I got the following make error:-
/usr/bin/ld: cannot find -lXmu
collect2: ld returned 1 exit status
make: *** […/…/bin/linux/release/fluidsGL] Error 1
and fixed it by running:-
sudo apt-get install libxmu-dev libxmu6
I read a couple of other posts of this forum about resolving this type of compilation problem and they made me think I had to edit various files and compilation options etc. etc. but then found the above solution on the wider web and it worked for me. This was on xubuntu 8 btw.
Also (in case it help you) had to downgrade from gcc-4.3 to gcc-4.1 and g+±4.3 to g+±4.1 which i did using apt-get remove and apt-get install for each of them, and do
sudo apt-get install freeglut3-dev
to get everything compiling OK.
BTW - I’m sure most Linuxy people would know to install libxmu, but to us newbies might be helpful to read above
