NGINX 1.0.3 compile error: src/core/ngx crypt.c: In function ‘ngx crypt apr1’

dubstep · May 27, 2011, 11:30am

Hi,

i’m having problems compiling the latest stable source 1.0.3.

How to reproduce:

cd
./configure
make

make output is attached in log.txt

I do not have any problems compiling stable source 1.0.2

Is suspect this issue beeing a bug. Can somebody confirm this?

Thanks in advance!

Cheers,
DJ

Sorry for the breakage. BTW, it’s probably good idea to finally
branch stable-1.0 and start releasing 1.1.*.

It seems you looked at FreeBSD prior to 7.0-CURRENT,
this has been changed on 17.01.2006.
