configu error: C++ compiler cannot create executables
 

Hi,
I have a cross compilation environment inside a chroot.
I run:
i686-unknown-linux-gnu-emerge dev-libs/ace
...
checking for i686-unknown-linux-gnu-g++... i686-unknown-linux-gnu-g++
checking for C++ compiler default output file name... configure:
error: C++ compiler cannot create executables

It seems to me that my toolchain is not complete and the C++ compiler
was not created correctly.

How can I solve this problem?

Regards,
Kfir

Have a look at config.log. It tells exactly what went wrong, including gcc
error output.

It seems that one of the steps that I do, is deleting the tools. I need then to install again from package from the mother system (I'm running here as chroot, and its very good that I did so).

So I install gcc and binutils, then compile them again in the chroot environment.
Using i686-unknown-linux-gnu-emerge and everything happens again.
I didn't find the culprit yet.

Some diagnostics:

Here we see that configure passes the test it failed with emerge.

One line did grab my attention: checking whether we are cross compiling... no

Maybe the environment that i686-gentoo-linux-gnu-emerge creates is not working for ACE.

What do you think?

I did again a cross compilation, really the same way I did before, but with a different name.
crossdev -P -vt i686-gentoo1-linux-gnu
But without the -S, so it compiled all the latest and greatest.


Now the problem is solved, but still ACE will stuck on another line:
checking for epoll_create... configure: error: cannot run test program while cross compiling
See `config.log' for more details.

But this is for different thread.

They're using AC_TRY_RUN(), which is completely ridiculus.

File an upstream report.

I have created an ebuild that deletes the epoll test from configure.
I have posted it here: http://bugs.gentoo.org/show_bug.cgi?id=348521

After eliminating the epoll test, the compilation passes.

Patching autogenerated files is not a good idea - change the
actual source and regenerate.

In the ACE files they ask not to generate configure alone. So I tried it ;) But had problem to finish.
My guess they still tweak by hand.
This is why I went to the auto-generated file. Not the best, but solves the problem for now.*
