Undefined reference to evhttp_response_code_

[jdoe0000000]

Compiling tunsocks against libevent-2.1.12 fails with the following error messages:

/usr/bin/ld: src/http/http.o: in function `client_send_error':
/tmp/tunsocks/src/http/http.c:60: undefined reference to `evhttp_response_code_'
/usr/bin/ld: /tmp/tunsocks/src/http/http.c:69: undefined reference to `evhttp_send_page_'
/usr/bin/ld: src/http/http.o: in function `proxy_req_server_headers_done':
/tmp/tunsocks/src/http/http.c:136: undefined reference to `evhttp_response_code_'

These symbols have been part of libevent since 2.1.1.

I have the same issue here (Arch Linux, libevent 2.1.12). I've found that recently Arch stopped providing a static library for libevent (libevent.a), which may explain why the issue is only appearing now. Since these functions are not part of the public API of libevent, they are not exported, and therefore you cannot rely on them being available when linking against the dynamic library (libevent.so). Would it be possible to use public functions instead?

Same issue on Debian 12. Installed libevent 2.1.12 and libevent-dev, still seeing lots of "undefined reference to `evhttp_ ..." errors.

UPD: solved by editing the makefile, I added -levent linker flag which is missing for some reason.
