I'm creating a new project that uses existing libraries, e.g. seL4_libs/libsel4utils, a header page_dma.h, because I want to use dma in my IO transfer. When I include header page_dma.h in question, at line 15, <autoconf.h> is pulled in. There are 100s of autoconf.h files (usually auto-generated ones in kernel binaries) and I have no idea which one should be included and how to setup -I option for gcc to include it. Can anyone educate me on it? Thanks very much!
