Попытка скомпилировать crosstool-ng-1.20.0
Моя первая попытка./configure crosstool-ng выглядела так:
iMac:crosstool-ng-1.20.0 rand$ ./configure --prefix=/opt/local
--with-libtool=/opt/local/bin/glibtool
--with-libtoolize=/opt/local/bin/glibtoolize
--with-objcopy=/opt/local/bin/gobjcopy
--with-objdump=/opt/local/bin/gobjdump
--with-readelf=/opt/local/bin/greadelf
--with-awk=/opt/local/bin/gawk
--with-sed=/opt/local/bin/gsed
--with-automake=/opt/local/bin/automake
--with-wget=/opt/local/bin/wget
--with-gcc=/opt/local/bin/gcc-mp-4.3
--with-binutils=/opt/local/bin
тогда бла-бла-бла...
checking for wget... no
configure: error: missing required tool: wget
конечно, crosstool-ng нужен wget. Но это странно, потому что у меня это есть!
iMac:crosstool-ng-1.20.0 rand$ ls -l /opt/local/bin |grep wget
-rwxr-xr-x 1 root admin 499672 Mar 1 00:39 wget
Хорошо, сделал символическую ссылку на / usr / bin, и это помогло. Я не удалил префикс wget только для того, чтобы посмотреть, предупреждает ли он меня где-то еще... И я был прав.
configure: WARNING: unrecognized options: --with-wget, --with-gcc, --with-binutils
Поэтому я удалил все нераспознанные варианты...

И теперь я просто не могу понять, что не так. Мб гкц? Просто из-за того, что wget распознается только в / usr / bin, я думаю, что скрипт configure не может распознать префикс gcc, и он ищет его в / usr / bin, где мой компилятор по умолчанию:

Какие-нибудь мысли?

Это потому что offsetof() требует stddef.h заголовок на OS X. Есть патч здесь, чтобы убедиться, что он включен:

Для дальнейшего использования патч:
