ld: warning: librpc.so, needed by out/target/product/passion/obj/lib/libgps.so, not found

[sbq]

Hi,

I am trying to build a system image for the Nexus One. I did a make
and it was chugging along for abot 20 minutes and then hit an error,
claiming it could not find librpc.so. Does anyone have any ideas
where this file should have come from?

To get to this point, I connected the Nexus One to my Ubuntu 8.10
Linux machine and ran the extract-files.sh script. Then this:

$ . build/envsetup.sh
$ lunch full_passion-userdebug
$ make
...
target thumb C++: app_process <= frameworks/base/cmds/app_process/
app_main.cpp
In file included from frameworks/base/include/android_runtime/
AndroidRuntime.h:29,

The way the GPS code gets built is different (and incompatible)
depending on whether you are using the proprietary binaries or not.

A full clean build (rm -rf out) should fix it, but I think you can get
away with:
find hardware/libhardware_legacy -type f | xargs touch

Hi JBQ,

I have tried both methods, i.e. "find" and "rm -rf out" but I ended up
with the same error. The platform code I pulled from Git is "froyo"
but the htc files I extracted came from the original 2.1-update1
version. Any other suggestions?

Thanks,
doug

What happens when you type:

$ mm librpc.so

at the same place you would normally type "make -j4"? That built libprc.so
for me.

Hi JBQ,

You can try (make librpm) I think that would compile librpm for you
and then you can continue the make process. I think the problem is
that librpc is not required to be build and the bild process is
looking for librpc.so any suggestions on how that could be fixed?

I am also having this issue. I have tried the methods JBQ suggested
and the result did not change. I am using the files extracted from
the N1 with Froyo 2.2 OTA update. I'd greatly appreciate any help
with this.

Thanks!

The source code of librpc is under: hardware/msm7k/librpc

If it didn't get built, it could be because the directory is not
included by the parent Makefile: hardware/msm7k/Android.mk. It has the
following lines to select what is included in the build:

common_msm_dirs := libcopybit liblights librpc
msm7k_dirs := $(common_msm_dirs) boot libgralloc libaudio
qsd8k_dirs := $(common_msm_dirs) libgralloc-qsd8k libaudio-qsd8k
dspcrashd

ifeq ($(TARGET_BOARD_PLATFORM),msm7k)
include $(call all-named-subdir-makefiles,$(msm7k_dirs))
else
ifeq ($(TARGET_BOARD_PLATFORM),qsd8k)
include $(call all-named-subdir-makefiles,$(qsd8k_dirs))
endif
endif

If TARGET_BOARD_PLATFORM is neither msm7k or qsd7k, librpc is not
built. I am not sure how to properly set TARGET_BOARD_PLATFORM for
your build. Just hope this info helps a bit.

Sam's method ($mm librpc.so) worked for me. Thanks, Sam.
