@dbermond I cannot reproduce that build failure. Do you have changes in your /etc/makepkg.conf? What toolchain are you using? What architecture?
You can always try to add "-fno-lto" in your CFLAGS, which should solve the specific issue you're hitting.
Fails to build for me:
/tmp/ccM7aCZN.s: Assembler messages:
/tmp/ccM7aCZN.s: Error: invalid attempt to declare external version name as default in symbol `__gttf2@@GCC_4.3.0'
lto-wrapper: fatal error: /build/gcc7/src/gcc-build/./gcc/xgcc returned 1 exit status
compilation terminated.
/usr/bin/ld: error: lto-wrapper failed
collect2: error: ld returned 1 exit status

When building on a new install of Arch you'll need to modify your CFLAGS variable in /etc/makepkg.conf and remove the following 3 flags:
-Werror=format-security
-fstack-clash-protection
-fcf-protection
Re-enable the flags after gcc7-libs has compiled.
I adopted the gcc7 packages because I currently use them, but if anyone wants to maintain them please tell me.
I was sure there was a binary version in a repo somewhere in the comments? Is it removed?
@borges staticlibs option is only keeps resulting *.a files in final package. I think there should be more tweaks to the GCC compilation/installation steps to create static versions of libraries
Hi! I'm working on some stuff that requires me to statically link all libraries, including libgfortran, so I compiled this package adding "staticlibs" to the options arrays, but even then I get:
$ gfortran-7 -static -static-libgfortran example.f -o example
/usr/bin/ld: cannot find -lgfortran
collect2: error: ld returned 1 exit status
I searched the yay build dir for gcc7, and there's no libgfortran.a to be found. Am I missing something?
Works perfectly!
