从根源分析，调试，定位和解决MacOS ld: unsupported tapi file type ‘!tapi-tbd‘ in YAML file

    你要是遇到同样错误，找一圈都没有解决，建议认真读一下本文，这个应该是最终极的解决办法，从原理上剖析了产生的原因，同时给出来了调试和定位的办法。

    maccos使用brew安装了一个gcc14, 结果编译一个最简单的程序都报错，如下：

gcc-14 test.c -o t
ld: unsupported tapi file type '!tapi-tbd' in YAML file '/Library/Developer/CommandLineTools/SDKs/MacOSX11.sdk/usr/lib/libSystem.tbd' for architecture x86_64
collect2: error: ld returned 1 exit status

        查了网上是说libSystem.tbd和ld不一致引起的。现在不知道ld是调用了哪份，当前系统一堆不同版本的。

      一般的解决办法如下：

      

sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

        但是我试了并没有用，同时使用clang编译是正常的，说明这个CommandLineTools没有问题的。

       没有办法了，只好自己来分析一下了。

        首先使用 dtruss跟踪一下系统api调用，发现ld应该是posix_spawn调用了。如下：

sudo dtruss gcc-14 test.c -o t

发现是最后一个apiposix_spawn是调用/usr/local/Cellar/gcc/14.2.0_1/bin/../libexec/gcc/x86_64-apple-darwin20/14/collect2

运行一下 它加一个-debug参数

 /usr/local/Cellar/gcc/14.2.0_1/bin/../libexec/gcc/x86_64-apple-darwin20/14/collect2    -debug  
//...去掉一堆
Looking for 'gcc'
collect2 version 14.2.0
ld_file_name        = /usr/local/anaconda3/bin/ld
c_file_name         = /usr/bin/gcc
nm_file_name        = /usr/local/anaconda3/bin/nm
strip_file_name     = /usr/local/anaconda3/bin/strip
c_file              = a.out.cdtor.c
o_file              = a.out.cdtor.o

看起来是使用了 /usr/local/anaconda3/bin/ld 我晕。

这个一堆都使用了这个目录下的，先临时屏蔽一下，

mv  /usr/local/anaconda3/bin  /usr/local/anaconda3/bin.bak

再执行

 /usr/local/Cellar/gcc/14.2.0_1/bin/../libexec/gcc/x86_64-apple-darwin20/14/collect2    -debug  
//...
Looking for 'gcc'

nm_file_name        = /usr/bin/nm
strip_file_name     = /usr/bin/strip
c_file              = a.out.cdtor.c
o_file              = a.out.cdtor.o/usr/bin/ld
ld: warning: platform not specified
ld: warning: -arch not specified
ld: warning: No platform min-version specified on command line
ld: no object files specified
collect2: error: ld returned 1 exit status

看起来好了，再试试编译

$  gcc-14 test.c -o t && ./t
Hello Cruel World!

完美解决！！

这个anaconda的ld和系统的是不匹配的，但是它为了penv把这个替换了，结果collect2使用了它设置的工具链的ld. 然后引起这个问题。

这个python连gcc也搞乱了，真是服，自己乱就好了。为什么祸害别人？

本文希望可以帮到需要的人，要是遇到这个的，可能原因不大一样，但是这个文章把debug和定位的方法和原理都告诉大家了，祝大好运！
