Hey, Am trying to tidy up my patch for #10732, but running into issues getting Jam to pickup a dependency correctly. In src/bin/writembr/Jamfile, I have: Object [ FGristFiles mbr.bin ] : mbr.nasm ; DataFileToSourceFile [ FGristFiles MBR.h ] : [ FGristFiles mbr.bin ] : kMBR : kMBRSize ; And in src/add-ons/kernel/partitioning_systems/intel/Jamfile, I can't seem to get it to depend on MBR.h correctly, so the DataFileToSourceFile rule never gets invoked. If I jam writembr; jam intel, then MBR.h gets generated from writembr, and then the intel add-on successfully finds MBR.h. In the Jamfile I have: UseHeaders ] FDirName $(HAIKU_COMMON_PLATFORM_OBJECT_DIR) bin writembr ] ; And this sets up the include path correctly; but I have no idea for making the generated MBR.h happen. - Jessica
