I highly recommend building this package in a clean chroot. This avoids the use of a AUR helper, which sometimes uses /tmp as the stating directory, which often gets filled completely by gcc's build process.

It also provides a clean environment, which minimizes interactions between your current environment and gcc's build process.

Does this package include gcc 6.3.x? I have installed this but it shows 6.5 and MATLAB, unfortunately, does not accept this version. Yet, I am unable to find 6.3.x. Does anyone know how I can install 6.3.x?

sokuban you can use pacman -U with --overwrite option

I could build fine (I needed at least 8GiB though), but I can't install the resulting packages. I looked at the conflicting files, and most of them seem to be the same size, but the size of the two libstdc++.a are different.

Any advice?

[code]$ sudo pacman -U gcc6-6.4.1-8-x86_64.pkg.tar.xz gcc6-fortran-6.4.1-8-x86_64.pkg.tar.xz gcc6-gcj-6.4.1-8-x86_64.pkg.tar.xz gcc6-libs-6.4.1-8-x86_64.pkg.tar.xz loading packages... resolving dependencies... looking for conflicting packages...

Unfortunately (or fortunately) I can no longer reproduce the build failure.

just built it, 7.6G required disk space (ext4) in total

lonaowna commented on 2018-08-28 07:52 (UTC)

@wjmelements can you post your entire build log?

wjmelements commented on 2018-08-27 23:44 (UTC)

When I try to build, I always get a link-time error when linking cc1. Unfortunately there isn't a descriptive error message.

g++ -std=gnu++98 -no-pie .  -g -DIN_GCC .   -fno-exceptions -fno-rtti -fasynchronous-unwind-tables -W -Wall -Wno-narrowing ..........  -Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now -o cc1 c/c-lang.o c-family/stub-objc.o attribs.o .................... -lisl -lmpc -lmpfr -lgmp -rdynamic -ldl -lz
collect2: error: ld returned 1 exit status

I am also seeing warnings about not compiling with optimization

# . warning _FORTIFY_SOURCE requires compiling with optimization (-O)

When I built without yaourt, I don't get the optimization warnings but it got into an infinite loop that lasted until my disk filled up several hours later.

With application of the patch from here I was also able to compile it.

Best regards, EndruK

@EndruK @TheEbolaDoc the glibc 2.28 build issues should be fixed in 6.4.1-8. Let me know if you still experience problems.
