@dviktor The website is reset now, it's working, before that, it was 500 http status.

@yeahren just checked - download is fine. Maybe your ISP blocking some sites?

yeahren commented on 2019-02-24 13:22

ERROR: Failure while downloading

and is fine

dviktor commented on 2019-02-13 23:52

Should be fixed now

@dviktor, sorry for the late response. I don't really use gcc6 anymore and unfortunately I don't have the time to look at this. I've transferred maintainership to you. Good luck!

Why is not in the /usr/lib/gcc/x86_64-pc-linux-gnu/6.5.0?

Checking with ldd says that I'm still linked to the /usr/lib/ while needed library is in /usr/lib/gcc/x86_64-pc-linux-gnu/lib

Just compared with community gcc7-libs package - they are moving libraries to the proper place by hand

@berquist you have two options:

1) run export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/gcc/x86_64-pc-linux-gnu/6.5.0 before you execute the program

2) create /etc/ with the following contents:


And then run ldconfig as root, it should be fixed.

Maybe I should add this file to the package but I'm not sure if it may have unintended side-effects.

Something is wrong with the library path for gfortran. Try compiling this program:

      WRITE(*,*) 'Here is some text'
gfortran-6 main.F
$ ldd a.out (0x00007fff153be000) => not found => /usr/lib/ (0x00007f707c647000) => /usr/lib/ (0x00007f707c62d000) => /usr/lib/ (0x00007f707c5ea000) => /usr/lib/ (0x00007f707c426000)
        /lib64/ => /usr/lib64/ (0x00007f707c7fd000)

I spent some time getting gcc6 to build gcj with an complete java 5 environment. A PKGBUILD for a 6.5.0-2 based on 6.5.0-1 is here:

That PKGBUILD builds without issue in a clean chroot for both x86_64 and i686 architectures.

Would it be possible to review these changes and incorporate them into gcc6?

Thanks a lot, unfortunately I have tried these steps and installed different versions of compilers (4.9, 4.9.3, 5, 6.4, 7 etc.) However, MATLAB did not even accept gcc6.4 (from gcc63-multilib). I have edited "mex_C++_glnxa64.xml" and the output is below. Lastly, I also tried to compile 6.3.0 from source but it gives an error called "error 2". Therefore, I am a bit out of options. Is there a way to make this library to give 6.3 version when it requested -dumpversion :)
