    <p>I am trying to cross-compile a very simple program for Android that <em>worked</em> with android-ndk-r6b and prior, but does <em>not</em> work on android-ndk-r7 and newer:</p> <pre><code>int main() { ; return 0; } </code></pre> <p>I was able to do so using an "agcc" script on an older version of Android that can be found <a href="http://plausible.org/andy/agcc" rel="nofollow">here</a>. I'm sincerely not trying to use an Android.mk file to build this. I know I can, but this is part of something much larger I'm working on. So take it for face-value that I am trying to cross-compile this in a different way.</p> <p>Anyway, I try to build and get:</p> <pre><code>$ arm-eabi-gcc -o test test.c /home/gnychis/Documents/android/os/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/../lib/gcc/arm-eabi/4.4.3/../../../../arm-eabi/bin/ld: warning: /tmp/cc00QD3x.o uses variable-size enums yet the output is to use 32-bit enums; use of enum values across objects may fail /tmp/cc00QD3x.o:(.ARM.exidx.text.main+0x0): undefined reference to `__aeabi_unwind_cpp_pr0' collect2: ld returned 1 exit status </code></pre> <p>So, the key error is the undefined reference to __aeabi_unwind_cpp_pr0.</p> <p>After doing some digging, this symbol is in libgcc.a which I am linking to:</p> <pre><code>$ arm-eabi-nm /home/gnychis/Documents/android/os/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/lib/gcc/arm-eabi/4.4.3/libgcc.a | grep __aeabi_unwind_cpp_pr0 U __aeabi_unwind_cpp_pr0 U __aeabi_unwind_cpp_pr0 U __aeabi_unwind_cpp_pr0 U __aeabi_unwind_cpp_pr0 U __aeabi_unwind_cpp_pr0 U __aeabi_unwind_cpp_pr0 U __aeabi_unwind_cpp_pr0 00000590 T __aeabi_unwind_cpp_pr0 U __aeabi_unwind_cpp_pr0 U __aeabi_unwind_cpp_pr0 </code></pre> <p>It has a 'T' which tells me that it is in the code somewhere, right?</p> <p>Here is the verbose output of arm-eabi-gcc which shows I am in fact linking to this library:</p> <pre><code>Using built-in specs.

    1. COas it turns out, I do not get this error with NDK-6 and NDK-6b. However, I do get this error with NDK-7 and NDK-7b. Something must have changed. Am i missing some sort of compiler/link flag now?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
