Hello,

When I try to compile httpd 2.4.53 with pcre2, I have the following error :
gcc    -DDARWIN -DSIGPROCMASK_SETS_THREAD_MASK -DDARWIN_10     -I. -I/Webserver/sources/httpd-2.4.53/os/unix -I/Webserver/sources/httpd-2.4.53/include -I/Webserver/sources/httpd-2.4.53/srclib/apr/include -I/Webserver/sources/httpd-2.4.53/srclib/apr-util/include -I/Webserver/ext/pcre2-10.40/include -I/Webserver/sources/httpd-2.4.53/modules/aaa -I/Webserver/sources/httpd-2.4.53/modules/cache -I/Webserver/sources/httpd-2.4.53/modules/core -I/Webserver/sources/httpd-2.4.53/modules/database -I/Webserver/sources/httpd-2.4.53/modules/filters -I/Webserver/sources/httpd-2.4.53/modules/ldap -I/Webserver/sources/httpd-2.4.53/modules/loggers -I/Webserver/sources/httpd-2.4.53/modules/lua -I/Webserver/sources/httpd-2.4.53/modules/proxy -I/Webserver/sources/httpd-2.4.53/modules/http2 -I/Webserver/sources/httpd-2.4.53/modules/session -I/Webserver/sources/httpd-2.4.53/modules/ssl -I/Webserver/sources/httpd-2.4.53/modules/test -I/Webserver/sources/httpd-2.4.53/server -I/Webserver/sources/httpd-2.4.53/modules/md -I/Webserver/sources/httpd-2.4.53/modules/arch/unix -I/Webserver/sources/httpd-2.4.53/modules/dav/main -I/Webserver/sources/httpd-2.4.53/modules/generators -I/Webserver/sources/httpd-2.4.53/modules/mappers  -c /Webserver/sources/httpd-2.4.53/server/buildmark.c

(no error with pcre 8.45)

I use this configure :
./configure --prefix=/Webserver/ext/httpd-2.4.53 --with-pcre=/Webserver/ext/pcre2-10.40/bin/pcre2-config --with-ssl=/Webserver/ext/openssl-1.1.1h --with-included-apr --with-socache_shmcb --enable-setenvif --enable-rewrite --disable-a-lot-of-things

I'd like to find the source of the problem but I wouldn't know where to start…

Thanks
Arnaud
