Hello, I’m installing Nginx 0.8.40 on Solaris 10 with SSL module enabled. But configure command (./configure --prefix=/export/home/tomcat/nginx –with-http\_ssl\_module) failed with following messages in autoconf.err. ========================= checking for OpenSSL library ## objs/autotest.c:4:25: openssl/ssl.h: No such file or directory #include #include #include int main() { SSL\_library\_init(); return 0; } * * * # gcc -D\_FILE\_OFFSET\_BITS=64 -lsocket -lnsl -o objs/autotest objs/autotest.c -lssl -lcrypto I have installed openSSL and is available on the PATH. OpenSSL\> version OpenSSL 0.9.7d 17 Mar 2004 Do I need to specify some kind environment variable for SSL library? What’s the default path Nginx will look for OpenSSL library?

As opposite to PCRE library, nginx does not try to search OpenSSL in several places. It’s usually /usr/include and /usr/lib. – Igor S. > **[Igor Sysoev](http://sysoev.ru/en/)** ---

Thanks a lot for the quick response. After specifying -I and -L for OpenSSL includes and library, it found the SSL library, although I still can see there are some error messages in autoconf.err. make and make install seem working too. I didn’t spot any error in the console. But when I was trying to start nginx, it immediately print out following and failed. ld.so.1: nginx: fatal: libpcre.so.0: open failed: No such file or directory Killed William ## Igor S.
