Hello Marco,

After getting some replies about mapcache in the mapserver forum (http://osgeo-org.1560.x6.nabble.com/compiling-error-core-c-in-mapcache-with-cygwin-td5179881.html#a5180931), I have the impression that apr has some issues in cygwin. Using this "thread-sample.c" (http://dev.ariel-networks.com/apr/apr-tutorial/sample/thread-sample.c) with

gcc -Wall $(apr-1-config --cflags --cppflags --includes --link-ld)  thread-sample.c

I got:

$ gcc -Wall $(apr-1-config --cflags --cppflags --includes --link-ld) thread-sample.c
thread-sample.c: In function ‘main’:
thread-sample.c:46:5: warning: implicit declaration of function ‘apr_threadattr_create’ [-Wimplicit-function-declaration]
     apr_threadattr_create(&thd_attr, mp);

Would you have a magic hack to get this working? it seems that this .c test file compiles with no problems in some linux environments like slackware linux. Thanks in advance,

Gery
