试图编译crosstool-ng-1.20.0

标签： cross-compiling toolchain crosstool-ng

我第一次尝试./configure crosstool-ng看起来像这样：

 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
然后bla-bla-bla ...... 

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

当然，crosstool-ng确实需要wget。但它很奇怪，因为我拥有它！

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

好的，对/ usr / bin做了符号链接，这就是诀窍。我没有删除wget前缀只是为了看它是否警告我在其他地方......我是对的。 

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

所以我删除了所有无法识别的选项......

现在我无法解决错误。 Mb gcc？仅仅因为wget只在/ usr / bin中被识别，我认为配置脚本也不能识别gcc前缀，它在/ usr / bin中查找，我的默认编译器是：

 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

但不是/ opt / local / bin

中的那个 
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

有什么想法吗？

这是因为offsetof()在OS X上需要stddef.h标题。这里有一个补丁，可以确保它包含在内：

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

为了将来参考，补丁是：

diff --git a/kconfig/zconf.gperf b/kconfig/zconf.gperf
index c9e690e..d758a2a 100644
--- a/kconfig/zconf.gperf

 struct kconf_id;

 static struct kconf_id *kconf_id_lookup(register const char *str, register unsigned int len);

使用patch -p1申请：）
