Interesting cross-compiler behaviour - Gpc

10 Apr 1999


      I'm trying to build a Linux/Intel compiler to generate PowerPC/AIX
binaries (as part of my ongoing quest not to use the Codewarrior pascal
compiler). I've been following the instructs in http://www.objsw.com/CrossGCC.
These instructions work fine when building a non-gpc-patched version
of egcs 1.1.1, but the gpc-patched version goes into some sort of recursive
make - it spews out the following over and over again, making a new make
each time, until it hits about 200 make processes, whereupon they all
exit and the process aborts with an error. The circular dependency thing
looks interesting...any ideas?

if [ -f libgcc2.ready ] ; then \
        true; \
else \
        touch libgcc2.ready; \
fi
make[1]: Circular cplib2.ready <- pascal dependency dropped.
