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

I fixed my problem: ./configure CXX=/usr/bin/clang++ CXXFLAGS="-stdlib=libc++ -std=c++11" LDFLAGS="-stdlib=libc++" and then add an include for string (#include <string>) to exception.h (should be considered a bug? Thanks to Howard Hinnant from Stackoverflow for helping) Now CLN compiles as expected. 2013/10/18 <cln-list-request(a)ginac.de> > Send CLN-list mailing list submissions to > cln-list(a)ginac.de > > To subscribe or unsubscribe via the World Wide Web, visit > https://www.cebix.net/mailman/listinfo/cln-list > or, via email, send a message with subject or body 'help' to > cln-list-request(a)ginac.de > > You can reach the person managing the list at > cln-list-owner(a)ginac.de > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of CLN-list digest..." > > > Today's Topics: > > 1.

Compile cln linked against libc++
by Stefan Schupp 17 Oct '13

Hi, I am currently trying to compile cln with linkage against libc++. My aproach was: /configure CXX=/usr/bin/clang++ CXXFLAGS=-stdlib=libc++ However this does not work as I get erroneus output such as In file included from base/cl_alloca.cc:4: In file included from ./base/cl_sysdep.h:56: In file included from ./base/cl_macros.h:7: ../include/cln/exception.h:14:24: error: implicit instantiation of undefined template 'std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >' : std::runtime_error(std::string()) {} ^ /usr/bin/../lib/c++/v1/iosfwd:187:28: note: template is declared here class _LIBCPP_TYPE_VIS basic_string; What does this mean and what am I doing wrong? I need this in order to compile ginac with the same linkage as it is used in a project with c++11 features. Best regards, Stefan
