Попытка собрать crosstool-нг-1.20.0

Question

Моя первая попытка ./configure crosstool-нг выглядит следующим образом:

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 

то бла-бла-бла ...

checking for wget... no 
configure: error: missing required tool: wget 

Конечно, crosstool-ng действительно нужно 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 

ok, сделал символическую ссылку на/usr/bin, и это сделало трюк. Я не удалял префикс wget, чтобы увидеть, предупреждает ли он меня где-то еще ... И я был прав.

configure: WARNING: unrecognized options: --with-wget, --with-gcc, --with-binutils 

Так что я удалил все непризнанные варианты ...

А теперь я просто не могу понять, что не так. Mb gcc? Просто потому, что Wget распознается только в/USR/бен, я думаю скрипта конфигурации не может распознать Gcc префикс тоже, и это выглядит для него в/USR/BIN, где мой компилятор по умолчанию является:

iMac:crosstool-ng-1.20.0 rand$ gcc --version 
Configured with: -- prefix=/Applications/Xcode.app/Contents/Developer/usr 
--with-gxx-include-dir=/usr/include/c++/4.2.1 
Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn) 
Target: x86_64-apple-darwin14.1.0 
Thread model: posix 

но не один из/opt/local/bin

iMac:crosstool-ng-1.20.0 rand$ /opt/local/bin/gcc-mp-4.3 --version 
gcc-mp-4.3 (MacPorts gcc43 4.3.6_10) 4.3.6

Любые мысли?

Answer 1

Это потому, что offsetof() требует stddef.h заголовка на OS X. Там в патч здесь будет убедиться, что он включен:

https://sourceware.org/ml/crossgcc/2014-10/msg00021.html

Для дальнейшего использования, патч:

Применить с использованием patch -p1 :)
