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); ^ thread-sample.c:50:9: warning: implicit declaration of function ‘apr_thread_create’ [-Wimplicit-function-declaration] rv = apr_thread_create(&thd_arr[i], thd_attr, doit, INT_TO_POINTER(i), mp); ^ thread-sample.c:55:9: warning: implicit declaration of function ‘apr_thread_join’ [-Wimplicit-function-declaration] rv = apr_thread_join(&rv, thd_arr[i]); ^ thread-sample.c: In function ‘doit’: thread-sample.c:71:5: warning: implicit declaration of function ‘apr_thread_exit’ [-Wimplicit-function-declaration] apr_thread_exit(thd, APR_SUCCESS); ^ /tmp/cc9d71E0.o:thread-sample.c:(.text+0x14): undefined reference to `apr_initialize' /tmp/cc9d71E0.o:thread-sample.c:(.text+0x3b): undefined reference to `apr_pool_create_ex' /tmp/cc9d71E0.o:thread-sample.c:(.text+0x52): undefined reference to `apr_threadattr_create' /tmp/cc9d71E0.o:thread-sample.c:(.text+0x9d): undefined reference to `apr_thread_create' /tmp/cc9d71E0.o:thread-sample.c:(.text+0x114): undefined reference to `apr_thread_join' /tmp/cc9d71E0.o:thread-sample.c:(.text+0x161): undefined reference to `apr_terminate' /tmp/cc9d71E0.o:thread-sample.c:(.text+0x19f): undefined reference to `apr_thread_exit' collect2: error: ld returned 1 exit status 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.
