While linking the crda.o and libreg.so, first put crda.o and then -lreg. This fixed the below error: # make GEN keys-gcrypt.c Trusted pubkeys: pubkeys/linville.key.pub.pem CC libreg.so CC crda.o LD crda crda.o: In function `main': crda/crda.c:196: undefined reference to `reglib_get_rd_alpha2' collect2: ld returned 1 exit status make: *** [crda] Error 1 Note: This still doesn't fix the below error (will send another mail) CHK /usr/lib/crda/regulatory.bin Database signature verification failed.
