Hello Martin,

I removed ppl, so all that is left is cloog 0.18.0.  I'm having the  
same issue I have when building cloog 0.18.0 in the past. I usually  
build and install isl separately. Cloog 0.18.0 seems to have the habit  
of not being able to link against the isl that is shipped and built  
within the cloog source tree. Have you noticed this?

Configure states:

checking which isl to use... bundled


=== configuring in isl (/mnt/clfs/sources/cloog-0.18.0/isl)

configures isl..........

Making all in isl

builds isl.........

a bunch of undefined references for cloog isl required by the isl  
library.

hah! Silly build system!

libtool: link: x86_64-unknown-linux-gnu-gcc -m64 -Wall -O3 -fomit- 
frame-pointer -malign-double -fstrict-aliasing -ffast-math -o .libs/ 
cloog cloog.o  -L/tools/lib ./.libs/libcloog-isl.so /tools/lib/ 
libgmp.so -Wl,-rpath -Wl,/tools/lib
/mnt/clfs/cross-tools/bin/../lib/gcc/x86_64-unknown-linux-gnu/ 
4.8.0/../../../../x86_64-unknown-linux-gnu/bin/ld: warning: libisl.so. 
10, needed by ./.libs/libcloog-isl.so, not found (try using -rpath or - 
rpath-link)
./.libs/libcloog-isl.so: undefined reference to  
`isl_basic_set_has_defining_equality'

I removed ppl, it wouldn't hurt to add isl before cloog. Although,  
this stumps me.

I don't see a way to tell it that the isl library to use is the  
bundled library it just built! Heh.
Sincerely,

William Harrington
