I installed Crypto++ from source as follows: 1. git clone https://github.com/weidai11/cryptopp.git 2. cd cryptopp 3. Uncommented the CXX flag line in GNUmakefile that adds "-stdlib=libc++" because I am using XCode. 4. make -j 8 (8 = value of $(nproc) on my machine if it were linux) 5. sudo make install
The make and install complete without errors. I confirmed that /usr/local/lib contains libcryptopp.a. When I try to use libcryptopp in a project (in a different directory from the cryptopp install), clang (Apple Clang 12.0.0) can't find it. I get the following error message: + LD lib/crypto_bench ld: library not found for -l:libcryptopp.a clang: *error: *linker command failed with exit code 1 (use -v to see invocation) This is the output of gcc --version (gcc is linked to clang but not directly used): Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1 Apple clang version 12.0.0 (clang-1200.0.32.29) Target: x86_64-apple-darwin19.6.0 Thread model: posix InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin I also tried updating my PATH variable in bash_profile with the location of libcryptopp as follows, then source'd bash_profile again: export PATH="/usr/local/lib:$PATH" However, this resulted in the same error as before when I tried to compile the project. I've spent several hours googling and haven't been able to find a fix, and I'm wary of manually symlinking the file because it can break other installs on my laptop. Any help with fixing this issue would be much appreciated. -- You received this message because you are subscribed to the Google Groups "Crypto++ Users" group.
