Historically $(OBJECTDIR) was created when Makefile.include is read. A
consequence is that combining "clean" with "all" (or any other build
target) results in an error because the clean removes the object
directory that is required to exist when building dependencies.
Creating $(OBJECTDIR) on-demand ensures it is present when needed.
Removed creation of $(OBJECTDIR) on initial read, and added an order-only
dependency forcing its creation all Makefile* rules where the target is
explicitly or implicitly in $(OBJECTDIR).
At least with gcc (and cc65) the dependency files are generated without an additional run of the C compiler. This is especially beneficial on Cygwin because of the fork() performance issue.
In order to support, some core modules are modified as follows:
core/sys/dsc.h
- If CTK_CONF_ICONS is diabled, the whole icon-related code is disabled.
- DSC_HEADER is changed to remove extra semicolon.
core/sys/process.h
- process_data_t is expressed by void* in signatures (known bug on sdcc).
core/sys/autostart.h
- autostart_processes is changed to remove extra semicolon.
core/sys/cc.h
- CC_CONF_ASSIGN_AGGREGATE is introduced.
- CC_CONF_INC_CAST_POINTER is introduced, a workaround of a kind
of sdcc bug for an increment.
core/net/hc.c
core/net/uip_arp.c
core/net/uaodv.c
- Aggregation assignments are changed to uip_ipaddr_copy.
core/net/psock.c
core/net/uipbuf.c
core/net/dhcpc.c
apps/shell/shell.c
core/ctk/vnc-server.c
core/ctk/vnc-out.c
- "register" keyword in a signature cannot be used in sdcc,
CC_REGISTER_ARG is used instead.
core/net/uip-over-mesh.c
- An extra semicolon is removed.

to prevent a compile error.
core/net/mac/xmac.c
- Variables cannot be defined in a head of block on sdcc.
core/ctk/ctk.h
core/ctk/ctk.c
apps/program-handler/program-handler.c
- If CTK_CONF_ICONS is diabled, the whole icon-related code is disabled.
Makefile.include
- Add a set of configuration for an assembler.
- $(CLEAN) variable is introduced for customized cleanup.
apps/process-list/process-list.c
- PROCESSLIST_CONF_HEIGHT is introduced to address smaller screen size.
core/lib/ctk-filedialog.c
- FILES_CONF_HEIGHT is introduced to address smaller screen size.
- "register" keyword in a signature cannot be used in sdcc,
CC_REGISTER_ARG is used instead.
apps/vnc/vnc-viewer.c
- A cast is added to prevent a compile error.
- "register" keyword in a signature cannot be used in sdcc,
CC_REGISTER_ARG is used instead.
apps/webbrowser/webclient.c
- CC_CONF_INC_CAST_POINTER is introduced, a workaround of a kind
of sdcc bug for an increment.
core/loader/elfloader.c
- A cast is added to prevent a compile error.
core/net/rime/rimeaddr.c
- An initialization is added to prevent a compile error.
core/net/rime/rudolph0.c
- NULL is changed to 0, because NULL causes a compile error.
