Fail compiling firefox with compiler toolchain in non-standard location

已張貼

I am trying to build firefox version 68.0 from source using the following options: ```

  1. Set up the config options

export MOZCONFIG=`pwd`/mozconfig cat > mozconfig << EOF mk_add_options MOZ_MAKE_FLAGS="-j4"

  1. If you have installed dbus-glib, comment out this line:
  2. ac_add_options --disable-dbus
  1. If you have installed dbus-glib, and you have installed (or will install)
  2. wireless-tools, and you wish to use geolocation web services, comment out
  3. this line

ac_add_options --disable-necko-wifi

  1. API Keys for geolocation APIs - necko-wifi (above) is required for MLS
  2. Uncomment the following line if you wish to use Mozilla Location Service
  3. ac_add_options --with-mozilla-api-keyfile=$PWD/mozilla-key
  1. Uncomment the following line if you wish to use Google's geolocaton API
  2. (needed for use with saved maps with Google Maps)
  3. ac_add_options --with-google-api-keyfile=$PWD/google-key
  1. Uncomment this line if you have installed startup-notification:
  2. ac_add_options --enable-startup-notification
  1. Uncomment the following option if you have not installed PulseAudio

ac_add_options --disable-pulseaudio

  1. and uncomment this if you installed alsa-lib instead of PulseAudio

ac_add_options --enable-alsa

  1. If you have installed GConf, comment out this line

ac_add_options --disable-gconf

  1. The BLFS editors recommend not changing anything below this line:

ac_add_options --prefix=/scratch/local/firefox-68.0 ac_add_options --enable-application=browser

ac_add_options --disable-crashreporter ac_add_options --disable-updater

  1. enabling the tests will use a lot more space and significantly
  2. increase the build time, for no obvious benefit.

ac_add_options --disable-tests

  1. Optimization for size is broken with gcc7 and later

ac_add_options --enable-optimize="-O2"

ac_add_options --enable-official-branding

  1. From firefox-61 system cairo is not supported

ac_add_options --enable-system-ffi ac_add_options --enable-system-pixman

  1. From firefox-62 --with-pthreads is not recognized

ac_add_options --with-system-bz2

  1. ac_add_options --with-system-jpeg
  2. ac_add_options --with-system-png

ac_add_options --with-system-zlib

mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/firefox-build-dir EOF

```

./mach build failed with the errors:
