Hi Denys, This would be a very nice option, and while I'm currently able to tinker with the asm for a single applet it would be preferable to have the entire busybox program compiled to a single .s file. I've tried playing with Makefile.IMA, and more generally with the "--combine" option to GCC, however I keep running into the same error, namely include/libbb.h:1670: error: conflicting types for ‘ptr_to_globals’ It seems that this error has cropped up in the past. http://lists.busybox.net/pipermail/busybox/2007-March/060781.html http://www.mail-archive.com/busybox@busybox.net/msg04074.html Unfortunately these messages haven't indicated a viable solution. Thanks for the suggestion, when scripts/Makefile.IMA is once again in a working state, sneaking a -S into the gcc invocation should work well.
