I refuse to do anything more in dos batch files :)Hello Jason,Sometimes ago, I managed to cross-compile and test PARI on MinGW on the pari host,and I have report that it is possible to build PARI on MinGW using MSYS.So I wonder: instead of fighting with cmd.com, why not use MSYS to build pari withMSVC ? This should make the task significantly easier. Cheers, Bill.
Yeah I have thought of that , now I got my windows box up and running again(well nearly , I cant install SP2 for some reason) , I'm going to give it a go
see this discussion http://groups.google.com/group/mpir-devel/browse_thread/thread/a3ea8063a0a1a823 message 8 4) Get autotools to run NATIVE in windows with MSVC . What I have in mind is really a trick , there are two parts to it , 1) get it use cl.exe instead of gcc.exe 2) hide the fact that we are running under another shell. autotools can run cl.exe , no problem , just like it can run cc or icc , theoptions are a little different , but a script can easily take care of that (as long as everything is one-to-one) , once we have this bit , then we could get
a MSVC compile under cygwin or minGW . The next stage is to have a "hidden install" of minGW so we can run autotools, (just like we do for yasm under linux). Thanks Jason
