Hi guys,
Im assuming that on some platforms, adding -pthreads to the gcc command
line causes -lpthreads to be added by gcc automatically.
See:
https://stackoverflow.com/questions/2127797/significance-of-pthread-flag-when-compiling It would appear that even though our built-in specs understand pthread, we
don't understand it quite as fully as gcc on other platforms.
I see some configure scripts doing 3 or 4 pthread checks before deciding on the one to use for us.
BTW, doesn't privoxy have native OS/2 threads support or was it removed?
Dave
Hmmm... Using the configure option:
--disable-pthread
configure gives me the following ominous message:
checking pthread.h presence... yes
checking for pthread.h... yes
configure: WARNING: pthreads seem to be available but you are using --disable-pthread.
configure: WARNING: This is almost always a mistake and can render Privoxy unacceptable slow.
configure: WARNING: Also various Privoxy features only work when using threads and won't even compile
without them.
Compiling, I get (as a start):
gcc.exe -c -pipe -g -O2 -Zexe -DNDEBUG -Wall cgisimple.c -o cgisimple.o
cgisimple.c: In function 'cgi_show_client_tags':
cgisimple.c:376:10: warning: implicit declaration of function 'privoxy_mutex_lock' \
[-Wimplicit-function-declaration]
376 | privoxy_mutex_lock(&client_tags_mutex);
I'm not sure what else might need to be done to use native threads vs POSIX. I'll re-read configure as time permits.
Thanks for the suggestion.
PS - I'll bet this just builds fine with EMX. LOL
