compiling error core.c in mapcache with cygwin
Locked
 
|
Hello,
When installing mapcache in cygwin, `make` produced: /opt/mapcache/mapcache-rel-1-2-1/lib/core.c: In function ‘mapcache_prefetch_tiles’: /opt/mapcache/mapcache-rel-1-2-1/lib/core.c:81:3: error: unknown type name ‘apr_thread_t’ apr_thread_t **threads; ^ /opt/mapcache/mapcache-rel-1-2-1/lib/core.c:82:3: error: unknown type name ‘apr_threadattr_t’ apr_threadattr_t *thread_attrs; ^ /opt/mapcache/mapcache-rel-1-2-1/lib/core.c:83:7: warning: unused variable ‘nthreads’ [-Wunused-variable] int nthreads; ^ /opt/mapcache/mapcache-rel-1-2-1/lib/core.c:82:21: warning: unused variable ‘thread_attrs’ [-Wunused-variable] apr_threadattr_t *thread_attrs; ^ /opt/mapcache/mapcache-rel-1-2-1/lib/core.c:81:18: warning: unused variable ‘threads’ [-Wunused-variable] apr_thread_t **threads; ^ I searched for some hints about this error but didn't find anything. Looking for `apr_thread_t` and cygwin, I found some pages pointing to an error with apache, but not really sure if apache has something to do here. thanks for any hints on this, Gery _______________________________________________ mapserver-users mailing list [hidden email] http://lists.osgeo.org/mailman/listinfo/mapserver-users |

Thanks Andy for the reply, I do have apr, no idea if it's the generic lib or webserver one but they are 1.4 version: Gery@gery /opt/mapcache/mapcache-rel-1-2-1/build $ cygcheck -c | grep apr apr1 1.4.8-1 OK aprutil1 1.5.4-1 OK libapr1 1.4.8-1 OK libapr1-debuginfo 1.4.8-1 OK libapr1-devel 1.4.8-1 OK libaprutil1 1.5.4-1 OK libaprutil1-debuginfo 1.5.4-1 OK libaprutil1-devel 1.5.4-1 OK My apache version and details here: Gery@gery /opt/mapcache/mapcache-rel-1-2-1/build $ apachectl2 -V Server version: Apache/2.2.29 (Unix) Server built: Sep 17 2014 17:10:18 Server's Module Magic Number: 20051115:36 Server loaded: APR 1.4.8, APR-Util 1.5.4 Compiled using: APR 1.4.8, APR-Util 1.5.2 Architecture: 32-bit Server MPM: Prefork threaded: no forked: yes (variable process count) Server compiled with.... -D APACHE_MPM_DIR="server/mpm/prefork" -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D DYNAMIC_MODULE_LIMIT=128 -D HTTPD_ROOT="/usr" -D SUEXEC_BIN="/usr/bin/suexec" -D DEFAULT_PIDLOG="/var/run/apache2/httpd2.pid" -D DEFAULT_SCOREBOARD="logs/apache_runtime_status" -D DEFAULT_LOCKFILE="/var/run/apache2/accept.lock" -D DEFAULT_ERRORLOG="logs/error_log" -D AP_TYPES_CONFIG_FILE="/etc/apache2/mime.types" -D SERVER_CONFIG_FILE="/etc/apache2/httpd.conf" Based on Stephen's answer (http://stackoverflow.com/questions/27755442/compiling-error-core-c-in-mapcache-with-cygwin), I should compile mapcache only as cgi (ie., no apache module), so I used: cmake .. -DCMAKE_LEGACY_CYGWIN_WIN32=0 -DWITH_SQLITE=0 -DWITH_MAPSERVER=1 -DMAPSERVER_LIBRARY="/opt/mapserver/mapserver-6.4.1/build/libmapserver.dll.a" -DCMAKE_PREFIX_PATH="/opt/mapserver/mapserver-6.4.1;" -DWITH_APACHE=0 but I get the same error pointing to core.c.

sorry for bumping this post, but any clues about this issue with core.c? any ideas how to solve this core.c error message with the cygwin details I previously posted?
It'd be great your support on this, thanks in advance. |

What apr version are you using? On Jan 3, 2015 10:15 PM, "Gery ." <[hidden email]> wrote:

Thanks Thomas, I just got an email from the Cygwin mailing list saying that threads were not enabled in the APR library because the unit tests didn't pass with them, so that's the problem as you pointed out. I'd like to hack the mapcache codebase but no idea how to start hacking it to get it working without threads, but if you could give me some hints such as what files are involved (I imagine only core.c), which sections/lines would be involved, sure I could do it, I'd appreciate it. If I get that working, sure other people can test that in Cygwin and your audience will eventually increase :) Gery Sent from my iRon From http://mail-archives.apache.org/mod_mbox/apr-dev/201209.mbox/%3C4994179EC7ED6843AAB0A30A1639E7F825143612EF@...%3E it would seem that threads are not supported by Apr on cygwin.

Sorry for bumping this old thread, but any chances to get support in order to change core.c so mapcache can work in cygwin without (apr) threads enabled? would you have a core.c patched version? Thanks for any pointers.
