Odp: Re: GNUstep on Android

[Enry the Ermit]

I made a start on a macos brew script based on yours. You can fetch it here :

Hi Ivan,

 

first of all, thanks for sharing your work. I think I understand what

you did, nevertheless following your instructions with just two changes

(see below), I get an error at the very last step that until now I don't

understand (mainly because I don't see where it comes from).

I made two small changes: I added the following parameters to the

configure call of gnustep make:

 

--enable-objc-nonfragile-abi --with-layout=gnustep

 

and the following one to the configure call of gnustep base:

 

--disable-mixedabi

 

I don't know if they are still needed nowadays, but at least (especially

because of the old compiler used - clang 3.3) I wanted to make sure that

this won't create problems. Nevertheless the error in the last step

happened also when I omitted these changes.

 

I consider the results a bit "creepy", as "make install" will put

Android binaries to places where X86 binaries belong, but for the time

being I can ignore this. I assume that for a proper cross compiling we

need to set up a kind of "sysroot" where e.g. GNUstep and libobjc2 get

installed to and where other libraries can find them.

 

When I build gnustep base, it seems that the exception handling is not

detected properly:

 

> ../../Headers/Foundation/NSException.h:48:2: error: "gnustep-base is configured to use 'traditional' exceptions, but you are

>       building for 'native' exceptions."

> #error  "gnustep-base is configured to use 'traditional' exceptions, but you are building for 'native' exceptions."

 

Having a look into the configure output, I detected several scary

warnings, so all in all I don't think that this is usable now. I will

continue to investigate this.

 

Regards,

Mathias
