When firefox is built with ROOT= and PORTAGE_CONFIGROOT=$ROOT where $ROOT has -march=... and the build process is on a different machine which is binary incompatible to the machine on which $ROOT is suppose to the transferred, this error occurs. It seems in the build process, firefox executes some binaries which was build using ROOT's -march=.... which results in -- traps: TaskCon~ller #5[195099] trap invalid opcode ip:7f6128f38686

I think I've mentioned this on your bugs before, but maybe not: I'll note that at least for some build systems, unless it can "see" you're doing cross with e.g. different CHOST (some even actually check uname or something, very icky), they may take different paths and do things like this.

Only crossdev is changing the CHOST. The middle part which must be user configurable has changed. If I use the middle part as 'pc' -- then it'll overwrite the toolchain in my host machine. So I'm not sure what to do here (even as per the manuals) Note both the ROOT and build host are x86-64
My point was really just that ROOT= on the same architecture often means build systems don't realise they're doing cross and do silly things, and you may run into other instances like this. Doesn't mean it's wrong to try, just that some assumptions like this might be a pain to try fix in custom build systems.
Ok. So I'll try changing the CHOST too along with ROOT (with the one which crossdev sets) and see what happens.
Ok, that failed immediately, but do you suggest I change the CHOST to something which crossdev would otherwise set and follow https://www.gentoo.org/doc/en/change-chost.xml?
If you are changing the middle part, then the CHOST inside the ROOT is already different to the one outside, and you need to see why Mach thinks that it's okay to do what it's doing (does it have a cross-compilation mode at all?)
Currently it's the same. I'll do that and check after rebuilding world.
(In reply to dE from comment #6) > Ok, that failed immediately, but do you suggest I change the CHOST to > something which crossdev would otherwise set and follow > https://www.gentoo.org/doc/en/change-chost.xml? I just changed that from the environment variable and the build failed. So I guess I need to follow https://www.gentoo.org/doc/en/change-chost.xml.
Created attachment 911791 [details] Failed build log with cross-toolchain. In this build log (unlike the previous one) you can see -- checking whether cross compiling... yes But STILL the build is resulting in the same issue (invalid opcode). Cross compilation was achieved by setting the CHOST != CBUILD.
OP seems to be running PGO which tries to execute the newer binaries on the older instruction set CPU: https://forums.gentoo.org/viewtopic-t-1170684.html ``` USE="...pgo ..." ```
(In reply to Georgi from comment #11) Thanks, that's a very helpful observation.
Thanks, definitely. Isn't this just impossible to fix then? We could add a die if PGO and non-empty ROOT, I guess, but..
(In reply to Sam James from comment #13) > Thanks, definitely. Isn't this just impossible to fix then? We could add a > die if PGO and non-empty ROOT, I guess, but.. I don't think that would be good. Someone might be building for the same arch and CPU and PGO could actually run fine unless I understand it wrong. Maybe only a warning. This becomes too much for portage/ebuilds to handle I think plus Gentoo is for advanced users. This matter goes well beyond the responsibilities of a package manager and into the competencies of the user. Best Regards, Georgi
