Bug #80585 [Com]: Compile error - iconv dose not support errno

Edit report at https://bugs.php.net/bug.php?id=80585&edit=1 ID: 80585 Comment by: guillaume-php at outters dot eu Reported by: tomas at rybarik dot com Summary: Compile error - iconv dose not support errno Status: Open Type: Bug Package: *Compile Issues Operating System: OracleLinux 7 PHP Version: 8.0.0 Block user comment: N Private report: N New Comment: Tomas, could you please tell us what error is logged in the config.log? As suggested by cmg, this is a problem of detection; but in my case (FreeBSD 10.2, with "hand"-compiled GNU iconv 1.16 without pkgconfig), the detection program had no problem, rather it was its compile env that lacked a -liconv. So this could be circumvented by running an: export LDFLAGS="$LDFLAGS -liconv" before the configure. I _think_ that, like you, I had no problem compiling a PHP 7 in the same environment (so this detect failure would be a configure regression); but I cannot be certain.

Either you glic iconv does not support errno, or that support is wrongly detected. Consider to install and use libiconv. ------------------------------------------------------------------------ [2021-01-04 15:06:20] tomas at rybarik dot com Description: ------------ I'm unable to compile PHP 8.0.0 with enabled iconv.
