I eventually found this page which talked about downloading a special
toolchain from openwrt web site<br>
<br>
<a class="moz-txt-link-freetext" href="http://www.dd-wrt.com/phpBB2/viewtopic.php?t=61112">http://www.dd-wrt.com/phpBB2/viewtopic.php?t=61112</a><br>
<br>
I followed its instruction and successfully compiled a helloworld c
program and <br>
successfully RUN the helloworld binary on Netgear 3700 running DD-Wrt !<br>
<br>
I was overjoyed.<br>
<br>
Then I tried to modify the steps to compile fpc <br>
<br>
my toolchains is at /home/dennis/toolchains/staging_dir_mips/bin/<br>
and in this folder, there are files: mips-linux-ar and mips-linux-as<br>
so I <br>
make clean all CPU_TARGET=mips OS_TARGET=linux
BINUTILSPREFIX=/home/dennis/toolchains/staging_dir_mips/bin/mips-linux-<br>
<br>
but I got errors:<br>

I feel I am almost there. Any help on the above?<br>
