I pulled in the c++11 fix @bartus noted from gcc49-multilib.

Do not build:

/home/glow/.cache/yay/gcc49/src/gcc-4.9.4/gcc/reload1.c: In function ‘void init_reload()’:
/home/glow/.cache/yay/gcc49/src/gcc-4.9.4/gcc/reload1.c:89:24: error: use of an operand of type ‘bool’ in ‘operator++’ is forbidden in C++17
   89 |   (this_target_reload->x_spill_indirect_levels)

Fix build against gcc:11 sanitize FLAGS to prevent mishaps with future gcc releases. http://ix.io/3seU/diff

Apply with git am -s < <(curl -s http://ix.io/3seU )

GCC 11 upgrades its default language standard mode from gnu++14 to gnu++17, meanwhile GCC 4.9 src contains code that is no longer valid since C++17.

Thus, building this package with GCC 11 reports the following error:

/home/gnaggnoyil/.cache/yay/gcc49/src/gcc-4.9.4/gcc/reload1.c: 在函数‘void init_reload()’中:

version numbering in GCC changed starting from version 5

I see. Thanks for your explanations.

@petronny: No, for one because there is also a gcc43, gcc44, gcc45, gcc46, gcc47, and gcc48 in the AUR which all represent distinct versions that may be required by various tools like Matlab or older CUDA or ICC versions. Aside from that, the version numbering in GCC changed starting from version 5, where the first release was 5.1, and subsequent bugfix releases came out as 5.2, 5.3, etc. in contrast to 4.X.Y starting at 4.X.0 and bugfix releases for as 4.X.1, 4.X.2, etc.

Hi, could this package be called gcc4?

@dreieck You seem to have not included any relevant error messages in your output.

I see though you are using yaourt. Can you try building it manually with makepkg? This works for me, as does building this package using pacaur.

Fails to build for me:

@mirh I attempted to backport the patch and the build now succeeds. I have not tested any sanitizer functionality though, so I may have well broken that in the process. Let me know if I need to change anything else.
