--------------------------------------
Resolution: Fixed
> errno extern variable redefined. Not compiling for Android
> ----------------------------------------------------------
>
> Key: THRIFT-3370
> URL: https://issues.apache.org/jira/browse/THRIFT-3370
> Project: Thrift
> Issue Type: Bug
> Components: C glib - Library
> Affects Versions: 0.9.3
> Reporter: Gonzalo Aguilar
> Labels: build, c, easyfix
>
> It seems that the definition of errno we are using on the c_glib transport is
> not 100% correct. While it's ok for ISO C99 compilers it fails under Android.
> My opinion is that Android is behaving incorrectly here but I cannot be sure
> until I check with you.
> In the thrift_socket.c an thrift_server_socket.c implementations there's a
> errno variable declared.
> /* for errors coming from socket() and connect() */
> extern int errno;
> This variable is redefined in the ndk of the in the file
> arch-arm/usr/include/errno.h
> I don't know why.
> /* a macro expanding to the errno l-value */
> #define errno (*__errno())
> So the compilation fails because redefined.
> Commenting out the extern definition on these files it compiles, it was
> tested and it works. But I don't know how this can work since the definition
> of errno on the files change from int to pointer.
> Can someone comment this please?
