Building libgcc cross compiler error: cannot compute suffix

[tetra]

Hello everyone,

I've searched all over internet how to solve libgcc error when building cross compiler.
But none of them didn't help to solve my problem.

The os that I'm using is ubuntu 14.04.
The versions that I use to create cross compiler are:
gcc 4.9.0
binutils 2.9.1
gmp 6.0.0
mpfr 3.1.2
mpc 1.0.2

Errors that I get.

I don know if this has somthing to do with the error, but binutils gave also an error.

$> make install

------------------------------------------------------------------------------
Libraries have been installed in:
/home/test/opt/cross/lib

To link against installed libraries in a given directory, LIBDIR,
you must use the `-LLIBDIR' flag during linking.

You will also need to do one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

binutils 2.9.1

1998 was a long time ago. Why don't you try a newer version? I believe 2.24 is the latest.

It looks like there are several problems to solve here. The thing with 2.9 is that it's known not to build, and that whoever still uses it didn't actually read the tutorial properly because versions are mentioned repeatedly. Also, the fact that you forcibly continued after the first error indicates some prior experience issues.

Try to apply a bit more scrutiny to your own work, and also consider to what extent the "Required Knowledge" rule applies to you - you might want to read up on several other thing you are likely to encounter sometime soon.

Thanks Octocontrabass, that did the trick.
