I've just built 10.3.1 ecl and found out the problem with ecl-config script:
vad@... ~ $ ecl-config --cflags
-Dlinux @DEBUG_CFLAGS@ -I/opt/ecl-10.3.1-s/include/
vad@... ~ $ ecl-config --ldflags
@LDRPATH@ -L/opt/ecl-10.3.1-s/lib/ -lecl -ldl -lm
vad@... ~ $
This extra @xxx@ stuff then substituted into "gcc" command line, which then gives an error about wrong compilation file, which, in turn, makes difficulties with embedding...
BTW thanks for the release!
I am only occasional lisp user, but ecl project makes me feel better :)
At least it has great convenience for me in some aspects.
