Source: mozjs91 Version: 91.10.0-1 Severity: serious Tags: ftbfs help X-Debbugs-Cc: debian-arm@lists.debian.org Control: block 1017961 by -1
Versions of mozjs91 newer than 91.10.0-1 failed to build on the armel buildds. I tried building 91.10.0-1 in an armel chroot on amdahl, and that also fails, which makes me think that the root cause for the build failure is the upgrade from gcc 11 to 12 as default compiler. The final link fails with multiple definitions of the various atomic builtins: > /usr/bin/arm-linux-gnueabi-g++ -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 > -fstack-protector-strong -Wdate-time -D_FORTIFY_SOURCE=2 -Wall -Wempty-body > -Wignored-qualifiers -Wpointer-arith -Wsign-compare -Wtype-limits > -Wunreachable-code -Wno-invalid-offsetof -Wc++2a-compat -Wduplicated-cond > -Wimplicit-fallthrough -Wno-error=maybe-uninitialized > -Wno-error=deprecated-declarations -Wno-error=array-bounds > -Wno-error=coverage-mismatch -Wno-error=free-nonheap-object > -Wno-multistatement-macros -Wno-error=class-memaccess > -Wno-error=deprecated-copy -Wno-error=unused-but-set-variable -Wformat > -Wformat-overflow=2 -Wno-psabi -fno-sized-deallocation -fno-aligned-new -g > -O2 -ffile-prefix-map=/home/smcv/mozjs91-armel=. -fstack-protector-strong > -Wformat -Werror=format-security -fPIC -fno-rtti -ffunction-sections > -fdata-sections -fno-exceptions -fno-math-errno -pthread -pipe -g > -freorder-blocks -O3 -fomit-frame-pointer -funwind-tables -shared > -Wl,-z,defs -Wl,--gc-sections -Wl,-h,libmozjs-91.so -o libmozjs-91.so > /home/smcv/mozjs91-armel/debian/build/js/src/build/libmozjs-91_so.list > -lpthread -Wl,-z,relro -Wl,-z,noexecstack -Wl,-z,text -Wl,-z,relro > -Wl,-z,nocopyreloc -Wl,-Bsymbolic-functions -Wl,--build-id=sha1 > -fstack-protector-strong > -Wl,-rpath-link,/home/smcv/mozjs91-armel/debian/build/dist/bin > -Wl,-rpath-link,/usr/lib > /home/smcv/mozjs91-armel/debian/build/armv5te-unknown-linux-gnueabi/release/libjsrust.a > -Wl,--version-script,symverscript -Wl,-soname,libmozjs-91.so.0 -lm > -latomic -lz -lm -ldl > /usr/bin/ld: /usr/lib/gcc/arm-linux-gnueabi/12/libgcc.a(linux-atomic.o): in > function `__sync_fetch_and_add_4': > (.text+0x0): multiple definition of `__sync_fetch_and_add_4'; > /home/smcv/mozjs91-armel/debian/build/armv5te-unknown-linux-gnueabi/release/libjsrust.a(compiler_builtins-23c2fc8f8ef06d87.compiler_builtins.bdb7b41d-cgu.153.rcgu.o):/usr/src/rustc-1.59.0/vendor/compiler_builtins/src/arm_linux.rs:94: > first defined here > /usr/bin/ld: /usr/lib/gcc/arm-linux-gnueabi/12/libgcc.a(linux-atomic.o): in > function `__sync_fetch_and_sub_4': > (.text+0x38): multiple definition of `__sync_fetch_and_sub_4'; > /home/smcv/mozjs91-armel/debian/build/armv5te-unknown-linux-gnueabi/release/libjsrust.a(compiler_builtins-23c2fc8f8ef06d87.compiler_builtins.bdb7b41d-cgu.153.rcgu.o):/usr/src/rustc-1.59.0/vendor/compiler_builtins/src/arm_linux.rs:94: > first defined here (etc.) An example build log: https://buildd.debian.org/status/fetch.php?pkg=mozjs91&arch=armel&ver=91.13.0-1&stamp=1661218081&raw=0 The same failure mode occurred when I tried to build mozjs102 with ARMv7 inline assembler disabled for #1017961. (For completeness: 91.10.0-1 and 91.12.0-1 have an additional failure reason involving undefined references to std::type_info::operator==(std::type_info const&) const, but I believe that was fixed in 91.12.0-2 by removing an obsolete patch. The latest mozjs91 and mozjs102 do not have the obsolete patch and do not exhibit the std::type_info errors.) Assistance from fans of armel would be much appreciated. If we cannot get mozjs102 to compile on armel, then gjs and the GNOME stack in general will probably have to be removed from armel, similar to the way we temporarily removed them from s390x between mid 2019 and mid 2020. smcv
