I'm trying to build on i386 host, so --disable-debug-symbols is useful to keep memory usage during build low. $ c++ -v FreeBSD clang version 3.4.1 (tags/RELEASE_34/dot1-final 208032) 20140512 Target: i386-unknown-freebsd10.3 Thread model: posix Selected GCC installation: $ pkg install llvm40 $ clang++40 -v clang version 4.0.1 (tags/RELEASE_401/final) Target: i386-portbld-freebsd10.3 Thread model: posix InstalledDir: /usr/local/llvm40/bin $ echo "export CC=clang40 CXX=clang++40 CPP=clang-cpp40" >>.mozconfig $ echo "ac_add_options --disable-debug-symbols" >>.mozconfig $ ./mach bootstrap $ ./mach build [...] /usr/bin/ld: failed to set dynamic section sizes: Memory exhausted clang-4.0: error: linker command failed with exit code 1 (use -v to see invocation) Here's flags used during build: $ ps axd PID TT STAT TIME COMMAND [...] 98159 8 SN+J 0:01.60 | | `-- python2.7 ./mach build 2777 8 IWN+J 0:00.00 | | |-- /usr/local/bin/gmake -f client.mk -s 2843 8 IWN+J 0:00.00 | | | `-- /usr/local/bin/gmake -f /tmp/mozilla-central/client.mk realbuild CREATE_MOZCONFIG_JSON= 2888 8 IWN+J 0:00.00 | | | `-- /usr/local/bin/gmake -j8 -C /tmp/mozilla-central/obj-i386-unknown-freebsd10.3 4536 8 IWN+J 0:00.00 | | | `-- /usr/local/bin/gmake compile 4540 8 SN+J 0:00.04 | | | `-- /usr/local/bin/gmake recurse_compile 4543 8 SN+J 0:00.02 | | | |-- /usr/local/bin/gmake -C js/src target 7387 8 SN+J 0:00.00 | | | | |-- /bin/sh /usr/local/bin/clang++40 -std=gnu++11 -o Unified_cpp_js_src3.o -c -I/tmp/mozilla-central/obj-i386-unknown-freebsd10.3/dist/system_wrappers -include /tmp/mozilla-central/config/gcc_hidden.h -DNDEBUG=1 -DTRIMMED=1 -DENABLE_BINARYDATA -DENABLE_SIMD -DENABLE_WASM_THREAD_OPS -DJS_CACHEIR_SPEW -DENABLE_SHARED_ARRAY_BUFFER -DEXPORT_JS_API -DJS_HAS_CTYPES -DDLL_PREFIX="lib" -DDLL_SUFFIX=".so" -DFFI_BUILDING -DMOZ_HAS_MOZGLUE -I/tmp/mozilla-central/js/src -I/tmp/mozilla-central/obj-i386-unknown-freebsd10.3/js/src -I/tmp/mozilla-central/obj-i386-unknown-freebsd10.3/js/src/ctypes/libffi/include -I/tmp/mozilla-central/js/src/ctypes/libffi/src/x86 -I/tmp/mozilla-central/obj-i386-unknown-freebsd10.3/dist/include -I/tmp/mozilla-central/obj-i386-unknown-freebsd10.3/dist/include/nspr -fPIC -DMOZILLA_CLIENT -include /tmp/mozilla-central/obj-i386-unknown-freebsd10.3/js/src/js-confdefs.h -Qunused-arguments -I/usr/local/include -Qunused-arguments -Wall -Wc++11-compat -Wempty-body -Wignored-qualifiers -Woverloaded-virtual -Wpointer-arith -Wsign-compare -Wtype-limits -Wunreachable-code -Wunreachable-code-return -Wwrite-strings -Wno-invalid-offsetof -Wclass-varargs -Wloop-analysis -Wc++11-compat-pedantic -Wc++14-compat -Wc++14-compat-pedantic -Wc++1z-compat -Wcomma -Wimplicit-fallthrough -Wstring-conversion -Wno-inline-new-delete -Wno-error=deprecated-declarations -Wno-error=array-bounds -Wformat -Wno-gnu-zero-variadic-macro-arguments -Wformat-security -Wno-unknown-warning-option -Wno-return-type-c-linkage -fno-rtti -fno-exceptions -fno-math-errno -pipe -g -O -fno-omit-frame-pointer -Wno-shadow -Werror=format -fno-strict-aliasing -MD -MP -MF .deps/Unified_cpp_js_src3.o.pp -fcolor-diagnostics /tmp/mozilla-central/obj-i386-unknown-freebsd10.3/js/src/Unified_cpp_js_src3.cpp Notice stray -g from MOZ_DEBUG_FLAGS?

Actually passing --disable-optimize rather than assuming it's the > default behavior seems to help. This seems to match Beta and ESR52. Just pass --enable-optimize=-O3

Ah, so that explains why my builders blows again :/

Comment on attachment 8922879 [details] Bug 1412267 - Fix the inclusion of MOZ_DEBUG_FLAGS in the compile command line to depend on MOZ_DEBUG_SYMBOLS and MOZ_DEBUG. I confirm, FreeBSD i386 now builds fine with --disable-debug-symbols.

Comment on attachment 8922879 [details] Bug 1412267 - Fix the inclusion of MOZ_DEBUG_FLAGS in the compile command line to depend on MOZ_DEBUG_SYMBOLS and MOZ_DEBUG. https://reviewboard.mozilla.org/r/194026/#review199622 I'll r+ this even though I'm not the domain expert because you have this all paged in and know what you're doing. One thing I'll ask you to consider is implementing this `MOZ_DEBUG or MOZ_DEBUG_SYMBOLS` in configure. That seems like the better layer for this logic. But I'm not sure what implications that could have. It could certainly be done as a follow-up.
