I tried to install r2frida using both methods in my macos 14.4.1, getting these errors, radare2 up to date, frida up to date.

libdl is available via libSystem in the dyldcache on macOS, and it builds fine here. Is your xcode up to date? or maybe you have a different broken compiler installed from brew? Try this

1$ vim a.c
0$ gcc a.c -ldl
0$ cat a.c
int main(void){return 0;}
0$

[Xplo8E]

$ gcc a.c -ldl
$ ./a.out
$ cat a.c
int main(void){return 0;}

it compiled fine.

[Xplo8E]

$ /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang a.c -ldl
ld: library 'dl' not found
clang: error: linker command failed with exit code 1 (use -v to see invocation)

but with clang

$ clang a.c -ldl

$ where clang
/usr/bin/clang

$ where gcc
/usr/bin/gcc

[Xplo8E]

this issue was fixed with

export SDKROOT="`xcrun --show-sdk-path`"

Closing because it seems like an issue in your toolchain setup. using gcc/clang builds fine in my macOS.

Thanks for investigating and posting the solution to the issue, that may hopefully help other users if affected.
