Hi, I am trying to build Fiasco-UX as per the documentation: http://os.inf.tu-dresden.de/fiasco/ux/building.shtml on Ubuntu Dapper (Intel, x86). gcc is 4.0.3. g++ is 4.0.3. I have obtained the code from CVS. Did menuconfig: cd l4/kernel/fiasco make menuconfig Have enabled: * Target platform (choose UX) * Generate inline code I don't see the "Assembler IPC shortcut" option. Saved the config. On running: make I get the following errors: make[1]: Circular l4/kernel/fiasco/src/Modules.ux.o <- Modules.ux dependency dropped. make[1]: Circular .Modules.deps <- Modules.ux dependency dropped. make[1]: Circular l4/kernel/fiasco/src/rules.cml.o <- Modules.ux dependency dropped. make[1]: Circular l4/kernel/fiasco/src/rules.cml.o <- .Modules.deps dependency dropped. make[1]: Circular create-sources <- Modules.ux dependency dropped. make[1]: Circular create-sources <- globalconfig.out dependency dropped. make[1]: Circular create-sources <- .Modules.deps dependency dropped. l4/kernel/fiasco/src/Makefile.sub1:17: .Modules.deps: No such file or directory make[2]: *** No rule to make target `.Modules.deps'. Stop. make[1]: *** [create-sources] Error 2 make: *** [build] Error 2 Appreciate any help in building fiasco-ux.
