So this is a fragment class . I am trying to add some items to listview using baseadaptor. I am a beginner so i followed this question. How to customize listview using baseadapter But now i am getting setcontentview error (Couldn't resolve error) at line no. 72 and inner class error at 147. So please help me in fixing it. package layout;

Solution 1

GCC itself is written in C. Thus, in order to install it, you need a C compiler. This is a catch-22. You're not missing anything. In fact, there is a rather famous Ken Thompson essay, “Reflections on Trusting Trust” reflecting upon a related aspect.

You need to get a C compiler from somewhere. Whoever built your custom distribution surely had one, as you can't build a Linux kernel without it either. They ought to make it available somewhere.

Other than that, you'll have to cross-compile gcc (and binutils, and C library headers, etc.) from a distro where you can install a compiler. This is how someone builds the a distro for a new platform. It's also possible that if your platform is embedded, no one expects you to run gcc on the device itself, and instead they expect you to cross-compile any software you need for the device. In that case, your embedded distro should provide the cross-compiler to use.

Solution 2

I had this exact issue while working with a Ubuntu subsystem within Windows 10 and solved it by doing:

sudo apt-get update 
sudo apt install build-essential

Alternatively, the second command could be more specific:

sudo apt install gcc

Remove setContentView(R.layout.fragment_ussd); in your onCreateView(). You dont need it in a fragment

Why not getting unreachable code after return statement warning

[Pankaj Goyal]

The source code to GCC still needs to be compiled by something, like yacc or some other compiler. Otherwise you're asking how a dictionary can possibly make any sense, what with it using words to define words that are themselves defined by words which are all defined within the dictionary that you can't use if you don't know any words to begin with.

[rici]

@dopeghoti: yacc is not a c compiler

[Pankaj Goyal]

Could have sworn it was Yet Another C Compiler. I stand corrected.

[bucky]

Thanx it fixed @SripadRaj but what about the 2nd error..

[bucky]

inner class cannot have static declaration at the line no. 148

[SripadRaj]

what is line no. 148?

Interesting...I am using a Raspberry Pi, so maybe I will need to cross-compile. I do not have experience with cross-compiling so I will have to look into that. Any idea which dir on my distro a C compiler might be located? Also if I understand your comment correctly, since the reason I wanted to install GCC was so I could use it during the installation of a different piece of software I could just forget about installing GCC and use cross-compiling to install the other software that I need. Is that correct?

[Gerald Murphy]

I am using a Yocto distribution. I don't see anything that looks like a C compiler under /usr/bin/ (I am assuming it would be called something like 'C' 'compile' or 'gcc' but I am not sure.). I will see if I can find a tar for a C compiler.
