Question

当尝试安装使用本机扩展的ruby gem时，我的安装失败。

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

日志文件给出了以下输出

"gcc-mp-4.9 -o conftest -I/Users/bigtunacan/.rvm/rubies/ruby-1.9.3-p551/include/ruby-1.9.1/x86_64-darwin13.4.0 -I/Users/bigtunacan/.rvm/rubies/ruby-1.9.3-p551/include/ruby-1.9.1/ruby/backward -I/Users/bigtunacan/.rvm/rubies/ruby-1.9.3-p551/include/ruby-1.9.1 -I. -D_XOPEN_SOURCE -D_DARWIN_C_SOURCE   -I/opt/local/include  -O3 -ggdb -Wall -Wextra -Wno-unused-parameter -Wno-parentheses -Wno-long-long -Wno-missing-field-initializers -Wpointer-arith -Wwrite-strings -Wdeclaration-after-statement -Wimplicit-function-declaration  -fno-common -pipe conftest.c  -L. -L/Users/bigtunacan/.rvm/rubies/ruby-1.9.3-p551/lib -L/opt/local/lib -L.  -L/opt/local/lib      -lruby.1.9.1  -lpthread -ldl -lobjc "
checked program was:
/* begin */
1: #include "ruby.h"
2: 
3: int main(int argc, char **argv)
4: {
5:   return 0;
6: }
/* end */

看来这是在寻找gcc的macports版本，而不是使用系统gcc，但我甚至没有在系统上安装任何macports gcc。

------编辑从gem_make.out文件添加输出---------

最终在rvm宝石集的rbconfig.rb文件中gcc设置是粘滞的。

我不得不去

new Document("Document.Details.Id":id);
new Document("Details.Id":id);
new Document("Document.Id":id);

我必须改变

~/.rvm/rubies/ruby-1.9.3-p551/lib/ruby/1.9.1/x86_64-darwin13.4.0/rbconfig.rb

到

CONFIG["CC"] = "gcc-mp-4.9"

并且还要改变

CONFIG["CC"] = "gcc"

到

CONFIG["configure_args"] = " '--prefix=/Users/bigtunacan/.rvm/rubies/ruby-1.9.3-p551' '--with-opt-dir=/opt/local' '--without-tcl' '--without-tk' '--disable-install-doc' '--enable-shared' 'CC=gcc-mp-4.9'"
