

confusion with cln::cl_F and cln::cl_R
