Missing ax_prefix_config_h.m4

[ramrengaswamy]

Installation fails with:
./configure: line 2672: syntax error near unexpected token `proxygen-config.h,'

./configure: line 2672: `AX_PREFIX_CONFIG_H(proxygen-config.h, proxygen, config.h)'

Can be fixed by copying ax_prefix_config_h.m4 to proxygen/proxygen/m4

What autoreconf version do you have? (autoreconf --version)

[ramrengaswamy]

autoreconf (GNU Autoconf) 2.69

[dcsommer]

Very strange. I cannot repro even after a fresh clone. You are using Ubuntu 14.04?

[ramrengaswamy]

Yes. Ubuntu 14.04.

I'm going to leave this open for a while in case anyone else has this issue, but I have not been able to reproduce. If you run into this, please report in this thread.

I have this issue. I show diffs of aclocal.m4 generated by autoreconf. The former (aclocal.m4.saved) is without m4/ax_prefix_config_h.m4 and the latter is with it.

$ diff aclocal.m4.saved aclocal.m4
1258a1259
> m4_include([m4/ax_prefix_config_h.m4])

Possibly you have the file somewhere else. Please check your aclocal.m4.

Sorry, my previous comment was not informative at all. My problem was I'm using CentOS.

Ubuntu 14.04 has autoconf-archive package and it provides /usr/share/aclocal/ax_prefix_config_h.m4, right?

[dcsommer]

@y-uti yes I have that file on my Ubuntu 14.04 install. Although @ramrengaswamy is also using that distro. Do you have /usr/share/aclocal/ax_prefix_config_h.m4 @ramrengaswamy ? Also, have you installed the autoconf-archive package?

[ramrengaswamy]

Looks like I missed autconf-archive package.
Installing it solved the issue.
This issue can now be closed. Sorry about the confusion.
