(xarray-shared > being a subset of xarray.o which requires it anyway) After replacing main with vma and dropping the vma.c, I can generate the vma executable. I had to generate map-shift.h and bit-lenght.h, then execute: cc -O2 -g -Wall -I../shared -I. -I../../include -I../../../lib -g -Og -Wall -D_LGPL_SOURCE -fsanitize=address -fsanitize=undefined -c -o vma.o vma.c cc -c -O2 -g -Wall -I../shared -I. -I../../include -I../../../lib -g -Og -Wall -D_LGPL_SOURCE -fsanitize=address -fsanitize=undefined ../shared/linux.c -o linux.o cc -O2 -g -Wall -I../shared -I. -I../../include -I../../../lib -g -Og -Wall -D_LGPL_SOURCE -fsanitize=address -fsanitize=undefined -c -o slab.o ../../lib/slab.c cc -c -O2 -g -Wall -I../shared -I. -I../../include -I../../../lib -g -Og -Wall -D_LGPL_SOURCE -fsanitize=address -fsanitize=undefined ../shared/maple-shim.c -o maple-shim.o cc -O2 -g -Wall -I../shared -I. -I../../include -I../../../lib -g -Og -Wall -D_LGPL_SOURCE -fsanitize=address -fsanitize=undefined -c -o vma_stub.o vma_stub.c cc -fsanitize=address -fsanitize=undefined vma.o linux.o slab.o maple-shim.o vma_stub.o -lpthread -lurcu -o vma Dropping a number of the pre-built items. When I looked at the list, it seemed too numerous for what we were doing (why do we need idr, and radix-tree?) So I tried removing as many as I could. > > I'm not sure this is a huge big deal as these are all rather small :) Yeah, maybe not worth the effort. Cheers, Liam
