C compiler not found?? But... It's there!

[Hoch]

Hi,

I'm trying to compile pagespeed nginx dynamic module but I got the following error 'checking for C compiler ... not found'

As you can see below, I have gcc-mozilla installed in the correct path.

Any suggestions?

Thank you!

Did configure leave behind a config.log or anything? I think it's mostly likely that the binary was built but then failed to run, but it's hard to tell without a bit more information.

Steve,

Thank you for your answer.

No config.log in the nginx directory... Nor in any other directory.

Compiler is in the right place.

Any clues?...

Thanks!

Hi,

If I use the gcc v4.9 I had installed in my system, instead of gcc-mozilla, compilation starts but aborts with errors. This is what I get in the terminal and in autoconf.err:

gcc-4.9: error trying to exec 'cc1plus': execvp: No such file or directory

That looks like you don't have the c++ portion of gcc installed, it's
usually a different package.
Since you mentioned gcc-mozilla, you might be on Ubuntu; there the
relevant package is probably g++-4.9

Also: autoconf.err is probably where you'll find errors to help debug the gcc-mozilla problems. Sorry.

Hi,

Thank you Maksim and Steve for taking the time to guide me through this C maze... :-)

Below is the autoconf.err after compiling whith gcc-mozilla.

Seems that there are problems with crt1.o object file?

I have experience with compilers but not with C, so no idea of what this means...

Thank you for your patience!
