When attempting to compile courier-imap-4.4.1 on Solaris 9 using the Sun
Studio 12 compiler I ran into the following compilation error:
cc -I./.. -I.. -g -o couriertls starttls.o argparse.o -Wl,-lsocket
-Wl,-lnsl -L/usr/local/ssl/lib -L/usr/local/lib ./.libs/libcouriertls.a
-lssl -lcrypto -lnsl ./.libs/libspipe.a ../rfc1035/librfc1035.a
../md5/.libs/libmd5.a ../random128/.libs/librandom128.a
../numlib/.libs/libnumlib.a ../liblock/.libs/liblock.a
../soxwrap/libsoxwrap.a -lsocket -R/usr/local/ssl/lib -R/usr/local/lib
Undefined first referenced
symbol in file
setenv starttls.o
This is because the native libc on solaris 9 does not have a setenv().
However, putenv() can equivalently be used in its place. I wrote the
attached patch to work around this issue replacing the setenv function
calls with equivalent putenv calls.
If this patch provides the same functionality would it be possible to have
these changes incorporated into a future release, so that courier-imap can
be compiled on solaris 9 systems.
