I have just learnt a few things installing Poly/ML on a Ubuntu 8.04 system freshly built from the Desktop CD:
- Ubuntu comes out of the CD with 3/4 of a C compiler. You get gcc, but not
libc, so you can compile hello-world.c but not link or run it. The configure script notices this. Installing the package libc6-dev fixes it.
- But, the configure script doesn't seem to check that there is a C++
compiler (perhaps it should???). The output from configure looked OK, but make fell over with an error:
../libtool: line 1281: g++: command not found
Installing the package g++ fixes this.
I've just fallen over this myself as a result of reinstalling Ubuntu on my 64-bit machine. Surprisingly there isn't a direct autoconf macro to test this but I've worked out the test to apply and added it to the configure script.
- But, poly builds and installs but won't run, because Ubuntu is one of those
systems that doesn't include /usr/local/lib on the library path, After starting again with "./configure --prefix=/usr", I have a working compiler.
It appears that autoconf does this by default. I don't know if there's a way to detect it. I made a note in some of the documentation somewhere about this. It's a particular problem if ldconfig doesn't include /usr/local/lib because the dynamic libraries won't be loaded.
