This issue might suffer any binary distribution sooner or later, be it Fedora, Debian or even Homebrew on Mac. The only case where it doesn't really matter is when you build everything from scratch on the target system, because there you have the whole toolchain and it is run only on that specific environment. Actually it would have never be issue if the ```-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1``` option, which pulls in some configuration file, was not among the parameters. ---------------------------------------- Bug #14422: Ruby configuration options should not be reused for gem builds https://bugs.ruby-lang.org/issues/14422#change-70112 * Author: vo.x (Vit Ondruch) * Status: Open * Priority: Normal * Assignee: * Target version: * ruby -v: ruby 2.5.0p0 (2017-12-25 revision 61468) [x86_64-linux] * Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN ---------------------------------------- When Fedora started to harden its packages, we quite often seen complains from our users about problems installing their gems, with errors such as [1]: ~~~ gcc: error: /usr/lib/rpm/redhat/redhat-hardened-cc1: No such file or directory ~~~ The issue as analyzed by Mamoru TASAKA is [2]: > Well, if I am not mistaken, the real problem here is that rpm's %optflags is always embedded into Fedora's ruby config file, that is > > /usr/lib64/ruby/rbconfig.rb:167: CONFIG["CXXFLAGS"] = "-O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -mtune=generic" > /usr/lib64/ruby/rbconfig.rb:171: CONFIG["CFLAGS"] = "-O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -mtune=generic -fPIC" > > on x86_64, for example. > > Although I am not sure this is already discussed somewhere or not, basically I think changing the default CFLAGS of "system" ruby like this way is undesirable and ? installed "rbconfig.rb" should have some "minimal" CFLAGS / CXXFLAGS. > ( for example, just like CONFIG["CFLAGS"] = "-fPIC" ) > > Only when we build Fedora gems or so (on koji), we should change CFLAGS / CXXFLAGS explicitly afterwards using %optflags. and Red Hat toolchain team responds [3]: > The current advice of the Red Hat toolchain team is to keep distribution build flags and toolchain default flags separate. This is why running “gcc” gives you the upstream defaults, and not the flags we use to compile Fedora packages. For consistency, Ruby (and other compilation support tools) follow this pattern: Use distribution flags when building for Fedora, but use upstream flags when the user compiles packages (i.e., what Ruby uses, probably something involving -O2). > > Our build flags are fully ABI-compatible with each other, so mismatches will not cause any problems at the C/C++/ABI level. The question is why Ruby does this and how we can avoid this behavior. We could force installation of redhat-rpm-config package, providing the "/usr/lib/rpm/redhat/redhat-hardened-cc1", to every ruby user, but that does not seems right. There are also other similar issues discussing this situation [4], [5]. Any thoughts?
