UIsimulator error on make install
HornetMaX:
Hi all,
I'm trying to compile RB and its UIsim on a Mac (OS X 10.6.7). I think I've followed the instructions pretty well, since:
- I can build the firmware (for a clip+), with "make" + "make fullzip". I haven't tested the firmware I've built but I have no reason to doubt about it.
- I can build the UIsimulator with a "make" (in a separate dir with respect to the one I have used for the firmware).
The make process ends with:
--- Code: ---CC apps/plugins/lua/rocklua.c
CC apps/plugins/lua/luadir.c
GEN actions.lua
GEN buttons.lua
GEN rocklib_aux.c
CC rocklib_aux.c
LD lua.rock
Creating rockbox-info.txt
--- End code ---
Seems OK, but as soon as I do "make fullinstall" I get:
--- Code: ---Installing a full setup in your '' dir
ERROR: No PREFIX given
make: *** [fullinstall] Error 255
--- End code ---
Same for a "make install". I don't see the expected "rockboxui" executable neither (not sure if it is created by the "make install/fullinstall").
Any idea what's wrong ?
MaX.
EDIT:
Even stranger ... I tried a make clean (in UIsim dir) and a new "../tools/configure" followed by a new "make" and now I get a compile error:

:o ???

OK, I managed to figure out a few problems compiling the UIsim on Mc OS X.
1) In apps/plugin.h and apps/codecs/lib/codeclib.h, some prototypes need an "#undef" before
the prototype declaration. I've found this by chance, thanks to the following comment in codeclib.h:
--- Code: ---/* on some platforms strcmp() seems to be a tricky define which
* breaks if we write down strcmp's prototype */
--- End code ---

--- End code ---
With the new #undefs, bookmark.c compiles fine.
2) In makefile, "-z,defs" not recognized:
--- Code: ---export GLOBAL_LDOPTS= -Wl,-z,defs
--- End code ---
I had to remove the "-z,defs". Then linker seems to work fine.
3) Compile error (in apps/codecs/mp3_enc.c): "nested functions are disabled, use -fnested-functions to re-enable"
Added "-fnested-functions" to GCCOPTS in Makefile.
But now I'm stuck with a new error:
--- Code: ---LD vorbis.codec
ld: -allow_stack_execute option can only be used when linking a main executable
--- End code ---
Notice that this link step was reporting no error prior to the addition of the -fnested-functions.
I have grepped for "allow_stack_execute" in all source code but I haven't found it, hence I guess that the option is somehow automagically added as a consequence of the -fnested-functions.
Anyone has an idea ?
MaX.
HornetMaX:
Up ;D
Anybody knowing this -fnested-funtions and -allow_stack_execution stuff ?
Firmware builds fine, but I can't build the UIsim ???
MaX.
bluebrother:
I wanted to look into this since it came up but haven't found the time to do so (and I'm unlikely to find the time the next couple of days). Most Rockbox developers are working on Linux so I'm not surprised at all the sim doesn't build on OS X.
saratoga:
In the mean time you could use a VM like Windows users do.
