'new' undeclared (first use in this function)

[murkser]

Hi!

I am quite new to the android-ndk.
For this line

str = new char[50];

I get the " 'new' undeclared (first use in this function) "-Error. I
thought C++ is supported?
Thank you for your help.

Looks like you're building as C. What's your file extension?

I have two files in this project.
The file with the function I want to use in java has *.c (with *.cpp I
get an error here)
In this file I start a function from another file (*.cpp) where I want
to put my C++ code (including str = new char[50]; )

new is a keyword in C++. If the file in question is being built as C++,
there is no way for "new" to be undefined; you can get link errors if it
can't find the proper library, though. Are you saying that the "new
char[50]" appears in a .cpp file? And that the .cpp file is being
included in Android.mk as part of LOCAL_SRC_FILES?

What is the exact error message you're getting? And what does the
compile line look like when you run:

ndk-build V=1

...to get a verbose build?

is the cpp extension defined correctly in your make file?

I declared everything as .cpp and now it works. Thanks for your help.
