Mac OS X 11.6 (Big Bur) 上 RInside 的链接错误：找不到 pcre2-8 库

Question

这可能是安装 PCRE2 时出错（我使用“sudo port install pcre2”），但是当我为 RInside “制作”示例代码时，我得到：

$ make rinside_sample0
clang++ -mmacosx-version-min=10.13 -std=gnu++11 -I/Library/Frameworks/R.framework/Resources/include -I/Library/Frameworks/R.framework/Versions/4.0/Resources/library/Rcpp/include -I/Library/Frameworks/R.framework/Versions/4.0/Resources/library/RInside/include -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -Wall -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -I/usr/local/include   rinside_sample0.cpp   -L/usr/local/lib -F/Library/Frameworks/R.framework/.. -framework R -L/usr/local/lib -lpcre2-8 -llzma -lbz2 -lz -licucore -ldl -lm -liconv  -L/Library/Frameworks/R.framework/Resources/lib -lRblas -L/Library/Frameworks/R.framework/Resources/lib -lRlapack  /Library/Frameworks/R.framework/Versions/4.0/Resources/library/RInside/lib/libRInside.a -o rinside_sample0

德克，谢谢你的评论。你让我指出了正确的方向。我有两个旧版本的代码：pcre2 和 Rcpp。

我按照此处的说明安装了最新版本的“pcre2”：https://izziswift.com/how-to-install-pcre-development-headers-on-mac-osx/。

我下载了“pcre”10.39 版，cd 到那个目录，运行:

./configure
make
make install

之后编译了RInside中的例子，但是出现运行时错误：

$ ./rinside_sample0
Error: function 'Rcpp_precious_remove' not provided by package 'Rcpp'
Execution halted
$

一些搜索显示错误来自运行旧版本 (1.0.6) 的“Rcpp”。我进入 RStudio，输入“install.packages("Rcpp")”更新到版本 1.0.7，现在一切都运行了！

希望完成这些步骤会对遇到这些问题的其他人有所帮助。
