Bootstrap failure #18

Closed rhdtownsend closed 6 months ago

rhdtownsend commented 7 months ago

I'm trying to build 13.2 on MacOS 14.4.1. I applied the patch at

https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=9970b576b7e4ae337af1268395ff221348c4b34a

...but run into the following bootstrap failure:

rm -f stage_current Comparing stages 2 and 3 Bootstrap comparison failure! aarch64-apple-darwin20/libstdc++-v3/src/.libs/libstdc++.6.dylib-master.o differs make[2]: [compare] Error 1 make[1]: [stage3-bubble] Error 2 make: *** [all] Error 2 FAILED in make for gcc Action install failed for package gcc/gcc-13.2-darwin

This is with CLT 15.3, and configuring with the following:

/opt/sdk2-tmp/build/gcc/configure CC=clang CXX=clang++ --build=aarch64-apple-darwin20 --host=aarch64-apple-darwin20 --target=aarch64-apple-darwin20 --prefix=/opt/sdk2-tmp/mesasdk --with-gmp=/opt/sdk2-tmp/mesasdk --with-mpfr=/opt/sdk2-tmp/mesasdk --with-mpc=/opt/sdk2-tmp/mesasdk --enable-languages=c,c++,fortran --disable-multilib --disable-nls --disable-libsanitizer --with-sysroot=/opt/sdk2-tmp/mesasdk/sysroot --without-build-config

there are a number of issues with changes in the macOS 14 and CLT.

I believe they are solved in the current 13.3 pre-release branch (https://github.com/iains/gcc-13-branch/tree/gcc-13-3-darwin-pre-0) if you would like to try that [noting that it will be force-pushed / rebased and mostly unsupported until it becomes the 13-3-darwin branch]. I suspect that, because 13.3 is likely not far in the future (june or so) it will not be considered worth trying to do another 13.2 release.

I've just tried the pre-release branch, and I still get the same error. However, the errors go away (on pre-release and on patched 13.2) if I remove the --without-build-config flag (which I started adding a few releases ago, to work around a different issue). So, probably a false alarm on my part.

Aha ... you reminded me I was intending to ask why that was there - it's a odd one; I will have to see what is expected to happen there. My general rule of thumb is "don't add configure options unless there's a clear reason and an explanation of the effect of the change" .. there are simply too many to test (yet another combinatorial test matrix explosion)

iains commented 7 months ago

note: that there are still issues with the 13.2 release + macOS14 + CLT15 (many test fails because of increased linker diagnostics, for one).

iains commented 7 months ago

Those should be fixed with the 13.3 release when it comes and the 14.1 branch which should be released during May.

iains commented 6 months ago

fixed in 13.3-darwin-r0
