dlopen failed: cannot locate symbol "dump_line"

Tried to compile apk from source code, and I get this error in run-time:

Maybe you have seen it before?

I forgot to add dump to the Makefile. Will commit a fix shortly.

[pftbest]

After adding dump.c, I get a compile error

dump.c:6:18: fatal error: date.h: No such file or directory
 #include "date.h"
                  ^
compilation terminated.

I can't find this date.h file anywhere. Was it present in some old version of ndk?

[gurrhack]

Now it's fixed for real. Sorry about that. (date.h is autogenerated during the build)

@gurrhack Yes, now it works, thanks!

Also my theory was correct, just changing one line from:

    <uses-sdk
        android:minSdkVersion="7"/>

to

    <uses-sdk
        android:minSdkVersion="7"
        android:targetSdkVersion="15"/>

Made the the game run much faster on high resolution screens. Especially noticeable when scrolling a long list of items for example.

This line allows the android to turn on hardware acceleration and leverage the GPU that is present in all devices since android 4.0. Also it will probably make the game more power efficient too. Give it a try.

[gurrhack]

I will, thanks.
