MinGW64 build

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

FYI - when I run the code ==================== #include <cln/cln.h> using namespace std; using namespace cln; const cl_univpoly_complex_ring CZ = find_univpoly_ring(cl_C_ring); struct parameter { cl_UP_N& p; }; parameter InitializeParameter(int n) { const cl_UP_N Z1 = CZ->monomial(1, 1); const cl_UP_N Z0 = CZ->monomial(1, 0); cl_R beta=random_F(cl_float(2)); cl_UP_N p=Z1-beta*Z0; parameter param={p}; return param; } int main(void) { default_float_format=float_format(200); parameter initparam=InitializeParameter(3); cout << initparam.p << "\n"; } =================== I get the error message and output ------------------- terminate called after throwing an instance of 'cln::notreached_exception' what(): Internal error: statement in file float/output/cl_F_dprint.cc, line 464 has been reached!! Please send the authors of the program a description how you produced this error! 1*x + -1.36062836991623237822723027868985516363623132879821473160126387357647155893917339260414115079493220011187343026833144928737100377766266870510325749056188223177423109599205862683403974607609610401462854382538584223Aborted --------------------- I haven't been able to reduce the code any further and still get the error - sorry!

fixing undefined references
by Michael Miller 27 Mar '14

I've spent 5 hours trying to understand the reason for an undefined reference, so I'm asking for some help. The code -------------------- #include <cstdlib> #include <gmp.h> #include <cln/cln.h> using namespace std; using namespace cln; const cl_univpoly_complex_ring CZ = find_univpoly_ring(cl_C_ring); struct parameter { cl_N z0; cl_UP_N p(); }; int main(void) { cl_UP_N q=CZ->create(1); q.set_coeff(1, 1); q.set_coeff(0, -1); q.finalize(); parameter param; param.z0=1; param.p()=q; } -------------------- produces the error message -------------------- /tmp/ccZPl6fM.o: In function `main': test.cpp:(.text+0xc6): undefined reference to `parameter::p()' collect2: error: ld returned 1 exit status -------------------- What am I doing wrong? Note: replacing p() with p, which would make more sense to me, generates compiler errors. Thanks, Mike

Windows 64-Bit

Dear Mr Kreckel, I tried to compile the CLN for Windows 64-Bit using x64, but during make I get an error: Type char* does not fit into a long!! What could I do to prevent this from happening? For 32-Bit it worked. Thank you very much and best regards, Christoph Jung Dr. Carl Christoph Jung Robert-Bosch-Zentrum für Leistungselektronik Hochschule Reutlingen Oferdinger Str. 50 72768 Reutlingen-Rommelsbach Tel.: 07121-271-7069
