SIMH diesn't compile "undefinied reference to [fmod|clock_getres" although -lrt/-lm

Hello,

I wanted to compile SIMH (http://simh.trailing-edge.com/), but following happens:

Code:

<thosch97@darkstar:~/simh>

zsh 6 % make    

gcc -std=c99 -U__STRICT_ANSI__ -g -lrt -lm -D_GNU_SOURCE -I . PDP1/pdp1_lp.c PDP1/pdp1_cpu.c PDP1/pdp1_stddev.c PDP1/pdp1_sys.c PDP1/pdp1_dt.c PDP1/pdp1_drm.c PDP1/pdp1_clk.c PDP1/pdp1_dcs.c scp.c sim_console.c sim_fio.c sim_timer.c sim_sock.c sim_tmxr.c sim_ether.c sim_tape.c -I PDP1 -o BIN/pdp1 

/tmp/ccANdat7.o: In function `drm':

/home/thosch97/simh/PDP1/pdp1_drm.c:205: undefined reference to `fmod'

/home/thosch97/simh/PDP1/pdp1_drm.c:236: undefined reference to `fmod'

/home/thosch97/simh/PDP1/pdp1_drm.c:246: undefined reference to `fmod'

/home/thosch97/simh/PDP1/pdp1_drm.c:257: undefined reference to `fmod'

/tmp/ccmSIFWD.o: In function `sim_os_ms_sleep_init':

/home/thosch97/simh/sim_timer.c:306: undefined reference to `clock_getres'

collect2: ld gab 1 als Ende-Status zurück (ld exited with 1)

make: *** [BIN/pdp1] Fehler 1 (error 1)

I'm using gcc-Version 4.6.1 (Ubuntu/Linaro 4.6.1-9ubuntu3) on 3.0.0-12-generic/Ubuntu 11.10

What is wrong with it?
Thank you for you help,

1) sudo apt-get install g++-4.4

2) Edit line 15 in 'makefile' from

Code:

CC = gcc -std=c99 -U__STRICT_ANSI__ -g $(OS_CCDEFS) -I .

to :

Code:

CC = gcc-4.4 -std=c99 -U__STRICT_ANSI__ -g $(OS_CCDEFS) -I .

... Then 'make' will create all 26 binaries to the BIN/ directory.

.

Thanks! It works great now!
(Well, that also explains why it worked on a Sun Ultra5 with Debian Lenny: it has gcc version 4.3.2 (Debian 4.3.2-1.1))
