Re: gc 7.4.0 on Android

Hi Manuel,

> 1. please check you NDK, it should have link.h file.
I do have some link.h:

% find android-ndk-r8e -name link.h
android-ndk-r8e/platforms/android-8/arch-arm/usr/include/link.h
android-ndk-r8e/platforms/android-9/arch-arm/usr/include/link.h
android-ndk-r8e/platforms/android-9/arch-mips/usr/include/link.h
android-ndk-r8e/platforms/android-9/arch-x86/usr/include/link.h
android-ndk-r8e/platforms/android-14/arch-arm/usr/include/link.h
android-ndk-r8e/platforms/android-14/arch-mips/usr/include/link.h
android-ndk-r8e/platforms/android-14/arch-x86/usr/include/link.h
android-ndk-r8e/platforms/android-5/arch-arm/usr/include/link.h
android-ndk-r8e/platforms/android-4/arch-arm/usr/include/link.h
android-ndk-r8e/platforms/android-3/arch-arm/usr/include/link.h

but without me knowing why my GCC wrapper does not find any of them. It
could be that the GCC wrapper I used is missing some directories. Just do be
sure that we are understanding each other, please find attached this
wrapper. I have been using since I have started developing on Android:


If you have something else to suggest, I will be glad to test.

I'm not sure to fully understand what you mean here. Should I use the 
-DIGNORE_DYNAMIC_LOADING C compilation option in order to disable dynamic
loading? Is that what you are proposing.

Ah. I will try that (I'm not sure I will find the time to test it this morning). 
Calling GC_INIT() many time is harmless, right?
