brew install gnu-sed gawk binutils gperftools gettext wget help2man libtool autoconf automake
Create a case-sensitive filesystem image:
hdiutil create ~/esp/crosstool.dmg -volname "ctng" -size 10g -fs "Case-sensitive HFS+"
Mount it:
hdiutil mount ~/esp/crosstool.dmg
Create a symlink to your work directory:
cd ~/esp
ln -s /Volumes/ctng crosstool-NG
Download crosstool-NG
and build it:
cd ~/esp
git clone -b xtensa-1.22.x https://github.com/espressif/crosstool-NG.git
cd crosstool-NG
./bootstrap && ./configure --enable-local && make install
Build the toolchain:
./ct-ng xtensa-esp32-elf
./ct-ng build
chmod -R u+w builds/xtensa-esp32-elf
Toolchain will be built in ~/esp/crosstool-NG/builds/xtensa-esp32-elf
. Follow instructions for standard setup <setup-macos-toolchain-add-it-to-path>
to add the toolchain to your PATH
