I would imagine that there are more dependencies needed than just a C compiler and awk.
The way the code is set up to blindly fire CAP REQ :echo-message and CAP END before NICK and USER, which can lead to * being used in the ACK response (or even NAK) which confuses jjc and leads it to hang. The lines responsible are: https://github.com/aaronNGi/jj/blob/master/jjc#L321-L322
It would be ideal to either do a proper CAP LS (302) negotiation and only request echo-message if it is listed, or at the very least, handle cases where the nickname can be a * . this might also happen if one uses a nickname which is already in use while connecting, amongst other possible cases.
The "hanging" behavior is especially noticeable on current UnrealIRCd (6) releases which all have echo-message available by default. If desired or necessary, I can gladly provide a link to my own Unreal 6 instance for testing purposes.
EDIT: It may also be that one's own (U)UID is used in place of a nickname (possibly at least), although untested if jjc handles cases where it is referred to as by a different "nickname" (like (U)UID, enforced nickname by the server) when said other nickname is not * .
The compile succeeds after adding #include <stdint.h>
.

cc
is clang
on OpenBSD
Utilizing locate
, I see /usr/include/sys/socket.h
present.
I also tried with CC = egcc
in Makefile
(egcc is gcc from repo to distinguish it from gcc from base),
and gmake
, same:
gmake
CC -o jjd
egcc -o jjd jjd.o -s -L/usr/lib -lc -lsocket
ld: error: unable to find library -lsocket
collect2: error: ld returned 1 exit status
gmake: *** [Makefile:21: jjd] Error 1
function parse_bold(s,
tail)
{
tail = s
s = ""
while (match(tail, "\002[^\002]*\002")) {
s = s substr(tail, 1, RSTART - 1) "\033[1m"
s = s substr(tail, RSTART + 1, RLENGTH - 2) "\033[m"
tail = substr(tail, RSTART + RLENGTH)
}
return s tail
}
This function reads text with irc escape sequence, and returns the same string with the ^B
converted to \033[1m
or \033[m
(if beginning or end).
Text with ^Bbold^B characters
-> Text with \033[1mbold\033[m characters
