[OpenWrt-Devel] ICONV & ICONV_SET_TRANSLITERATE issue in trying to port suricata to openwrt

[Derek Werthmuller]

I'm working on porting suricata to openwrt and have run into an issue with
iconv.  It seems that there are different ways to invoke the ICONV
libraries.
Those porting suricata to freebsd had the same problem and error.
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=196720  From their patch
it looks like they were able to invoke iconv with

iconv:translit vs its default method

Is there a similar configuration method for openwrt Makefiles?

THe following is the error message I get while compiling.

htp_transcoder.c: In function 'htp_transcode_params':
htp_transcoder.c:68:5: warning: implicit declaration of function 'iconvctl'
