在构建使用autoconf的OpenFST软件包之前，我正在运行./configure命令。
检查ar界面时，脚本失败：
$ ./configure
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... ./install-sh -c -d
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking whether make supports nested variables... yes
checking for style of include used by make... GNU
checking for gcc... gcc
checking whether the C compiler works... yes
checking for C compiler default output file name... a.out
checking for suffix of executables...
checking whether we are cross compiling... no
checking for suffix of object files... o
checking whether we are using the GNU C compiler... yes
checking whether gcc accepts -g... yes
checking for gcc option to accept ISO C89... none needed
checking whether gcc understands -c and -o together... yes
checking dependency style of gcc... gcc3
checking for ar... ar
checking the archiver (ar) interface... unknown
configure: error: could not determine ar interface
这似乎与this question有关，但是我不明白如何使脚本使用正确的MacOS文件，以便配置能够正常工作。
答案 0 :(得分：1)
查看config.log，结果发现问题与使用ar中错误的ranlib和错误/opt/local/bin/而不是/usr/bin中的错误有关。 / p>
运行此解决了问题：
sudo mv /opt/local/bin/ranlib /opt/local/bin/ranlib-backup-2019-02-09
sudo mv /opt/local/bin/ar /opt/local/bin/ar-backup-2019-02-09
