Unable to configure PCSC - relay on mac

[siddhantmishra1305]

I am trying to configure pcsc-relay on macOS but getting below error:

loading "libpcsclite_real.so.1" failed: dlopen(libpcsclite_real.so.1, 0x0001): tried: 'libpcsclite_real.so.1' (no such file), '/System/Volumes/Preboot/Cryptexes/OSlibpcsclite_real.so.1' (no such file), '/usr/lib/libpcsclite_real.so.1' (no such file, not in dyld cache), 'libpcsclite_real.so.1' (no such file) Could not connect to PC/SC Service Internal error. Compiled without support for libnfc AFAIK libpcsclite is only available for linux.

So is pcsc-relay even supported on mac ?

[frankmorgner]

it should be detected automatically. What's the output of ./configure?

[siddhantmishra1305]

On running ./configure I got below error:



configure: error: winscard.h not found, install PC/SC Lite or similar or use ./configure PCSC_CFLAGS=...
 


I ran below command to set the variables and tried again.

export PKG_CONFIG_PATH="/opt/homebrew/opt/pcsc-lite/lib/pkgconfig”
export CPPFLAGS="-I/opt/homebrew/opt/pcsc-lite/include"  

export LDFLAGS="-L/opt/homebrew/opt/pcsc-lite/lib"



After setting above variables pcsc-relay got configured successfully.

[frankmorgner]

you need to install XCode with its PC/SC headers/libs. PCSC-Lite (the homebrew project) is not tightly integrated into the OS, I think.

Okay so I just built PCSC-lite repo alocally and then pcsc-relay started working fine.
