Hi,

I tried to compile KPDFViewer, but I was unsuccessful. I'm a total noob with this, so don't be surprised if you read something stupid. This is what I did:

I have a Windows 7 64-bit box, so I made a Virtual machine using VirtualBox and installed Ubuntu 12.04 Desktop 32-bit, with default settings. (It shouldn't matter that I'm using a virtual machine, but I'm stating it for completeness sake).

In my previous attempts I realised that default installation lacked some packets, so this time I added them first:

$ sudo apt-get install git

$ sudo apt-get install g++

$ sudo apt-get install lua5.1

$ sudo apt-get install cmake

$ sudo apt-get install libsdl1.2-all

$ sudo apt-get install libsdl1.2-dev

$ sudo apt-get install gcc-arm-linux-gnueabi

$ sudo apt-get install g++-arm-linux-gnueabi

(I know I could've added them all in one line, but since I added them one by one... )


Then, I cloned the repository (I hope this is the correct terminology... I never used git before):

$ git clone https://github.com/hwhw/kindlepdfviewer.git

and then

$ cd kindlepdfviewer

Then I edited Makefile, changing

HOST:=arm-none-linux-gnueabi

into

HOST:=arm-linux-gnueabi

after that, I did:

$ make fetchthirdparty

This far everything seemed to be ok. From this point on, I did 2 separate attempts: A - make for ARM and B - make for emulation.


A - Make for ARM
-----------------

$ make thirdparty

I had some warnings here, mostly "defined but not used", but it seemingly went ok, too. I have full log files, but since they're kinda long, I'm reluctant to attach them if it's not necessary. Here are a few of the last lines:

make[1]: Leaving directory `/home/kai771/kindlepdfviewer/kpvcrlib'

Then I did

$ make kpdfview

This didn't end that well. A few of the last lines:

crtxtenc.cpp:(.text._ZN16CDoubleCharStat25CloseEv[CDoubleCharStat2::Close()]+0x10): undefined reference to `operator delete[](void*)'

make: *** [kpdfview] Error 1

Now, I should've probably used Code Sourcery toolchain here instead of Linaro that goes with Ubuntu? Do I need to use scratchbox2? Copy libraries from Kindle? How? Anyone cares to explain?




B - Make for Emulation
-----------------------

Unrelated to the A above, I did this for emulation:

$ EMULATE_READER_W=600 EMULATE_READER_H=800 EMULATE_READER=1 make thirdparty

Similar to previous attempt, some warnings, but seemingly ok. Few of the last log lines:

[ 96%] Building CXX object crengine/crengine/CMakeFiles/crengine.dir/src/chmfmt.cpp.o
[ 97%] Building CXX object crengine/crengine/CMakeFiles/crengine.dir/src/epubfmt.cpp.o
[ 98%] Building CXX object crengine/crengine/CMakeFiles/crengine.dir/src/pdbfmt.cpp.o

[100%] Built target crengine
make[2]: Leaving directory `/home/kai771/kindlepdfviewer/kpvcrlib'
make[1]: Leaving directory `/home/kai771/kindlepdfviewer/kpvcrlib'

Then, I did:

$ EMULATE_READER_W=600 EMULATE_READER_H=800 EMULATE_READER=1 make kpdfview

and got this in the end

kpvcrlib/crengine/crengine/libcrengine.a(crtxtenc.cpp.o):(.rodata._ZTI16CDoubleCharStat2[typeinfo for CDoubleCharStat2]+0x0): undefined reference to `vtable for __cxxabiv1::__class_type_info'

collect2: ld returned 1 exit status
make: *** [kpdfview] Error 1

So, what am I doing wrong? Am I wrong to think that the choice and even presence of ARM compiler has nothing to do with building it for device emulation? Again, I have the full logs of the make output, and I can attach them if needed, but I get the feeling that I'm missing something simple, something that an experienced developer would spot from a mile away .

Thanks for your patience.
