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: [Select]

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

Seems OK, but as soon as I do "make fullinstall" I get:

Code: [Select]

Installing a full setup in your '' dir
ERROR: No PREFIX given
make: *** [fullinstall] Error 255

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:

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: [Select]

/* on some platforms strcmp() seems to be a tricky define which
 * breaks if we write down strcmp's prototype */

Here are the diffs:

With the new #undefs, bookmark.c compiles fine.

2) In makefile, "-z,defs" not recognized:

Code: [Select]

export GLOBAL_LDOPTS= -Wl,-z,defs

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: [Select]

LD vorbis.codec
ld: -allow_stack_execute option can only be used when linking a main executable

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.

Up 

Anybody knowing this -fnested-funtions and -allow_stack_execution stuff ?

Firmware builds fine, but I can't build the UIsim

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.

In the mean time you could use a VM like Windows users do.

Unless I'm wrong, there's no such a thing as Vmware player (free) for Mac OS.
The Mac thingy (fusion) is not free (30 days trial).

Thanks anyway. Don't worry too much, as in a few weeks I'll be back at home where I have a PC, so I'll go down the VMware path for sure.
I was just curious as the firmware builds fine and the error with the UIsim seemed minor at first glance (just use -fnested-functions) but turned out to be way too much for my limited knowledge of all this stuff.
A few references I've googled around, if it can help:

In case I really have some extra-spare time, I may take a look at virtualbox (http://www.virtualbox.org/).

Use the virtualbox image linked on the wiki.

Gosh, I skipped that line in the wiki.
Tried vitualbox with the provided image, everything compiles fine.
Now I have just to sort out a 'sgared dir" error and then I'm fine

Hi all,
I also have a problem with uisimulator, nearly same as HornetMaX so I keep it in this topic.
My configs are MINGW with Win7 and I  can compile (after much hassle) a Sansa Clip simulator with
../tools/configure
make
make fullinstall

The file generated is sim/rockockui.exe and I have all the pseudo-firmware files in sim/simdisk/.rockbox
I can launch it with Windows, can see the Sansa Clip screen and can browse the list of test mp3 files I dropped in sim/simdisk

Now the problem : when I try to play a mp3 files or launch a plugin (eg Reversi), I get the error messages

failed to load /.rockbox/codecs/mpa.codec
lc_open(/.rockbox/codecs/mpa.codec): Le module spÚcifiÚ est introuvable.
failed to load /.rockbox/rocks/games/reversi.rock
lc_open(/.rockbox/rocks/games/reversi.rock): Le module spÚcifiÚ est introuvable

I don't undertand the problem since all the codecs or pluggins are generated in the right path sim/simdisk/.rockbox. It's as if the simulator doesn't get its root path right!
Anyone can help, me please ?

[bluebrother]

It would be helpful to have the error messages in english.

[hobby16]

I don't know how to generate a target in English but the message is something like

failed to load /.rockbox/codecs/mpa.codec
lc_open(/.rockbox/codecs/mpa.codec): can't find module mpa.codec
