error in configure file

[itssivashankar]

Hi,
I am trying to build json-c using (./congigure) command i am getting this error on coreos.
so, kindly help me to solve this error

./configure: line 12361: syntax error near unexpected token -Wall' ./configure: line 12361: AX_APPEND_COMPILE_FLAGS(-Wall -Werror -Wcast-qual -Wno-error=deprecated-declarations)'

What version of the code are you using? If you're using a release tarball or branch, that error shouldn't be possible. If you're using the most recent code from the master branch, you need to make sure you have a recent enough version of autoconf and automake. See https://github.com/json-c/json-c/blob/master/README.md

i am using the latest version autoconf(2.69)

So you get:

$ autoreconf --version | head -1
autoreconf (GNU Autoconf) 2.69
$ automake --version | head -1
automake (GNU automake) 1.15

? hmm... Did you see any errors when you ran autogen.sh ?

[itssivashankar]

their is no error on autogen.sh i am getting error only on the configure file
can you tell me what is the reason for the error

./autogen.sh is how configure is generated. Your error looks like you just renamed configure.ac to configure and tried to run it.

If you downloaded a release tarball it should have had a properly generated configure in it, but if you cloned the git repo, or downloaded a tarball generated by github, it would be lacking the configure script, and you would have to run ./autogen.sh to generate it, and you would need new-enough versions of autoconf and automake.

I think it's more complicated than just renaming the configure.ac script, look at the line number of the error. You'd get the error that itssivashankar sees if the autoconf-archive/m4 directory is missing, or if the AC_CONFIG_MACRO_DIRS isn't working properly. That macro wasn't available with too early of a version of automake, and he still hasn't told us what version of that he is using, so my guess is that it's too old to work.

[ploxiln]

yeah that makes more sense

Hi Ploxiln,

This post saved my day! I was banging my head why 'configure' file is available in release tar ball not in git clone.

Thank you very much!!

There doesn't seem to be anything that needs to be fixed in json-c here, closing.
