Hello,
My question is: Can I use the 64-bit gcc to build a 32-bit package with the -m32 command line option with Rtools? And, can that work for CRAN? Or more generally, is there a work-around for needing lots of RAM during compilation with the 32-bit compiler? The background is: I'm trying to compile a the development version of RxODE (https://github.com/nlmixrdevelopment/RxODE/issues/278), but I'm hitting 32-bit memory limits (using >3GB and possibly >4GB RAM during compilation) using the 32-bit version of gcc. Specifically, "C:/rtools40/mingw32/bin/"gcc [etc., see the link above for the full command line] yields the error cc1.exe: out of memory allocating 65536 bytes There is no problem building with mingw64, and I played around to confirm that by using: Sys.setenv(BINPREF="c:/rtools40/mingw64/bin/") And compilation completed successfully (though installation failed as expected because the compiled .dll couldn't load on 32-bit R).
