I first tried with including it with the silc-toolkit before building and
install it. Then I tried with chat/gaim. But neither worked.
Then I saw that patch-ad removes the -ldl from the configure script.
My CONFIGURE_ENV has:
PTHREAD_CFLAGS=\ -pthread\ PTHREAD_LDFLAGS=\ -pthread
PTHREAD_LIBS=-lpthread\ -lrt PTHREADBASE=/usr
DL_CFLAGS="" DL_LDFLAGS="" DL_LIBS=""
My libdl comes from pkgsrc installed glibc (my package). I don't have a
buildlink3.mk file for it and I install to /usr. So I set
I see mk/dlopen.builtin.mk has:
# No need to add this to BUILDLINK_LIBS.dl since most GNU configure
# scripts already check for -ldl themselves.
And the gaim configure script does check for libdl and also it does:
pkg-config --libs "silcclient" which returns:
-L/usr/lib/silc -lsilcclient -ldl -lpthread -lsilc
I don't know why it doesn't use the above -ldl and I don't know why it
doesn't use the -ldl is detected.
I will ask the gaim developers about this.
