Q: cc1: error: unrecognized command line option '-std=c11'

I got this error while compiling cc1: error: unrecognized command line option '-std=c11' a project. All the related issues suggest to use a gcc greater than 4.7 but I already have a gcc greater than 4.7.This is the details gcc version 6.3.0 20170519 (Ubuntu/Linaro 6.3.0-18ubuntu2~16.04) I am t...

@muru I am trying to compile this github.com/rhdunn/espeak/tree/master/android . Issue is happening in this file github.com/rhdunn/espeak/blob/master/android/jni/Android.mk while ndk-build.

@muru Can you please check my edit. I don't know how to make it more clear.This error occured while using 'ndk-build' command.

David Foerster

Where is the MIPS compiler located on your system? What version is it? I'd guess that it's not the same version as /usr/bin/gcc. Also, which build procedure are you using? ndk-build doesn't appear in README.md at all.

@DavidFoerster I am following Android make apk-release is failing with the same error. All the other steps where successfull.MIPS is located here /usr/lib/gcc-cross/mips-linux-gnu with version 5 and 5.4.0 available. gcc is located in /usr/lib/gcc/i686-linux-gnu with version 5,5.4.1,6 and 6.3.0. How to make both same ?

David Foerster

What's your Ubuntu release and how did you install the two GCCs?

What's the output of $CC -c -xc -std=c11 -o /dev/null /dev/null where $CC is the path to your MIPS C compiler?

@DavidFoerster ubuntu is 16.0.4 and I am using a virtualbox. Because of the mentioned error I tried to change my gcc using this gist.github.com/application2000/… and it worked. I tried your command but got these errors.

-vbox:~/eSpeak/espeak-master# /usr/lib/gcc-cross/mips-linux-gnu/5.4.0/cc1 -c -xc -std=c11 -o /dev/null /dev/null     cc1: error: command line option ‘-c’ is valid for the driver but not for C     cc1: error: command line option ‘-xc’ is valid for the driver but not for C

I dont have cc only have cc1.

You shouldn't invoke the cc1 command directly because it doesn't work that way. Please use the related gcc wrapper command instead.

How did you install the MIPS C compiler?

Using this command 'sudo apt-get install gcc-mips-linux-gnu'

@sunilsunny: Then the executable of GCC for MIPS is mips-linux-gnu-gcc. What's the output of mips-linux-gnu-gcc -c -xc -std=c11 -o /dev/null /dev/null?
