I have no Solaris around, hence I didn't see that problem :-) My output: cd pppd; make all make[1]: Entering directory `/srv/src/net/ppp/pppd' musl-gcc -O2 -pipe -Wall -g -DHAVE_PATHS_H -DIPX_CHANGE -DHAVE_MMAP -I../include '-DDESTDIR="/usr/local"' -DCHAPMS=1 -DMPPE=1 -DHAS_SHADOW -DHAVE_CRYPT_H=1 -I/usr/include/openssl -DHAVE_MULTILINK -DUSE_TDB=1 -DPLUGIN -DINET6=1 -DMAXOCTETS -c -o sha1.o sha1.c In file included from sha1.c:21:0: ../include/net/ppp_defs.h:182:5: error: unknown type name ‘time_t’ time_t xmit_idle; /* time since last NP packet sent */ ^ ../include/net/ppp_defs.h:183:5: error: unknown type name ‘time_t’ time_t recv_idle; /* time since last NP packet received */ ^ make[1]: *** [sha1.o] Error 1 make[1]: Leaving directory `/srv/src/net/ppp/pppd' the time_t type isn't defined while being used. AFAIK, time_t is defined in time.h Wrapping the include inside a #ifdef SOLARIS seems the most correct solution. including sys/time.h works, but that is rather by accident at this moment. Kind regards, Kurt
