Hi,

I wnat to upgrade to nginx 1.2.3 but it gives me the following error:

objs/src/core/ngx\_regex.o: In function `ngx_pcre_free_studies': /usr/local/src/nginx-1.2.3/src/core/ngx_regex.c:307: undefined reference to`pcre\_free\_study’  
collect2: ld returned 1 exit status  
make[1]: \*\*\* [objs/nginx] Error 1  
make[1]: Leaving directory `/usr/local/src/nginx-1.2.3’  
make: \*\*\* [build] Error 2

No I searched some, but I can’t find a solution.

It has to do something with the location of pcre.h. But when I do:

locate /pcre.h

It gives me:

/usr/include/pcre.h  
/usr/local/include/pcre.h

As you can see I have two versions of pcre.h running. I just wanted to  
remove one by doing a yum remove pcre, but then it wants to remove a  
lot of other packages.

Please help me, I am a newbee and don’t know what to do.

–  
Best regards,

Ruben
