I am using Eclipse Indigo with an Android/NDK mixed project. I’ve added C++ nature and almost everything is working. Automatic builds work; that is, when I edit a file ndk-build is invoked and completes successfully – no build errors. Mouseover code assist works (the little window pops up with information about the function). If I place the cursor on an include line and press F3, a relevant header file open (not the one I would expect based on my configuration, but a relevant one – maybe a clue?).
If I select the following line in my .cpp file, it opens $NDKROOT/platform/android-3/arch-arm/usr/include/ctype.h:
#include <ctype.h>
(isdigit is defined in this file)
However, Eclipse insists that isdigit is not defined. I have read many posts suggesting that either the static analyzer or the indexer is to blame, but I’ve tried many of the suggested solutions to no avail.
If I add a line like the following, the error goes away and mouseover code assist for the function works:
extern int isdigit(int);
Again, this is not a linker error or a compiler error – ndk-build completes with no errors. This is something inside eclipse. Thanks for taking a look!
Edit: I now believe this to be a Code Analysis problem. A better solution is to edit the Code Analysis options to make “Function could not be resolved” be a warning instead of an error. That way you can see the warnings in Problems view, but continue to work. If the function is REALLY missing, the compiler will tell you! I also have a new theory, that the problem is with the Code Analyzer following symlinks, because all of the “missing” functions are in symlinked include files. Would love any input on this theory.
I worked around this issue via the approach I suggested in my question and haven’t been able to find a better way yet.
