Im assuming that on some platforms, adding -pthreads to the gcc command l= ine causes -lpthreads to be added by gcc automatically.

Hi, all...

I built (rather quickly, I might add) Privoxy 3.0.33, which is latest= =20
stable. I was initially stuck with a bunch of undefined symbol errors= for=20
pthread constructs, even though I did have pthread-devel installed=20
(0.2.6-1). (And yes, -pthread was specified in LDFLAGS.)

In GNUmakefile, there is a section:

# PThreads library, if needed.
PTHREAD_LIB =3D

I found that I actually had to set this to the absolute path to pthre= ad.a,=20
and I'm left wondering why. If pthread.a could not have been found, w= hy=20
didn't configure balk at that? More importantly, why wouldn't this ha= ve been=20
locatable?

Neither LD_LIBRARY_PATH nor -Lj:/usr/lib (on the gcc command line) no= r=20
-lpthread seemed to be able to find the pthreads library.

Here's the linker command which succeeds:

gcc.exe -pthread -o privoxy.exe actions.o cgi.o cgiedit.o cgisimple.= o=20
deanimate.o encode.o errlog.o \
filters.o gateway.o jbsockets.o jcc.o list.o loadcfg.o loaders.o=20
miscutil.o parsers.o ssplit.o urlmatch.o \
client-tags.o pcrs.o -llibgcc -lz -lpcre -lpcreposix=20
j:/usr/lib/pthread.a

Surely, I must be missing something very simple, here, but it is esca= ping=20
me, now.

TIA
