I am compiling a C++11 program with:

g++ -std=c++11 main.cpp -o main -I/opt/homebrew/Cellar/curlpp/0.8.1_1/include/ -Iinclude  -lcurl

Yet I am getting the following error:

Undefined symbols for architecture arm64:
  "curlpp::Cleanup::Cleanup()", referenced from:
      _main in main-18dda9.o
  "curlpp::Cleanup::~Cleanup()", referenced from:
      _main in main-18dda9.o
ld: symbol(s) not found for architecture arm64

What is the platform you are building the program for? What is the platform for which curlpp was built? Looks like you are cross-compiling, however you have not built the curlpp library for target platform.. Can you provide additional information about your build environment. – Dark Sorrow Aug 23 '22 at 14:00

Is it native build or are you cross-compiling? Are you using any package manager for library or are you manually building the library? – Dark Sorrow Aug 23 '22 at 14:08
I just ran brew install curlpp. Doesn't this install the native build? – Riccardo Perego Aug 23 '22 at 14:12
It should. Try running lipo -info library_name and post the output – Dark Sorrow Aug 23 '22 at 14:48
@DarkSorrow fatal error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo: can't open input file: curlpp (No such file or directory) – Riccardo Perego Aug 23 '22 at 15:03
Check if libcurlpp.a is available in the location in case of static build or libcurlpp.so in case of shared library. – Dark Sorrow Aug 23 '22 at 17:38
@DarkSorrow libcurlpp.a – Riccardo Perego Aug 23 '22 at 17:39
Is the file available at the mentioned location? – Dark Sorrow Aug 23 '22 at 18:39
@DarkSorrow What file? The thing that confuses me is that I am doing the exact same process to import other libraries (Boost library) and it works. – Riccardo Perego Aug 23 '22 at 18:41
Is libcurlpp.a located in the folder where you are searching for the library. – Dark Sorrow Aug 23 '22 at 18:57
@DarkSorrow No. The folder where I am searching is /opt/homebrew/Cellar/curlpp/0.8.1_1/include while the folder containing libcurlpp.a is /opt/homebrew/Cellar/curlpp/0.8.1_1/lib – Riccardo Perego Aug 23 '22 at 18:58
Go to the folder containing libcurlpp.a and type lipo -info libcurlpp.a – Dark Sorrow Aug 23 '22 at 19:03
@DarkSorrow Non-fat file: libcurlpp.a is architecture: arm64 – Riccardo Perego Aug 23 '22 at 19:45
Run uname -a and paste the output. – Dark Sorrow Aug 24 '22 at 12:02
Try also to give complete path of the library while building the program. – Dark Sorrow Aug 24 '22 at 12:03
