First of all, thank you for taking your time to reply to this email. I tried it using the -l flag. The config file was found in the directory before that. Below is the command I executed.
$ gcc -I /home/user/Desktop/gnupg-1.4.13 -l/home/user/Desktop/gnupg-1.4.13 mpi-pow.c Now it's throwing the below error >In file included from mpi-pow.c:32: >mpi-internal.h:32:10: fatal error: mpi.h: No such file or directory > 32 | #include "mpi.h" > | ^~~~~~~ >compilation terminated. I tried copying the header file mpi.h into the directory gnupg-1.4.13 and compiling the mpi-pow.c program, now the error is like given below: >In file included from mpi-internal.h:32, > from mpi-pow.c:32: >mpi.h:34:10: fatal error: iobuf.h: No such file or directory > 34 | #include "iobuf.h" > | ^~~~~~~~~ Is there anything wrong with the way I used the -l flag ? If so could anyone guide me in the right direction? On Wed, 30 Mar 2022 at 21:19, Robert J.
