Hi, I'm trying to cross-compile R to javascript so that it can run in a web-browser. Take as long as you need to stop laughing. So, as I was saying - I want to try and get a build of R running in the browser. [If you're not familiar with it already, you might enjoy looking at emscripten.org. It's a remarkably capable tool for translating LLVM bitcode to javascript. Check out some of

...ng error: Error in writeBin(raw(12501), con) : too large a block specified In investigating R's source, the difference seems to be in src/main/connections.c, in the function fifo_write() (around line 932). In R 3.0.3, fifo_write() has these lines: if ((double) size * (double) nitems > SSIZE_MAX) error(_("too large a block specified")); R 3.1.0 has these lines changed to this: if ((size * sizeof(wchar_t) * nitems) > 50000) { error(_("too large a block specified")); } The change effectively places a limit of 12500 bytes on writes (since sizeof(wchar_...

...; I'm still not clear if this is a GCC problem or a code problem, > although Dan pointed out on the list that SIZE_MAX is the largest > size_t, so I guess our code seems OK ... The error message seems to indicate that the compiler believes a pointer cannot reference an object larger than SSIZE_MAX and thus doesn't like the use of SIZE_MAX. This is quite strange though, given that malloc() and other C functions pretty much all use size_t for object sizes, not ssize_t. I think we should try reporting to the GCC maintainers for an opinion on whether its a compiler bug or not Regards, Da...

...le.in's accordingly - also adding instruction to link in a version of libf2c that I'd pre-compiled to LLVM bitcode. - I had to manually hack on the configure.h file to remove references to some functions that don't seem to exist in emscripten: ccosh, cexp etc. - I also added code to set SSIZE_MAX and R_XLEN_T_MAX to sensible values (thanks Peter). - I hacked connections.c as there were some duplicate case statements. I think this was because the ./configure was getting confused over the size of some basic types. I suspect all of above hacks could be avoided if I understood autotools better....

I'm not sure if this is a GCC bug or a bug in our code, but the attached workaround fixes it for me. Rich.

Add some warnings. Well, the first patch is a miscellaneous change, but patches 2-5 add some warnings. Rich.
